Enredo

15 elite high school students are trapped in school and forced to participate in a sadistic killing game - Either remain in confinement forever or murder someone without being detected in order to escape, but risk death if they are caught.

Danganronpa takes place at an elite high school named Hope's Peak Academy, which accepts talented "Ultimate" students of the highest caliber in various fields each year. Makoto Naegi, a fairly optimistic but otherwise average student, is selected in a raffle and chosen to enroll into the academy as the "Ultimate Lucky Student". However, when Makoto arrives at the Academy, he loses consciousness and wakes up locked inside the school, where he meets fourteen other newly picked Ultimate students who are in the same situation as him. A sadistic, remote-controlled bear named Monokuma appears before them, telling them they will be imprisoned in the academy for the rest of their lives, and that they will be put to death if they violate any of the school's rules. He states that there is only one way that a student can leave the academy: murder another student and avoid being identified as the culprit.

A group of 15 elite high school students are gathered at a very special, high class high school. To graduate from this high school essentially means you'll succeed in life, but graduating is very difficult. The school is presided over by a bear called Monokuma, and he explains to them that their graduation hinges around committing a murder. The only way to graduate is to kill one of your classmates and get away with it. If the other classmates discover the identity of the killer, the killer is the only one executed. However, if they fail to catch the killer, only the killer graduates and the others are annihilated. Which of the 15 will survive the bloodbath to come?

15 students, all of them the best at what they do, are forced to live together in a private school, trapped by the sadistic mastermind. The only way out is to kill someone and get away with it. If someone is killed, they all have to work together to deduce the correct culprit.
