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…

Two new plates have emerged from the Wall. The first is the name of Miu’s idol group, “22/7,” and the second instructs the staff to conduct a group evaluation. Amid the confusion, each member prepares for the assessment; however, Miu falls into despair as she is unable to imagine herself as an idol. With tensions running high, a panel of strict judges convenes to evaluate each girl. Nicole stands out above the rest with her excellent performance, but Miu is unable to even properly introduce herself…

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 22/7’s successful debut show, the Wall issues a new order: “Have a successful gravure photo shoot at the Hitome Senbonzakura cherry blossoms.” Gouda and the staff scramble to book a cover photo shoot with a magazine to fulfill the unreasonable request from the Wall; however, Sakura is overcome with emotion.

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.

The Wall suddenly issues an order stating that, “The leader of the group is Reika Sato.” Having a strong sense of responsibility, Reika worries about her newly appointed position. The Wall issues another order instructing 22/7 to fly to Okinawa to shoot images for a photo book.

Many members of the group have collapsed due to exhaustion. 22/7 has been inundated with bookings and their schedule is full again today. In this urgent situation, the only member that is fine is Jun.

22/7 has been booked for a huge headliner show and the group is in good spirits. While the girls are visibly excited about their upcoming show, Akane is calm and collected as usual, even almost robot-like. What inspired her to become an idol?

With the success of their headliner show, everything seems to be going well for 22/7 as they are approaching their fist anniversary. As a reward for their hard work, the Wall gives the members a two day trip to a hot spring.

The Wall suddenly issues an order for 22/7 to disband. Miu and the girls are frozen in disbelief and even Gouda can’t hide his confusion, but the orders from The Wall are absolute. The management is forced to close their office and 22/7 holds a press conference announcing their breakup.

22/7 has disbanded based on the orders from the Wall. The GIP office has shut down and all the members have gone their separate ways. Nicole had the strongest ambition to become an idol and is furious about this outcome.

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.
