Hachimitsu Academy, known for its strict academic standards and even stricter school code, is making a giant change this year. In the first time in school history, they are allowing boys to be admitted.

As Fujino Kiyoshi starts his first day at Hachimitsu Academy he is shocked to find out that there are only four other guys in the entire school, making the ratio of girls to boys 200:1. And to their dismay, not one of the thousand girls will talk to them or even acknowledge them. But Kiyoshi and the guys are about to find out about the shadow student council that has been threatening the female students about interacting with male students.
