Tayura Minamoto, the adopted younger brother of Chizuru Minamoto, shares her identity as a fox spirit despite their lack of blood ties. A classmate of Kouta Oyamada, he initially nurtures a simmering jealousy over Chizuru’s romantic attachment to Kouta—a tension she attributes to a sister complex. Over time, this rivalry evolves into protectiveness, as he intervenes to shield Kouta from Chizuru’s eccentric culinary experiments and other perceived risks.

His demeanor blends composed restraint with playful mischief, frequently needling Chizuru about her age or dubbing her bond with Kouta as "love birds"—a habit that invites comedic physical retribution from his adoptive sister. Yet beneath the teasing lies unwavering loyalty, exemplified when he challenges Saku, a wolf spirit, to ensure Chizuru’s safety.

Romantic intrigue emerges through his tentative pursuit of Akane Asahina, the class representative with a stern exterior. Though met with initial rejection, their rapport softens into a gradual, mutual understanding. Tayura embraces Akane’s reserved nature, their banter occasionally tinged with his understated masochistic flair.

Adopted into the Minamoto family and chronologically younger than Chizuru, Tayura’s early history remains undefined. Across manga and anime adaptations, he navigates both comedic clashes and supernatural confrontations, aiding Chizuru in disputes against other entities. While his fox-spirit abilities lack explicit elaboration, his combat interventions and protective instincts suggest powers consistent with his heritage.
