The Diabolik Vampire Hunter

Hajime Hime is new to vampire hunting and her first job was to assassinate one vampire. The people who assigned it to her gave her only one thing about this vampire. That he had red hair and that was it.

Hime soon arrives at the Sakamaki mansion. All is fine and she thinks she has found the vampire that she must assassinate when another one appears. They keep on appearing until there are six vampires.

They soon figure out that Hime is a vampire Hunter and she is forced to stay there. They are now wondering why she was assigned to kill one of them.
