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'm so sorry!
!أنا آسف جدّاً
Tut mir echt leid!
¡Le pido mil perdones!
Toutes mes excuses !
Sono spiacente!
Eu sinto muito!
Простите, пожалуйста!
