Due to the creation of the virtual city of Oz, anyone can access the Internet at any time, for information, to pay bills or play games online. In his spare time Japanese high-school student Kenji works as a maintenance computer programmer for Oz. When Natsuki, the girl with whom he is secretly in love, invites him to go to Nagano for a few days for a family party, he promptly accepts. The night after the banquet, Kenji has gone to bed when he receives a strange email on his mobile phone that contains numbers and the following message: Decode me! Piqued by this challenge to his mathematical abilities, although still half-asleep, he tries to work out the puzzle and solves it. Next morning he learns that his avatar, the personification of an individual in the virtual world, is causing trouble in Oz and that he is wanted by the authorities.
