Adapted from the very popular comic book
Hachimitsu Academy is a private boarding high school that used to be all-girl but is turning coed this year.
Only 5 boys have been admitted and are excited just thinking about what school life will be like at Hachimitsu with over 1,000 girls attending. But one day, when they get caught peeking into the girls’ bathroom, they are forced to spend a month in the “Prison” by the “Secret School Council,” a committee that rules the school with an iron fist.
While the boys try various means to free themselves, the “ Council” will go to any length to drive the boys into withdrawing from school.
