The Diva flies at low altitude to avoid enemy detection while passing through a desert, when it is ambushed by the "Phantom 3", a Vagan special unit whose desert-oriented gear gives them the upper hand. Kio and the others struggle to keep the enemy at bay long enough for the Age Builder to complete their newest weapon, the G-Hopper, and dispatch it to assemble the Gundam AGE-3 Fortress.
