Due to a deep trauma at school Sakurada Jun has refused to return. He spends his time in his room, surfing the web and ordering anything that takes his fancy, only to return the items just before payment is due. One day, he finds a web site that tells him to put his order in a drawer of his desk. He does so thinking it to be a joke, only to find that the letter disappears and a strange package arrives soon afterwards. It contains an exquisite doll, that, when wound, comes to life. She treats him as a servant of little worth, but over time helps him come to grips with his fears and in the life-or-death fights that soon follow her arrival.
