Demoneslayer Stories

What am I? Who am I? A girl who is not human nor demon but an alien from a planet that's always that war, a warrior who has conquered many planets. After a failed mission she wakes up in a new planet, already mistreated, she assumes this planet is nothing more then a hostile place. As she explores she meets new people. Friends or foes? She must remember her past to know who she is, and needs to overcome what the first humans she met did, in order to truly live in this new and unfamiliar world. Can she co-exist with humans other then M!Y/n and F!Y/n? (MALE Y/N AND FEMALE Y/N ARE INCLUDED!!!!!)

A random concept my friend and I thought of.
