The system doesn't care which girl you love; it will kill her to balance a spreadsheet. Sixteen magical girls wake up one morning learning that only eight survive the week, and the show refuses the mercy of letting you predict who makes it out. What started as a power fantasy becomes a slow-motion disaster where friendship is a liability, and the real power, the one that matters, belongs to the algorithm deciding which dreams get to live.

In N-City, a popular social role-playing game called Magical Girl Raising Project secretly picks a rare few of its players to become real magical girls, with remarkable looks, physical strength and unique magic. Koyuki Himekawa is one of them, taking the form of her avatar, Snow White. Sixteen magical girls operate in her district, helping people in need and earning Magical Candies for their good deeds. Then the administrators announce that the number of magical girls must be cut in half because of a problem with magical energy. Each week, whoever holds the fewest candies loses her powers. When the first girl to drop out meets a real tragedy, the rest learn what losing actually costs. As new and more twisted rules appear, the contest turns into a deadly struggle for survival among the girls themselves. Horror and psychological thriller elements drive this dark take on the magical girl genre.
