OVA
Description
Nakoruru, an Ainu miko born October 11, 1771, hails from Kamui Kotan village in Ezochi (Hokkaido). Her priestess role forbids marriage, creating central conflict. Severely wounded in battle, she collapses near her village and is rescued by childhood friends Yantamu and another unnamed companion. Yantamu's protectiveness signals deeper feelings, forming a love triangle complicated by Nakoruru's vows and her friend's affection for Yantamu. Recurring nightmares of her near-fatal battle disturb her peace.

Descended from a lineage of Ainu maidens, she possesses strong spiritual powers. Her family includes younger sister Rimururu, grandfather Sanouku, and grandmother Monashiri. Following her father's death, she inherited guardianship of Kamui Kotan, symbolized by receiving his ceremonial makiri dagger, Chichi-ushi (Father Bull). Her deep bond with nature allows her to hear its voice and sense spiritual disturbances.

She fights alongside animal companions: the mountain hawk-eagle Mamahaha and the wolf Shikuru. Mamahaha creates combat tornadoes with its wings and carries her short distances, while Shikuru offers ground support. Nakoruru's abilities include healing wounds using natural energy, reflecting projectiles with her cloak, infusing her blade with ki for energy slashes, and dimensional travel. This power lets her spirit cross spacetime without physical toll, enabling appearances in other timelines to prevent disasters.

Her story involves significant sacrifice. After defeating Mizuki Rashojin, she restores nature's balance by merging her soul with Gaia, becoming a "holy spirit who wanders through time" in a form resembling a koro-pok-guru (dwarf). Later, she awakens from dormancy to fight threats like Yuga the Destroyer, returning to hibernation for Kamui Kotan's healing. During the Warriors Rage incident, she transcends further as a Maiden of Light but is weakened by Jigen Taishi's magic, requiring her sister's aid to defeat Oboro.

She grapples with her identity through the alter-ego Rera, a bloodthirsty counterpart embodying repressed desires. Rera constantly warns of approaching evil, causing Nakoruru to distance herself, even from her protégée Mikato. When Mikato discovers this truth, Nakoruru loses her powers due to perceived selfishness but redeems herself defending Kamui Kotan from demons. She also pursues Rimururu when her sister flees after sensing the Holy Spirit's silence, fearing for her safety amidst looming calamity.

Nakoruru exhibits a calm, gentle, and maternal demeanor, especially toward Rimururu, though others sometimes perceive her as doll-like—a description she dislikes. She prioritizes non-violent solutions and protects the vulnerable, yet harbors personal desires conflicting with her duties, a duality unsettling characters like Krohnen. Her combat style employs the Dancing Sword Arts of Shikanna-Kamui, emphasizing speed and precision with the short-ranged Chichi-ushi dagger. She utilizes Ainu-language-named moves and animal-assisted attacks, with her offensive strength balanced to be intentionally weaker than other fighters.

Her disposition evolved: stoic in her 1993 debut, later portrayals depicted her as cheerful, but the 2019 series reverted to her initial solemnity, noting she rarely smiles. She serves as a cultural tribute to the Ainu, reflected in her design, stages, and reverence for nature. Beyond fighting, she participates in environmental campaigns and children's social programs, often alongside Terry Bogard.
