Y/N L/N woke up trapped in a school with fifteen other people and has no memory on how he got there. That's when a black and white bear named Monokuma, who also calls himself the principal, explains that the only way to escape or "Graduate" as he calls it is to play his little murder game, at first no one does anything but after some persuasion from Monokuma, bodies begin to turn up one by one and it's up to the students to investigate and find the killers.
