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 a new order instructing the girls to perform at ITF (Idol Tokyo Festival), known as a stepping-stone to success for idols. This is the first festival appearance for 22/7, but after seeing other idol groups they realize that they lack cohesiveness.

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.
