Danganronpa: Hope's Academy and Despair's Students

Danganronpa is a murder-mystery visual novel with action elements. The player takes the role of Makoto Naegi, a new student at the prestigious Hope's Peak Academy in Tokyo. Hope's Peak is a high school that only admits the most talented students in the country, whatever their talent may be, but Makoto is unusual even among his extraordinary peers. He was admitted to the academy through a lottery, giving him the title of Super High-school Level Good Luck.

Makoto's first day of school quickly takes a downhill turn when he learns that he and his 14 classmates are locked inside the school, and there is nobody else in the building except Monokuma, a sadistic, talking teddy bear with a black-and-white body. Monokuma offers the students a chance to escape, but only if one of them is able to murder a classmate without being caught. Once a murder takes place, a class trial will be held to decide the guilty party. If the murderer is not correctly decided upon, that student will be able to "graduate" at the cost of everyone else's lives. However, if the students do find the culprit, that single person will be messily executed in an elaborate display.
