Danganronpa revolves around fifteen students who are trapped in the school under the control of a sadistic monochromatic bear named Monokuma. They are forced to live a communal lifestyle together under a set number of rules for the rest of their collective lives, although it is possible to "disrupt the peace" in order to escape. In order to do this, a student must "graduate" from the school by murdering a classmate. After a body has been discovered, the rest of the students must work together to discover the culprit, who is known as the "blackened", while the innocents are on the side of the "whitened," playing off Monokuma's monochromatic color scheme. If the murderer can deceive the rest of their classmates, they alone will graduate and escape the school while the rest of the students will be punished through execution. However, if the classmates uncover the true culprit, then the culprit alone will be punished with a gruesome execution while everyone else remains unharmed.
