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?
But we believed we
could be lasting and strong
waren wir davon überzeugt,
eines Tages wahre Stärke zu erlangen.
pero creíamos que duraríamos
y permaneceríamos fuertes.
pero creíamos que duraríamos
y permaneceríamos fuertes.
Mais nous étions sûres
de pouvoir devenir plus mûres
Ma ho sempre creduto
 che saremmo diventate più forti
Mas acreditávamos que
poderíamos ser duras e fortes
