After overcoming numerous tribulations, the members of Roselia promised to appear on FUTURE WORLD FES.
It is now Autumn...

Through writing the lyrics of "Promise," Lisa has matured.

Watching the change of color in the autumn leaves, Yukina and Sayo expressed their resolve in a picture letter to their future selves.

Driven by the wish to do something for Roselia, Rinko has started to compose a new song. 

"The remaining quests are the contest, the tournament, and FUTURE WORLD FES..."
Reflecting on their goals, Ako starts to feel anxious.

What view will the five of them see beyond FUTURE WORLD FES?
On that note, Ako, has that
countdown already hit zero?
Ach ja, Ako. Hat der Countdown
eigentlich bereits die Null erreicht?
Por cierto, Ako,
¿ya terminó la cuenta regresiva?
Por cierto, Ako,
¿ya ha terminado la cuenta atrás?
Au fait, Ako, ton compte à rebours,
il a atteint zéro ?
Ora che ci penso, Ako,
 quel countdown ormai segna zero, no?
Por acaso, Ako, aquela contagem
regressiva já chegou a zero?
