This RPG is based on the events of "Danganronpa 2: Goodbye Despair", where the students of class 77-B of Hope's Peak Academy are trapped in a killing game after passing out and waking up on Jabberwock Island. It was supposed to be a school trip, but now the only way to escape is killing someone and getting away with it by not being voted as the culprit in the class trials. The students are provided with a personal cottage at Hotel Mirai and a Monopad. They don't know this is a fake reality.
