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 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.

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

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.

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

Prospera and Ericht activate 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.
