Loan shark Tsukasa does good business serving women-in-need, but he struggles to recoup his loans when a shrewd yakuza uses his idea against him.

Tachibana Shuji (Kazuki Namioka), leader of the Tachibana-gumi under the Anzai-gumi, is a unique figure—a university graduate turned yakuza. Known as the youngest leader in the Anzai-gumi, he was inspired by Anzai Takashi (Koichi Iwaki), the group's boss, and chose the yakuza path, aiming to be like him. Trouble arises when a thug from the Otsuru Family deals drugs in Anzai-gumi’s territory, violating their rules and sparking conflict. As tensions with the Otsuru Family threaten war, internal rifts form within the Anzai-gumi. Meanwhile, Anzai is set to be released from prison after 13 years, setting the stage for a dramatic showdown.

Himuro and Tamura put an end to the suffering of Munakata, the leader of the Fujishiro-gumi of the Marukami-kai, and expanded the Kyowa-kai to the Kanto region, but soon after, they receive news of Munakata's suicide. When Himuro saw the suicide note, he became suspicious and concluded that it was the work of Tsurumi of the Marukami-kai, who was the first to discover it. The conflict between Himuro and Tsurumi becomes even more intense.

Kyowa-kai Himuro and Marukami-kai Tsurumi are in a tense state of conflict. The conflict between the two groups intensified due to internal disputes between the Yokohama and Fujishiro groups. Meanwhile, Himuro's brother Akimoto, a member of the Marukami-kai leadership, dies of illness. With the deterrence of East-West conflict gone, tensions between the Kyowa-kai and the Marukami-kai reach a climax.

Himuro and Tamura of the Kyowa-kai discover that the conflict with the Marukami-kai involving the Yokohama Fujishiro-gumi is a secret maneuver between the Chinatown mafia and the half-grey group Kobura. Having discovered that they have a common enemy, the Kyowa-kai and Marukami-kai formulate a joint strategy, but Himuro and Tsurumi of the Marukami-kai are at odds over the dead Ryuji Munakata.

Himuro, who promoted Kawakami, the fourth Yamazaki-gumi advisor, to direct advisor to the Kyowa-kai, solidifies his intention to exchange sake as the Fujishiro-gumi's spiritual representative. Meanwhile, Himuro heads to Toryukai in Ibaraki to find out that the land being redeveloped by Hirokawa Kanko, which is affiliated with Itonaka Construction, is being handed over to a company affiliated with Marukami-kai.
