Тенко Ґьокуйо

Gyokuyou is a silver fox deity who is the half-brother/sister of Kūgen (it hasn't been clearly stated which, though female appears the most likely). Unlike Kūgen, Gyokuyou does not prefer to live with humans, largely due to the sealing of Kūgen. Gyokuyou was given the nickname "Tama" by Tōru when they first met. (Source: Wikipedia)
