Synopsis
Miu Takigawa lives a quiet and unassuming life, preferring solitude and avoiding notice from others. Her reserved personality makes workplace interactions challenging, yet she persists to support her mother and her beloved younger sister, Haru. This ordinary existence is disrupted when she receives a letter from the entertainment company GIP, informing her that she has been chosen for an upcoming project. Reluctantly, Miu heads to the designated meeting place, where she discovers others who have also received the same summons. Under a manager's guidance, the group is taken to an isolated, luxurious location, where they learn they must follow the orders of a mysterious entity called "The Wall." It is revealed that on December 24, 2016, Miu and the other selected girls will form the idol group 22/7 and make their debut performance, regardless of their preparedness.
