Im looking for a manga i started reading a little over a year or so ago. The art is super good and it's definitely newer. It's about a guy who dies but survives by becoming a vampire girl's familiar. He has to fight other vampire's familiars to protect his gf from dying because i think his vamp/mistress saved her. But in order to save her he needs to keep killing and he can't get used to it.
