Miu Takigawa receives a suspicious letter from talent agency, G.I.P. Eight young girls including Miu are brought together by the hands of fate. The letter says, “You will be joining an idol group and debuting on a major label.” A man named Aida takes them to a top-secret underground facility with a mysterious “wall.” Miu and the girls experience a whirlwind of light and darkness as they make their way to the stage…

The Wall issues an order announcing that 22/7’s debut show will be on February 27th. Miu and the girls engage in grueling rehearsals every day to prepare for the show. Even though Miu was chosen as the center, she lags behind and slows down the progress of the group. What can Miu do as the center of 22/7? The day of the show arrives. What Miu sees from the stage is way beyond her expectations.

After the eight members of 22/7 gather and confirm their love for the group again, the Wall, which had been silent since the disbandment press conference, starts to speak again.
