Orochi-Onna, forged from a shattered fang of the serpent deity Yato-no-Kami following Enma-Daiō’s ancient victory, manifests as an anthropomorphic serpent. Her scaled form blends pale green and dark grey underbelly, crowned by a horned forehead, piercing yellow slit-pupiled eyes, and cascading red hair. A rattle-tipped tail sways behind her humanoid torso, her figure accentuated by a midsection slit mimicking legs. Concealing her nature, she inhabits the human world as Maya Hibino—a schoolteacher entwined in Nezumi-Otoko’s unrequited affections.

Torn between purpose and solitude, Orochi-Onna initially enacts Yato-no-Kami’s vengeance but finds kinship in Nezumi-Otoko’s marginalization. Their bond fractures her allegiance, spiraling into despair when she chooses self-sacrifice, haunted by both duty and the erosion of their fragile connection.

Her serpentine gifts grant lethal agility, corrosive acid secretions, razor claws, and crushing constriction. She sheds her skin effortlessly, while her Maya guise infiltrates society to destabilize Enma-Daiō’s seal by exploiting human discord. Mirroring Tsukinowa of *Orochi, the Eight-Headed Dragon*—another deity-born entity tasked with resurrecting a fallen master—her origins spark debate, cited as emerging from either a fang or a discarded scale. Yet her path inexorably converges on tragedy: a sacrificial end, her master’s revival unfulfilled, and her yearning for belonging left adrift in the wake of severed bonds.
