The class's delinquent leader. Blonde hair, piercings, and rides a moped. Basically ignores all school rules.

He keeps underclassmen lackeys around along with his classmates. He spends most of the class time walking around.

A delinquent. The class factions are mainly split between the Yamamoto and Sato factions. He and Yamamoto are fierce rivals.

A kind-hearted delinquent belonging to the Sato faction.

A member of the Yamamoto faction. A flashy, high-energy delinquent.

Leader of his own small circle. Actually the kindest of the bunch. He looks like a delinquent, but he's really just an extroverted social butterfly.

Part of Yamamura's circle. Unable to keep up with the heavy delinquent atmosphere, he secretly hangs out with Yamamura. However, he manages to stay on good terms with the others too.

Leader of the Harimoto faction. Actually the strongest fighter, but no one knows it. He isn't a delinquent, but he once beat a mobster half to death single-handedly.

Partnered with Nemoto. An "intellectual mobster" (according to Nemoto). Usually mild-mannered, but even Nemoto says he's the scariest person when angered.

Partnered with Sekine. Extremely intelligent and maintains excellent relationships with everyone in the class. Just as terrifying as Sekine when he loses his temper.

Hamada the Straight Man. Very funny and the class mood-maker. However, he is also an incredibly strong fighter.
