Dangan Ronpa: The Mutual Life of Killing in the City of Despair

Sixteen of the Ultimate Students from Hope's Peak Academy wake up in a strange apartment room. They soon get out of the white room, similar to that of a mental institute, and find out from a familiar face that they're trapped in the city, and will be forced to murder each other. Aisho Tatsuo, the Ultimate Librarian, doesn't believe anyone will die, but could he be wrong? (Cmon, it's Dangan Ronpa, and the last line spoils this question.) Join the fellow Ultimates as they battle despair in the City of Despair!
