Successful school student Riki Fudou leads a double life in organized crime. With his gang of underage assassins, including five-year-olds with hand guns and teenage strippers who shoot deadly darts, he aspires to take over the criminal affairs on the entire island of Kyushu. Fudoh's motivations are not just a lust for power. As a child, he witnessed the grisly murder of his older brother at the hands of his yakuza boss father. Buckets of blood flow when Riki and the kids start an assassination campaign against the top figures of the local yakuza, with his father as the ultimate goal.

Takashi Miike's film FUDOU was based on this manga.
