The 6 strongest delinquents clash today, putting their pride on the line!
The setting is Kokurei High School, a private school in a rough neighborhood.
The school is divided into two major factions: the male-dominated "Mad Dog Union" and the female-dominated "Crimson Sisters," who are constantly locked in a power struggle.
While all six are delinquents, they are the type who despise bullying the weak or playing dirty. Each values their own sense of "honor," and despite being enemies, they acknowledge each other's strength.
Beyond factional skirmishes, the story features conflicts with local street gangs, school events, and ridiculous daily rivalries.
They may be at each other's throats during a fight, but in daily life, they are strangely close or show unexpected sides of themselves—a hot-blooded and comedic delinquent youth story.
