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...
I won't leave behind the men 
who have fought alongside me.
لن أترك الرّجل الّذي كافحَ بجانبي
Ich werde meine Mitstreiter
nicht zurücklassen.
No abandonaré
a mis compañeros de batalla.
Je n’abandonnerai pas
mes camarades de lutte.
Non abbandonerò mai le due persone 
che hanno sempre combattuto al mio fianco.
Não vou deixar para trás os
homens que lutaram ao meu lado.
Я не оставлю тех, кто сражался
бок о бок со мной.
