Original summary

22/7 make a comeback in front of their fans on 12/24, which is the anniversary of when they formed the group. The next day the eight members gather at the agency, where they discover that the Wall has been completely restored to its original state. As the mystery deepens, Sakura proposes a Christmas party to celebrate the reunion of the group and to clear out any bad vibes. Suddenly three strangers enter the room. They are wearing the same uniform as the eight members, and they introduce themselves as Mikami Kamiki, Yuki Tojo, and Tsubomi Hiiragi. They claim that they are new members gathered by the Wall.

What happens in the episode

This episode advances the idol-project mystery by putting the group under another demand from the agency-and-Wall system. In PopRot terms, the important movement is not only the task itself, but how the girls process being turned into performers before they feel emotionally ready. 22/7 make a comeback in front of their fans on 12/24, which is the anniversary of when they formed the group.

The key viewing angle is the gap between public idol polish and private discomfort. The show keeps asking whether a group created by orders can become a real unit once the members start seeing one another’s fears, histories, and strengths.

Watch or skip?

Watch. 22/7 is character-forward, so even setup-heavy episodes matter for understanding later group tension. Completionists should also watch the extra episode because it closes the anime experience as bonus material.
