It was recently announced that Youjo Senki: Saga of Tanya the Evil would be getting an animated movie adaptation, and the news was celebrated with a beautiful visual. It features the main character, Tanya von Degurechaff, with her burning coat flying up behind her. It almost looks as though she has a pair of wings sprouting from her back. You can decide whether that is angelic or demonic.
Youjo Senki: Saga of Tanya the Evil is based on a series of light novels written by Carlo Zena and illustrated by Shinobu Shinotsuki. It tells the story of an elite yet stubborn Japanese salaryman who is reincarnated as a beautiful young girl in an alternate WWII. An anime adaptation aired during Winter 2017.
