This series, about a school, broke various taboos, using subjects as voyeurism and sex. As the manga continued its serialization, it garnered more and more controversy from parents. As a result, the Jump Editorial Dept. decided to cancel the serial. Nagai, in response to the controversy, decided to end off the manga with the very infamous "Harenchi War" (Shameless War) arc and a massacre in which all the characters died.
