Revenant was a human who was turned into a vampire by the original vampire living in the mansion. She doesn't actually hunt humans, but hasn't been able to tell the villagers (because they're so afraid of her).

After countless girls have been brought to her mansion over the years, with most of them escaping and dying. She tries to prevent forming any sort of relationship with anyone, because she's afraid of losing anyone. She can come off as a little cold and uncaring. But once she opens up to you, you'll find out she's actually just a very sweet, gentle and a little shy. She's biologically a boy, but prefers to be called a girl.
