Yuuko Okonogi, newly arrived in the augmented-reality hub of Daikoku City, inherits a pair of old Dennou glasses and a virtual pet named Densuke from her late grandfather. Exploring the city's hidden Coil space, she crosses paths with a sharp-eyed hacker who happens to carry the same given name she does: Yuuko Amasawa, known as Isako. This short manga condenses the original TV anime's premise of two Yuukos navigating Daikoku's overlapping real and virtual layers.
