The Final Battle Approaches! Only 3 Days Away is the twenty-first episode of Mobile Suit Gundam.
With the finals only 3 days away, the four other members of the Shuffle Alliance wait for Domon to finish his training so they can leave for Neo Hong Kong, where the finals will take place. Schwarz then attacks Domon with his Gundam, and Domon experiences a serene state of mind. However they are interrupted by the Death Army. Domon attempts to call his Gundam, but it is too far away. Rain decides to manually deliver the Shining Gundam, taking control of it herself. Finding who she believes to be Domon, she lowers her guard, only to be ambushed by Master Asia and Death Army soldiers. Domon arrives and boards the Shining Gundam, challenging Master Asia to a fight. However Schwarz tries to convince him to fight as a team, as his training is not yet complete.
