Plot
One day, Miu Takigawa suddenly receives a letter notifying her that she has been chosen as a member of a brand-new project. Half in disbelief, she heads over to the location stated in the letter and finds seven other girls summoned there in the same fashion. The girls behold a giant, top-secret facility and stand in bewilderment as they are told they are going to debut for a major record label as an idol group. A new kind of idol, never-before-seen, is about to be born here.
