Following the death of acting chairman Baba (Akihiko Kuwata), Kyowakai continues its hunt for Adachi (Atsushi Arai), while the Marugami-kai and the Special Investigation Unit closely monitor their movements. As expected by Himuro (Yasukaze Motomiya), Adachi contacts the Keihin Alliance's Sakagami (Yoshiki Kanahashi), prompting the Yamazaki Ichimon to stake out the group's key locations. Adachi attempts to strike a deal with Sunaga (Masataka Naruse) but flees when it falls through, escaping Teru (Yutaka Kyan) and Ryuji (Tatsuya Kishida). Himuro and Tamura (Yoshiyuki Yamaguchi) then change tactics by kidnapping Sunaga. Meanwhile, reports pour in that Yamazaki faction members are attacking the Keihin Alliance's affiliated groups, leaving everyone to wonder what Himuro's true plan is.

With Baba (Akihiko Kuwata) acting as Kyowakai chairman and Sakota (Hideo Nakano) leading the Marugami-kai, both groups begin a new chapter. Kyowakai finalizes long-delayed executive appointments: Hayashida (Ehara Shu) replaces the retired Nakajima as Shikoku block leader, while Hirakawa (Hitomi Matsuda) becomes Tohoku block leader by Baba’s nomination, easing concerns from Himuro (Yasukaze Motomiya), Tamura (Yoshiyuki Yamaguchi), and Ueki (Daisuke Nagakura). While drinking in Kobe, Baba drunkenly orders Himuro and others to “crush Marugami,” and the remark quickly spreads to Marugami and investigators. Baba then orders a manhunt, but Hirakawa objects and questions why the “Adachi-kai,” a group of delinquent gangs that fled Kyowakai’s control and formed in Tohoku, had been ignored. After being calmed by Himuro, Hirakawa heads to Tohoku to handle the group himself—setting the stage for new tensions involving Baba, Hirakawa, and the Adachi-kai.

Himuro and Tamura rush to rescue Sakagami, now considered a brother, and defeat his captors. Meanwhile, a conflict between Chinese groups and an extremist nationalist resident over a condominium leads to the stabbing death of café employee Han.

Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) return to Kobe, where the Kyowakai executives—still without a clear successor—expect Himuro to become the fourth chairman. Himuro refuses, causing unrest. After meeting Ueki, Himuro decides to respect Kawatani’s wishes and announces only his retirement. At the same time, the Marugami-kai appoints Sakota as chairman following Mita’s death. Meanwhile, Sunaga of the Keihin Alliance approaches Shinjo and Komiya again. Although the information reaches Himuro through Kuroiwa, Himuro rejects it, saying he does not want the Marugami-kai to split. Himuro admits he wanted to make Kawatani the number-one boss in Japan and to unite the yakuza world, but Tamura encourages him to be honest with his own feelings. Elsewhere, the Yamazaki Ichimon learns of Shinjo and Komiya and tries to handle things themselves. During this, retired Kyowakai member Nakajima appears, and his new business becomes the spark for a new conflict.

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.

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.

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.

Yamazaki Ichimon's Summer Vacation!

The Yamazaki family arrives at Akikawa Station and heads into a cicada-filled forest to carry out a mission assigned by Headquarters Chief Tamura. With bug nets in hand, they excitedly begin their search, spotting a praying mantis and later a stag beetle—only to be startled by a sudden “black shadow.” After the scare, they finally find a rhinoceros beetle and celebrate like kids again. Having achieved their real goal of bonding, they spend the rest of the day playing in the river and enjoying a barbecue. Once fully relaxed, the general producer takes on the role of MC, and the group sets aside their characters to enjoy a “real summer vacation” as fellow actors. In the laid-back atmosphere, they share candid memories of joining Unification of Japan (Nihon Touitsu), their fellow Yamazaki members, and their feelings toward the director.

A month has passed since both the Kyowakai and Marugami-kai lost their leaders, yet silence reigns between the two syndicates.

Even the police keep watch nervously, and Kuroiwa (Susumu Terajima) is left uneasy, with no word on Himuro’s survival. Inside the Kyowakai, unease grows as the executive ranks clash over their next move. Meanwhile, Marugami’s Shinjo (Masanobu Sakata) and Komiya (Ryoichi Inaba) see their chance—determined to crush the Kyowakai, now weakened with Nakajima (Yoshimi Tachi), Ryuji (Tatsuya Kishida), and their top three all absent. Amidst this turmoil, Tamura finally regains consciousness. But with both syndicates on shaky ground—can a miracle save Himuro and Kawatani?

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.
