Plot
A popular social game known as the Magical Girl Raising Project has the ability to grant players a 1 in 10,000 chance to become a real life magical girl. Each of the magical girls possess unique abilities and earn Magical Candies by protecting people and performing good deeds. However, at some point, the administration has decided that sixteen magical girls in a certain city is too many, announcing they will cut down the number in half by having the magical girl with the fewest Magical Candies each week lose their powers. However, the girls soon discover whoever loses their powers will die, and as the rules of the game become more twisted, the girls find themselves dragged into a life or death battle of survival against each other.
