Being the sister of the human in the Star Sanses you have become a target. They try to protect you along with everyone else, but you still manage to get caught. You become a prisoner in Nightmares castle, but it isn't as bad as you thought it would be, considering you once had to deal with abusive parents and all. It isn't way to bad, and you feel more apart of them then you have with the others. Maybe you could help them out?

(Y/N) (L/N) was always one to take up a challenge. Her confidence and friendly demeanor landed her in the popular side. Not to mention she hangs with jocks and nerds. Anyone who wanted to be her friend, would become one. Her dad was a great athlete and her mother was a police officer. Although both are dead, they taught her self defense, all sports, and much more. She moves in with her brother who is one year older. When she joins Underhigh's basketball team, a certain skeleton wanted to know her more than a friends . . . . And he might not be the only one.
