About

Class 3-C is full of students who are academically gifted but have the worst behavior imaginable. To set them straight, a new group of teachers has arrived—and every single one of them is a former professional assassin. The school life of these delinquents, who have no idea about their teachers' pasts, and the ex-assassins hiding their true identities, begins now.

Who will be the first to break in this school—?
