Race Vampire Occupation Aristocrat, Royal Guard Noé's childhood friend and the sister of Louis and Veronica. Her father is Count de Sade and her grandfather is Noé's teacher. She is a flirtatious, playful, energetic, and charming young lady. She strides with style and elegance, even using a machine to spray rose petals when she first appears. However, she isn't afraid to hurt anyone who she suspects of harming those close to her.

It is later revealed that Dominique and Louis are actually twins and because of that they were raised seperately since twins mean bad luck to vampires in their culture. Dominique blames herself for the death of Louis and at one point even cuts her hair to resemble him more because she thinks Noé would've preferred to have Louis live instead of her.
