Now here's a quarky vampire series to check out!
Basically it's about a cute vampire named Karin who is not your normal, everyday vampire. While her family are all blood-sucking ones due to lack of blood, she on the other hand
produces too much blood in her system. Because of that, she
transfuses blood into her victims. Karin practically lives a normal life like going to school as a schoolgirl until the day a guy name Kenta entered her life.
Alright, here are a few character profiles (well, only 2 for now, and they're not really profiles

):
Karin Maaka, the blood-giving vampire who occasionally gets nosebleeds. She's pretty cute, and quite sexy.
Kenta Usui. And yes, he seriously resembles to Ichigo from Bleach and Seiji from Midori no Hibi. Overall, he's the hard-working type since he and his mom are pretty much struggling through life (he doesn't really eat much though).
And finally, don't let the OP sequence fool you; J.C. Staff thought it'll be more quarky if they made it ridiculiously ecchi (not that I'm complaining

).
