At Fólkvangr, a front constructed inside an asteroid, the Gundam Lfrith is undergoing operating tests in the Vanadis Institute's laboratory. The Lfrith has not yet managed to meet the conditions imposed by the council, and test pilot Elnora Samaya is growing impatient. That same day, her daughter is celebrating her fourth birthday...

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.

It has been two months since the duel with Shaddiq. Little by little, the launch of GUND-ARM, Inc. is proceeding on track.

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.

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...

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.

Prospera and Ericht activate Quiet Zero.

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.
