Hifumi Yamada (山田 一二三), 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 the Ultimate Fanfic Creator (超高校級の「同人作家」 lit. Super High School Level Dōjin Author)

Hifumi has a verbose manner of speaking, often going on long-winded tangents about his interests such as anime or fan fiction. He also has a tendency to casually make creepy or perverted comments in the middle of conversations, especially about or to women. He can also be oblivious to how others perceive him, as shown when Toko says he smells like a "big fat ugly donkey" — he couldn't tell if that was an insult or a compliment. Hifumi is extremely passionate about anime and fan fiction and has little tolerance for anyone less dedicated to them than himself, calling them "slackers". His dream is to create a story so powerful it'll inspire others to create their own stories as well.
