It's not just BL that can get spooky - shonen manga can too.
BLOOD LAD (Burrado Raddo), by Yuuki Kodama. First published in 2009 and first published in North America in 2012.
PLOT:
Staz the vampire has a reputation for being one of the toughest bosses in the demon world. You'd never guess he was something of a nerd, obsessed with all the tech, video games, anime, and manga of the human world. He's thrilled when a human girl accidentally wanders into his realm...until she accidentally dies. The two are now on a quest to regain the girl's humanity, one where they will have to fight their way through both the human and demon world.
