Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) returned to Tokyo to confront Okada (Yuki Matsumura). However, waiting for them was a notice of succession from the Hasekai, which was supposed to be under the Kyowakai's control. Upon learning that Okada’s faction had ties to the Hasekai's new successor, Himuro immediately severed ties, bringing the direct showdown between the Kyowakai and Marugami-kai closer. Meanwhile, Reiko (Reira Arai), who had been hiding with Genji (Kuroishi Takahiro), continued living in hiding, harboring distrust towards Genji and others. Despite this, she remained focused on her vengeance against the Kyowakai. While Himuro and the others tried to clear up Reiko's misunderstanding for Minami (Rin Asuka), Reiko refused to listen. Gradually, she became more involved with Okada’s faction, who were willing to use anything for the war against the Kyowakai.

A sudden notice of succession from the Hasekai arrived from the Marugami-kai. Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) were furious and stormed into the ceremony. Mita (Shun Sugata) saw this as a declaration of war and vowed decisive action. The police, led by Matsumiya (Gento Hongo), ramped up surveillance on the rising tension between the Kyowakai and Marugami-kai, leading to the arrest of Teru (Yutaka Kyan) and Saito (Katsuya), escalating the crisis. Amid rising tension in the Kyowakai, Nakajima (Yoshimi Tachi) sought revenge for Shoji’s death. Concerned about Minami (Rin Asuka) due to Reiko’s (Reira Arai) involvement, Himuro and the others were encouraged by Kawata (Hitoshi Ozawa) to proceed. Himuro’s plan set up a clash between Kuramoto Kogyo and the Keihin Rengo-kai. Though it initially went smoothly, Jun (Goro Washida) and Chosaku (Keishi Kawaguchi) interfered, creating new complications.

Himuro (Yasukaze Motomiya) launches an all-out assault on the Okada Union, led by Okada (Yuki Matsumura) of the Marugami-kai. While the police suspect Kyowakai’s involvement in the string of attacks, the group feigns innocence. Acting on Kuroiwa’s (Susumu Terajima) tip, Special Investigator Matsumiya (Gen Hongo) summons Okada, but the tense exchange nearly turns explosive. Outside the station, Himuro and Tamura (Yoshiyuki Yamaguchi) lie in wait—until they spot Kawatani (Hitoshi Ozawa) watching too. Just before they act, they stop him. Kawatani walks away, leaving them with: “Take care of the Kyowakai.” As tensions escalate between the Kyowakai and Marugami-kai, Ryuji (Tatsuya Kishida) remains unconscious. Burdened with guilt, Nakajima (Yoshimi Tachi) secretly prepares for revenge. At last, Kawatani and Mita (Shun Sugata) face off for a final showdown.

With the release of Uesugi Yoshitake approaching, the Toyokai receives an assassination threat against him. The leadership raises security, while Munakata Seizo restructures his group—naming Sakai Atsushi as underboss and Murata Kunio as his aide. Meanwhile, Sawamura Ryuichi and Soma Kunihito try to settle a dispute involving old comrades, but…

The Toyokai leadership fends off attackers, but the assailants’ identity and motives remain unclear. Suspecting the rival Teito Union, Uesugi grows wary. Assigned to Uesugi’s crew, Soma digs into their networks—uncovering traces of former Teito members like Sudo Reiji, who has fled overseas.

Himuro (Yasukaze Motomiya), Tamura (Yoshiyuki Yamaguchi) and others discover Ruby's true identity and discover a large amount of firearms and shabu. He tells Sahara (Takayuki Kanema), a member of the special investigation team, that the series of incidents was not the work of the Kyowa-kai and the Marukami-kai, and advises him to investigate the relationship behind the incident. Himuro suspects that there is a mastermind among the police, but Sawara is similarly suspicious of Matsumiya (Gen Hongo) and others. Meanwhile, the police begin to arrest Mita (Shun Suda).

Nao (Nishikawa Ayano) is the wife of Ota (Ryota Matsushima), a legal advisor to the Seagull Victims Association, who has been captured by the religious organization World Seagull Church. Tamura (Yoshiyuki Yamaguchi) enters the cult's facility alone to rescue his girlfriend Nao. Himuro (Yasukaze Motomiya) notices that Tamura has boarded the vehicle and heads to the facility alone as well. At the direction of the founder, Takahara (Nishikawa Mizui), the two of them fight against the believers who come armed with weapons, but they are unable to stand against the overwhelming numbers and are captured.

The incident occurred without any warning. A member of the Kyowakai was shot in Kyoto. This shooting incident, which took place in Kansai—the very region Kyowakai was supposed to have unified—sent shockwaves through Himuro (Yasukaze Motomiya) and his men. As Himuro and Tamura (Yoshiyuki Yamaguchi) hurriedly prepared for an emergency executive meeting in Kobe, they were stopped by Kuroiwa (Susumu Terajima ) from the Hachiwari Police Department, who came to visit the Himuro-gumi. According to Kuroiwa, Matsumiya (Hongo Gen) from the special investigation unit believed that this incident was an internal conflict within the Kyowakai. Himuro and Tamura learned that the reason for this suspicion was a clash between Hayashida (Shu Ehara) and Kamiyama (Naoki Yamazaki) over a land redevelopment project in Kyoto. Determined to get to the bottom of the matter, they set out for Kyoto. In that area, various people’s emotions and interests were intricately intertwined…
