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.

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.

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.

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

Prospera and Ericht activate Quiet Zero.
