Anri Chikura

He is a friend of Shou who continuously repeats words at least three times. though kind hearted he is not very bright and plays the flute to heal wounds and to rid monsters such as the werewolves in the second episode and heal Shou's wounds in the 1st episode. It is possible that Anri is a distant cousin of Shou, Kai and Kurisu because of his small white wings.
