Hifumi Yamada (山田 一二三 Yamada Hifumi), is a student in Hope's Peak Academy's Class 78th, and a participant of the Killing School Life featured in Danganronpa: Trigger Happy Havoc. His title is Ultimate Fanfic Creator.
In the game, he is voiced by Kappei Yamaguchi in the Japanese version of the game, and by Lucien Dodge in the English version of the game.
In the anime, he is voiced by Kappei Yamaguchi in the Japanese version of the anime, and by Tyson Rinehart in the English version of the anime.
Hifumi is an overweight young man with black hair and a short pointed ahoge. He wears a pair of black thick-rimmed glasses. He is dressed in a white button-down shirt, an orange tie which has a patterned double-headed blue arrow upon it with the smaller arrowhead pointing upwards and the larger arrowhead pointing downwards to the tip of the tie, a pair of dark gray trousers, and white trainers. Over his shirt is a light grey, unbuttoned cardigan and on his back is an orange backpack.
Hifumi has a verbose manner of speaking, often going on long-winded tangents about his interests such as anime or fanfiction. He also has a tendency to casually insert creepy or perverted comments in the middle of conversations. Hifumi is extremely passionate about anime and fanfiction, and has little tolerance for anyone he feels has a poor or neutral opinion about them. Their importance of them is so deep, Hifumi has said it's his dream to create a story so powerful it'll inspire others to create their own as well.
He refers to others in a very formal manner, calling them "Ms." or "Mr." Last Name, for example he calls Makoto "Mr. Naegi". In the original Japanese game, he uses the honorific suffix -dono as well as their full name, for example "Naegi Makoto-dono". This proves to be a key piece of evidence later during the trial for his murder as he mutters "Yasuhiro", Celestia Ludenberg's real last name as opposed to it being Yasuhiro Hagakure's first name.
Although having a somewhat misanthropic look on society, Hifumi will not stand for indecent crimes against those he holds in deep regard, and even went so far as to kill Kiyotaka to avenge the harm he believed he had done to Celestia.
Hifumi seems to have an addiction to Diet Coke, and can get to the point of hallucinations if he goes too long without having it, and becoming nearly violent.
