Kouhei meets a vampire girl named Hazuki at an old German castle, and she follows him home to Japan in order to look for her mother, but the two are constantly at battle over her unethical use of her vampire powers and embroiled in mysterious adventures.
In this volume we meet the Luna personality (i know I've called her Luna in all the reviews but I'm lazy about figuring out spelling today. I admit it.) Luna is sweeter then her normal personality and Kouhei is having a little trouble relating to her. It's interesting to watch everyone interact in this volume. I definitely enjoyed it more.
