Kuniko announces the beginning of Metal Age's fight for survival against Atlas government, for the sake of everyone. Talsian makes his first appearance as chairman of Atlas. Kuniko, Takehiko and Momoko go to what remains of Yokota Air Base to meet K.D., who will be providing Metal Age with a gigantic stealth bomber. Meanwhile, construction workers involved in the building of Atlas strongly oppose the inhumane treatment the people outside Atlas receive. The protest turns into a widespread riot against Atlas security. Under Kuniko's command, the stealth bomber carrying Metal Age forces approach Atlas, but are soon attacked by Atlas air force. Karin takes this chance to make money from the war. The air force fires missiles at the bomber but end up hitting Atlas' supports instead. Kuniko goes outside the plane to destroy the remaining missiles with her boomerang. Miiko teaches Mikuni a lesson in fighting for a cause. Under control of Zeus, Atlas sends multiple defense drones that attack both the air force and the bomber. As Kuniko and Momoko try to destroy the drones, the drones are in turn destroyed by the strange artillery strike that hit Duomo earlier. K.D. makes a suicidal attack on a drone after deploying Metal Age forces, who fly off in jet packs. Kuniko destroys the last drone and is rescued by Momoko. As Kuniko watches K.D. parachute himself to safety, she notices a hole in one of Atlas' supports created by an explosion that has disappeared.
