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.

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.

Kawatani (Hitoshi Ozawa) leaves Kyowakai, naming Himuro (Yasukaze Motomiya) as the 4th Chairman. But with Himuro hospitalized and Tamura (Yoshiyuki Yamaguchi) stuck in Kobe, the leadership seat remains empty. Unease spreads among the executives, and tensions rise between Baba and Hirakawa. The Special Investigation Unit intensifies its crackdown on Kyowakai and Marugami-kai, arresting Kawakami for the hospital attack. Learning the police still can’t reach Shinjo and Komiya, Nakajima heads to the Fujishiro-gumi, but struggles with his failing physical condition. Meanwhile, a new scheme emerges, and drugs once again flood Yokohama. Amid growing chaos, Nakajima makes a critical decision—
