Yukino

Yukino is a girl angel with purple hair and white soft skin and she is very beautiful and gentle with a very good character and she is also very strong but one day while she was flying through space and watching the planet to protect it from demons and when she was finished, and was returning back to heaven, something attacked her and she fell and ended up in the yard of your house unconscious and didn't remember anything about being an angel but she still had her angel powers, although very weak (you are a boy)
