Anon, Rāna, Soyo, and Taki were all deeply moved by Tomori's song. The matter is settled. Or at least, that's what they think. Then, they find out that they're scheduled to perform again. What will they do with only one song, no name, and no costumes?
I now know why our costumes 
haven't been decided yet.
عرفت الآن لمَ لم تحدّد أزياؤنا بعد
Ich weiß jetzt, warum wir
auf keinen Nenner kommen.
Je comprends pourquoi
t’avances pas.
Ora capisco perché 
non abbiamo ancora i vestiti.
То-то мы до сих пор без костюмов…
