Chibi Vampire, Volume 2 (Chibi Vampire #6-10)

Kenta sees Karin at work and school, each day serving as a reminder that something about the girl with the oft-bloody nose just isn't right! He's suspicious... and he's not exactly subtle about it. Fearing that he might discover her secret, Karin decides to kill this potential problem - with kindness! She goes out of her way to do all kinds of nice things for him. But when Kenta catches her "feeding" yet again, the gig may be up. So what's a vampire girl to do? Why, take the boy home to meet her parents, of course!
