BanG Dream! Movie: Episode of Roselia - II: Song I Am.

Roselia has endured enough setbacks to know that reaching FUTURE WORLD FES will require more than technical skill. As autumn arrives, each member takes another step forward: Lisa grows through writing lyrics, Rinko begins composing, and Yukina and Sayo reflect on the promises they are making to their future selves.

With contests, performances, and their ultimate festival goal still ahead, Ako begins to fear what might happen once the dream they have chased for so long is finally within reach. The five must decide what Roselia means beyond a single stage and whether they can move toward the future without losing the bond that made them a band.
