Revenge Game

A girl named Matsui Sakura receives an invitation to a "Revenge Game" and attends, only to be locked in a dormitory-style building with four classmates. The game is orchestrated by Saionji, a wealthy student who was severely bullied, and now seeks retribution by killing one of his former tormentors each day. Sakura, an orphan who is quiet and isolated, is unsure why she was invited, suspecting her inaction during others' bullying may be the reason. Unlike the others, who were either kidnapped or tricked into attending, she was directly invited. The ultimate goal of the game remains unclear.
