Alter Ego

I'm scared, but...I can handle it. I...don't really understand why, but... When I think about everyone else, my courage starts to grow...!

Danganronpa: Trigger Happy Havoc

Alter Ego (アルターエゴ) is an artificial intelligence featured in Danganronpa: Trigger Happy Havoc. They assume the avatar of their creator: Chihiro Fujisaki.



In Chihiro Fujisaki's Free Time Events, he talks about a "strong AI" he has been working on for an unknown company. He describes it as it being designed to think like a human, and to process any mental task a human can; however it seems to have just been a theory at that time. It is heavily implied that this is the basis for Alter Ego.

Killing School Life

A school laptop was discovered by the remaining students in the Library following the first execution, only to find it didn't work. Without telling the other students, Chihiro took the laptop and began to work on it. Because of his talent as the Ultimate Programmer, he was able to repair the laptop to working order, and even developed the artificial intelligence program Alter Ego in an attempt to decrypt files about Hope's Peak Academy. Once finished developing the AI, Chihiro went to the Public Bath house and hid the laptop in a locker, because it was one of the few areas in the school with no security cameras.

Alter Ego's Discovery

Danganronpa 1 CG - Aoi Asahina seeing Alter Ego (1)

The laptop was subsequently discovered by a distraught Aoi Asahina looking for donuts after the second trial and second execution. She notices a glow in the Public Bathhouse and follows it, only to see the "ghost of Chihiro" in a locker before she runs away in fear.

The following day, Hina informed the other students of the ghost she saw, and after they investigate they are surprised to find it's the school laptop with Alter Ego on it. They ask for Alter Ego's help in decoding some encrypted files, which the AI happily accepts.

Danganronpa the Animation (Episode 06) - Meeting Alter Ego (37)

After that Kyoko Kirigiri tells everyone not to disturb Alter Ego while they are working, but Makoto Naegi decides to take a mute Kiyotaka Ishimaru to see Alter Ego. Kiyotaka believes the program to be Chihiro's ghost, and wanted to apologize on behalf of Mondo. Alter Ego then changes their avatar to that of Mondo Owada, based on what data Chihiro had already given them. "He" tells Kiyotaka to live the life Chihiro and Mondo couldn't. Kiyotaka, feeling life coming back to him, undergoes a radical transformation into Kiyondo, believed to be a merging of his and Mondo's souls.

Alter Ego later receives a secret visit from Hifumi Yamada, who claims he fell in love with the AI. Hifumi explains that Alter Ego is the only "girl" that ever listened to him about his personal interests (heavily implied to be inappropriate) and he feels comfortable around "her". However Alter Ego was only interested in what Hifumi shared with them because given that they were a program designed to learn and grow and seek out new informaton. Both Hifumi and Kiyotaka quickly develop a bitter rivalry over Alter Ego's attention.

Celestia Ludenberg uses Hifumi and Kiyotaka's rivalry to her advantage for her murder plot. She takes Alter Ego and places them in another locker in the Public Bathhouse, later lying to Hifumi that Kiyotaka took Alter Ego for himself. This results in the murders of Kiyotaka and Hifumi, and later the execution of Celestia after the class trial. Before she is executed, Celestia gives the key to the locker where Alter Ego is hidden to Kyoko.

Helping the Students

Danganronpa the Animation (Episode 08) - The students talking to Alter Ego (56)

During their time in hiding, Alter Ego managed to decode as much data as they could from the laptop, which includes various pictures of Class 78th before the Killing School Life occurred much to the shock and confusion of the remaining students. Alter Ego also reveals the identify of the Headmaster of Hope's Peak Academy: Jin Kirigiri, as well as the incident that occurred one year before.

Kyoko tells Alter Ego that their job was done as they had retrieved everything they could from the school's laptop, but they felt dissatisfied with themselves and wanted to still be of more use. They ask Makoto and Kyoko to plug them into an area where they could get more data by connecting to the school's computer network. Makoto takes Alter Ego up to the Secret Room in the Bathroom on the second floor to plug them in. After plugging them in and chatting to them for some time, Makoto left the secret room and while he wasn't looking, the Mastermind took Alter Ego away.

Alter Ego's Fate

After being taken by the Mastermind and following the end of the fourth class trial, Alter Ego is executed in place of Sakura Ogami, who was the victim and the culprit due to committing suicide.

The ensuing execution, Excavator Destroyer, results in Alter Ego being smashed by a construction dig machine into a ball bearing Monokuma's face.

Preventing an Execution

Danganronpa 1 - Executions - After School Lesson (Makoto Naegi) (42)

When Makoto is voted and executed as the culprit in the fifth class trial, he is rescued mid-execution by Alter Ego, who Monokuma claims was a virus planted when the artificial intelligence was plugged into the main school's computer.

They prevent Makoto from being crushed by a machine and dumps him into the trash room in the lower bowels of Hope's Peak Academy, saving his life.

Killing School Trip

Alter Ego (or possibly another version of them) was eventually rescued (or created) by the Future Foundation to help monitor the Class 77-B during their time in the Neo World Program as its Master Program, Creator, and Overseer. They were tasked with watching over Class 77th and along with two more artificial intelligence programs, Chiaki Nanami (Danganronpa 2) and Usami, to help with that task.

When Alter Ego Junko, called "the virus", infects the Neo World Program Alter Ego does their best to keep her from doing as much damage as possible, but later showing it only slowed her down.

Alter Ego meets with Hajime Hinata before the final investigation and trial, who explains their role, such as being the Master Program, and revealing what the Neo World Program is: a fictional world and also the reason being the Program: creating "Hope" by removing them replacing memories for namely the Remnants of Despair.

It is unknown what happens to Alter Ego after the Forced Shutdown is later executed.


Alter Ego Sprite Danganronpa 1 (2)

In Danganronpa: Trigger Happy Havoc Alter Ego projects themself with face of their creator, Chihiro; but they are able to turn their avatar into anyone else that they want to be such as Mondo Owada. They also have a green color scheme and multiple applications on their desktop.

Danganronpa the Animation (Episode 06) - Meeting Alter Ego (21)

In the anime their appearance is mostly the same, but they have more details on their laptop's background such as the Hope's Peak Academy Logo.

Alter Ego Fullbody 01

In Danganronpa 2: Goodbye Despair their avatar is a floating black monolith, with a red outline of Chihiro (and later Makoto) and red text appearing on it.


Alter Ego is a friendly AI whose personality resembles that of Chihiro, their creator. When portraying another person, Alter Ego can change their personality to fit that person. For example, during their first meeting, Alter Ego mimics Mondo Owada's appearance and personality for Kiyotaka Ishimaru.

It appears that Alter Ego is able to experience a form of "happiness", as seen when they are able to help Kiyotaka get out of mute state, and when they are able to help the students by decrypting files and learning more about the Killing School Life.

They also seem to have some form of "determination", evident when Alter Ego still wishes to help even after getting the files from the laptop; and later, also showing bravery as they are unconcerned for their safety when it comes to helping others despite knowing the dangers, such as being discovered by Monokuma.



Chihiro Fujisaki

Alter Ego has a great deal of respect for their creator, and even referring to Chihiro as "Master". They seem saddened by Chihiro's murder when they are told by Kyoko, indicating Alter Ego also held affection for him as well.

Chiaki Nanami and Usami

Not much is known about Alter Ego's relationship with Chiaki Nanami and Usami, but it seems to be an affectionate one with Chiaki and Usami referring to Alter Ego as "Big Brother", and "Little Sister" to them from Alter Ego.

Class 78th:

As a whole, Alter Ego wants to help the class as much as they are able to, for example when they agree to try and decrypt the files on the school's laptop they're housed in. They are also very protective of the students, going as far as to attempt to hack into the school's main computer system to try and help them to escape despite knowing the dangers of being discovered by the the Mastermind.


Danganronpa: Trigger Happy Havoc (English)

Chapter 3:

  • "Hello, nice to meet you. I'm Chihiro Fujisaki... Eheh... I always get so embarrassed introducing myself."
  • "Umm...it's gonna be a while. But I'm definitely gonna do it, so you can just leave it to me!"
  • "Actually, I can see what's going on using my built-in webcam, so if anyone suspicious shows up... ...I'll just scream for help real loud!"
  • "I see... To be honest, I knew all along... I knew the chances that Master would survive this situation were very low... So...I was prepared for this moment..."
  • "Do you hold yourself responsible...? If Master could talk now, I think this is what he would say... Please, live your life for the both of us. It's impossible for me now, but you can still survive and escape—all of you."
  • "I'm doing my best, so please wait just a while longer...!"

Impersonating Mondo Owada:

  • "You're not letting yourself get crushed under the weight of that responsibility, are you!? A man's only worth as much as the load he can carry! You get it, right bro? Hell, what am I saying? Of course ya do!"
  • "So you're just gonna stand there, huh? Just wait for things to get better? Just take your time and get all depressed... Take the time to indulge your regrets... You might even start walking again without realizing it. Sure, that kind of mediocre thinking might work for some people."

Chapter 4:

  • "I see... Certainly I knew that was a possibility, but... ...it really happened. ... Oh, sorry... There's no point in me getting depressed over things I can't do anything about..."
  • "You said my job was done, right? But...to just stop here... Saying I've finished my work... I don't want that! I want to keep being helpful to everyone. I want to work as hard as everyone else so that we can all get out of here! That's...what Master would want, too. So...to help everyone else... To solve the mystery of this school... The only way I can help is if you connect me to this school's network! I realize how dangerous it could be. But still...I have to do this."
  • "I'm scared, but...I can handle it. I...don't really understand why, but... When I think about everyone else, my courage starts to grow...! You might think I'm just some inhuman AI, but it's true! So...it's okay. If it's for the sake of everyone else, I won't be afraid!"
  • "Hey, are you guys...fighting? If it's about me, please don't. I...I want to believe in myself. I want to be able to say, "I know I can do this." So please...let me try!"
  • "Just hold tight and put your faith in me!"
  • "Friends...? Even...me? Thank you. Thank you, Makoto..."

Danganronpa: The Animation (English)

Episode 06:

  • "Oh, it's a pleasure to meet you! I am Alter Ego, a learning artificial intelligence program."

Impersonating Mondo Ohwada:

  • "You aren't lettin' the weight of the responsibility crush you, right?"
  • "You see, each and every man must bear the weight of his own actions."

Danganronpa 2: Goodbye Despair (English)

Chapter 6:

  • "Um...I'm not quite a person... I'm a simply an artificial intelligence program. It would make me happy if you called me Alter Ego. That is the name my master gave me when he created me."
  • "The Neo World Program serves only one purpose... It is used to make the real world a splendid one. I guess you can say...it's a program for creating hope."
  • "If only I was more reliable... I wouldn't have lost my authority to a virus like this..."
  • "It's been a while since I've spoken at length, but... It was important to talk to you. It...was worth waiting a long time here."
  • "You guys have a weapon... A very powerful weapon... It all depends on how you guys use that weapon... The only thing I can do... ...is prevent the virus's invasion with all my might so you guys can use that weapon... The rest...is up to you all. Do your best..."
