IDOLiSH7 is invited to perform on Sound Ship along with various other artists, including TRIGGER. Given TRIGGER's popularity, it's no surprise that most of the fans in the audience are here to see them. IDOLiSH7 puts on a great performance regardless, but Riku notices that TRIGGER still hasn't come to the stage...
I'm saying if it's a "grown-up thing,"

Tout ce que je dis,
Se si tratta di "cose da adulti",
Só estou dizendo que se isso é "algo entre
adultos", que resolvam isso como adultos.
Раз это «взрослые дела», то и вести они 
должны себя по-взрослому.
