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.

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.

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.

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.

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.
