Yokohama Meibutsu: Otoko Katayama-gumi!

Yokohama has become a hub for unruly biker gangs. The Crazy Babies, led by 17-year-old Hiromi Katayama, are known for their strength and strong moral code. A new recruit, Toshi Ikeda, joins the gang and promises not to fight for a month as part of his probation. If he breaks this rule, he will lose his chance to stay. Ikeda's impulsive nature leads him into a conflict, unintentionally starting a dispute between Kanagawa gangs and the Nagoya-based Dragon Star Crew, who seek to expand into Kanto. Katayama must now protect Yokohama from the growing threat.
