When Roselia was introduced, they already had that completed aura to begin with. 

I was genuinely surprised and moved to watch their struggles and tribulations before that. 

I hope everyone will enjoy the living, breathing Roselia in the movie. 


SANJIGEN CEO, Hiroaki Matsuura

To deliver this Episode of Roselia movie animation to everyone, we were determined to work on this project as SANJIGEN. 

Above anything else, the story of Roselia progresses with the charm and personality of each character. 

Everyone’s passionate cheers grow BanG Dream!, so please watch the movie!

Once you are into the plot, you will start crying so be careful!


General Director, Kohdai Kakimoto

This was a movie by Roselia, with Roselia, for Roselia, as well as everyone who is a BanG Dreamer.

The five members, Director Mimura, and every staff member created this chronicle of Roselia.

Please watch this movie. 


Director, Atsushi Mimura

It has been a while since we announced the production of this movie. I’m really happy to deliver this to everyone!

This movie is enormously important to BanG Dream! and Roselia, so I’m very nervous.

The Roselia members put a lot of their passion into this. Please check this movie out!!


 Executive Story Writer, Yuniko Ayana

In the Anime “BanG Dream! 2nd Season” and “3rd Season”, I portrayed Roselia as upperclassmen figures to Kasumi and friends, but you can see Roselia just as they are in this chapter. 

I once again felt Roselia is wonderful after watching their relationship develop through their struggles and conflicts. 

Please look forward to not only the new song, but also the details we were able to put into this movie!


 Music Producer, Noriyasu Agematsu (Elements Garden) 

Warmest congratulations on the release of “BanG Dream! Episode of Roselia I : Promise!”

Why is Roselia, Roselia?

I was able to make sense of this question after watching this piece. 

I am going to put myself in this feeling for the upcoming music production!

BanG Dreamers, please look forward to it!


Music Producer, Junpei Fujita (Elements Garden)

Congratulations on the release!

I reconfirmed the bonds between the five of them and each of their passions to their music, through the detailed portraits of encounter and growth of the band. 

I listened to the feelings of each member closely to compose the music in this movie. 

The story will make you genuinely want to cheer for Roselia.

Don’t miss out on the concert scene as well!


Craft Egg CEO, Shuichi Morikawa

Congratulations on the release of “BanG Dream! Episode of Roselia I : Promise!”

I’m glad to be able to release the familiar story of Roselia from BanG Dream! Girls Band Party! and being able to enjoy it as a movie!

I really appreciate everyone who was involved for making this project possible. 

The movie became rather voluminous since it includes both the Band Stories and Event Story, but you will find something new every time you watch, so please watch it more than once!


BanG Dream! Girls Band Party! Contents Producer, Eisuke Sawamura

Congratulations on the release of “BanG Dream! Episode of Roselia I : Promise!”

It has been about a year and half since we started this project, and I’m very excited to be able to finally show this to everyone. 

We had loads of careful discussions with the production team to create a movie that everyone can enjoy regardless if they know BanG Dream! already, or if they are a first timer. 

To begin with, I would be happy to see if you enjoy this first part.
