The Asticassia School of Technology is run by the Benerit Group, a major player in the world of space industry. Suletta Mercury, a transfer student from the planet Mercury, is looking forward to her new life at the school. But just as she is about to arrive, she notices a lone figure drifting in space.

Suletta has won in her combat with Guel. However, there are now suspicions that her mobile suit Aerial uses the GUND Format, a forbidden "witch's technology." Meanwhile, Miorine faces a crisis as her father Delling wants her to leave the school.

Suletta is being forced to duel in a rematch. She and Miorine form a cooperative partnership to save the Aerial from being scrapped, and keep Miorine from being expelled from school. But for her opponent Guel, this is also a battle he absolutely cannot lose.

Bewildered by Guel's sudden proposal, Suletta panics and flees from the scene. Everyone is astonished by Guel's behavior, but Chuchu, a student from Earth House, stares at him with cold indifference.

Peil Technologies has sent Elan to reveal the secrets behind Aerial. Suletta had Elan in her mind, because of his benevolence. One day, Elan asks Suletta to go out with him.

Suletta has agreed to a duel with Elan, but she can't hide her bewilderment at Elan's sudden change of attitude. The duel is to take place in space outside the front, and since the Aerial has no thruster unit, she is forced to upgrade her machine.

As Suletta passes her days in a state of distraction, unable to get in touch with Elan, a letter arrives from the Benerit Group inviting her to an incubation party. Though Miorine dismissively tells her that she doesn't need to go, Suletta is hoping that she can see Elan again...

GUND-ARM, Inc. has been hastily launched. Now Miorine, who has become the company president, is enlisting the members of Earth House as employees. But due to its rushed creation, the nature of the business has yet to be decided. Seeking a way to lift the Gundam's curse, Miorine pays a visit to Prospera.

The launch of GUND-ARM, Inc., has been stalled by Shaddiq's scheming. Miorine challenges him to a duel, with the fate of the company at stake. The terms of the duel are a six-member team battle. But Earth House doesn't have that many mobile suits, or pilots...

It has been two months since the duel with Shaddiq. Little by little, the launch of GUND-ARM, Inc. is proceeding on track. As she juggles the company and her schoolwork, Suletta's days are productive and fulfilling. Meanwhile Miorine, pushing forward in her demanding role as company president, unexpectedly encounters Feng once again.

The members of Earth House depart the school to pick up the Aerial, which has been under repair. Their destination is Plant Quetta, a giant development facility that belongs to the Benerit Group. But Suletta is still troubled by the misunderstanding between her and Miorine.

Plant Quetta has been attacked by a pair of Gundams. Miorine, separated from Suletta, runs through the facility in an attempt to rejoin her. Meanwhile, Suletta marches forward to save Miorine.
