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.

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.

GUND-ARM Inc. gradually gets on track thanks to the efforts of Miorine and her employees. Shaddiq begins orchestrating a plot to assassinate Delling.
The Earth House members arrive at Plant Quetta to retrieve the refurbished Aerial. Suletta worries about the misunderstanding between her and Miorine.
Separated from Suletta amid the Dawn of Fold's assault on the plant, Miorine tries to make her way back to her but runs into her father, Delling.
Normal school life resumes after the attack on Plant Quetta. Amid preparations for an open campus event, Suletta encounters two new transfer students.
The students participate in an exhibition battle during the school event, but the fight is soon interrupted by a pair of familiar mobile suits.
While holding Guel captive, the Dawn of Fold prepares to evacuate its compromised hideout as the Benerit Group's security forces draw closer.
Facing pressure in response to its recent activities, the Benerit Group decides to elect a new president. Miorine finally returns to school.
Miorine agrees to take over the Quiet Zero project if Prospera leaves Suletta out of it. Later, she asks Guel and Suletta to duel for her birthday.
Miorine begins preparing for the Benerit Group leadership election, but she's taken aback by how quickly Shaddiq is shoring up support.
With the Aerial in tow, Miorine arrives on Earth to negotiate with the protest leaders, who begin the talks by making an unacceptable demand.
