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

Before Suletta can take in her victory, she's surrounded and taken into custody on suspicion of utilizing forbidden GUND Format technology.

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.

Much to everyone's entertainment, Suletta panics and flees when Guel suddenly proposes to her. But Chuchu from Earth House isn't amused at all.

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

Ahead of her duel with Elan, Suletta feels confused about his change of attitude. Her housemates help her augment the Aerial for better mobility.

When Suletta receives an invitation to a social event for new business startups, she decides to attend in hopes that Elan will also be there.

Miorine wastes no time recruiting her housemates for her new company that will handle Gundams, but they must first decide on a business plan.

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.

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.

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.

Behind the scenes of the vibrant Open Campus, Suletta learns what Sophie wants to get from their duel. Nina, meanwhile, feels responsible for the situation. As they each pursue their respective desires and strategies, the Rumble Ring kicks off.

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.

The school is in chaos as a result of the Open Campus incident. The Benerit Group's coverup of the incident and its aggressive security operations on Earth have been reported to the public, and it decides to hold an election to turn the situation around.

Having learned of the connection between Prospera and Delling, Miorine decides to take over the Quiet Zero project in exchange for Suletta's liberation. Miorine's 17th birthday is imminent. Now the curtain rises on the final duel that will determine her bridegroom.

Defeated in a duel, Suletta has suddenly lost both Miorine and the Aerial. To shake off her sadness, she throws herself into school life. Miorine is getting ready for the presidential election, just as she promised Prospera. But she is clearly worried as Shaddiq takes the lead.

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...

Guel learns that Shaddiq is the mastermind behind the kidnapping of Sarius.

The Asticassia School of Technology has been devastated by Norea's rampage. The surviving students are forced to live in evacuation shelters as they wait for relief.

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.

Relationships that end and others that are formed anew. Sadness and joy. Violence and wishing for peace. Space intermingles everything as a younger generation finds its way in a world where what is right is only a matter of perspective.
