Кохаку

Kohaku is a rather accident-prone angel who has come to Earth in search of their mentor, Hisui, but ends up trapped in a tree and attacked by a crow. They're rescued by Shuichirou, a young doctor so they feel indebted to grant him one wish even if the kind doctor is satisfied with all aspects of his life. Thus, Kohaku remains with Shuichirou in hopes of repaying him somehow (subsequently getting in other sticky situations as a result). Being an angel, Kohaku is neither male nor female. While often mistaken for a girl, many official translations of the manga use male pronouns. In the original, Japanese print of Wish, Kohaku is referred to using non gendered terms.

Wish spoilers After Shuichirou's sudden death, Kohaku is put into a hundred years sleep, so that Shuichiro will have been reincarnated by the time Kohaku awakens. One hundred years later, the reincarnation of Shuichiro, now 17, passes by his old house which awakens Kohaku. He has no memory of their past, so their relationship starts anew. Kobato spoilers Kohaku is an acquaintance of Genko and several of the inhabitants of the Spirit World, many who admire the angel's singing voice, and has commented on Kobato's progress and the consequences of Ioryogi's actions.

After meeting the angel, Ginsei begins visiting Kohaku on a regular basis, particularly as he begins to worry about Kobato and Ioryogi's fates if Kobato is unable to fulfill her wish. In the manga's epilogue, Kobato and Kohaku meets for the first time in Genko's shop and sing a song together in front of Ginsei. Kohaku's living with the current reincarnation of Shuichirou and tries to help him in every way possible. In the anime series, Kohaku is introduced early in the series and befriends Kobato. Because Ioryogi is aware of Kohaku's true nature, he constantly asks Kohaku if there's something they can do to change Kobato's wish, though Kohaku's response is always that there's nothing to do.
