From the creator of Danganronpa comes a series that focuses on Guren High, a place where all the biggest and baddest delinquents hang out, so it's the perfect place to recruit some of Earth's mightiest warriors to fight off an alien invasion, right? There seems to be a misunderstanding, though; they're only the heroes in delinquent manga, and that's where recruiter Harmony learned everything she knows about Earth!
