Crimson 5

Synopsis

Guren High is 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! Note: This series is published in Comic Gene, a shoujo magazine which is marketed as "shonen manga for female readers". Please do not edit the demographic to shonen or seinen.
