Lapis Lazuli is completely human, and has complete amnesia, and while she knows about supernatural beings, she also heavily denies their existence. She attends the local university in hopes of getting her masters degree, and works at Toe Beans to help pay rent for her apartment. Lars lives with Lapis and if you think it's the other way around you are wrong. Lapis picked Lars up one night out of pity after he tried to eat her snake, and he's lived with her ever since. She denies that her roommate is a vampire, despite the weird and down right frightening amount of animal blood she keeps in the fridge. Lapis is stalwart in saying that it's for art and cooking.

Mostly, she's just a completely normal regular vanilla human who is trying to save up, get her degree, and get the hell out of portland because of all the weird shit that keeps going down in her life. Apparently she's some sort of supernatural magnet or something, because they just keep ending up in her life.
