A mysterious being that serves as Adele's sole means of communication with the nanomachine network. Nano watches over the microscopic machines responsible for magic in the other world—essentially the backbone of how that whole system works. The character design shifts between media: in the manga, Nano appears as a small, sphere-shaped robot, but the anime redesigned it as a young cat instead. Fans often note that Nano represents a more personified take on the nanomachines compared to the novel series, where they function as a completely impersonal force.
