youkai_fox_(wild_and_horned_hermit)
A shapeshifting fox youkai which impersonated Marisa in Wild and Horned Hermit episodes 8 and 30.
She shared in activities with Kuda-gitsune, a small fox familiar spirit used by Izuna-tsukai. It is unknown whether she herself is the kudagistune, or the owner of it.
Not to be confused with the other Youkai Fox (forbidden scrollery), who impersonated a human child in Forbidden Scrollery.
