Kurz vor dem Niederschlag kann das zweite Team von Celestial Being die Gundam Meister retten. Das Team entpuppt sich als Johann, Michael und Nena Trinity, die Meister des geheimen Gundam Thrones.
Three new mobile suits, piloted by a trio of siblings, appear on the battlefield and reveal themselves as Gundam Throne Eins, Zwei, and Drei. Caught off-guard by the new Gundams' sudden arrival, the Union, AEU, and HRL forces are decimated and forced to retreat. In order to secure a route of escape, Gundam Throne Drei covers the entire region in GN particles, causing havoc with enemy communications and preventing a counterattack. After escaping from the Taklamakan Desert, the rescued Gundam Meisters are anxious about the new units and disturbed about not knowing of their existence. While world leaders despair at the appearance of the new Gundams, Alejandro Corner attends an anonymous conference with the other Celestial Being "observers" to review Celestial Being's activities and to discuss the acknowledgement of the Gundam Thrones. Aboard their spaceship, the Trinity siblings fly to meet the Ptolemaios to greet the Gundam Meisters.
À la stupeur générale, les quatre Gundam qui étaient sur le point d'être capturés se font sauver par trois nouveaux appareils fonctionnant également aux particules GN. Ce retournement de situation sauvant les Meisters de justesse pousse chaque camp à faire le bilan de l'arrivée mondiale de Celestial Being.
