Proper Japanese Title: 私立極道高校
Originally serialized in Weekly Shonen Jump. Though only one volume was released originally, the magazine had serialized enough content for four tankobon before it was cancelled. This series was notable for being Akira Miyashita's first serial in Weekly Shonen Jump where he would later be one of the defining creators of the Golden Age of Jump. Decades later (in 2011/2012), this series was revived through Nihon Bungeisha and Shueisha finally reprinted the entire series.
Notably, this was one of the only times in Weekly Shonen Jump's history that a series was cancelled due to controversy rather than losing popularity or the author wrapping things up (this was the reason the entire series wasn't originally collected even after it was cancelled).
