In N-City, many girls escape reality by playing Magical Girl Raising Project, a popular social game where they embody their magical girl dreams. Koyuki Himekawa, known as Snow White in-game, receives an unexpected notification one night—she's been chosen to become a real magical girl. As Koyuki and other selected players start aiding the city's inhabitants, a grim announcement follows: the admins aim to decrease the magical girl count. Each week, the one with the fewest Magical Candies, earned through their heroics, will lose their powers. The stakes grow dire when the first dropout faces a tragic fate, revealing the harsh consequences of failure. With escalating eliminations and sinister regulations, the girls grasp the truth: their supposed competition is a brutal battle for survival.
