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...
On the sea, both blessings and 
misfortunes were up to the gods.
في البحر، كانت كلٌّ من المُبارَكات والبلاء بين يدي الآلهة
Auf dem Meer liegen alle Segen und
Katastrophen in den Händen der Götter.
En el mar, los milagros y las tragedias
dependen de los dioses.
La mer donne ou prend
selon la volonté des dieux.
La fortuna o la malasorte sono nelle mani degli dei,
No mar, tanto as bênçãos quanto
os infortúnios cabiam aos deuses.
На море и удача, и несчастья —
в руках богов.
