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.
What if I don't regain the ability to sing?
ماذا لو لم أستعد القدرة على الغناء؟
Was, wenn sich das nicht wieder legt?
On fait quoi,
si je deviens incapable de chanter ?
Che faccio ora?
O que eu faço se continuar 
não conseguindo cantar?
А что, если я так и не смогу петь?
