IDOLiSH7 Second Beat!

IDOLiSH7 achieves their long-held dream of having their own namesake show, and the members feel like celebrating. President Takanashi explains that Mitsuki's talent for MCing that he's been displaying on variety programs was big for the group. Mitsuki cries tears of joy over the recognition he has received. The group begins planning more jobs to promote their show, and they are soon invited onto the show of top idols Re:vale. It will be their first real appearance with their seniors Re:vale. The members wait anxiously in their greenroom, but when Momo and Yuki arrive...?!

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!

Though the concert ended without incident, Riku was unable to perform in the encore due to an asthma attack. Fortunately, it doesn't affect the Zero Arena general manager's opinion of the concert, and IDOLiSH7 is officially offered an appearance at the inaugural concert. Mitsuki and Nagi are delighted, but there are reservations about whether or not the sickly Riku can continue acting as the center. Riku tries to act tough after his recovery, making Tsumugi wonder how to approach the situation. Meanwhile, she discusses a major decision with Iori.

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.

Tenn pays a sudden visit to the IDOLiSH7 dorms. Riku is simultaneously perplexed and delighted, but Tenn has harsh words for him. Later, Yuki, Momo, and Ryunosuke arrive. With members of IDOLiSH7, TRIGGER, and Re:vale at the dorms, the situation gets out of control...?!

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.

Mitsuki is traumatized when he happens to overhear some fans talking about him. Riku is criticized on social media by Iori's fans and begins behaving awkwardly towards him. Though Sougo is worried about the situation, he has his own concerns regarding Tamaki...

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.

Graffiti is written on posters for the inaugural concert. The rumor that the missing legendary idol Zero is responsible spreads. Meanwhile, IDOLiSH7 will release a new song with their second album, and Riku will return to the center position.

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.

Filming for the drama Tamaki and Sougo are co-starring in is going well. However, Sougo continues to worry about his encounter with Tamaki's younger sister, which he hasn't been able to tell anyone about. On the final day of the special unit's joint practice, Tamaki is shocked to discover that Sougo couldn't trust him enough to tell him about Aya.

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--

Re:vale prepare to close out the inaugural concert. The IDOLiSH7 and Trigger shuffle units perform the opening act. While watching their juniors perform, Momo and Yuki look back on the past five years they've walked together.
