Magical Girl Apocalypse Vol 3

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