The Witch from Mercury

At Fólkvangr, a front constructed inside an asteroid, the Gundam Lfrith is undergoing operating tests in the Vanadis Institute's laboratory. The Lfrith has not yet managed to meet the conditions imposed by the council, and test pilot Elnora Samaya is growing impatient.That same day, her daughter is celebrating her fourth birthday...

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.

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.

As war erupts, Suletta must choose to pilot Aerial, risking all to save her friends.

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 battle royal-style dueling event known as the Rumble Ring kicks off.

Pursued by the Benerit Group's garrison forces, the Dawn of Fold which perpetrated the attack on Plant Quetta is forced to evacuate its hideout. Guel, who was captured by Olcott, is now a prisoner at the hideout. Having slain his own father, Guel remains sunk in deep despair.

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.

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.

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.

Descending to Earth with the Aerial, Miorine holds discussions with the Earthians leading the protests. Given the grim situation on the ground, it seems peaceful negotiations will be almost impossible. Meanwhile, the members of Earth House are unable to cheer up the despairing Suletta...

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

The Asticassia School of Technology has been devastated by Norea's rampage. The surviving students are forced to live in evacuation shelters as they wait for relief.

Prospera and Ericht activate Quiet Zero.

Piloting the Calibarn, Suletta confronts Ericht head-on. Guel squares off against Lauda, who is burning with bitter hatred for Miorine. And amid the chaos of battle, a rocket carrying Miorine and the others makes its way to Quiet Zero.
