A 17-year-old biker runs a gang built on honor in a city that abandoned the concept. When a rookie joins and actually keeps his oath not to fight, the show finds its real battle, not against enemies but against the weight of holding conviction when nobody else is.
Yokohama's streets belong to the bikers. Hiromi Katayama runs the Crazy Babies with an iron fist and a strict code: strength means nothing without honor. When hot-headed rookie Toshi Ikeda joins the crew, he accepts a brutal condition: stay out of fights for one month, or he's done before he starts. It's an impossible task for someone like Toshi, whose fists move faster than his brain. Everything falls apart when Toshi gets pulled into a brawl he never asked for. The punch that lands sets off a chain reaction, drawing the attention of the Dragon Star Crew from Nagoya. These aren't local thugs playing turf wars. They're organized, ruthless, and they want to swallow the entire Kanagawa territory whole. Now Toshi has to survive the consequences of his impulse while proving he belongs in Katayama's gang. The question isn't whether he can fight. It's whether he can earn respect without destroying the family that took him in.
