Kobe in the Showa era. Within the Hamasei-gumi, a branch of the Yamaga-gumi, there were two men known for charging ahead purely on emotion—the Okanaka brothers. The older brother, Hirokazu (Hitoshi Ozawa), and the younger, Ryuji (Yasukaze Motomiya), shared the same family crest, but if something rubbed them the wrong way, they wouldn’t hesitate to beat even their own allies half to death. One day, Ryuji causes trouble by wrecking a gambling den run by the Umeda-gumi, leaving him with no place left in Kansai. Hirokazu takes responsibility for the incident and leaves the yakuza world, becoming a civilian… but fate is far from done with the brothers.
