She is the little sister to Richter's fiancée Annette Renard. She is a distant blood relative of the Belmont clan (no mention of that connection is to be found in Castlevania: The Dracula X Chronicles, where she is instead said to be the daughter of a local lord). In Castlevania: Dracula X, she's also said to be the sister of Richter's beloved Annette, a detail that's not alluded to in the other games. She was later adopted by the Belmont family in Castlevania Judgment.
