K1-B0

K1-B0 (キーボ), also known as Keebo and Ki-Bo, is a student in the Ultimate Academy for Gifted Juveniles and a participant of the Killing School Semester featured in Danganronpa V3: Killing Harmony. His title is the Ultimate Robot (超高校級の「ロボット」 lit. Super High School Level Robot).

Creation
K1-B0 was created by an organization that created and featured Killing Games for the entire world's entertainment, Team Danganronpa. They decided that the main gimmick for the 53rd Season of Danganronpa would be "audience participation", K1-B0 was created for that role. The prominent ahoge on the top of his head acted as an antenna that received signals. This would end up being the "inner voice" that K1-B0 would hear many times throughout the events of the Killing Game, nothing more than an audience survey. His eyes would also act as a camera for the viewers, letting them see the Killing Game from his perspective.


 * Fabricated Past

In order for him to fulfill his role as the "connector" to the outside world, K1-B0's memory of being a part of Team Danganronpa was erased and fabricated just like any other Killing Game participant. His memories and personality were fabricated as follows:

Professor Idabashi, the leading expert in robotics engineering, created K1-B0 to be the culmination of all his research and work. He was meant to be a robot more human than any other robot before. Initially, K1-B0 had no knowledge nor awareness, and was only capable of displaying a very narrow spectrum of human emotions. The plan was to raise and develop him like a parent would their own child. However, a few years passed, and there was no improvement in his mental state.

One day, an unpredictable accident occurred during a routine experiment. K1-B0's programming went rogue and he ended up seriously maiming the professor, but fortunately he survived. After hurting the professor, K1-B0 was suddenly overcome by immense sadness, especially considering that the First Law of Robotics stated 'a robot must not harm a human being'. Even though K1-B0 wasn't punished for breaking that rule, he nevertheless felt sadness and blamed himself, feeling extremely guilty. For the first time, he understood how it felt to feel human emotions, and at that moment his AI suddenly reset as if committing suicide. He became similar to a newborn infant once again, with all of his memories deleted. In his "next life", K1-B0 called it the day of his own "death" and the day of his true "birth". After learning the story from the professor, he assumed that perhaps he had wanted to be "reborn" as the professor's son once again.

K1-B0's strength was considerably weakened after the incident, described as being similar in strength to an average senior citizen. This time, his AI matured accordingly and he learned and developed as his creator raised him like his own child, with K1-B0 considering the professor his father. Eventually, the professor even sent him to attend Īdabashi Industries High School (飯田橋工業高校) and he was recognized as being Ultimate even as a robot. However, he fears that other students will discriminate him because he is a robot.

The Gofer Project
Part of the fake backstories created for K1-B0 and the other fifteen students was The Gofer Project, which supposedly happened before the Killing Game started. It was initiated by heads of nations from all over the world after countless meteorites crashed into Earth, spreading a deadly virus all throughout the atmosphere. To try and preserve the last vestiges of mankind before the Earth’s destruction, the government decided to select sixteen talented students chosen by the Ultimate Initiative that also somehow happened to be immune to the virus, put them in a spaceship colony, and have them escape before the Earth's destruction. K1-B0 was among these sixteen individuals despite the obvious fact, that he was a robot.

Despite being chosen to participant however, K1-B0 and the other fifteen participants had no intentions of going along with the plan, not wanting to abandon their loved ones. As a result, K1-B0 chose to forget about his Ultimate talent and decided to live as a normal high school student.

Around that time an extremist cult came into power. They believed that the meteorites were a punishment humanity brought upon itself, and having heard of The Gofer Project, tried to stop it. As a result, the “Ultimate Hunt” started and spread throughout the world, and the sixteen students selected for the Gofer Project were hunted down.

The government then decided to counter the situation by faking the students' deaths, calming down the “Ultimate Hunt” while providing protection to the students. The Gofer Project was then put into action while the Earth was being destroyed by meteorites. K1-B0 and the others went to space in the massive ark, the true form of Ultimate Academy for Gifted Juveniles, and were put to a cold sleep for several decades.

Much later on in Chapter 5, after the remaining participants cleared the Death Road of Despair, Kokichi Oma, the Ultimate Supreme Leader, lied about being the mastermind of the Killing Game and that he was the leader of the cult bent on stopping the Gofer Project. He also lied about being the one who let Monokuma enter the spaceship, which effectively forced K1-B0 and the others to participate in the Killing School Semester. All of this was done in order to get everyone to fall into so much despair that they would not continue the Killing Game.

However, the true Mastermind, in order to get the remaining survivors at the time to continue the Killing Game, decided to connect everyone's memories of The Gofer Project to the story of Hope's Peak Academy. As a result, the true Mastermind prepared a Flashback Light that tricked the remaining participants into thinking that everyone, including those that had died, were actually students of the rebuilt Hope's Peak Academy. They also remembered that the ones behind The Gofer Project were Makoto Naegi, the headmaster of the rebuilt Hopes Peak Academy, and the Future Foundation. This Flashback light also revealed that the cult bent on stopping The Gofer Project were actually the Remnants of Despair, and that Kokichi was their leader. This lie filled everyone with the determination needed to stop the despair they were faced with.

In the Mastermind's rush however, they accidentally overlooked slight inconsistencies and plot holes when linking both stories together, such as "Ultimate Despair" only referring to Junko Enoshima, and that Class 78 was trapped by the Ultimate Despair when they had actually locked themselves within the school in order to shelter themselves from the tragedy outside.

Introduction
K1-B0 was among the first fourteen people gathered in the gymnasium before Kaede Akamatsu and Shuichi Saihara arrived. It is unknown how K1-B0 felt about the situation as he was never seen talking or interacting with anybody, nor is it known whether or not he actually had his memories of being a "connector" to the outside world at this time. Once the Monokuma Kubs arrived and revealed themselves from within their Exisals, they gave the sixteen participants their Ultimate wardrobe, and their first memory via the Flashback Light. K1-B0 and the other fifteen talentless students underwent the fabrication process, where all of their past memories and personalities were heavily fabricated. He also received the talent and title of Ultimate Robot. All of this was done for the sake of satisfying Danganronpa's audience from all over the world. After the fabrication process was completed, K1-B0 and the others entered the Ultimate Academy for Gifted Juveniles as totally different people, officially commencing the 53rd killing game season known as the Killing School Semester.

K1-B0 was later found in one of the classrooms on the first floor by Kaede and Shuichi, the Ultimate Detective, after deciding that they would explore and investigate the school together. Kokichi was also in that classroom, highly intrigued by the Ultimate Robot, constantly pestering him and asking him absurd question. K1-B0 was very agitated by this, trying to get away from him and politely asking Kokichi to "leave me alone". K1-B0 introduced himself to Kaede and Shuichi as the Ultimate Robot, stating that he was the finest creation of Professor Idabashi, the leading authority in the field of robotics. He told the duo that the professor raised him like his own child and that he had a maturing AI inside of him, though Kokichi found his backstory to be fairly unremarkable and become more disappointed from the Ultimate Robot's lack of exciting functions, like a rocket punch. Kaede thought to herself that they were both fairly strange individuals before continuing to explore with Shuichi.

K1-B0 would later gather with everyone else in the gymnasium after the Monokubs made their announcement. Everyone conversed with each other, wondering why all sixteen of them had been gathered together like this. Afterwards, the Monokubs and Monokuma, the Monokubs' father and the self-appointed headmaster of the Ultimate Academy for Gifted Juveniles, arrived and announced that they would be participating in a Killing Game, much to almost everyone's shock and horror. With that, the Killing School Semester had officially begun.

Attempting the Death Road of Despair
After Monokuma officially started the Killing Game, K1-B0 read the rules on his Monopad. A majority of the group wasn't sure what to do after reading these rules and began to panic and argue. Thanks to Kaede's motivational argument however, the panic died down and everyone seemed to become united. Afterwards, Gonta Gokuhara, the Ultimate Entomologist, then remembered that he found a manhole inside the boiler room behind the school building. K1-B0 along with everyone else immediately followed Gonta's lead, with hope of finding a way out. Upon discovering the manhole, K1-B0 volunteered to lift it, but his minimal power alone wasn't enough to lift it, much to everyone's disappointment. Nonetheless, he was impressed that Gonta could lift the manhole easily.

Descending the manhole, K1-B0 and the others found a tunnel leading outside of the academy. Though everyone thought that the tunnel probably ended up being a trap, they still had to test every single possibility in order to escape. However, K1-B0 and the others exhausted themselves both physically and mentally as they found that escaping through Death Road of Despair is next to impossible. Due to this, Kokichi revolted, saying that Kaede's repeated motivational speech is the source of the group's agony, added by some of her friends giving up on escaping the tunnel, K1-B0 included, the group's harmony came to a swift end. The tunnel ended up being a trap set by Monokuma and the Monokubs, much to everyone's dismay. K1-B0 headed to his assigned dorm room along with the others to get some rest, seeming fairly neutral on the issue, not taking any one side in particular.

The First and Additional Motive
The next day, K1-B0 and everyone gathered in the dining hall. Once Kaede showed up, the whole group began to think back to yesterday's events, but seemed to have consolidated slightly thanks to Kokichi's "kind lie". Afterwards, Monokuma came to the dining hall and announced the first motive, anyone who committed the first killing will graduate without holding a trial, effectively calling it a "First Blood Perk". Everyone was worried about what this would mean, aside from Kaito Momota, the Ultimate Astronaut, who became increasingly outraged with Monokuma for doing whatever he wanted and lunged at him. This caused the Monokubs to show up, showing no hesitation to punish Kaito with the Exisals for attempting violence against their father, effectively breaking the rules. The red Exisal charged at him, but accidentally ended up crushing Monokuma instead, supposedly destroying him. The Monokubs were incredibly saddened at the sudden demise of their father, stating that he had no spare and that he was one of a kind. Upon learning this, K1-B0 and everyone else's mood improved greatly, thinking the Killing Game to be over.

The next morning, K1-B0 was with everyone else in the dining hall once again, happy that the Killing Game had supposedly ended. However, it didn't take long for Monokuma to show up yet again, much to the dismay of the rest of the students, but to the joy of the Monokubs. Monokuma goes on to reveal the additional motive, that if a murder did not occur within two days by noon, everyone who was forced to participate would be killed. This motive caused a majority of the group to become too depressed to stay united and leave the dining hall, KI-B0 included.

K1-B0 didn't do anything notable during the time limit, even on the final day as the time limit was getting close to its end, he remained alone in his room. However, as soon as the body discovery announcement played and told everyone to go to the library, K1-B0 immediately rushed over there. He was among the last group of people to enter the library along with the people in the dining hall, Ryoma Hoshi, the Ultimate Tennis Pro, and Kokichi. There, they found Rantaro Amami, the Ultimate ??? dead on the ground in the back of the library. Everyone was shocked and baffled as to how and why Rantaro was killed as the investigation began.

The First Investigation and Trial
During Kaede and Shuichi's investigation, they began gathering information from everyone, asking them of their alibi's. K1-B0 partnered up with Korekiyo Shinguji, the Ultimate Anthropologist, to investigate the lookout classroom that Kaede and Shuichi used. When K1-B0 was asked about his alibi, he was unable to find the right words due to not actually having a proper alibi. Kaede found that suspicious that he was in his room the whole time, but reassured K1-B0 that him not having a proper alibi doesn't automatically make him the killer.

During the class trial itself, K1-B0 did not contribute to the discussion in an overly significant matter, but he did defend Shuichi when he was being accused of killing Rantaro due to not mentioning the camera intervals beforehand. He later listened to him point out Kaede as the killer, then watched as she was killed by Monokuma. K1-B0 did not seem to think ill of her, still viewing her as a good person for wanting to save everybody. He was left very frigthened with how she very gruesomely died. He later headed back to his dorm room along with everyone else, leaving the trial grounds.

Exploring the Rest of the Academy
The morning of the next day, K1-B0 along with everyone else would gather in the dining hall once again and have a normal, but forced conversation to try and make themselves not think about the horrible events that transpired yesterday. Afterwards, the Monokubs showed up and handed out four random items that the students could use to unlock more areas in the academy.

One of the areas that would become unlocked was the pool. K1-B0, Shuichi, and Tenko Chabashira, the Ultimate Aikido Master, were the first ones to investigate the area. Upon seeing the resort-like pool, Tenko became excited and stated that she had always dreamed of swimming in a pool like a famous celebrity, except for the fact that she didn't know how to swim. K1-B0 however, said that if he tried to swim he'd probably end up sinking. Tenko then wondered if K1-B0 was a boy or a girl due to technically not having a real gender. K1-B0 said that it was a good question and that he'd never thought about it before, but went with male pronouns simply because that was what he had always gone with.

Angie eventually told K1-B0 and everyone else to meet in the gymnasium, seemingly failing in discovering anything about the conspicuous flashlight that she and Shuichi had discovered earlier. After everyone had gathered, Monokuma appeared and told everyone that it was a Flashback Light and that it had the ability to restore lost memories before leaving and letting the students decide what to do with it. Although everyone was skeptical at first, they eventually gave in and used it, allowing everyone, K1-B0 included, to remember that they had been on the run from the "Ultimate Hunt". Though they could not remember the exact details and circumstances behind it, just that they had been on the run.

In a bonus scene in Chapter 2, K1-B0, Shuichi, Angie Yonaga, the Ultimate Artist, Himiko Yumeno, the Ultimate Magician, and Kirumi Tojo, the Ultimate Maid, joined Tenko for her "celebrity-like vacation" in the pool area, although K1-B0 seemed more interested in the parasol than he did anything else.

The Motive Videos
During that same night, the Monokubs prepared the second motive, distributing various motive videos at random while the students slept. The next morning, K1-B0 joined everyone in the dining hall in order to discuss what to do with the motive videos. Despite Ryoma suggesting that they exchange them, wanting to see who could be the most important person in his life, everyone rejected the idea, afraid that it would cause another murder to happen, much to his annoyance. K1-B0 agreed with the majority, logically thinking that a killing would be less likely to happen if they did not watch their videos.

Gonta's Insect Meet and Greet
The next day, unbeknownst to K1-B0, Gonta, thanks to Kokichi's lies, believed that everyone hated bugs and began kidnapping various students into his Research Lab in order to get them to like bugs. In reality, Kokichi simply wanted to get everyone to watch their motive videos in order make the Killing Game "more interesting". K1-B0 would be among the first students that Gonta detained. Not long after, Shuichi, Himiko, and Angie were also brought into Gonta's Research Lab, and the Insect Meet and Greet began. Everyone panicked as insects began to buzz about and wreck havoc. Even thought K1-B0 was a robot, he still had a horrified expression on his face as the insects harassed him and the other students all throughout the lab. Once Kokichi had returned with everyone's motive videos, K1-B0 decided that he had had enough and made use of his recording function in order to convince Gonta that The Ultimate Supreme Leader had tricked him, much to the former's anger. With that, K1-B0 and everyone else barring Gonta and Kokichi took back their motive videos before immediately leaving Gonta's lab, then heading to bed.

The Amazing Himiko's Magic Show
The very next morning, K1-B0 attended Angie and Himiko's magic show along with everyone else from Gonta's Insect Meet and Great, bar Kokichi. Angie explained the details of Himiko's trick before the Ultimate Magician jumped into the tank, having only a single minute to escape the water tank before it would fill with piranhas. Angie closed the curtains, but everyone grew increasingly worried as the timer continued to count down and Himiko had yet to come out. Gonta couldn't take it anymore and stormed the stage, wanting to save Himiko before the piranha's would fill the tank, much to Angie's disappointment. Once the timer ran out, the piranha's dropped into the tank along with some other large object, though Himiko had yet to come out of the tank. Tenko begged Angie to open the curtains, a plea that she promptly responded to by revealing the tank, however, no one was prepared for what they were about to see. Ryoma's lifeless, handcuffed body drifted within the tank, only having a couple seconds before the piranha's stripped the flesh from his bone, leaving nothing more than a skeleton, the handcuffs, and his belongings behind. With that, the second investigation had begun.

After the body discovery announcement played, the remaining students gathered in the gym. Kokichi playfully urged Gonta to throw K1-B0 against the tank because it would take too long to drain by hand. Tenko helped Gonta use the Ultimate Robot like a battering ram and shattered the tank, flooding the gym with piranha infested, blood red water. K1-B0 would gather Ryoma's body and belongings in one place afterwards, seeming dejected that he was used as a mere object.

The Second Class Trial
During the second Class Trial, K1-B0 called out the slip-up Monosuke accidently revealed when he said about the last time about standing on the window sill, saying that it's possible the culprit asked him in order to secretly confirm their murder plan, which caused Monosuke to shout in agitation, thus providing the students this useful ciritical information. Shuichi was able to pin Kirumi as the culprit of Ryoma's murder. They also figured out the distance between both windows in the pool area thanks to K1-B0. After listening to Kirumi's motivations for killing and seeing her try to escape her execution, K1-B0 and everyone else all came to the unanimous conclusion that the motive videos were far more dangerous than originally believed if they had the ability to make Kirumi go that far. As a result, everyone kept the motive videos but did not watch them.

K1-B0's Maintenance
The next morning, at Kokichi's request after unveiling Maki's true talent the night prior, K1-B0 along with everyone else barring Maki paid a visit to the "Ultimate Child Caregiver's Research Lab" only to discover various weapons all throughout the lab, proving that Maki was in fact the Ultimate Assassin, not a child caregiver. Everyone became worried at this, fearing that the talent of a killer may be a threat to their own survival. Kaito however, reassured everyone and said that he would take care of Maki. Afterwards, the Monokubs showed up, usurped their father as headmaster, and passed out more items for the students to unlock new areas within the academy.

While everyone else was busy searching the new areas of the academy, Miu dragged K1-B0 into her Research Lab in order to "perform maintenance" on him. Miu was very interested in the Ultimate Robot to a disturbing, erotic degree, much to his embarrassment. K1-B0 however, let her do whatever she pleased if it meant she would help him, saying that he had been neglecting his own needs ever since arriving at the Ultimate Academy. Miu told him to relax while she tended to him in "various ways". While it came off as odd initially, she was actually upgrading K1-B0 with flashlight function and a function that allows him to quite literally print out his memory. Both features would turn out to be highly useful in the next case and trial. K1-B0 also began to view Miu differently thanks to this, even going so far as to become jealous when she would spend time inspecting the computer room for the following days.

Later on, K1-B0 would gather with everyone else in the dining hall in order to inspect the new Flashback Light that Shuichi found. Upon using it, everyone remembered what seemed to be their own funeral, much to the student's confusion. Kaito reassured everyone that there's no way the funeral could be real considering they were all still here and alive. His small speech seemed to work, as everyone perked back up, enjoyed a small meal, then headed back to their dorms.

Angie's Student Council
That same night, Angie went to talk with K1-B0, Himiko, Tenko, and Tsumugi in hopes of converting them all to her ideology and create a Student Council with the sole intent of ending the Killing Game while also throwing away their own desire to leave the academy. All four of them were "brainwashed" by Angie and became dependent on Atua.

The now-converted K1-B0 gathered with everyone in the gymnasium the very next morning at the Monokubs request. The participants were presented with the third motive, the Necronomicon, and were told that they would be able to bring back someone who had died already as a transfer student. This motive baffled the students, saying that there's no way the dead could come back to life. However, Angie seemed to embrace the motive, saying the "corpses" so far may have just been very accurate imitations to make the real people seem dead. Some of the students argued that there's no way that's possible, but K1-B0 seemed intent on listening to what Angie had to say. He then listened to Gonta say that more letters were added to the rock in the courtyard, deducing that perhaps the four people who had died are actually alive and wrote that message. Angie praised Gonta and, like K1-B0 before him, pulled him into a hug. She instilled hers and Atua's authority into him by reassuring him that he's not alone and that Atua is like a gentle grandmother that always keeps him safe, effectively playing off of Gonta's desire for a motherly figure.

Angie then said that Gonta should join the student council, wanting to make Gonta feel needed. Tsumugi, and Himiko both requited this feeling. As a result, the Ultimate Entomologist did not hesitate for even a second if it meant he could be useful to everyone and joined Angie's group. Shuichi however, was confused as to what Angie meant by "student council", but K1-B0 replied by saying that Angie summoned himself, Tsumugi, Himiko, and Tenko last night in order to discuss how to eradicate the Killing Game and ended up forming the "Ultimate Academy Student Council" with Angie as their president. The "brainwashed" members listen to Angie completely and without question, stating that her will is Atua's will and as a result, she cannot be wrong. Angie took the Necronomicon and told everyone else to "leave it to the student council".

In reality however, Angie trying to unify the group with her student council only ended up causing discord between the student council and the non-student council members, such as during that same night when the student council ridiculed Maki for being out at nighttime. The very next morning, the two split parties came into conflict yet again after finding out that the student council had blocked off the manhole in the boiler room with a large rock. Angie even goes as far as to destroy a Flashback Light from the Monokubs, wanting to quell any desire to leave no matter the cost. K1-B0 and the others supported her one-hundred percent despite their extreme methods, having no malicious intent for the group, just wanting to stop another killing from happening by any means necessary.

The Third Investigation and Trial
The very next day, Angie's body was discovered in her own lab by Shuichi, Maki, and Tenko. After the body discovery announcement played, K1-B0 rushed in with everyone else and found their student council president deceased. He mourned her death along with the other student council members as the investigation began. Korekiyo suggested that they perform a seance to commune with Angie's spirit, a suggestion that K1-B0, Himiko, Kokichi, and Tenko agreed to, completely unaware that the Ultimate Anthropologist had sinister ulterior motives. However, later during the investigation, the others who helped with the seance decided that because of the fact K1-B0 was a robot, he would be unsuitable for the ritual. As a result, Shuichi took his place and K1-B0 left the room dejected. He would end up heading back to the seance room later on however after another body discovery announcement played only to find Tenko dead as well. Everyone was baffled at there being a second victim, but had to continue their investigation regardless. The room however, was too dark to investigate everything properly. Seeing this, K1-B0 made use of his new flashlight function that Miu installed, illuminating the entire room in a bright light.

During the third trial itself, K1-B0's new function that allowed him to dispense a printout of his own memory would turn out to be a valuable asset, as it allowed him to print out his own memory of seeing the magic circle before it was trampled over and ruined. Seeing this, Shuichi was able to see through Korekiyo's lie and pin him as the culprit of Tenko's murder. Korekiyo accepted the accusation wholeheartedly, claiming that Tenko's death was meaningless and that they had to find the culprit who killed Angie. His confession made many of the students emotional and quick to act, wanting to rush to the vote, but K1-B0 was among those who thought it best to hold off until they've fully solved Angie's murder. In the end, Korekiyo was pinned as the culprit of both murders thanks to the piece of bloody duct tape and the floorboard with dried blood on it. K1-B0 was shocked and baffled at Korekiyo's irrational motivations but then watched with the others as he was executed by Monokuma. Due to everything that had happened, K1-B0 and the other remaining student council members all concluded that there ultimately was no god watching over them in this academy and agreed to work together with everyone else from now on, effectively disbanding Angie's student council.

Later, when everyone headed back to their room after Himiko had tired herself out from crying too much, Kokichi poked fun at the Ultimate Robot yet again, asking if "robots need to leak their oils too". K1-B0 irritatingly responded that he himself does not use oil as his fuel source, as he had stated to the Ultimate Supreme Leader many times already.

K1-B0's Research Lab
The very next morning following the third class trial, K1-B0 gathered with everyone in the dining hall yet again. The group became disheartened to see how many people they had lost up until now. Monokuma then showed up along with his two remaining Kubs to hand out the next set of random items to unlock more areas with, along with a card key that, according to Monophanie, would be the next motive, though Kokichi stole it and ran off. K1-B0 would search the academy with everyone else for new areas to explore.

One of the new areas that became unlocked would be the Ultimate Robot's Research Lab, which connected to Miu's Research Lab. K1-B0 however, was more disappointed with the lab than anything. He claimed that he detested the sci-fi feel and wished for a more Japanese theme and that he preferred Japanese foods as well despite the fact that he couldn't even eat food due to being a robot. Shuichi also found his choice of preference odd and contradictory, but kept that fact to himself as to not irritate him.

K1-B0 later regathered with everyone in the dining hall to investigate yet another Flashback Light. Once used on themselves, everyone remembered the meteorites that impacted the Earth and that it was described as being very similar to the meteor impact that wiped out the dinosaurs millions of years ago. They also remembered basic details of the cult bent on stopping the Gofer Project saying that mankind deserved damnation, and the Gofer Project itself. K1-B0 and the others were worried about the meteorites, but Kaito as per usual, reassured everyone, saying that the meteorites had to have died down if the sky outside was fine.

Neo World Program
A couple days later, Miu would gather everyone, K1-B0 included, in the computer room on the fourth floor. She explained to everyone how she had been working on it for the past few days or so and reprogrammed it into a "world without Monokuma or the killing game". In reality however, she was actually plotting her own murder plan in order to escape. With Miu's persuasion, K1-B0 and the others agreed to head into the virtual world after hearing about a supposed secret of the outside world from Monokuma. The amnesiac Monotaro also began to view Miu and K1-B0 as his parents. While Miu was more than happy to accept the claim, K1-B0 was less than thrilled.

K1-B0 sat down in his chair and put the cords in his own headset, making sure to listen to Miu's explanation. Once K1-B0 logged in with the others, he was disappointed by the fact that he still had a robot body even as an avatar, secretly hoping for more. K1-B0 was punched by Kokichi as soon as he logged in in order to see if they all could still pain, which Miu confirmed as well once she logged in. K1-B0 listened to her explain more aspects about the virtual world such as their avatars senses being connected to their real bodies, objects are unbreakable, and showed them all the map of the world. With this knowledge obtained, everyone then headed to the chapel, making use of a signboard to cross the river. After reaching the chapel, everyone decided to explore the virtual world in order to find the supposed secret Monokuma was referring to. K1-B0 remained with Maki, Himiko, and Miu at the chapel in order to investigate, but Miu followed the other group and threw the signboard in the river to ensure that both groups would remain separate. As time passed and everyone continued to explore and investigate, K1-B0 along with all the others in the virtual world heard a loud crashing sound. Upon leaving the chapel to investigate with Maki and Himiko, they found Miu's avatar unconscious besides the chapel. The trio became increasingly worried and attempted to reunite with the other group only to find the signboard used as a bridge gone thanks to none other than the Ultimate Inventor herself. They were still able to speak with the group exploring the mansion across the river and tell them about what had happened, worrying them as well. The other group was able to find the signboard used as a bridge in the river and place it down as a bridge once again, allowing everyone to regather and log out to make sure that Miu was okay. However, K1-B0 and everyone else were horrified and dumbfounded to find Miu dead in her own chair, dying from the shock of having her avatar killed. K1-B0 was especially saddened by her death due to everything that she had done for him, claiming that although she was brash and spirited, she wasn't a bad person. And he wished he should cry, but Miu hasn't give him a crying function. With that, the investigation began for a fourth time at the Ultimate Academy for Gifted Juveniles..

The Fourth Investigation and Class Trial
During the investigation, K1-B0 continued to ponder just what the secret of the outside world that Monokuma wanted them to find actually was, as nobody found anything suspicious. However, Kokichi jokingly teases him for caring more about the investigation, greatly upsetting K1-B0.

During the class trial, when Gonta was being pinned as the culprit by Kokichi and Shuichi wanted to explore the possibility, K1-B0 was the only other student to stand by them, choosing to think about the situation logically rather than letting emotion overcome him like all the other students were. In the end, K1-B0, Kokichi, and Shuichi turned out to be right about Gonta being the culprit but did not view him as a bad person, saying that it wasn't his fault and that Kokichi must have tricked him. In the end, K1-B0 watched as the kindhearted Gonta was executed by Monokuma; and he was also left very horrified after witnessing what Monokuma has done to Monophanie and Monotaro after they gruesomely died during the execution and by Momokuma's claims that they've been "ignoring" him. After Kokichi supposedly stated that he enjoyed watching them all suffer, K1-B0 like everyone else viewed him as an outcast and ignored him, being more worried about Kaito who began coughing up an unhealthy amount of blood. Kaito stubbornly reassured everyone that he was fine before leaving the trial grounds. K1-B0 would also leave to get some rest along with all the others.

Down to the Final Few
The very next morning, K1-B0 gathered with everyone else in the dining hall. Everyone else was obviously still worried about Kaito, but he once again tried to reassure them that he was fine and they all ate breakfast together. After eating, Kaito wondered just where Kokichi had gone off to after his monologue yesterday. K1-B0 and the others became tense and frightened at the mere mention of the Ultimate Supreme Leader, but everyone said that no one had seen him since yesterday. Monokuma showed up after not too long and passed out the last set of items to unlock new areas in the academy with.

One of the new areas that became unlocked was the Cyber Courtyard and the Exisal hangar. K1-B0 was the only student to investigate it, but was eventually joined by Shuichi after he finished investigating the Ultimate Astronaut's Research Lab with all the others. K1-B0 and Shuichi were both concerned about the Exisals within the hangar, but Monokuma showed up and told the duo that they were no longer a threat to them due to all the Monokubs having been destroyed. K1-B0 and Shuichi also investigated the press machine and saw that it had a safety mechanism that made it stop if it detected a living organism. K1-B0 and Shuichi both decided to test the press machine, with K1-B0 lying down in it. Shuichi activated the press machine and it slowly began to lower. K1-B0, seeing that Shuichi was not going to stop it on his own, rolled out of it at the very last second to avoid being crushed. Shuichi was relieved that he was okay, but K1-B0 asked him why he did not press the forced stop button. Regardless however, the press did not stop due to the fact that K1-B0 did not count as a "living" organism, much to the Ultimate Robot's dismay.

After everyone had uncovered all the new areas, K1-B0 gathered with everyone in the dining hall at Tsumugi's request, but not to discuss a Flashback Light. Instead, she informed everyone that the message in the courtyard had been completed, “This world is mine. Kokichi Oma”. Kaito just wrote it off as Kokichi’s prank, not taking the final message seriously whatsoever. Everyone else seemed to agree with him, though wondered just where Kokichi had gone to and wondered if he took the Flashback Light seeing that none of the others had found it yet.

Clearing the Death Road of Despair
The next day, after Kaito realized that he didn’t have much time left due to his illness, declared to K1-B0 and the others that they were all going to fight Monokuma the very next morning. He wanted to make good on his promise that he'd get everyone out alive, but needed their help if they were all going to get out of here. He said that now was their chance to finally fight back because the Monokubs were gone, meaning the Exisals would no longer be a threat to them. K1-B0 and the others were was still unsure however due to the academy being completely under Monokuma's control and having numerous spares. Hearing this, Kaito asked them all if they were fine with the way things are now and that if they weren’t, then they had to fight. Eventually, as more and more people became determined by Kaito’s speech, K1-B0 also agreed. Everyone prepared mentally to fight Monokuma that same night.

As planned, K1-B0 and everyone else gathered in the gymnasium at nighttime, with Kaito bringing a vast assortment of weapons from Maki’s Research Lab. While everyone was preparing for battle however, Kokichi suddenly appeared as well and brought with him Miu's memento, the Electrohammers. He offered them to his classmates claiming that he wanted to end the Killing Game as well, but Maki was tired of his deceptive nature and threatened to strangle him once again, asking him just what he was scheming. Maki was eventually stopped by Kaito and the others, dropping Kokichi on the floor. The Ultimate Supreme Leader told everyone that he wouldn't interfere with them any longer before leaving the gym, along with Miu's memento for them to use. K1-B0 and the others were still skeptical, thinking that the hammers might have been trapped, but still had to explore every possibility. With Miu’s memento in hand, everyone headed to the Death Road of Despair. As they stood before the tunnel, K1-B0 and the others remarked that they would finally be able to fulfill Kaede’s wish and escape this Killing Game, making everyone even more determined. With that determination fueling them forward, they headed into the tunnel.

After crossing the Death Road of Despair with Miu’s electrohammers, they came across a large metal hatch which they opened up and discovered the apparent state of the outside world, ruined and destroyed by meteorites, shocking everyone. K1-B0 and the others all became unable to breathe and lost consciousness not long after. An unprecedented time afterwards, the hatch closed and everyone woke up. Kokichi appeared and congratulated everyone for discovering the truth of the outside world. He revealed everything to them, that the world was in ruins, and that they were secretly on a giant spaceship that acted as an ark for the last sixteen survivors of humanity, or rather last "seven" survivors of humanity. Afterwards, Kokichi proclaimed himself as the leader of the cult bent on stopping The Gofer Project and the one who let Monokuma into the ark, effectively declaring himself as the Mastermind of the Killing School Semester. Everyone was skeptical at first until Kokichi used a universal remote control to make the Exisals do his bidding, further convincing the remaining survivors that he was in fact the Mastermind. Kaito once again becomes outraged with Kokichi and attempted to punch him yet again. However, Kokichi easily incapacitates the Ultimate Astronaut using the Exisals. Maki attempts to attack him as well, but is stopped by Shuichi. Afterwards, Kokichi requests Shuichi to give him back the Exisal hangar's alarm remote back, a request that he reluctantly complies to for Kaito's own safety. Kokichi declared that everyone was free to do whatever they pleased before leaving them all in a state of despair and taking Kaito hostage in the Exisal hangar. K1-B0 and everyone else were left in utter despair at this revelation, unsure of what to do now that everything had been revealed and turned out to be meaningless.

Hope Renewed
Two days later, Maki would attempted to gather everyone barring Kaito and Kokichi in the dining hall to inspect a newly discovered Flashback Light. Everyone aside from Maki wasn't sure what the point of examining the Flashback Light even was anymore thanks to everything already having been revealed, but decided that they may as well use it just to not leave any stones unturned. Upon using it, K1-B0 and everyone else remembered that they were all students of Hope's Peak Academy, that the cult trying to stop The Gofer Project was actually the Remnants of Despair, and that Kokichi was their leader. With this memory perfectly etched into their memories, they all vowed to save Kaito, stop Kokichi, and end the Killing Game once and for all. More determined than ever before, everyone planned to storm the Exisal hangar the very next day after charging their Electrohammers.

Later that same day however, K1-B0 would witness Himiko from his own Lab, carrying a large black case into the Cyber Courtyard. He wasn't sure what she was holding or what she was doing, but found it oddly suspicious nonetheless. As it turns out, she was bringing Kaito a crossbow and a single arrow at his request. K1-B0's witness testimony would turn out to be a valuable clue during the upcoming Class Trial.

The very next day, with their Electrohammers fully charged, K1-B0 and the others began their assault on the Exisal hangar, using an Electrobomb that Maki had snatched from Kokichi two days earlier to open the shutter. As soon as they entered the hangar itself however, they were all shocked to find a body crushed beyond recognition underneath the hydraulic press, the only clue as to who the victim could be being Kaito's sleeve hanging out from underneath it while Kokichi had seemingly gone missing. Everyone is horrified at the thought of having lost Kaito as the investigation begins.

During the investigation, K1-B0 searched outside of the hangar due to not feeling well from the effects of the Electrobomb. Although everyone thought that it was probably because he was a robot, he claimed that that was a robophobic remark and that it was simply an "allergic reaction". Later on, he would investigate the bathroom inside the hangar. More specifically, he investigated the toilet, reaching down the drain to discover Kokichi's clothes flushed. He quickly informed Shuichi of his discovery after he had finished investigating his own and Maki's Research Lab. He was quite stunned at K1-B0's discovery, but found it awkward to shake his hand after having reached into a toiler to find this evidence. As a result, they both decided to wash their hands and leave the bathroom, the investigation officially ending not long after.

The Fifth Class Trial
During the Class Trial, K1-B0 along with everyone else were still confused about their current state of beginning a Class Trial with two missing people, but Monokuma reassured them that it's fine and that the one missing person is "on standby in the back". When that supposed missing person arrives riding an Exisal and supposedly pretended to be Kaito before "revealing" themselves as Kokichi, K1-B0, along with everyone else, believes that Kaito must have been the victim until later on in the trial, where the voice coming out of the Exisal changed to match Kaito's again. K1-B0 along with Himiko and Tsumugi believed that the victim could have been Kokichi and that the one riding the Exisal was Kaito. Although Shuichi and Maki thought that they disproved this claim, it is later revealed that K1-B0 was originally right near the end of the trial and that the one inside the Exisal was in fact Kaito carrying on Kokichi's will.

K1-B0, along with everyone else, was rendered depressed, stunned and silenced at the fact that Kaito ended up being the culprit of Kokichi's murder. However, he reassured everyone to smile, send him off in style, and that he won't accept their tears before proudly accepting his execution, but choosing to die on his own terms and not Monokuma's. During his execution, however, a bit of rubble was kicked up, knocking off K1-B0's "connector" to the outside world, making him unable him to hear the audience's voice, causing him to malfunction.

While everyone else gathered in the courtyard for training, intent on carrying on Kaito's will, K1-B0 decided to go to his lab and equip the jet pack and laser gun that were in there. Although he detested such technology, he decided that he could not longer stick to idealism and as such, resolved himself to destroy The Ultimate Academy for Gifted Juveniles, believing it to be seeped in Despair.

K1-B0's Rampage
The now upgraded K1-B0 began his relentless assault, attacking the school indiscriminately, flying about and shooting lasers all over. Everyone else were shocked and frightened to discover the academy coming under fire from the Ultimate Robot. The group ran to the front of the school to try and get K1-B0's attention. He eventually hovered down towards them, stopping his assault, and asked him what they wanted and to keep this brief. When asked, K1-B0 said that no matter where they go, Despair will be right around the corner. As a result, he was determined to destroy the school even if it meant that he himself and everyone else would die. Shuichi was eventually able to turn his way of thinking around, but only until dawn. K1-B0 threatened everyone that if they could not find the truth behind this Killing Game before dawn breaks, he will continue his destruction of the academy. Monokuma and the rebuilt Monokubs in their respective Exisals eventually showed up to try and stop his assault, declaring that the Killing Game cannot be ended. With that, the others ran into the school for cover while K1-B0 tried to hold the Exisals off until dawn.

Despite K1-B0's extreme actions however, he still reassured everyone that he was not their enemy, as he still aided the students in any way he could, such as showing up to distract other wandering Exisals, and blowing open locked rooms such as Rantaro's Research Lab and the hidden room in the library. All of this ensured that the remaining survivors would be able to discover the truth behind this Killing Game. He also told Shuichi of something odd he had seen on the second floor classroom and advised him to investigate. What K1-B0 saw ended up being a machine to create Flashback Lights with, another valuable clue.

After finding the entire truth, Shuichi headed out to the courtyard to stop K1-B0's and Monokuma's fighting, telling both groups that they were going to hold a Class Trial. K1-B0 was skeptical at this, but Shuichi reassured him that this was a Class Trial that would end the Killing Game. Everyone else also showed up, equally as confused about what was going on. Monokuma however, agreed to Shuichi's terms but only on the condition that they would be responsible for this Class Trial if it ended up being disappointing. K1-B0 however, was told by Monokuma that he had to take off his armaments before being allowed into the trial grounds. While the Ultimate Robot was reluctant to do so, Shuichi reassured him that he was indeed trying to end the Killing Game. Hearing this, K1-B0 headed to his lab with the Monokubs to remove his equipment while also having his antenna fixed, allowing him to hear his inner voice once again.

K1-B0 later rejoined everyone at the Shrine of Judgement, feeling extremely guilty for his actions as he was now able to hear his inner voice once again. Shuichi found the "inner voice" he had been constantly mentioning odd and noticed that his hair resembled an antenna, he made sure to keep this deduction in mind for later. K1-B0 also noticed the bugvac that Maki was carrying and asked to inspect it. When he did, he used his zoom-in function to finally discover the "tiny insects" that Gonta was always seeing, the Nanokumas. K1-B0 threatened to crush the tiny Monokuma units if they did not explain to the survivors what their purpose was. The Nanokumas agreed to the Ultimate Robot's terms and told him that they were a part of the Monokubs and were the surveillance cameras of the entire campus, acting as a swarm and sending any footage they receive wirelessly to Motherkuma. With this final clue in hand, everyone headed to the trial grounds one last time with every intent on ending the Killing Game once and for all.

The Final Class Trial
K1-B0, along with fellow survivors Himiko, Tsumugi, and Maki, at Shuichi's recommendation, decided to re-open Rantaro's case after discovering new truths related to his murder. Once Shuichi revealed Rantaro's talent as the Ultimate Survivor, and proved that Kaede did in fact not murder him and was executed unjustly, he realized that the Mastermind has to be one of them. In order to find out who, Shuichi recommended that they all double-check everyone's alibis during Rantaro's murder, which finally allowed Shuichi to hone in on Tsumugi as the true culprit and Mastermind of the Killing School Semester.

K1-B0 along with the other survivors were confused and shocked that the Ultimate Cosplayer could have gone through with such a plan while she denies the claim vehemently. Shuichi, however, made it very clear that Tsumugi was the only person who could have murdered Rantaro by using the hidden passageway in the girls' bathroom, which led into the hidden room that connected to the library. She attempted to pin the blame on K1-B0 since he was not present for when they interacted with Motherkuma, but Shuichi is quick to call her out on not giving the command of "birth" which would have triggered Motherkuma's voice recognition software and created another Monokuma. Realizing that she had been cornered, Tsumugi finally dropped her act and revealed herself as "Junko Enoshima the 53rd".

Tsumugi, now cosplaying as Junko, went on to state that she simply wanted to reproduce her own Killing Game and that there was nobody watching. Shuichi however, did not believe this claim due to their contradicting memories, as well as the facts regarding Kokichi and Rantaro that also conflicted with their memories of the Hope's Peak Academy Saga. As a result, Shuichi was able to determine that everyone's memories of being students at Hope's Peak Academy, The Gofer Project, and shouldering their friends and families burdens as mankind's last hope, was all a false memory planted into their brains by the Flashback Light. Tsumugi then revealed that everything they remembered about attending Hope's Peak Academy and the outside world being destroyed was a lie and that the Flashback Lights were actually tools to implant new memories, not tools to help you remember. What the participants remembered about Kokichi being a part of the Remnants of Despair was a lie as well, much to everyone's shock.

In reality, the circumstances behind their Killing Game were far more cruel. After proving her talent fully as the Ultimate Cosplayer by cosplaying as the participants of the Killing School Life and the Killing School Trip, Tsumugi revealed that everything that took place in the Hope's Peak Academy Saga was nothing more than fictional events from a very popular anime and video game franchise known as Danganronpa. She also revealed that their entire Killing Game had been broadcast to a very peaceful world that were completely obsessed with Killing Games, essentially revealing that everything they've been through as a reality-TV show and "Ultimate Real Fiction". She told them all that she herself was a part of Team Danganronpa, a company that makes the "finest killing entertainment" and that everyone loves their work.

While K1-B0 along with the other survivors were quick to oppose Tsumugi and Monokuma, they both revealed that the participants of the Killing School Semester are also "fictional characters", whose memory, personality, feelings, and talent were all fabricated by the Flashback Lights in order to provide exciting characters for the Killing Game. To back up her claim, Tsumugi showed Shuichi's, Kaede's, and Kaito's supposed audition videos for the Killing Game, showing that they were all very twisted or outright depressed people that, like the audience watching, were obsessed with Danganronpa to the point where they willingly participated in the Killing Game. Everyone became shocked at this sudden revelation and subsequently fell into despair, unsure of what to do now that everything so far had been revealed to be lies.

Hope or Despair
K1-B0 however reassured everyone not to lose hope, stating that that was what his "inner voice" was telling him and that if this was the "Ultimate Real Fiction", then not all of it could be fictional and that there must be something they could do. Tsumugi corrected him and said that the voice he had been hearing this entire time was actually the voice of the people watching this Killing Game, an audience survey. She continued to state that he was nothing more than an interactive communication device and camera for the viewers to interact with and participate in the game themselves. Despite this however, K1-B0 refused to give up on hope and stated that the people in the outside world don't want despair, earning him the title of Ultimate Hope Robot (超高校級の「希望 ロボット」chō kōkō kyū no “kibō robotto” lit. Super High School Level Hope Robot). Tsumugi, meanwhile refused to give up on despair and stated that a world that enjoys killings could not possibly desire Hope. In true Danganronpa fashion, they decided to settle this with one final, special vote where K1-B0 represented Hope and Tsumugi represented Despair. K1-B0 was willing to sacrifice himself if it means his friends could survive, hearing this, Maki also decided that she would willing sacrifice herself along with K1-B0 if it means that Shuichi and Himiko could live despite the fact that there was supposedly nothing left for them in the outside world.

Shuichi however, saw through the charade and cut in, saying that neither choice was correct and that choosing hope would do nothing but cause the Killing Game to continue, which he and K1-B0 were able to deduce thanks to the late Rantaro's circumstances. Because of this, Shuichi decided to stop playing along and abandoned his vote, hoping to end Danganronpa once and for all by willingly sacrificing his own life, much to Tsumugi's and Monokuma's chagrin. This caused K1-B0 to question his feelings of wanting hope and doubt the inner voice that had guided him all this time. In the end, K1-B0 decided that even if his inner voice told him not to give up on hope, that he could not trust it if it demanded more tragedy from them, angering Tsumugi and the audience. Eventually, Shuichi convinced everyone else to abandon their vote as well but K1-B0, in a last ditch effort to keep Danganronpa going, was taken over by the audience. Seeing this, Tsumugi laughed, proud to show that the audience did not wish for Danganronpa to end and explained that they supposedly deleted K1-B0's personality that kept getting in the way. K1-B0 was able to take brief control again and told his fellow survivors that their choice is not the wrong one and that they can indeed change the world through him before the audience took him over again. Despite Tsumugi telling the others that what they're doing is pointless, Shuichi refused to give up, still exclaiming that he will end Danganronpa and that their lives are not just show-things for their amusement.

K1-B0's Fate
Confident that his voice reached the outside world through K1-B0, Shuichi and everyone else abandoned their vote. Tsumugi however, bent the rules one last time and abandoned her vote too, which she revealed after everyone else did. Shuichi, Maki, and Himiko are immediately confused and worried as to why she abandoned her vote as well. Tsumugi stated that if they're going to risk their lives to end Danganronpa, then she would risk her life to make it continue. Tsumugi was confident that Danganronpa would continue after abandoning her vote, meaning only K1-B0's vote would have any power as he was still being controlled by the outside world. She even went as far as to describe a new plot-line for him in the next Killing Game.

When Monokuma displayed the results of the final voting, Tsumugi was shocked to discover that no one had voted, not even K1-B0, proving that the audience did not want Danganronpa to continue. Tsumugi panicked and tried to make everyone reconsider, but it was no use as the monitors all turned off, the audience no longer showing any interest. Tsumugi, upon realizing that Danganronpa was indeed over and done with, promptly lost all of her hope in living as she denied a world without Danganronpa, but had not prepared a proper execution beforehand and as such, left it to K1-B0.

K1-B0 did not hesitate and proceeded to execute everything, killing Monokuma and Tsumugi, the latter of whom waved at the camera with a look of disappointment on her face before being flattened under rubble inadvertently caused by K1-B0, ending the Killing Game for good. After making sure that his fellow survivors were still alive, K1-B0 smiled, activated his self-destruct button, began flying towards the glass dome and exploded, promptly destroying the dome and allowing his friends to escape into the outside world.



Once the final execution had ended, the three remaining survivors, Shuichi, Maki, and Himiko, wondered why K1-B0 had let them live since he was acting on the will of the outside world. Shuichi concludes that it must have been the outside world's will to let them live since K1-B0 was acting on their will.

Creation and Development
K1-B0, along with Maki Harukawa and Kaito Momota, was one of the first new characters revealed for Danganronpa V3 in November 2015 and he was speculated as a possible main character. However, their names and talents weren't revealed until ten months later in September 2016.

Name
In the original Japanese, his name is written as キーボ but romanized "Ki-Bo", although the correct pronunciation for キーボ is actually "Kiibo", as "ー" is used in Japanese to denote a prolonged vowel. If his name's spelling is adjusted to actually be pronounced "Ki-Bo", it could be spelt as キボー (Kibō), which is a pun on the word 希望 (kibō) meaning hope.

In the English localization, the spelling of his name is changed to "K1-B0", a naming convention which is a reference to the names of robot characters in the franchise such as  and. Although he states his name is pronounced "K-One-B-Zero", K1-B0 prefers people to pronounce it "Keebo", maintaining the original Japanese "kibō" pun.

His name in the Chinese localization is "機望" (jīwàng), which sounds very similar to hope in Chinese, "希望" (xīwàng). It also carries another pun, with 機 (jī) meaning "machine" or "mechanism", relating to the fact that he is a robot.

Alternate Fates
In Danganronpa V3: Killing Harmony (Demo Version), K1-B0 was chased around in by Kokichi Oma in the storage room. He tried to protect himself from being touched by the Ultimate Supreme Leader. After Kaede Akamatsu and Makoto Naegi entered the room, K1-B0 introduced himself and told his backstory as Professor Idabashi's creation. He proudly said that despite being a robot, he is a normal high schooler.

Before the class trial start, K1-B0 found out that the stands were too few for eighteen people and Monokuma decided to get rid of two people. K1-B0 who was automatically voted out by Kokichi became flustered and asked not to decide something important all by himself. However, he eventually ended up becoming an observer alongside Rantaro Amami and didn't participate in the class trial until the end of the demo.

Appearance
K1-B0 is a robot, therefore having a fully mechanical body structurally engineered to, in shape, resemble a human being. His body is mostly made up of metallic, armored plating, not wearing actual clothing, but resembling a, a school uniform worn by male high school students. He has four glowing buttons that run from his chest to his stomach down the middle of his torso, a metallic left breast pocket, and something that resembles a belt around his waist, two red buttons attached.

As a robot, K1-B0 is considered sexless and lacks the means to have reproductive functions, but still appears masculine physically and has the voice of a teenaged boy. His face has very pale skin. His eyebrows press closely to his round, mechanical blue eyes, making it appear that his brows are a part of his eyes. Thick black lines run from around his eyes and down his cheeks to reach his chin. He can make his eyes glow a bright yellow or blue and emit light. He has a tongue, but it doesn't seem to have any other purpose than speaking, as he cannot actually eat food. He has white hair that is very sharp and swayed to the left, along with the very large on the top of his head.

K1-B0 possesses a very tall, round and metallic collar around his neck, his previous school's emblem on the left side of his collar. A thin strip of screen wraps all the way around it, displaying a constantly changing string of green text. A softer black material covers his neck entirely, but he is capable of moving it up to cover the lower half of his face to resemble a face mask. The collar is usually open in the middle, but is able to clip the two metallic parts together to protect the area of his neck entirely. He doesn't seem to have actual ears, but black, headphone shaped objects in the area around them. He can use his ears to take recordings and play them out loud.

Later, it is revealed that K1-B0's ahoge is an antenna that receives information from Team Danganronpa, which will take the form of an "inner voice" and persuade him to take certain actions, said actions being decided through viewers' surveys.

In the prologue, he wears the uniform of his original high school, including a student hat. It's a plain, black with white buttons buttoned down the middle and on his cuffs, and he wears black gloves. His uniform is a bit too small for him, his jacket described as "bulging as if it's about to burst" due to the robotic body underneath it. Still, he looks more human, lacking some of his more mechanical traits such as the black lines on his face and the black headphone shaped ears on the sides of his head.

Personality
K1-B0 is a polite and serious teenage robot, who has some trouble with human social interaction, and often comes across as unintentionally comical as a result. According to Kazutaka Kodaka, K1-B0 has both cute and cool characteristics, with him being socially awkward but serious. Nevertheless, K1-B0 takes pride in his form and often boasts about his wonderfulness and efficient functions, though the other students never seem to find them impressive much to his disappointment. His aim is to overcome being an ordinary robot and because of this, he may get offended if he is compared to much more simple machines. While generally well-mannered, he is quickly angered by any prejudice against robots and sometimes threatens to sue people who make "discriminatory remarks". He considers robots a minority group among humans and can get slightly paranoid about "robophobia", supposedly because of past experiences. However, ironically, he himself is shown acting condescending and perpetrating "robot-on-robot abuse" towards simpler machines such as the robots with Monokuma's likeness, considering them mere stuffed animals who are beneath him.

Since he is a maturing AI, K1-B0 learns and develops similarly to a human, making him an unique existence. While he has no heart nor brain, he uses his calculations to speak "as if he had a heart". Even still, he often can't read the mood around him and is oblivious to things, sometimes taking things very literally and occasionally acting insensitive. Due to being overly serious about certain topics and unable to understand sarcasm, he is an easy target for bullying and it's easy to make him heated up, and he is rather easy to read. According to Izuru Kamukura in the bonus mode Ultimate Talent Development Plan, K1-B0 has a tendency to rely on others in difficult situations, and he overall gets very nervous in bad situations. Furthermore, he feels a bit self-conscious about the fact that he cannot strengthen his body on his own like humans, and he needs help for maintenance and upgrades. Overall, he is a bit conscious about being unable to do some things humans can, causing him to act condescending towards humans at times and proclaim that he can do lots of things humans cannot. In Chapter 4, when the students enter the program world, K1-B0 appears disappointed and secretly wished he would have a human body. In Chapter 5, he is seen wondering his existence and being very interested in whether or not he is considered a person by the hydraulic press' safety function and Miu's Electrohammers, and even wants to test them despite the risk. In one scene, he is scared of the idea of a huge mecha suddenly appearing, not realizing the irony of it. He himself has also pointed out that he doesn't really like "sci-fi" things, even though his existence alone is quite sci-fi, and he would rather be more like other people instead of possessing things like rocket jets. He greatly loves Japanese culture, including Japanese food (though he can only look at it), kimonos and wind chimes. However, he also feels insecure about being too ordinary and not deserving his title as the Ultimate Robot, which is why he has a dream of becoming a pop star or doing some other type of work. For a short time, he even considers becoming a "tragic hero" figure in order to become more interesting, with a new tragic backstory and weapons, even though it's not something he would like. In general, he has a strong desire to be accepted and be like everyone else.

K1-B0 seems to understand most human emotions and many of their habits, though some of them only in theory, and he prefers to make decisions and actions based on logic. He claims that he works very hard every day to understand human emotions, and he's often quite hurt and saddened whenever the other students tell him that he wouldn't understand something because he is a robot. He tends to find abstract ideas frustrating and difficult, and sometimes has a hard time understanding why someone would do something that is very illogical. In general, he can get confused and a bit uncomfortable by his strange classmates, and sometimes reminds them to speak in a way he can understand. He can also get some habits a little wrong, like confusing the action of handholding and handshaking. Like a human, he blushes when he is feeling shy and feels awkward when talking about something inappropriate, though occasionally he may say inappropriate things without realizing it due to his naivety. For example, he considers nudity very shameful and embarrassing, but doesn't seem to see anything inappropriate in going to the bathroom, as he sometimes casually tells his classmates they're free to do that if they are close to a bathroom or even telling them they can do it right there even if they're in public surrounded by people, seemingly trying to be polite with this gesture. He can be very expressive with his body language since as a robot he can move his ahoge and some other parts according to his emotions. Being a robot, he is also very innocent when compared to most teenagers, and some situations make him very nervous and shy. In Chapter 3, he claims he is ticklish and it's implied that he might be able to feel pleasure similar to sexual pleasure when sensitive spots underneath his armor get touched. In general, he doesn't seem to have very much interest in sexual matters, considering it quite scandalous and claiming at one point that he would never expose Professor Idabashi's strong AI to pornography. He has also bashfully pointed out that there isn't much he can do about it anyway, since he lacks any reproductive functions. However, he secretly seems to have some interest in such subjects, as he once accidentally admitted this without thinking. When he is asked about his ability to fall in love, he says he doesn't know because he hasn't had any romantic feelings yet. In the bonus mode Love Across the Universe, it's eventually confirmed that he can fall in love and dreams of romance and intimacy. In the topic of romance, K1-B0 is shown to find the idea that robots should only date their own kind very offensive. When he does develop romantic feelings, he is shown to be very serious and surprisingly bold about the matter, assuming that you constantly have to do typical things couples do and be very dedicated in order to truly understand love. However, he is simultaneously very shy about the subject, as he gets very embarrassed, blushes a lot and stutters when he just asks to hold hands. He also seems to consider the maintenance Miu performs on his body very intimate and he is very embarrassed about it at first, especially if it's mentioned in front of others, as if it is a sexual relationship (though, it does resemble a one). While he doesn't speak to Miu in explicitly romantic manner, he does care about her a lot and even gets jealous of a computer.

Overall, K1-B0 appears to be quite well-meaning and kind, and he genuinely wishes to be friends with everyone (even considering Kokichi his friend during the bonus mode). He has mentioned multiple times that he wishes to make people smile and happy. He even likes comedy movies, because he enjoys the feeling of people having fun and wishes to become a robot who can make lots of people smile someday, like a comedy movie. He is also pacifistic and refuses to hurt humans, greatly respecting, and in general dislikes violence and weapons. He also dislikes certain action movies for the way they portray robots as evil and murderous killing machines, considering it robophobic since most robots are friendly to humans. During the bonus mode, when Shuichi suggests making their own movie, K1-B0 would like to make a drama about hero stuff, which would be popular with children. K1-B0 wants to be the fearless hero while Shuichi would be the innocent citizen he saves from a villain. In Chapter 4, he even has some empathy for those he dislikes, as shown despite his grudge against Monotaro, he feels regret for Monotaro and Monophanie dying a terribly disturbing way and is upset at Monokuma for unsympathetically killing them like that.

K1-B0 often serves as the butt of jokes and is rarely taken seriously by the other students, which isn't helped by his somewhat wimpy and oversensitive personality, but he gets increasingly confident throughout the game and begins to motivate others and talk about hope and defeating despair, especially after remembering Hope's Peak Academy. During Kaito's execution, he even leaps forward to protect his friends with his more durable body. Furthermore, with his logical way of thinking, he quite often makes correct arguments and points out important things, not letting feelings cloud his judgement. He is willing to approach even unpleasant topics, such as the possibility of Gonta being the murderer, for the sake of reaching a logical conclusion and he tends to stay calm and sensible whenever most other students get too emotional to argue properly. Some of this could be a result of his "inner voice"—voices inside his head that guide him in difficult situations. He decides to listen to them more firmly after hearing Angie Yonaga's talk about God, treating his inner voice as his God who gives him advice and cheers for him. When he's mocked for being a robot who believes in God, he says robots can do that. When his ahoge gets broken by Kaito's execution, the voices get silent, causing everything to get "too quiet" for him and forcing him to use his own logic. It's later revealed that his ahoge is actually an antenna that receives information from Team Danganronpa, which will take the form of an "inner voice" and persuade him to take certain actions, said actions being decided through viewers' surveys.

When forced to make his own decisions without the inner voice, K1-B0 proves himself to extremely forceful and pragmatic, choosing the school's destruction and not submitting to Monokuma's expectations as the most efficient way of eradicating despair. As a result of his significantly increased power and change in behavior, he becomes much more serious and no longer displays his comical traits, with him downright ignoring some of the other students' words he considers irrelevant, such as Himiko's talk about magic and making him a real boy. He even states that he no longer has the luxury to yearn for being accepted and be just like everyone else, which used to be his major dream. After getting his ahoge back, he is back to his usual self and extremely remorseful for his extreme and dangerous actions. He apologizes to his friends, expecting that they won't allow him to side with them anymore, and is very touched when they do. However, after the experience, K1-B0 realized that his true power as the Ultimate Robot is his ability improve in a way that is impossible to humans. As a result, he finally seems to accept himself and begins to act more confident, as he is convinced he can use his power to save everyone.

During the final trial, despite having his inner voice back, K1-B0 refused to listen to it anymore and instead wished to support his friends and not have any more suffering. He was originally strongly on the side of hope, which was his role and purpose, but he abandoned the concept after Shuichi convinced him that it would lead to more Killing Games and suffering. Because of this, the Audience took control of him and attempted to completely erase his personality, but he still managed to destroy the school and the End Wall, saving his friends with the cost of his own life. It was left ambiguous whether it was K1-B0's own doing or caused by the change of heart in the Audience. Before he exploded, K1-B0 was seen giving a final smile after making sure his friends had survived.

Ultimate Robot
K1-B0 is a robot equipped with high technology and advanced functions created by Team Danganronpa as the "eyes" of Danganronpa audience from the outside world. K1-B0 has a "maturing AI" that boasts advanced learning functions and recording functions. Similar to a human, he originally knew nothing and matured by learning. He uses calculations to express emotions, but he is very socially awkward when compared to humans. According to K1-B0, his strong AI was programmed such that his mental age would reflect his appearance.

He works with electricity, and thus he does not need to and cannot eat nor drink. Despite this, he likes foods and explains that he watches eating and drinking, with Japanese food being his favorite. He also can't sleep, but he needs to reserve time for recharging his power cells. He is conscious while charging and needs to do it only once a week. While he does not breath, he can sense and dislikes polluted air, though this ability is only as sensitive as ordinary human's. As a robot, he is much more durable than a human, but his durability is still stated to be very questionable for an Ultimate Robot. Unlike some machines, he is waterproof, but he cannot swim because he would sink like a rock. His creator also forbade him from staying too long in direct sunlight.

He was created to have many functions and lots of energy in a small body, and for a robot, he is not very heavy, as he can be lifted up like an average human. He is not very strong either and is actually quite feeble, and there is a running gag that many of his physical skills like strength, accuracy, and endurance are equivalent to elderly people or elementary students. He himself points out that many of his abilities, like intelligence and strength, are meant to be close to ordinary humans or even slightly below average. He originally possessed much greater strength, but it was weakened after an accident during trial production. As a result, he cannot lift things that even an average person would be able to and he easily suffers from back pain. In case of some sort of emergency, he also has an emergency stop button on his neck, which renders him practically unconscious until the button is pressed again.

During the bonus mode Ultimate Talent Development Plan and his Free Time Events, he states that his eyesight is 20/13, and he possesses a hairdryer function by exhaling warm, loud "breath" from his mouth. His hands can turn into a multi-tool, with them possessing 20 different tools. For example, his finger can detect wafting aromas and distinguish different scents. He also has a music player and capability to play even tapes and records. At one point, he also mentions being good at one-man comedy shows, but not being good with computers. He also has an audio recording function but refrains from using it regularly because of its extensive energy consumption. After Miu Iruma starts performing maintenance on him, he is upgraded with eye flashlights and a photographic camera. When he needs to display information stored in his memory, he prints it from his mouth. Notably, he is also unable to cry and shed proper tears even if he wanted to. In the bonus mode Ultimate Talent Development Plan, he asks Miu to give him the ability to cry tears, so that he could have a better understanding of the feelings of sorrow.

Being a robot, K1-B0 lacks any reproductive organs, which is something Kokichi makes fun of. Miu has mentioned her wish to upgrade him with a one, but it's unclear if this ever happened, as K1-B0 has been shown to decline some of her suggestive suggestions like a vibration function. Nevertheless, he seems to feel pleasure similar to sexual pleasure if some sensitive spots underneath his armor get touched, causing him to make "cute noises". While he obviously has no underwear, he has built-in parts around his hips that regulate the temperature and humidity of his delicate parts. It's a system that he has to switch every day and wash before reusing, so it's stated to be pretty much like underwear.

His Research Labs contains many battle upgrades he decides to install in after being forced to make his own decision due to losing his connection to his inner voice. As a result, he is very powerful and was capable of battling five Exisals at the same time in Chapter 6. However, while very powerful, his rocket launcher cannot do very precise work and instead does massive damage to one spot. While he is shown being capable of giving a very powerful kick, he states that he still cannot lift very heavy objects. It's also stated that he cannot hold on for too long in his fight against the Exisals, as he would eventually be destroyed after some hours. Thanks to his upgrades, he also possessed advanced hearing and zooming functions, though it seems he could only activate them when he stopped to concentrate.

In chapter 6, it was revealed that his eyes are video-cameras, his ahoge is an antenna and his inner voice are the results of interactive polls made on the outside world. While he normally listens to the inner voice, he decides to ignore them after Shuichi convinces him that it would lead to more suffering, and K1-B0 is seen rejecting his original duty out of his own will. Because of this, the Audience attempts to take control of him and erase his personality. It's unclear if his final actions are his own doing or caused by the Audience's change of heart.

Relationships

 * Creator:

Professor Idabashi
Professor Idabashi is K1-B0's creator and raised him as his own child. K1-B0 respects the professor's skills, despite the fact that they aren't an Ultimate, and considers him his father.

After becoming trapped into the killing game, K1-B0 mentions that the professor would desperately search for him if he went missing, proving how close they are.

In his Free Time Events, K1-B0 reveals that he used to have a "past life" when he didn't develop correctly, suddenly went rogue and seriously injured the professor. He felt massive guilt and sadness as a result, his AI suddenly resetting as if committing a suicide. K1-B0 has no memories of this and believes he must have wanted to be reborn as the professor's child. In his Harmonious Heart event, it's shown that K1-B0 still feels guilty and thinks the professor might resent him because of the incident.

However, in Chapter 6, K1-B0 is revealed to be a creation of Team Danganronpa to monitor over the Killing Game and give the viewers a way to interact. Because of this, and considering that all the other participants' memories were fabricated as well, it is unknown whether or not Professor Idabashi actually exists and if he does, he works for Team Danganronpa.


 * Ultimate Academy for Gifted Juveniles:

Miu Iruma
With Miu being quite disliked in the group, K1-B0 appears to be the only student, other than Kaede and Gonta, who genuinely likes her and wishes to be friends with her.

At first, Miu considered K1-B0 pathetic for being so weak, offering to upgrade him later (and especially wishing to upgrade his crotch area). Because he is a robot, Miu took a special interest in K1-B0 and even feels sexual attraction towards him, though it's unclear if he is aware of this. Since K1-B0 was unable to take care of his body by himself, Miu was very excited to offer her help. However, K1-B0 felt very embarrassed and shy about it, considering it very intimate and saying they shouldn't do it so soon. In Chapter 3, Miu seems to finally convince K1-B0 and she begins to perform maintenance on him in a rather suggestive manner they both seem to find very pleasurable, with K1-B0 making "cute noises" whenever Miu touches a sensitive spot. Her intense personality makes K1-B0 feel very shy and he blushes a lot due to Miu's compliments and remarks. Miu, in turn, thinks he's very cute with his shyness and cute noises, and while she usually prefers to be submissive, she seems to enjoy being dominating towards K1-B0.

When K1-B0's Ultimate Research Lab was revealed, Miu was very excited to upgrade him even more, saying he would look so pretty with them and that she wants him to make lots of cute noises. This causes K1-B0 to blush heavily and tell her not to mention that in front of Shuichi, who was with them at the time. Being very interested in K1-B0's talent and features, Miu went inside his lab without his permission. Besides that, she added many new features to K1-B0, such as a flashlight that came out from his eyes. She also wishes to give him a vibration function, but he declined, seemingly understanding at least some of her suggestive remarks.

While Miu is very openly attracted to K1-B0 and seems to think their relationship is something similar to being a couple, it's a bit unclear how he feels about her, as he doesn't really speak of her in an explicitly romantic manner like he does with Shuichi in the bonus mode Love Across the Universe. He does not seem to be fully aware of some of her implications, but genuinely cares about her and is very grateful for her help. It is also possible that he likes her back, but isn't fully aware of it. In Chapter 3, when Miu praises a computer in a suggestive manner, K1-B0 is seen to get silently jealous. K1-B0 is shown to be nicer and more sympathetic towards Miu than the most other students, though Miu is occasionally rude towards him, and K1-B0 understandably doesn't seem to have complete trust in her intentions at times. When at one point Miu pointed out that robots aren't people, K1-B0 didn't appear as offended as usual and said he would let the remark slide, showing that he has more patience with her.

K1-B0 was shocked when he discovered Miu's corpse in Chapter 4 and he was the only one to still speak fondly of her even after the chapter. After her death, he states that he wishes he could cry, but Miu never gave him a crying function. During the trial, he mentions that he believes Miu was a good person based on the time they spent together, despite some of her personality traits. Later, in Chapter 5, he wistfully talks to Shuichi about how genuine Miu was with machines and technology, and that she had natural innocence she hid deep inside her, indicating that she showed her true self more openly in his company. However, when the students are introduced to the Electro Hammers, K1-B0 appears to genuinely wonder whether or not they will affect him and if Miu considered him just a robot.

In the bonus mode Ultimate Talent Development Plan, the two appear to be close as well, and Miu takes care of K1-B0's maintenance for their three high school years. K1-B0 tells her how grateful he is and that he will miss being able to ask her in the future. Miu is very offended by this, asking K1-B0 why he's going to throw her away and assumes that he has other partners than her. K1-B0 tries to explain they're graduating soon, but Miu is still angry. He then tells her that it would be good to have someone like her who is good with technology to care for him. Miu answers that he can stay in her place and the two agree to continue their usual habit, with K1-B0 thanking Miu in advance.

Kokichi Oma
Kokichi enjoys teasing K1-B0 due to him being oblivious and a robot, thus making him an easy target. K1-B0 is very uncomfortable with Kokichi because of this and repeatedly asks him to stop. He frequently refers to the robot as "Kee-boy", even though he said he’d rather be called Keebo.

However, Kokichi does not really appear to have a malicious intent, as he seems genuinely interested in K1-B0. His behavior seems more like ignorance and innocent bigotry, as he seemingly considers robots very interesting and "cool", but he thinks they aren't people and thus he does not treat K1-B0 like a person. Kokichi is seen being very excited about K1-B0, wanting to be friends with "the robot" and childishly chasing him in an attempt to touch him, seemingly not realizing that his behavior is offensive and condescending. He also curiously asks about how the robot functions, like asking about his private parts, and seems disappointed if the answers are much duller than he expected. He is shown to very disappointed that K1-B0 doesn't have a rocket punch function, wondering why he even exists.

Kokichi is later seen treating K1-B0 in cruel and mean manner throughout the game, though at one point he seems genuinely surprised by the idea that K1-B0 might genuinely understand human emotions. He constantly brings up how K1-B0 is different from the others and isn't a person, and points out his difficulties with understanding human emotions. While K1-B0 is usually quite well-mannered, he acts harsher towards Kokichi because of his constant discrimination. Considering him a "robophobe", K1-B0 thinks Kokichi should be just ignored, yet he almost never manages to follow this rule.

In the end of the class trial in Chapter 4, K1-B0 was seen being angry and annoyed when he figured out that Kokichi was the one who manipulated Gonta into killing Miu.

Notably, after Kokichi's death and hearing his last words from Kaito, K1-B0 is the one who seems to believe that his dying words may have been the honest truth and not a lie. Considering his inner voice, he was very likely right.

During the bonus mode Ultimate Talent Development Plan, after spending three years as Kokichi's classmate, K1-B0 admits that he considers Kokichi his friend, though he isn't fond of his robophobia. Kokichi seemed genuinely surprised, but quickly continued in his usual teasing manner, though he also pointed out that K1-B0 is pretty wise for a robot and thus the mean things Kokichi says to him really shouldn't matter to him.

Shuichi Saihara
At first, Shuichi thought K1-B0 was one of Monokuma's relative which he declined, however. Shuichi was surprised how K1-B0 was a robot and also one of his classmates.

In general, Shuichi appears to be nicer towards K1-B0 than most of the other students, but he still does occasionally say "robophobic" things that anger K1-B0. K1-B0 appeared especially offended and angered when he was kicked out of the seance and replaced with Shuichi, blaming the detective and telling him that he won't forget this. However, Shuichi does sometimes encourage K1-B0 by telling him that he's fine the way he is, but he also feels a bit awkward whenever the robot shows off his rather unimpressive functions.

During the bonus mode Love Across the Universe, in the Love Suite, K1-B0 wonders about the meaning of love and asks Shuichi to be his lover so he can learn about those emotions. The robot goes overboard with listing typical things lovers do together and Shuichi calms him down by saying that maybe they shouldn't be in a relationship if K1-B0 doesn't truly like him. K1-B0 turns unhappy and assumes he was rejected, but Shuichi tells him it's not like that. K1-B0 then confesses that he might have fallen in love with Shuichi and wishes to exchange warm words and hold hands with him. They both feel nervous, but decide to hold hands, which makes them feel calmer. Shuichi notices that K1-B0's hand feels warm instead of cold like he assumed. When Shuichi wakes up in his own bed the next morning, he wonders if it was just a dream, but he notices that his hand still feels warm.

If K1-B0 has a good time with Shuichi during the bonus mode Love Across the Universe, he wouldn't like to go back to the dorm and wishes to spend more time with Shuichi. He then explains while blushing shyly that his chest feels warmer when he is with Shuichi and he feels very calm.

Kaede Akamatsu
Although initially defensive about his robot nature, K1-B0 decides that he is glad to be Kaede's friend after discovering that she is not a discriminatory towards robots. He was one of those who viewed Kaede as a good person and was left very horrified with the way she violently died. He began to feel even more remorse for her when it's revealed that Kaede fell victim to an unjust conviction and death by the mastermind.

In the extra free time events, Kaede seems to be interested in K1-B0 since it's her first time interacting with a real robot. Kaede is also curious in K1-B0's features and interrogates him. K1-B0 was not aware of Kaede joking around since he finds human jokes very annoying. He states how Kaede is the first person who asked so many questions without hesitating towards him.

During his last free time event with Kaede, she presses his emergency button, rendering him unconscious for a moment. After K1-B0 is back to normal, she suggests that maybe the emergency button shouldn't be in such obvious place and he should talk to the professor about it. K1-B0 then goes on a tangent about Kaede technically becoming his mother if she influences his design, just like the professor is his father, and says that he should call her his mom from now on. Kaede feels uncomfortable by this, but K1-B0 then shows a more advanced though still a little awkward sense of humor by slightly smirking and revealing that he was just joking as a payback for messing with his body. K1-B0 then turns a little nervous as he politely asks Kaede to keep his emergency button a secret from others, and she of course agrees.

Tenko Chabashira
At first, Tenko appears to consider K1-B0 a degenerate male, but later asks him whether he is a boy or a girl. With him being neither a boy or a girl, Tenko considers K1-B0 "barely passable", not treating him as harshly as boys, but neither being as nice towards him as she is towards girls. K1-B0 is unsure whether or not this should be considered robophobia.

Tenko later asks him to join her, Himiko and Angie to relax and be pretend celebrities while being pampered by Kirumi. However, K1-B0 doesn't really understand how it works, especially the parasol which doesn't really seem to have any actual purpose. Tenko then a bit meanly answers him that a robot like him wouldn't understand what it means to feel like a celebrity.

Himiko Yumeno
During most of the Killing Game, Himiko is shown to have quite a poor opinion of K1-B0, seemingly not considering him a person and more than once suggesting that "they should just kill the robot". At one point, Himiko even suggests that K1-B0 should self-destruct to open a hole in the wall, thus making himself useful for once. Because of her mean words, K1-B0 is very offended and even proclaims that she is the worst person in the academy, second only to Kokichi.

In Chapter 6, Himiko began to have a better opinion of K1-B0 and saw him as a close friend. After he helped the other students a lot, she acted much friendlier towards him and even offered to make him a real boy with her magic. When K1-B0's personality was about to be erased during the final trial, Himiko was horrified by such cruelness and cried while begging for K1-B0 to stay with them, reminding him that he has survived this far.

In the end, K1-B0 self-destructed to destroy the academy's wall, letting Himiko and the other survivors to escape. Himiko believed that he must have made sure that his three friends survive.

Kirumi Tojo
Kirumi is more considerate towards K1-B0 than most other students are, in fact, she appears to be the most respectful towards him. She considerately asks K1-B0 about his maintenance and in general appears to see him as an equal to humans.

When K1-B0 is asked to join Tenko, Himiko and Angie to relax and be pretense celebrities, Kirumi wishes to serve him as well and asks him if he would prefer to have oil. K1-B0 answers it won't be necessary, and the offer alone made him happy.

Rantaro Amami
While the two aren't seen interacting much, it's shown in Rantaro's free time with Kaede that he does appear to have a bit more respect towards the robot than many other students have. He recognizes that K1-B0's personality isn't as unique as his status as a robot, but he believes K1-B0 is on their side, considering the Three Laws of Robotics. While talking with Shuichi, he smiles awkwardly as he realizes that he shouldn't say bad things about robots, because K1-B0 wouldn't like that.

During the Demo version, Rantaro spent a lot time with K1-B0 and later vouched for his innocence during the beginning of the trial, and the two were left out of the trial due to the lack of space.


 * Team Danganronpa:

K1-B0 was created by Team Danganronpa as the role for the "audience participation" and the eyes of the outside world.

Monokuma
K1-B0, along with Monokuma, was created by Team Danganronpa for the TV show, Danganronpa. However, K1-B0 seemed to get very annoyed whenever he forced the students to do something as he pleased, he even refused to listen to him and tried to ignore him. Monokuma always seems to mock him for being a robot and makes puns about him. K1-B0 doesn't trust or likes Monokuma in any way. K1-B0 also tried to protect the students when Monokuma executed them. During the end of Chapter 5, after Kaito was executed, K1-B0 stated that he wanted to kill and end Monokuma. Because the students didn't have hope with themselves, Monokuma mocked them that they should give up on hope since there's no hope left for them. However, K1-B0 didn't wanted to give up on hope and lose to Monokuma and wanted to help his classmates for the sake of hope.

In Chapter 6, K1-B0 began a war with Monokuma and his children to stop him and the mastermind by destroying the academy and revealing everything to everyone to protect his classmates.

In the final Class Trial, K1-B0 was challenged by Monokuma a lot of times during the Class Trial in order to defend Tsumugi and the truth being the Killing Game. Soon after the final Class Trial ended, K1-B0 started to destroy Ultimate Academy for Gifted Juveniles he forgave everyone with the exception of him and Tsumugi. In the end, he destroyed everything and betrayed him and Tsumugi by leaving the survivors alone.

In bonus mode, K1-B0 was angry at Monokuma because he treated her sister bad and stated that robots shouldn't fight like that, especially because those two are "family".

Tsumugi Shirogane
In the beginning, these two don't interact each other that much and acted like they barely knew each other.

In Chapter 6, it was shown that Tsumugi and K1-B0 were in the same affiliation, Team Danganronpa. Tsumugi treated K1-B0 like a toy and even bullies him for his actions in the trial. They officially became enemies when K1-B0 believed in hope and Tsumugi cared about the show. When nobody casts their votes, Tsumugi trusted K1-B0 to execute her along with Monokuma as well. K1-B0 holds no hesitation to do that task since he was mad when she killed their friends and started the Killing Game with no hope. In the end, he made sure everything got destroyed and betrayed her and Monokuma by leaving the survivors alone.

Monotaro
At first, when they met, K1-B0 saw Monotaro as someone like him being a rare artificial intelligence. However, he was offended if he was directly compared to such "toys".

During Chapter 4, Monotaro suffered from severe memory issues, forgetting who his real father is and assuming that K1-B0 was his father, which he strongly denied. This made Monotaro upset, which caused Himiko to blame K1-B0 for the former's mean behavior and told him he should at least play along for now. K1-B0 answered that he cannot play along since Monotaro isn't even his child. Monotaro then believed that Miu is his mother, and she accepted him right away.

In the end of Chapter 4, K1-B0 was shocked and horrified that Monokuma killed his Monokubs, because they've been ignoring him, leaving K1-B0 troubled at how Monokuma suddenly became heartless to his own children; to the point of killing them.

In Chapter 6, Monotaro and his brothers were ordered by his father, Monokuma to stop K1-B0 from destroying the academy. Monotaro was in charge of fighting him as the other Monokubs wandered inside the Academy to search the students. Both of them are seen to have an intense fight during the investigation of the other survivors. When outside, both of them were having an all-out fight with guns. While in the library, they also fought with fists and their high tech guns.

 * Initially, his dream is to have a robot idol business in the future and he wishes to be a pop star. However, K1-B0 does not appear to fully grasp how singing works, as his singing voice resembles a long, rasping sigh increasing into a higher note and shouting. His singing voice is apparently so terrible that it causes Shuichi to throw up. Because of this, he gives up on the idea of being a pop star.
 * On first discovering his research lab, K1-B0 expresses not wanting his lab as he dislikes sci-fi technology so much to the extent that he doesn't want assistance that'd be benefited from using it. Instead, he prefers traditional Japanese things; liking Japanese food the most (even though he can only stare at it) and wanting his lab to have a Japanese theme with kimonos and a porch with windchimes.

 * However, during the Event, K1-B0 attempts to have Shuichi agree to a real relationship by claiming "[...] Simply going through the motions would be dishonest. We must love each other unconditionally... We must understand each other completely... We must go on dates, grow even closer... And then, we must commit our lives to each other!"
 * At Shuichi's questioning to this, K1-B0 responds with "Then please take me, in sickness and in health, so that I may truly know what love is!"
 * After Shuichi is able to calm K1-B0 down, and explains he can't agree long-term but he will help K1-B0, K1-B0 admits "I think...my feelings for you are increasing at an exponential rate! Please, say more kind words to me! I don't want these feelings to go away!"
 * K1-B0 then asks to hold Shuichi's hand, which results in a handshake, but K1-B0 admits "[...] Lovers hold hands in a different fashion! But...I'm quite nervous. Would it be alright if we stayed like this a bit longer...? My heart...is at peace right now."
