Amano Akari was looking for the western style mansion in the woods becase people say that there is a doll-like young girl there whose appearance has not changed in a long time. Once in the woods however, Akari gets lost. She's saved by a young girl, Sophie, who claims that she's a vampire. However, Sophie doesn't ever attack humans, instead she lives a modern and down to earth life.
