Yuki declares that he'll recommend IDOLiSH7 for the currently undecided performance slot at the Zero Arena inaugural concert. Zero Arena's general manager is scheduled to come to their next concert, so Tsumugi, who is in charge of the group's stage production, heads to Zero Arena to gather ideas. There she encounters a gentleman who claims to have worked in stage production in the past. Tsumugi's heart is moved by the way he describes his feelings towards idols standing onstage. His hints help her finish the set, and the concert begins!

Given Riku's unstable condition, Iori takes over as IDOLiSH7's center. The newly reborn IDOLiSH7 gets off to a solid start, both their first namesake show "Lovely Night With You!" and Mitsuki's MCing are well received, and the group's popularity grows.

Re:vale brings a new offer to the table: for IDOLiSH7 and TRIGGER to appear as surprise guests at Re:vale's fifth anniversary Zero Arena inaugural concert, and for the two groups to perform together as one special group.

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.

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.

IDOLiSH7 is accused of appropriating Zero's songs, so Takanashi Production holds a press conference. Nagi volunteers to face the press and explains that he was officially given the rights to the song by composer Haruki Sakura. However, a suspicious man dressed as Zero appears at the press conference, aggravating the scandal.

Tamaki and Aya are finally reunited. Tamaki wants the two of them to live together, but Aya informs him that she wants to remain with her new father who has been taking care of her. A surprising figure appears before the dumbfounded group. When they learn of his ambition, IDOLiSH7's feelings are united--
