Vol 3
The story of "Prison School" revolves around five male students who are the first to be admitted to the prestigious Hachimitsu Academy, a formerly all-girls school. However, they quickly find themselves in trouble when they are caught peeping in the girls' bathing area. As a punishment, they are sent to the school's underground prison, which is run by the Underground Student Council, a group of authoritarian and sadistic female students. The series combines elements of comedy, ecchi (sexual humor), and a unique narrative that explores the characters' interactions in a highly unusual and absurd setting.
