Hachimitsu Private Academy is a renowned all-girls boarding school located near Tokyo, known for its excellent education and disciplined students. However, with the revision of its most distinctive policy, boys are now allowed to enroll. As a result, five boys have been accepted during the first semester under this new rule, resulting in a ratio of 200 girls to one boy among the student body. The boys, Kiyoshi, Gakuto, Shingo, Andre, and Jo, struggle to fit in and communicate with their female classmates. Desperate for attention, they devise a plan to peek into the girls' baths. However, this plan is thwarted by the infamous Underground Student Council, and the boys are punished by being thrown into prison for an entire month. This marks the beginning of their challenging journey in Prison School, where they must confront their perverted desires and test the strength of their friendships.

The Japanese cast has been universally praised for their work while in contrast the English dub has been heavily criticized for its casting, voice acting and writing.
