In recent years, beings called Kaii have repeatedly assaulted urban centers, causing widespread havoc. Eliminating these creatures quickly turned into a sought‑after and respected vocation, performed by magical girls. Over five hundred firms—ranging from modest outfits to major enterprises—provide their services and countless volunteers for those in need.
Kana Sakuragi, a diligent university graduate, struggles to secure employment despite numerous interviews. During her latest interview in the city, a Kaii erupts, and Kana finds herself aiding the magical girl who confronts the threat. Though inexperienced in combat, Kana uses her remarkable memory and knowledge to help subdue the monster.
Hitomi Koshigaya, the determined magical girl who tackled the Kaii, sees Kana's potential and invites her to join Magilumiere Magical Girls Inc., the startup where Hitomi is employed. Eager to make a difference for the greater good, Kana accepts and becomes a magical girl herself. While she may not fit the corporate mold, it quickly becomes evident that her true destiny is to emerge as one of the most exceptional magical girls ever.
