In this future, a mobile phone like technology has people wear special visors to superimpose coordinated, instant virtual images over the top of their everyday real world. This cyberspace layer, space, interacts perfectly as you move about or touch things. It even allows children to have advanced Tamagotchi style cyberpets (very tidy!), or to make video calls using simple hand gestures alone. However, something is happening in Daikoku which the adults have not yet noticed. Cyberpets go missing, dangerous spherical robots patrol the skies and a mysterious gigantic character named Satchii seems connected to it all. When 6th grader Yasako moves to Daikoku to be with family, her beloved pet goes missing too, and she is drawn into the affairs of a Cyberpet Recovery Agency run by the local children.
