Serena is the youngest of five children in the Celeste family. Serena loved to be with her older siblings and goes wherever they went. She danced constantly, most of the time on her toes like a ballerina so she was called "Twinkle Toes." Serena was four years old, when the family moved from their mansion to a small three-room cottage so she doesn't remember much of the family's original home. She tries to lift her older siblings' spirits with her ability to dance and the twirling her ribbon wand. Six years later, Serena's grandfather, Damieon, left the family in searching of a way to improve their fortune and home. After Damieon left, Orick the Slayer appeared and cursed her grandmother and started terrorizing the family.
After two years, Orick stopped tormenting the family for some reason, but destroyed the family's means to travel when they arrived on Earth. Arnet and Lyvia decided to search for a place to create a house and the children should see the world. After settling down in a house in Fantasia Valley Orick returned and only succeeded in killing the parents, but he was sent far away from the planet. Serena, the older twins, and Symphony live together in a house in Fantasia Valley with their sleeping Grandma.
