Mayuko Inoue, a human girl with blonde hair and warm brown eyes, radiates a sweet, feminine charm. As a steadfast ally to best friends Ushio Aotsuki and Asako Nakamura, she aids their pursuits with unwavering loyalty. Her ancient lineage stems from the revered shaman Jie Mei, granting her the rare ability to craft psychic barriers powerful enough to subdue entities as fearsome as Hakumen no Mono. This heritage binds her to the Oyakume succession, a sacred role entwined with ancestral shamanic duties.

She persistently offers hamburgers to Tora as tokens of affection, her romantic overtures leaving him bemused. Though quietly nurturing feelings for Ushio, she selflessly champions his deepening connection with Asako. Later, she welcomes Kirio Inasa as her stepbrother, forging new familial bonds.

Gradually embracing her shamanic legacy, Mayuko harmonizes personal ties with her ordained responsibilities. Her latent barrier-weaving power emerges as a vital tool against supernatural dangers. Interactions with Tora blend fondness and complexity, as she affectionately dubs him “Tora-chan” while deftly navigating his mercurial temperament.
