This is the legendary Go Nagai's breakthrough work. Harenchi Gakuen is an elementary school whose teachers and students are all perverts. Boys peep girls changing. Girls pull up their skirts and show off their panties. Actually, it's not as evil as you imagine. They're like cubs playing together. It's only pre-school eroticism, nothing sexual. In spite of that, Harenchi Gakuen became a sensation. Parents, teachers, and politicians hysterically attacked the comic's immorality. Finally the magazine publisher decided to cancel it.
Was one of the first works of the legendary Go Nagai, and has left an indelible mark in the world of manga, are considered the first ecchi manga in history, and also considered by some as the first lolikon manga or the first modern hentai manga. History shows us the events and daily trips of elementary students, in a lewd school and governed by extravagant teachers . While the focus of this story is comedy, Nagai made use of certain bizarre elements that resembled eroticism portrayed in a bizarre way in teachers and students with the constantly conflict of shame and embarrassment. The concept of the work (at least the first stage ) can be summarized in the courage, nobility and innocence of young players, trying to do justice against evil and wickedness adults.
