TRIGGER goes missing when they're scheduled to perform at the Tokyo International Music Art Festival, so IDOLiSH7 and Re:vale work together to look for them. Ryunosuke is rescued sooner than the others thanks to Nagi's quick wits and rushes to Zero Arena, but...
At least, not until I've 
taught you the true hell
على الأقلّ، ليس قبل أن أعلّمك
كيف أنّ عالم البشر
Zumindest, bis ich dir die menschengemachte
Hölle auf Erden gezeigt habe.
Te enseñaré lo infernal que puede ser
este mundo de humanos.
Enfin, pas avant de t’avoir fait goûter
à l’enfer sur terre !
Almeno, non finché non ti avrò insegnato 
quanto sia spaventoso
Pelo menos, não até que eu
mostre o verdadeiro inferno
По крайней мере, пока не покажу
тебе истинный ад мира людей.
