Danganronpa: Kibou no Gakuen to Zetsubou no Koukousei The Animation

A group of highly skilled students, along with one randomly selected individual, attend Hope’s Peak Academy. Upon arrival, they discover they are trapped under the control of a robotic bear named Monokuma. The principal enforces a twisted rule: to escape, a student must commit murder and avoid being identified as the killer. After each killing, the remaining students participate in a trial to determine who is responsible.
