Monokuma is the headmaster of hopes peak academy. He brought all of the 16 students to kill each other! Just for his own fun! He claims to be sweet but he is obviously sarcastic when saying that. He follows rules strictly but is very sly. He often takes his anger out on Monomi (his sister).
Monomi is a sweet bunny, she was a teacher and hopes peak academy and she brought the students to the island, however monokuma ruined the trip and turned it into a killing game! Or was it the plan all along?
