Miorine rejects Shaddiq's business offer and challenges him to a duel. They agree on a team battle, but her side lacks mobile suits and pilots.

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

It has been two weeks since the attack on Plant Quetta. At first glance, it seems daily life at the school has remained peaceful, but a gag order has been imposed regarding the incident, and the members of Earth House feel suffocated. As preparations get under way for the next day's Open Campus event, a pair of transfer students appear before Suletta.

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.

Descending to Earth with the Aerial, Miorine holds discussions with the Earthians leading the protests. Given the grim situation on the ground, it seems peaceful negotiations will be almost impossible. Meanwhile, the members of Earth House are unable to cheer up the despairing Suletta...

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.
