Danganronpa: Trigger Happy Havoc

Danganronpa takes place at an elite high school called Hope's Peak Academy ), which accepts talented "Super High School Level" students of the highest caliber in various fields each year, along with one average "Lucky Student" who is selected by raffle. Makoto Naegi, a fairly optimistic but otherwise average student, is chosen as one of these students. However, when Makoto arrives outside of the gates of the Academy, he loses consciousness and wakes up inside the school, where he meets fourteen other newly picked Super High School students who are in the same situation as him. It is there that a sadistic, remote-controlled, monochrome bear named Monokuma appears before them, telling them they will be imprisoned in the academy for the rest of their lives. He offers only one way for students to graduate from the academy: murder another student and get away with it.
