A Rhythm Thief and Dagan Ronpa crossover. With the help of Octoryan, we've decided to make this crossover. Marie, Rachael, Charlie, Michel and the others are stuck in a mutual killing game. With forbidden actions, some may not be able to do certain things. If they do, they will be injected with poison. And for Monokuma, a mastermind that is responsible for all of this will be revealed after a few trials.
