Danganronpa: The Animation Volume 1 - Spike Chunsoft

Each year, the elite Hope's Peak Academy selects only the most gifted and talented students to enrol - plus one ordinary student, chosen by lottery. Makoto Naegi was that lucky person - or so he thought! When he shows up for class, he finds the elite students are a bizarre cast of oddballs under the ruthless authority of a robot teddy bear principal, Monokuma. The bear lays down the school rules: the only way out of Hope's Peak is to not only murder another student. but get away with it, as every murder is followed by a tribunal featuring the surviving students!
