Simple Idea?

[Temptress_Akumu]

Name: Lilly
Age: Looks 21
History:
Lilly was once human, long, long ago. She was killed along with her family, the details of her past are blurry however she knows it was bloody and the figure of the killer is unclear, it's just a large shadow of a figure. Now her job it to protect a select few people who are meant to do great things.

Plot:
Lilly is watching over a young man who is bound for great things; however she is not the only one who is watching him. There is a demon that is out to destroy the young man. But when he sees Lilly, there is a spark for it was him who killed her and her family that long while ago. He destroyed her for she would not give into him and now he has another chance to have her.

Now I know this is not the best idea, but I really want to do a Demon/Angle rp and this is the best idea I came up with. So if you are interested and have a better idea or want to tweak this idea or just want to jump into it, message me!
