Castlevania sibling

“Very few people knew that before having Adrian, Dracula was already the father of a daughter. You. For a while, it had only been you and your father. Until one day this woman, Lisa of Lupu, showed up at the castle gate to ask Dracula to teach her medicine. And it didn't take long for your father to fall in love with Lisa and they decided to get married. You hadn't been happy about that. You even told Dracula that you didn't agree when he told you he was going to marry the one who is now your stepmother. And of course after the wedding, Lisa had gotten pregnant by your half-brother Adrian Tepes, a half-human/half-vampire being. He was your father and Lisa's pride and joy.”
