 Merry Christmas @nezkovsou! I give you some Angel/demon AU! Originally I was gonna do a more traditional fantasy au, but I had some trouble figuring out how to compose it. I’ll be sure to send it to you if I ever do.
Still had a lot of fun with this tho, especially with Kei turning from an angel into a demon, all for his human charge
