Isai

Isai is Kourin's nyokai and serves as one of Kourin's shirei. She only appears in the anime. Isai's appearance is an anthropomorphic creature covered entirely in fur and possessing red-tipped feathery wings. Her hands and legs are like a leopard, and she has spots on her paws, legs, and tail. Her feet have talons like a bird, though they are also covered in fur. (Source: wikia)
