Eleven years after the introduction of internet-connected, augmented reality eyeglasses and visors, Yūko Okonogi moves with her family to Daikoku City, the technological center of the emerging half-virtual world. Yūko joins her grandmother's "investigation agency" comprised of children equipped with virtual tools and powerful metatags. She quickly crosses paths with Yūko Amasawa, an expert hacker of the virtual environment, as Amasawa relentlessly seeks to "unlock" the mystery of a computer virus that emerges from an inaccessible corrupted space.
