The Chosen Children have been reunited with their Digimon partners, who no longer remember them due to the effects of a digital reset. While everyone tries to reconnect with their digital monsters, Sora Takenouchi encounters resistance from Piyomon, who stubbornly refuses to speak to her. Suddenly, an attack by a hostile Digimon separates the group, scattering them and their Digimon across the Digital World.

Back in the human world, Daigo Nishijima of the Incorporated Administrative Agency receives a warning that a new entity is in pursuit of "Libra," which he believes to be an alias for Meicoomon. For some reason, Meicoomon retains all of her memories and therefore still recalls her partner Meiko Mochizuki, who has come alone to the Digital World to find her. If they hope to identify what other forces have been driving the incidents thus far, the Chosen Children must survive the obstacles of the recreated Digital World and make their way back home.

IDOLiSH7 is more successful than ever, but no one is smiling because a new threat has taken the stage: the debuting idol group ŹOOĻ. Managed by the nefarious entertainment executive Ryou Tsukumo, they will stop at nothing to get their way, resorting to all kinds of underhanded tactics to bring down their rivals. TRIGGER's image has already been ruined by scandal, and IDOLiSH7 and Re:vale are headed for the same fate—or worse. Meanwhile, Zero, the legendary idol who disappeared 15 years ago, continues to haunt the present through those he left behind. His manager seems to be in contact with Tsukumo for his own schemes, and Zero's songwriter reveals himself in a letter after having been missing for years. IDOLiSH7 finds an ally in Re:vale to thwart ŹOOĻ's plans while trying to make sense of Zero's colleagues' actions, but it may be impossible for everyone to emerge unscathed.
