Guren 5

A mysterious girl from a devastated planet suddenly appears at a high school infamous for housing the worst delinquents. Her unexpected arrival sets the stage for chaos, as she offers an enigmatic reward to whoever can prove themselves as the most powerful fighter in the entire student body. Driven by the allure of this special prize, the school's toughest students plunge into a massive, campus-wide brawl to determine who truly reigns supreme. Raku Itsushima arrives at school slightly late, only to walk straight into the middle of this violent upheaval. Rather than avoiding the conflict, he finds himself drawn into the escalating war that has consumed his classmates. However, Raku’s involvement is not merely about claiming the mysterious girl's reward or establishing dominance over the other delinquents. His true motivation runs far deeper, transforming what begins as a chaotic schoolyard battle into something much greater. As tensions rise and fists fly, Raku embarks on a critical adventure with a singular, monumental goal: protecting Earth itself from an unknown threat tied to the girl's ruined homeworld.
