Well... she's a very, very old royal vampire, and the daughter of this world's version of Vlad Tepes/Dracula. Due to her nature, though, she's remained a child permanently. She's hired a truckload of maids to care for the castle and also instigated some reforms like shutting down the torture chamber her father ran and a variety of other things. She also imports a lot of stuff from other worlds, like her huge TV.
