Onani Master Kurosawa

Kakeru Kurosawa is a withdrawn junior high student who avoids social interaction and looks down on his peers. He keeps a private habit: visiting the seldom-used girls' restroom on the third floor after school for personal gratification. His routine is disrupted when a classmate, Aya Kitahara, nearly catches him. This encounter initiates a story involving threats, mistreatment, retaliation, emotional pain, and eventual personal growth. A secondary narrative is also included.
