The death of Minami infuriates not only Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi), but the entire Kyowakai organization. As Kyowakai prepares for an all-out retaliation, Chairman Kawatani (Hitoshi Ozawa) orders all executives to stand down and forbids any act of revenge. Meanwhile, in Marugami-kai, Chairman Mita (Shun Sugata), feeling responsible for dragging a civilian like Minami into the conflict, decides to expel Genji (Kuroishi Takahiro) and his men from the group as atonement. Even Senior Advisor Sakota (Hideo Nakano) can’t hide his fury at Genji’s despicable actions. However, Chairman Okada (Yuki Matsumura) of the Okada Union opposes Mita’s decision. While Mita fully understands the risk of triggering a deadly clash with Kyowakai, Okada and others, dissatisfied with Marugami-kai’s stance, launch a surprise attack on the Fujishiro-gumi, a group operating within Kyowakai's territory—igniting an explosive confrontation.
