Unification of Japan 74

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.

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.

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 month has passed since both the Kyowakai and Marugami-kai lost their leaders, yet silence reigns between the two syndicates. With Chairman Mita (Shun Sugata) gone, the Marugami-kai remains leaderless, while the Kyowakai reels not only from the loss of Kawatani (Hitoshi Ozawa), but also from Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi), both lying in critical condition. 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?
