剧情简介：The Kyowakai-Shintokai War came to a close with the disbandment of the Shintokai. While Kyowakai’s second-generation chairman, Kudo (Hakuryu), pushes forward with his ambition to unify Japan’s underworld, Kawatani remains stubbornly indecisive. Meanwhile, in Nagasaki prison, Tamura (Yoshiyuki Yamaguchi) is approached by a man bearing a ceremonial sake cup from Mikami… At the same time, Himuro (Yasukaze Motomiya) enters Kawasaki Prison, only to come face-to-face with his old rival, Akimoto (Sho Aikawa). With former Shintokai member Sugamoto joining in, a fierce power struggle erupts behind bars, where the stakes are nothing less than the yakuza crests themselves.
