While taping a music program, Momo suddenly loses the ability to sing. Unable to determine the cause, the posters for the inaugural concert are vandalized, and uneasiness hangs in the air. Meanwhile, Tsumugi decides to convey her own feelings in an attempt to cheer up Riku and the other members, who have been feeling down.
We're thinking of singing 
"Dis one." as our last song.
نفكّر بغناء "ديس ون" كأغنية أخيرة لنا
Wir hatten geplant, als Schlusslied
des Konzerts „DIS ONE“ zu singen.
La canción de cierre será "DIS ONE".
La canción de cierre será "DIS ONE".
On chantera Dis one
en fin de concert.
A dirla tutta, come ultima canzone 
vorremmo cantare "Dis one".
Pensamos em cantar a "DIS ONE"
como última música.
Подумываем последней
исполнить песню «DIS ONE».
