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.

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.

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.

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.
