In 1970s-era Japan, three children, Kazuma Kiryu, Akira Nishikiyama, and his younger sister, Yuko Nishikiyama, are raised together in Shintaro Kazama's Sunflower Orphanage. In the summer of 1980, Yumi Sawamura, a young girl whose parents were accidentally shot and killed during a gang's shootout, joins them in the orphanage. Following a yakuza tradition, the honorable Kazama secretly raises orphans whose parents he has directly or indirectly killed. In return, the children love him as a father and he eventually inducts the teenage Kiryu and Nishikiyama into the Dojima Family, a Tojo Clan affiliate of which he is a senior officer.

Himuro (Yasukaze Motomiya), assistant Wakagashira of Kyowakai, joins Tamura (Yoshiyuki Yamaguchi) and other Kyowakai executives to track down Fukumoto, chairman of the West Japan Mutsumikai, the mastermind behind the assassination plot against Kudo (Hakuryu), Kyowakai’s chairman. Himuro and his men infiltrate the meeting site, preparing to eliminate Fukumoto—but Yashiro, head of the Yashiro-gumi, pretends to cooperate while secretly leaking information to the Kudo-gumi. Seizing the opportunity, Zaizen, assistant Wakagashira of the Kudo-gumi, makes his move—not against Fukumoto, but against Himuro himself. Meanwhile, Kawatani, Kyowakai’s Wakagashira, is delivered a shocking revelation by Kudo.

After bringing the Chubu region under his control, Himuro (Yasukaze Motomiya) faces a new upheaval when Akimoto (Sho Aikawa) of the Marugami Alliance is suddenly incarcerated. This triggers Takishima (Masahiko Tsugawa), chairman of the Marugami Alliance, to announce his retirement. Mita (Shun Sugata), the executive director, is appointed as the second chairman of the Marugami Alliance. However, Tsurumi (Mikio Osawa), head of the Tsurumi-gumi and deputy executive director, fiercely opposes the new leadership. Meanwhile in Hiroshima, Fukumoto (Keiji Matsuda), who previously failed to assassinate Kudo (Hakuryu), sets his sights once again—this time moving to eliminate Himuro.

Himuro (Yasukaze Motomiya), wakagashira assistant of Kyowakai, and Tamura (Yoshiyuki Yamaguchi) eliminate Fukumoto, chairman of the West Japan Mutsumikai, in a chaotic firefight. Himuro’s nephew Sugaya is killed protecting him, leaving Himuro devastated. Taking responsibility for Zaizen’s assassination plot, Kudo retires. After absorbing the West Japan Mutsumikai, Kyowakai enters a new era under third chairman Kawatani (Hitoshi Ozawa). In the east, Takishima retires as Marugami-kai chairman and Mita becomes second chairman, leaving Kyowakai and Marugami-kai as the two dominant forces. Munakata (Takanori Kikuchi), assistant to the Marugami-kai chairman, is released from prison and reunited with Kawatani and Himuro, recalling their shared past. As Kyowakai restructures, Kawatani delivers a shocking message to Himuro.

Promoted to assistant Wakagashira of Kyowakai, Himuro (Yasukaze Motomiya), along with Tamura (Yoshiyuki Yamaguchi), who has also risen to an executive position, heads to Kumamoto to back the Aso and Kirishima families, the Kumamoto faction that broke away from the fiercely contested Kyushu Shiseikai succession struggle. During their stay, a hitman strikes—Kenta is shot while shielding Himuro and is left in a critical, unconscious condition. Meanwhile in Kanto, Takishima (Masahiko Tsugawa), chairman of the Marugami Alliance, retires, and executive director Mita (Shun Sugata) becomes the second chairman. However, Tsurumi (Mikio Osawa), head of the Tsurumi-gumi, strongly opposes the decision—only to find himself targeted by would-be assassins as well.

Having been appointed Wakagashira, Himuro Renji (Yasukaze Motomiya), head of the Yamazaki-gumi of Kyowakai, moves forward under the Kyowakai crest alongside fellow newly promoted assistant Wakagashira Tamura (Yoshiyuki Yamaguchi), aiming for the unification of the Japanese yakuza world. Meanwhile, a dispute breaks out in Aomori between members of the Kyokuzankai in Tohoku and the Kanto-based Marugami-kai, resulting in the death of a Kyokuzankai member. The incident casts a dark shadow over both sides, pushing tensions to the brink of conflict. Seeking to avoid an all-out war, Kyokuzankai executive Ueki (Daisuke Nagakura) asks Himuro to mediate. Himuro enters negotiations with Munakata (Takanori Kikuchi), assistant to the Marugami-kai chairman. As yakuza across Japan watch closely, what decision will Himuro make…?
