Re-watching the fierce battle of the Gunpla Force Tournament, Riku once again yearns to be as strong as the champion. He and Yukio agree to try out the new weapons they've prepared, while Momoka, who has been inspired by them, finally decides to join GBN. The three of them dive into the Dimension, where a Diver who called himself Kyoya asks to accompany them in a Serial Battle mission.
The friend I was supposed to go with
can't come now.

معه لا يستطيع المجيء الآن
Mein Freund, mit dem ich verabredet war,
ist leider verhindert
El amigo con el que iba a entrar
no puede venir.

 non è potuto venire,
O amigo que ia me
acompanhar não pode vir.
Друг не смог пойти со мной,
