Takeoff
While the rest of the Suppression Army takes care of the Bio-Zoid guards, Ruuji, Kotona and Ra Kan make their way into Ironrock's forbidden valley. Kotona is reunited with Rina, who leads them to the Makiri's sacred grounds, where the Gildragon is buried. Rina and Kotona speak the keywords and the ground splits open, releasing the Zoid. However, Kotona is unable to pilot it. Sensing this, Souta rushes to her aid while the rest of the group battles Zairin. With Souta's help, Gildragon is activated, and the others jump on board as it takes off.
