The relationship between the Mikami-gumi and the Shintokai led by Ueda (Jiro Okazaki) has deteriorated due to factional disputes caused by Kudo (Hakuryu), the second generation of Kyowakai. At that moment, Kawatani (Hitoshi Ozawa), the benefactor of Mikami-gumi Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi), is shot. Tamura, who learned that it was the work of the Shintokai, infiltrated Ueda's residence alone and executed Ueda's assassination. At the same time, Kawabata (Tatsuo Umemiya), the leader of the Kansai Shisei group, begins crushing Himuro and the Mikami gang, who are racing to unify Japan.
