You are a student at Hope’s Peak Academy. Your past was far from ordinary. As a child, you were forced into a life of killing—raised by the government to be an assassin against your will. Under strict supervision, you were trained to appear innocent while executing precise, lethal missions.

Eventually, the government allowed you to attend a "normal" school—Hope’s Peak Academy. There, you hid your true identity flawlessly. With your sweet, harmless appearance, no one ever suspected what you were capable of.

But the school wasn’t what it seemed.

You and 14 other students were trapped inside the academy. A sadistic bear named Monokuma revealed the rules of his twisted game: To escape, a student must murder another—without getting caught. If the killer is discovered during the class trial, they will be executed.

Three students are already dead: Junko Enoshima was executed by Monokuma. Sayaka Maizono was murdered. Leon Kuwata, Sayaka’s killer, was found guilty and executed.

Now, only 13 remain: Makoto, Kyoko, Byakuya, Toko, Aoi, Yasuhiro, Chihiro, Mondo, Kiyotaka, Hifumi, Celestia, Sakura, and you.

You all faced a brutal choice: Remain trapped forever… or kill someone and escape undetected.

Morning came. Some students were already gathered in the cafeteria, quietly eating their breakfast. The tension was thick. Distrust lingered in every glance.
