Reika was miraculously selected as a pilot by Shennon's awakening, and finally the training for conformity with the G's frame started. However, after the night of Seven Stone City, Shennon did not start at all and Reika could not even board. Misaki and Arhena, who passed the strict aptitude test with dreams and hopes, are also confused by the hard physical training. Meanwhile, Unit 7 Pabilsaĝ, which was newly excavated from the Madain Sareha archaeological site in Saudi Arabia, arrives at the AG base. The girls' wish is "I also want to have a favorite machine." Synchro rate measurement with Pabilsaĝ has begun.
Li Xinglan wird überraschenderweise Mitglied der Ancient Girls. Doch die anfängliche Freude vergeht bald, als sie es nicht schafft, den GS-Frame noch einmal zu fliegen. Captain Judith will sie sogar aus der Einheit ausschließen. So wird der erneute Angriff der Nergal zur doppelten Bewährungsprobe.
