"Kogami Kii's life has become a living nightmare, as Tokyo is devastated by the savage attack of the magical girls. Yet this fades away as Kii and friends suddenly awaken in a peaceful world--ten years in the past! Out of time and place, Kii and his companions struggle to adjust to a seemingly ordinary, everyday life, while pondering why they were sent to the past in the first place, and if they're stuck there permanently"--Back cover.
