A Japanese freelance photographer Kohei Morioka met a very cute girl named Hazuki at a haunted German castle he visited for his photographic job. It didn't take much time for him to realize that Hazuki is a vampire girl imprisoned in the castle by a magical barrier and is trying to make him her slave, yet to her surprise all her vampirish magics have no effect on him. With Kohei's help, Hazuki broke the magical barrier of the castle and escaped, but she managed to find her way to Japan and (with Kohei's reluctance) settled down at Morioka's grandfather's antique store.
