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...?!

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.

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...?!

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.

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.

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.
