Onani Master Kurosawa

Fourteen-year-old Kakeru Kurosawa is an antisocial junior high school student who looks down on his classmates—but beneath his superiority complex is a hopeless young teenager who uses masturbation as a pastime. Using erotic thoughts of his female classmates as stimulus, he locks himself daily in a seldom-used girl's bathroom at school to do his dirty deed. One day during class, Kurosawa witnesses the popular girls bullying the timid Aya Kitahara. Although not one to be riled over such matters, he decides to deliver retribution with his own hands. In a daring move, he steals the uniforms of the bullies and dispenses his "white justice" over them. Although satisfied with his exploits, Kurosawa's troubles are only just beginning. While going about his daily routine, he is suddenly confronted by Kitahara, who identifies him as the culprit behind the uniform incident, and blackmails him into terrorizing the other girls in the class the same way he dealt with her bullies. Left with little choice, Kurosawa agrees, and thus begins a coming-of-age story that deals with consequences, bullying, and people's ability to change.
