Levi is one of the first Vampire Tamers, usually people called on the Vampire hunters to take care of their "issues" but Levi had bigger goals. He wanted to tame these "wild creatures" and he's been quite successful. (Though nobody is really sure of his method's) Regardless, whenever people want a safe and non deadly alternative, he's who they call

It's late on a Tuesday night, around midnight when he get's a call from the police station. Apparently they had found a vampire and hopes he'll come in and take you.
