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.

슬레타는 구엘과의 결투에서 승리하지만, 자신의 모빌슈트인 에어리얼에 금지된 마녀의 기술 건드 포맷이 사용됐다는 혐의를 받게 된다. 한편 미오리네는 아버지인 델링에 의해 퇴학 위기에 처한다.

슬레타는 강제로 재결투를 하게 된다. 에어리얼의 폐기와 미오리네의 퇴학을 막기 위해 두 사람은 힘을 합치지만, 결투 상대인 구엘 역시 절대 이 싸움에서 질 수 없다.

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.

엘란을 이용해 에어리얼의 비밀을 파헤치고자 하는 페일 테크놀로지스. 슬레타는 자신에게 상냥하게 대해 주는 엘란이 신경 쓰인다. 그러던 어느 날 엘란이 밖에서 만나자고 권유하는데.

엘란과의 결투를 승낙한 슬레타. 돌변한 엘란의 태도에 슬레타는 혼란스러운 마음을 숨기지 못한다. 결투 장소는 프론트 외 주역. 추진 유닛이 없는 에어리얼은 기체 강화가 불가피하다.

엘란과 연락이 닿지 않아 망연히 하루하루를 보내던 슬레타에게 베네리트 그룹의 인큐베이션 파티 초대장이 도착한다. 미오리네는 갈 필요 없다며 잘라 말하지만, 엘란과 다시 만나고 싶었던 슬레타는…….

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.

샤디크의 계략으로 난항을 겪게 된 주식회사 건담. 미오리네는 회사의 운명을 걸고 샤디크에게 결투를 신청한다. 결투 조건은 6 대 6 단체전. 하지만 지구 기숙사에는 모빌슈트와 파일럿이 부족한데.

샤디크와의 대결로부터 2개월이 흐르고, 점차 궤도에 오르기 시작한 주식회사 건담. 사업과 학업을 병행하며, 슬레타는 충실한 나날을 보내고 있었다. 한편 미오리네는 바쁜 사장 업무에 매진하던 중 예상치 못하게 펑과 재회하는데.

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.

플랜트 쿠에타를 습격한 2기의 건담. 슬레타와 떨어져 버린 미오리네는 합류를 위해 시설 속을 달린다. 한편, 슬레타는 미오리네를 구하기 위해 앞으로 나아간다.

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.

에어리얼과 함께 지구로 내려온 미오리네는 시위를 주도하는 어시언과 대화를 시도한다. 치열한 현지의 모습이 평화적 협상은 어려울 거라고 말해주는 듯한데... 한편, 지구 기숙사 학생들은 실의에 빠진 슬레타의 기운을 북돋아 주는 데에 실패한다.

새리우스 납치 주모자가 샤디크임을 알게 된 구엘. 아버지인 빔을 함정에 빠뜨린 샤디크에게 분노한 구엘은 증거를 잡기 위해 학원으로 급히 돌아간다. 한편 샤디크는 새리우스를 이송하며 구엘에게 반격할 준비를 갖추고 있었다.

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.
