After a nationwide yakuza conflict ends, Kyowakai enters a new phase under Wakagashira Himuro Renji (Yasukaze Motomiya), strengthening its territories across Japan. Assistant Wakagashira Tamura (Yoshiyuki Yamaguchi) moves the Kawatani-gumi headquarters to Osaka to secure western Japan. In Tohoku, many groups join the Kanto-based Marugami-kai led by Mita (Shun Sugata), but Hirakawa (Hitomi Matsuda) of Shinyukai refuses and instead joins Kyowakai. Seeking revenge, Marugami-kai Vice Director Tsurumi (Mikio Osawa) prepares for conflict. Within Kyowakai, Wakagashira-hosa Kijima becomes isolated, while former Kudo-gumi members plot a return by targeting Chairman Kawatani (Hitoshi Ozawa). Meanwhile, Ryoichi (Shin Koyanagi), son of the first Gonda-gumi boss, is released from prison and placed under Himuro’s care—bringing new uncertainty.
