Rosalina Hauntley is a teenage vampire-hunting princess who lives with her parents and two siblings in Transylvania, a place inhabited by vampires. She wants to live in a human town, but her overprotective father forbids it, as humans and vampires are enemies. However, she doesn't care and befriends two human teenagers, Danica Wenham and Nami Muller, who take her under their wing. Meanwhile, the local bully, Harry, and the snobby cheerleader, Angela, have no idea she is a vampire disguised as a human, so Rosalina and her friends must keep her true nature a secret. Yet, Rosalina stands up to her enemies.
