Hey Zyx,
Hello! I'm sure you know the drill well enough, I just have a few things that need clarification, is she bisexual or asexual? This needs to be put into the history. What age is she? I know you say old enough, but how old is old?
You say that her occupation is complicated, yet not specify it in the history, in which you give us a "It will be told through roleplay." It doesn't give us a complete sense of her character, where she comes from, why is her family unknown, why her personality is the way it is...why doesn't she like humans?
These are some of the questions that should be considered.
Once you have made these changes, lemme know and I'll take another look.
