In many stories I've read there's always an excuse, it might depends on probability, compatibility or the vampire's will to have a servant... Or maybe hunter chan is not a virgin?
There's all sorts of reasons other than those too. For example I recall one fairly established vampire trope being that a vampire drinking a human's blood doesn't make one a vampire but the human drinking the vampire's blood would.
Huh, that was simultaneously the single best episode of Comic Girls and the worst
gotta agree with you... There were some really good parts! but uh not very well balanced out
Though I'm kinda digging Moetas weird thing with being scolded by the teacher...
