IDOLiSH7 wins the JIMA New Artist award, which means they'll compete against TRIGGER at Black or White! Their work has earned them the attention of Douglas Rootbank, a famous American pop-rock artist. While Iori and Tamaki wait for the others to show up for their group meeting, a strange looking maintenance employee shows up...

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.

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.

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.
