Ukemochi

Ukemochi is a Byakko spirit and, alongside his brother Miketsu, the familiar of Izumo Kamiki, having previously served her mother, Tamamo Kamiki, taking human form to help with household duties.

When Tamamo was possessed by the Nine-Tailed Fox Spirit, Ukemochi rushed to protect Izumo's younger sister, pulling her out of harm's way, though what became of him in the aftermath remained unclear until he resurfaced at Izumo's side at the start of the series.

More relaxed and playful than his brother, Ukemochi takes his role as Izumo's familiar seriously without Miketsu's characteristic pride or aggression, appearing as a white fox marked with a blue stripe and small tomoe-shaped markings, dressed in a red apron bearing his name.
