Sekai will play Karies, the mysterious Muter King who appears before the main character, Kamen Rider Gavv/Shoma (Hidekazu Chinen). Sekai is known as a die-hard Kamen Rider fan, and in this film he transforms into Kamen Rider.
Sawamoto will play a mysterious young man. The relationship he will have with Shoma and the others in the film will be announced in the future. Kimura will play the Muter professor, Claap. Nakajima will play Taorin, a young man Shoma meets in the world he gets lost in.
Sekai commented, "I am truly honored to be in charge of the theme song once again. "Got Boost?" is a representative song for us and I feel like I grew up with Kamen Rider Gavv, and I think this new song will allow us to show a much different side of ourselves than we've had before. We created the choreography while imagining the world of this work, so I hope everyone will look forward to it! Personally, I love Kamen Rider as much as I love dancing, and I've grown up with it since I was a child, so I hope I can give back to Kamen Rider in some way through music."
