Ryuji Danma is a delinquent transfer student who becomes obsessed with Eikichi Onizuka after witnessing his violent victory in a street fight. Determined to provoke Onizuka into a decisive battle, Ryuji is frustrated when his rival dismisses schoolyard power struggles, instead spending time repairing a salvaged Kawasaki Z400GP motorcycle with friends. Sakura Yamato, a mutual acquaintance, bridges their divide by revealing Onizuka's carefree philosophy, eventually drawing Ryuji into the group. Their camaraderie is tested when the Skull Gang, a local biker group, steals the restored motorcycle. Onizuka and Ryuji confront the thieves, leading to an intervention by the Running Wild Angels—a prominent gang led by Masaki. Impressed by Onizuka's defiance, Masaki invites the boys to ride with his gang. Ryuji's life takes another turn when he meets Natsuki, a former Running Wild Angels member. After learning he has been locked out of his home, she gifts him her
Honda CBX motorcycle, unknowingly entangling him in her violent past. During a group ride, Masaki recognizes the bike, exposing Natsuki's history with the gang. The conflict escalates when her abusive ex-boyfriend, Akira Nezu—claiming ownership of the CBX—beats her and extorts Ryuji. In a final confrontation, Natsuki stabs Nezu in self-defense and is arrested, though she is later released due to his minor injuries. The story concludes with Ryuji maintaining the CBX in anticipation of Natsuki's return, while Onizuka and the group plan a trip to Tokyo. ==Media==
