I’m currently playing a game called Danganronpa. It’s a very unique game (or visual novel) about 15 students who are trapped in an abandoned school by a bear-like psychopath. The only way for them to be freed is by killing at least one person and getting away with it.
Unlike other battle royale stories which revolve around being the last one to survive, in this story, you just have to kill one person without letting any other students know you’re the culprit. After a murder takes place, there will be a period of time for all the students to investigate the crime scene and search for all the evidences. Then, the ‘class trial’ starts.
