An Angel(?), An existence that was supposedly humans with wings, are at war with humans due to a stupid reasons that humans are foolish enough to accept, even though it isn't explained. Seriousness aside, the protagonist's name is Atleus, an Angel, a soldier, with a trustful Sword named Angel in their hands at the next moment, they would, and will, have fun?... Eh, I'm not paid to explain any further, so just don't read it. (Do note, it's a short story... Probably.)
