Kokkuri is an fox animal spirit of one of the folklore and was called by Kohina. When he first appeared, Kohina thought he was a cosplayer because of his ears and white hair. At first he had intended to merely haunt her, but soon he becomes worried about her terrible eating habit of cup ramen for every meal. He later decides to haunt her in order to protect her.
He can become a real fox. He is now a low-ranking ghost, but in the past he was a god of a shrine.
He doesn't get along well with Inugami.
