Nuinokata, born Oku, was the wife of feudal lord Daigo Kagemitsu and mother to Hyakkimaru and Tahomaru. A tall woman with long black hair, brown eyes, and slender eyebrows, her features mirrored those of her eldest son, Hyakkimaru. She dressed in a pink kimono secured by a yellow sash and a green floral-patterned robe, later exchanging these for a plain white robe and ribbon upon renouncing her noble status. Known for her gentle nature, Nuinokata revered the goddess of mercy, championing empathy and peace above conflict. Her life shifted irrevocably when Kagemitsu discarded Hyakkimaru as an infant—an act she resisted but failed to stop. For sixteen years, she knelt daily before a headless Buddha, her prayers mingling guilt with desperate hope for her lost son’s survival. This fixation left Tahomaru, her second son, feeling emotionally abandoned, his perception of her care fractured by silence. Kagemitsu tormented Nuinokata psychologically for clinging to Hyakkimaru’s memory. Discovering Hyakkimaru had survived, she defied her husband, fleeing the castle with Dororo, Hyakkimaru’s young companion. The escape dissolved her marriage and branded her a traitor to the Daigo clan. When Hyakkimaru and Tahomaru clashed in battle, Nuinokata exposed Kagemitsu’s demonic pact to Hyakkimaru and stabbed herself, seeking redemption and freedom for her son from the demons’ curse. Surviving the wound, her actions nonetheless shattered the domain’s supernatural defenses. As flames consumed the castle, she held Tahomaru in their final moments, apologizing for his solitude before perishing. Adaptations varied her journey. The 1969 narrative concluded with her shielding Hyakkimaru from Kagemitsu, pleading for him to acknowledge her as his mother. The 2019 version extended her life, showing her assisting villagers and mending bonds with Hyakkimaru via Dororo’s influence. Both iterations underscored her relentless love for Hyakkimaru, defiance of Kagemitsu’s brutality, and tragic duality as a mother torn between duty and devotion.
