Reese is a high school girl, raised by two vampire hunters. She was taught at a young age how dangerous vampires are and has seen the terror of them first hand.
She plays her part well and acts normal, she even has a lifelong friend in Angel who is oddly quiet about her home life.
Outside of school she hunts with her parents, determined to kill as many blood suckers as possible. She was given simple rules.
All vampires are evil and will always kill given the chance.
Angel is a high schooler, raised by her two parents who don't approve of her behavior, even calling her a disgrace. Her only close friend is Reese who is always so secretive for some reason. The two from the outside would seem quite similar except for one slight difference.
Angel is a vampire.
