A shy girl from Mercury enrolls in the prestigious Asticassia School of Technology and immediately bumps heads with top student Miorine Rembran.

Miorine insists on helping Suletta in her rematch against Guel. But with his pride in tatters, Guel has no intention of losing a second time.

Hoping to uncover the Aerial's secrets, Peil Technologies orders Elan to investigate Suletta, who gets flustered when he invites her on an outing.

The Earth House members arrive at Plant Quetta to retrieve the refurbished Aerial. Suletta worries about the misunderstanding between her and Miorine.

Suletta has to change her attitude if she's going to save Miorine and everyone else. Meanwhile, Miorine and Guel will fight to survive.

Pursued by the Benerit Group's garrison forces, the Dawn of Fold which perpetrated the attack on Plant Quetta is forced to evacuate its hideout. Guel, who was captured by Olcott, is now a prisoner at the hideout. Having slain his own father, Guel remains sunk in deep despair.

Piloting the Calibarn, Suletta confronts Ericht head-on. Guel squares off against Lauda, who is burning with bitter hatred for Miorine. And amid the chaos of battle, a rocket carrying Miorine and the others makes its way to Quiet Zero.
