Chelsea Cassandra Hunter. She's from a family of monster hunters :0 (mostly demons and vampires) She's her parents 7th and final daughter (biiig family ._.;) Her mother got killed shortly after she was born by a demon. Her father cracked a bit after her mom died and blamed the death on her. So when she got fed up with his treatment of her and decided to move out when she was a teenager he had no problems with funding her (her family is kind of wealthy >.>)
Due to her family's nature as demon hunters she has been trained in combat since she was very small. The scar on her arm is part of the seal that keeps her from using magic and telling the future (yeah, she's named after THAT Cassandra) She's a powerful seer, but has a bad reaction to it. So, her girlfriend Autumn sealed her abilities for her own good.
One of her sisters likes dragging her to fancy parties. Cassandra is kind of -.- "Eh" about that. She also is inordinately fond of video games and is very good at them.
