Hifumi Yamada

 is one of the characters featured in Danganronpa: Trigger Happy Havoc and a participant in the Killing School Life.

Hifumi has the title  enrolled in Hope's Peak Academy's Class 78th.

Hifumi was a famous doujin author who was able to sell ten thousand copies of his work at the culture festival at his school. He also claimed to favor 2D girls in comparison of 3D ones, though his attitude around them proved otherwise.

Hifumi was killed by Celestia Ludenberg, who in turn, had manipulated him into murdering Kiyotaka Ishimaru in Chapter 3.

Hifumi played a minor role in Danganronpa 3: The End of Hope's Peak Academy.

Appearance
Hifumi is around 19 years old, though he believed himself to be 17 in Danganronpa because of the memory loss. undefined

He is an overweight young man with black hair and a pointed ahoge. He also wears glasses. He is dressed in a white shirt with an orange tie which has a blue arrow at the tip pointing upwards. Hifumi wears a grey, unbuttoned cardigan over his shirt and carries around an orange backpack. He wears black trousers and white trainers.

He wears not-for-sale underwear based on Robo Justice.

Personality
Feeling misunderstood by his peers and resenting them for it, Hifumi comes across as creepy and perverted, possibly due to his tendency to make an innuendo over some things that other students said; a trait that creeps Leon Kuwata out. He also has a habit of putting anime references in his speech.

In his Free Time Events, it is shown that Hifumi is very passionate about Princess Piggles, a female lead in his favorite anime series, Demon Angel☆Pretty Pudgy Princess. Although having a somewhat misanthropic look on society, Hifumi will not stand for indecent crimes against those he holds in deep regard and will even go so far to kill the person to stop them from doing any more harm and avenge his friends.

Hifumi has a particular dislike toward people who supposedly don’t understand the true meaning of doujin, even going as far to claim that they're ruining everything.

Ultimate Fanfic Creator
Befitting his title Hifumi is gifted at writing and drawing manga. His dream is to 'save' other people by making a doujin that will inspire them to create their own.

Prior to the Tragedy
Before his own introduction to anime and doujinshi, Hifumi was heavily involved in his middle school's student council. He also states that he sold ten thousand copies of his work at the culture festival in his school. Many students thought Hifumi's work would spoil the festival, but Hifumi was proud that he proved them wrong. Because of his doujinshi, he has met many other authors.

He used to attend Marufuji High School and was later invited to attend Hope's Peak Academy's Class 78th as the Ultimate Fanfic Creator.

Episode 11 - Goodbye, Hope's Peak Academy
Hifumi was seen inside the old school building with his classmates. After agreeing with Jin Kirigiri's proposal, Hifumi and the others immediately worked in sheltering the building. Hifumi was helping Sakura Ogami in sheltering the windows and he was surprised that she only used her bare hands to lock the windows.

During the Tragedy
One year later, the Tragedy occurred. During the Tragedy, Jin Kirigiri, the Headmaster of the Academy, planned to seal the school building and let the students live forever inside the Academy in order to protect them from the destruction. His plan was agreed by the class, and they sealed the building together and lived peacefully inside it for a year without knowing that the Ultimate Despair members were already in their midst.

The true Ultimate Despair took away the 78th Class' school memories so they could participate in the school life of mutual killing.

Prologue - Welcome to Despair
When Makoto Naegi arrives, Hifumi declares that their is 15 students in total, and he confirms that it was abnormal the way they all fell asleep. When Makoto introduces himself, Hifumi asks Makoto if he was "one with 2D relationships". Upon Makoto's confusion, Hifumi then talks about his title and how others reacted about his work. Hifumi then states that Makoto will come to the light after seeing Hifumi's work. He then ends the conversation with a suggestive comment, making Makoto leave.

Chapter 1 - To Survive
During the first investigation, Hifumi was revealed to be the janitor, with the key to the trash room. He was asked by Makoto to open the shutters so the two could investigate and discover a bloody shirt piece (Leon's) and a shattered ball that was used to turn on the incinerator through the shutters.

Chapter 2 - Boy's Life of Despair
During the second investigation, Hifumi was the person who found Chihiro Fujisaki's broken e-Handbook in the sauna.

Chapter 3 - A Next Generation Legend! Stand tall, Galactic Hero!
Hifumi later developed a crush on the artificial intelligence created by Chihiro - Alter Ego. This one-sided relationship annoyed Kiyotaka, and as a result, the two clashed frequently. This dispute was taken advantage of by Celestia, who stole Alter Ego and convinced Hifumi that it was Kiyotaka who stole it.

Celestia enlisted Hifumi as her accomplice (who thought that Celestia was his), by telling him that Kiyotaka forced her to steal Alter Ego and was planning to kill Hifumi. The two frame Yasuhiro Hagakure by putting him in the Robo Justice (ジャスティス ロボ Jasutisu Robo) suit, and make it look like the robot was responsible for both Hifumi's and Kiyotaka's “deaths” - when in fact, Hifumi was only pretending to be dead by putting transfusion blood on himself.

After Hifumi bringing himself and Kiyotaka's body to the Art Storage Room, Celestia finishes her plan and kills him. After the Class Trial, Celestia states that Hifumi never suspected that he would be the next victim to be murdered, and thought that Celestia would kill someone else instead.

When he was dying, Hifumi presumably regain his memory back about everything that happened before the High School of Mutual Killing. Aoi Asahina asked him who's the blackened behind both his and Kiyotaka's murder, but due to his injury, he could only say “Yasuhiro” at the end.

Episode 11 - All Good Things
Hifumi, Celestia, and Kiyotaka appear behind Kyoko in Makoto's hallucination, trying to persuade him to commit suicide.

Execution
'''Watch Out, Princess Buuko! Great Monster Invasion''' - A gigantic Princess Buuko comes flying to a place where an enormous Monokuma is rioting at. Both start fighting. Hifumi, who is stuck between them is being hit from both sides. At the end, he dies when being hit by 'Certain Kill' beams from both simultaneously. This is only described in the official Visual Fanbook.

Fujiko Yamada
Fujiko is Hifumi's older sister, and apparently the person closest to him, which is confirmed by the fact that she became his Captive.

Celestia Ludenberg
Celeste often asked Hifumi to do things for her, such as making her tea. She bossed him around and was angered when he did not do things the way she pleased. Celeste intimidated and manipulated Hifumi, but he succumbed to her charm, essentially becoming her pawn and eventually being murdered by her later in Chapter 3.

Shortly after Hifumi and Celeste's deaths, the survivors found a picture of the two and Sayaka Maizono. In it, Celeste seems to be angry with Hifumi, indicating that their relationship was the same during their time in high school.

Toko Fukawa
Hifumi appears to think his writing is better than Toko's, making her feel insulted. The two fight in Chapter 2 over their writing styles. Hifumi assumes Toko likes boy on boy action and that her work is isn't worthwhile.

Leon Kuwata
Despite how the two really weren't that big of acquaintances, the brief interactions with each other showed that Leon didn't like Hifumi. The baseball star kept calling him "fatty" instead of his name, and was often disgusted and creeped out by Hifumi's perverted nature and innuendos. It became so bad that Leon often accused him of perverted acts, like offering to be in charge of trash duty so he could go through the girls' trash.

Makoto Naegi
Hifumi seems to be friends with Makoto, often attempting to educate him on doujinshi. While Makoto was annoyed by Hifumi's constant ramblings about manga and anime he desired to see his hope bringing manga when it was complete.

Alter Ego
Hifumi developed a crush on the AI due to it listening to what he has to say. Alter Ego itself was not interested in Hifumi, though. He also referred to Alter Ego as a female, despite the fact that it was modeled after Chihiro. Hifumi told Alter Ego his "hobbies", which were probably perverted.
