Souma, who had always experienced peaceful classrooms, is bewildered by the delinquent atmosphere in his new class. He prefers to keep his distance to stay safe and has a strained relationship with his family. Souma's sole aim is to quietly graduate and leave home to start working, treating school as a means to that end. However, a certain action draws him into an unexpected problem, disrupting his plans for a trouble-free graduation.
