Bloodstained Clan of Honor

In 1965, Kensaku Gunji is elevated to lead the Hamayasu family in the Port of Yokohama, replacing the imprisoned acting head Tetsuji Kuroki. His ascent comes amid a broad police crackdown on criminal organizations that had thrived in the postwar era. Gunji's new authority sets the stage for pursuing the warehousing deal and the eviction of the slums.

Onuma's arrest under the Port Labor Act halts shipping and shakes the local underworld economy. Iwakiri, the head of a rival group, asks whether Gunji wants to exit the shipping business and proposes seizing warehousing rights to Oriental Heavy Industries' new factory complex. To do so, Gunji is pressured to clear out the slums that stand on the land.

Gunji agrees to clear the slums to secure the warehousing deal, but Kasama Tsutomu chooses to resign rather than witness the eviction of the elderly residents. He refuses to quit and pledges to take charge of the eviction instead. The decision deepens the rift within Hamayasu and foreshadows further confrontation.

When Gunji attempts to talk with the slum residents, they hurl objects, including a dead cat, signaling their defiance. Kasama's father scolds his son for joining the yakuza and now pushing out his own people, while his mother laments the consequences. Old ally Hayami, who had left the slum twelve years earlier to box, returns aboard the SS Black Dragon to defend them.

By the next morning, Hamayasu and Iwakiri forces move to destroy the slum's livestock and suppress the inhabitants. The residents barricade themselves inside, gaining a defensive but income-sapping stalemate. Three Kyushu miners arrive, trying to pose as locals to secure Daimon Construction’s leaving payments.

Tetsuji Kuroki is released from prison and returns to the Hamayasu. He visits a former lover working as a bar waitress who reveals she has waited five years, but he resists rekindling their relationship. The encounter underscores personal tensions behind the gang war.

Hayama accepts money from Daimon and allows them into the slum to pressure a family into selling by force. The collaboration marks a sharp escalation in Daimon's influence over the eviction drive. Gunji and his men brace for a brutal campaign.

The next day Daimon soldiers arrive at the slum with the deed of sale and beat back resistance. Gunji receives a letter—Kasama's severed pinky—an apology for acting on his own and an ominous sign of the orders from above. The attack demonstrates the Daimon group's willingness to use extreme violence.

Kasama storms the Daimon Construction office intending to kill Daimon's boss, but he is captured. In a final act, he bites off his own tongue and dies, a brutal testament to the desperation of the conflict. Gunji and others are left to reflect on the costs of loyalty.

Daimon and the enforcers demand a 50 percent share of the warehousing rights to overlook the attack; Kuroki arrives to back Gunji and fights off Daimon, killing Iwakiri in the process, but is fatally wounded. He dies with thoughts of the waitress, illustrating the personal costs of the war. The cycle of vengeance tightens its grip on Yokohama.

The night brings confusion as Daimon-backed forces push into the port, and the police arrest Hamayasu members after a stabbing. The crackdown deepens the community's fear and cements the rift between the factions. Gunji is taken away as news of Kuroki's death spreads.

The waitress pays Gunji's bail, and they visit Kuroki's grave together, signaling fragile human bonds amid ongoing violence. The moment hints at a fragile alliance forming against Daimon as the power struggle continues. Despite the personal ties, the conflict shows no easy resolution.

Realizing they've been played like marionettes, Gunji and Hayami join with others to disrupt Daimon's groundbreaking ceremony for the new factory complex. They stab Daimon to death but are themselves killed by other Daimon gang members, illustrating the cycle of vengeance. The attempt fails to halt Daimon's plans and costs both men their lives.

The Oriental Heavy Industries factory complex is completed the following year, reshaping the landscape of Yokohama. Japan's GDP soon becomes the second-largest in the world, surpassed only by the United States, underscoring the era's economic consequences amid violence.
