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 told you, there isn't a language 
in this world I can't learn.
أخبرتُك، لا توجد لغة في هذا العالم
لا أستطيع تعلّمها
Du weißt doch: Es gibt keine Sprache,
die ich nicht lernen könnte.
Te dije que no hay idioma en este mundo
que no pueda dominar, ¿no?
Je t’avais bien dit
qu’il n’y a aucune langue
Te l'ho detto, non esiste lingua al mondo 
che non possa imparare alla perfezione.
Eu te disse, não há uma língua neste
mundo que eu não possa aprender.
Я говорил, что в мире не найдётся
языка, который мне не по зубам.
