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.

Kyowakai acting chairman Baba (Akihiko Kuwata) is attacked, and despite Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) rushing to the scene, the assailant escapes. The Keihin Alliance and Marugami-kai suspect Hirakawa (Hitomi Matsuda), who had poor relations with Baba, but based on witness Reiko’s (Reira Arai) description of the attacker, Himuro identifies a likely suspect. Ordering Reiko to stay silent and refusing police involvement, Kyowakai launches its own manhunt. As Baba remains in critical condition and suspicion toward Hirakawa grows among investigators and Kyowakai executives, Himuro quietly burns with thoughts of revenge.

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.

The eighth 'Daimon Graveyard' film.

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.
