Yoshizane Satomi rules as patriarch of the Satomi clan in 15th-century Awa Province, assuming leadership amid crisis when a rival clan assaults his famine-stricken domain. Plunged into a desperate siege, he mockingly vows to wed his daughter Fuse to the family dog Yatsufusa should it deliver the enemy general’s severed head. When Yatsufusa fulfills the gruesome feat, Yoshizane honors the pledge, bound by duty yet aware of the curse Tamazusa invoked upon the clan after they executed her husband, Sadakane.

Fuse withdraws to a secluded cave with Yatsufusa, preserving her chastity through devout Buddhist practice until Yoshizane discovers her mortally wounded by a retainer’s stray arrow. Her ritual suicide unleashes eight spiritual beads imbued with Confucian virtues, which scatter across the land to incarnate as the Eight Dog Warriors. Yoshizane’s oath and Tamazusa’s curse thus intertwine, forging the warriors’ destiny to redeem the clan’s honor.

Though Yoshizane once expanded the Satomi territories by overthrowing Sadakane and securing alliances, his fateful jest and its supernatural repercussions eclipse these political triumphs. A figure of paradoxical legacy, his choices—steeped in desperation and obligation—ignite both the clan’s downfall and its path to resurgence. His prominence fades after Fuse’s death as the narrative shifts to her spiritual heirs, yet his actions remain the axis upon which the Satomi lineage turns, cursed and resurrected by his divided legacy.
