Although IDOLiSH7 is currently enjoying success, the idol industry has been cast beneath a shroud of darkness by the appearance of ŹOOĻ, a new group managed by the unscrupulous Ryou Tsukumo. ŹOOĻ is determined to topple their rivals through dishonest schemes, even stooping as low as spreading scandalous rumors to tarnish TRIGGER's reputation. Now, IDOLiSH7 and Re:vale find themselves embroiled in the same dangerous situation, with the added complication of the disappearance of the legendary idol, Zero. With Zero's former manager working alongside Tsukumo and Zero's songwriter making a mysterious reappearance, the future of their careers is uncertain. Preventing ŹOOĻ from seizing the throne and safeguarding their own livelihoods is now shrouded in ambiguity.
