Japan Organized Crime Boss

The Danno Organization grows beyond its Osaka base as Boss Danno and Chief Executive Tsubaki consolidate power in the post-war years. They aim to project influence across Japan, drawing the attention of rival families. The expansion lays the groundwork for the later conflict with the Tokyo Alliance and Yokohama factions.

To counter Danno's expansion, the Tokyo yakuza families form the Tokyo Alliance and appoint Boss Yato as chairman. They coordinate proxy actions against Danno's interests. This alliance marks a new theater of conflict in the region.

In Yokohama, the boss of the Hamanaka Family commits fealty to the Danno Organization, signaling a shift in regional power. The Hamanaka affiliation strengthens Danno's grip in the area. Rival forces start planning a proxy war to pressure Yokohama.

Hamanaka's right-hand man, Tsukamoto, is released from prison after eight years. He discovers that his wife committed suicide, an event that hardens his resolve. The personal loss intensifies the looming gang conflicts.

Shortly after Tsukamoto's release, the Hamanaka boss is killed by explosives hurled by hitmen from the Sakurada Family. With his dying breath, the boss passes control to Tsukamoto and urges him to reject the Danno Organization to defend Yokohama. Tsukamoto inherits leadership under the shadow of a violent proxy war.

A funeral is held for the fallen Hamanaka boss. Chairman Yato and Boss Danno visit to pay respects, signaling the ongoing rift between factions. Kamiyama, the retired Hamanaka boss, offers to assist Tsukamoto as an unofficial advisor to navigate the conflicts.

Tsukamoto wishes to call a truce with the Sakurada Family and end his family's oath to Danno, but the pressure from his men leads him to decide to kill Boss Sakurada. His choice reinforces the hardline stance within Hamanaka and escalates the cycle of vengeance.

Senior Hamanaka officer Kazama takes on the enmity by personally murdering Boss Sakurada. He returns home mortally wounded and dies, his death underscoring the brutal cost of the feud. Tsukamoto's plan is further complicated by Kazama's actions.

Tsubaki warns Tsukamoto to stay with the Danno Organization and that opposing him could mean dying in the gutter. The warning reveals the dangerous politics surrounding leadership choices. Tsukamoto's resolve remains tested as he weighs loyalty against personal code.

Kazama's sister, left with no protector, finds a new ally in Tsukamoto. He promises to help her and, through shared hardship, they develop a relationship. The personal bond adds emotional stakes to the ongoing gang conflict.

The Hokuryu Kai, led by Miyahara, is expelled from the Tokyo Alliance for disrespect and code violations. In response, Danno convinces Miyahara to swear loyalty to Tsukamoto and mobilizes them against the Sakurada Family. The conflict escalates as loyalties shift and clashes intensify.

During the confrontation, Taki is captured, and Tsukamoto confronts Miyahara at a nightclub. He refuses to fight, and Miyahara, aiming to avoid a full-scale war, allows Taki to leave. Kazama's sister tends to Tsukamoto's wounds, and they grow closer.

Ooba, a resentful former boss, carries out an attack on Boss Danno during a confrontation with Danno's circle. Danno is wounded along with an American tourist who dies later; Ooba is killed and his wife dies in the pursuit. The Hamanaka Family rescues Ooba's wife, while the police later denounce Tsukamoto's role.

Following Bokudo Kita's push for reconciliation and a Tokyo Alliance-backed truce, Miyahara is ambushed and killed by alliance forces. Tsukamoto is arrested, but the Danno Organization seizes the initiative and delivers a surprise attack that devastates the Hamanaka Family. Tsukamoto is eventually released.

Disgusted by the truce, Kamiyama lets Tsukamoto approach the ceremony site where Danno is to be reconciled. Tsukamoto stabs Danno and Yato, seeking to avenge the honor of his clan, while Bokudo survives. A rival yakuza shoots Tsukamoto; he bleeds out, having upheld his family's honor.
