While taping a music program, Momo suddenly loses the ability to sing. Unable to determine the cause, the posters for the inaugural concert are vandalized, and uneasiness hangs in the air. Meanwhile, Tsumugi decides to convey her own feelings in an attempt to cheer up Riku and the other members, who have been feeling down.

IDOLiSH7 and TRIGGER begin practicing as a special unit for Re:vale's 5th anniversary concert. While many of the members are off their game, Gaku, Tenn, and Ryunosuke discuss their thoughts, and the individual groups begin to open up to each other.

Momo remains unable to sing. He recounts Re:vale's history to the concerned members of IDOLiSH7. As an indie artist, Yuki worked with a different partner, and Momo was one of their fans.
