Not sure if he is a vampire.
Cute story about Albert, a failed vampire, and the japanese embalmer he lives with. Albert was bitten by a vampire but his tranformatuon failed, leaving him as a bat during the day and a human during the night. He also does not have fangs so he cannot suck blood so he had to live off blood from bought raw meat. Albert was in America but ended up in japan when he was accidently frozen since he lived in a meat factory but ended up being packed and shipped with some beef
