This is a world where the existence of magical girls is recognized. A game called "Magical Girl Cultivation Plan" can select one out of a million to create a real magical girl, and what awaits these lucky girls will be the admiration of thousands of people and a bright future. However, one day, the operator suddenly announced that the number of magical girls would be cut in half, and the method turned out to be a cruel competition among the existing magical girls. The innocent and kind girl Shirayuki (voiced by Nao Toyama), the cold-hearted ninja Ripple (voiced by Aimi Numakura), the holy girl with a giant sword (voiced by Ayane Sakura), the carefree Max Speed (voiced by Yumi Uchiyama) riding a broom, and the sharpshooter Disaster Mary (voiced by Kikuko Inoue), a war is about to begin between these magical girls selected by the mascot Fab (voiced by Kurumi Mamiya).
