Prison School

Hachimitsu Academy, a school known for its demanding academics and strict rules, admits boys for the first time in its history. When Fujino Kiyoshi arrives, he discovers that only four other boys have enrolled among a thousand girls, leaving a ratio of 200 girls to every boy. The five boys are dismayed when none of the girls will speak to or even acknowledge them. They soon learn that a shadow student council has been threatening the female students to keep them from interacting with boys.
