โมบิลสูทกันดั้ม AGE

In A.G. 101, on "The Day the Angel Fell," Flit Asuno's dying mother provided him with the schematics for a legendary Mobile Suit known as the "Gundam." Having spent the next 14 years working to develop this weapon, he soon must put it to the test when a fleet of U.E.'s invade his colony Nora and threaten the lives of his friends.

The U.E. attack of Nora has left the colony in imminent collapse. The Federation commander of the colony, Hendrick Bruzar, came up with a plan to use the flagship battleship, Diva, to save the colony core, thereby enabling the colony inhabitants to escape the destruction. However, the captain of the Diva has other plans. Meanwhile, Flit tries to escape the colony while piloting the Gundam, but comes upon a stranded girl named Yurin, who seems to have mysterious powers of her own.

Diva was preparing to pull Nora's Core when two new UE approached them so Grudeck decided to confront them first before resuming the operation. The new UEs proved to be a formidable opponent to Flit who started losing his temper but Yurin calmed him down while helping him come up with a plan to effectively take down their opponent. One of the two UEs entered Nora and attacked the control base where Bruzar was located, badly injuring him in the process. Flit is fighting the remaining UE to distract him away from Diva, but when the DOTS rifle's ammo was depleted he stopped the UE by shielding the Gundam in front of Nora and told the UE that he won't let the citizens harmed. To his surprise the UE left. Diva was about to pull the Nora's Core when an large metal debris hindered the core from moving, so Bruzar sacrifices himself by piloting an MS carrying explosives to blow up the debris hindering the core, leaving his hope to Flit and the crew of Diva, Afterwards, Nora was completely destroyed but the core was saved and Diva crew mourning the loss of Bruzar, Flit and Yurin parted but not without Yurin giving her ribbon to Flit in hopes that they'll meet again.

Federation ace pilot Woolf Enneacle wakes up from healing sleep aboard the Diva. He tries to claim the Gundam for himself to Flit's chagrin, and decides to have a mock battle to determine who should pilot the mobile suit. However, during the mock battle, the two of them are suddenly attacked by the UE, and end up making a startling discovery about how the UE are able to remain hidden.

Diva docks at the space colony Fardain. The Federation planned on arresting Grodek and having him court-martialed but he managed to blackmail the officer in charge. There Flit meets a young boy who steals the Gundam and attacks several UE mobile suit type forces with it. The boy then returns the Gundam back to Flit and leaves. In another section of Fardain the boy is met by several hooded men who explain that he is a part of the group of people "chosen by Eden".

The crew is given leave at Fardain. Grodek meets with a shady character Boyage in order to recruit more people to fight against the UE. Flit, Emily, and Dique went to explore the colony and was caught in a battle between Zalam and Euba. Complications arised and Flit launched in the gundam to break up the fight between the two forces. Just as Flit stopped the two forces, a new UE mobile suit attacked. Flit was arrested due to the collateral damage caused by the Gundam and UE mobile suit.

Flit, imprisoned by Zalam for the destruction he wreaked, is brought before their leader Don Boyage. Flit argues that Zalam and Euba should cease their feud over control of Fardain, but is rejected by Boyage. Then, Euba's boss Ract Elfamel attacks at the lead of a mobile suit squadron. Another war breaks out within the colony. Flit stands forth in the Gundam to prevent it, but a U.E. assault sparks a three-sided battle. Unable to use beam weapons inside a colony, the Gundam takes on a new form to stand up to the U.E.

To take down the U.E. that have infiltrated Fardain, Flit fights in the Gundam's new form: Titus. What the Titus loses by abandoning its Dodds rifle, unusable in colonies, it more than makes up for in brute force. Meanwhile, doubts remain between Zalam and Euba, and clashes erupt as they come together on the battlefield. As the situation becomes more desperate, Flit fights to unite the clashing Zalam and Euba elements under one banner. A new mobile suit rises on the battlefield. Who pilots its alabaster form?

Flit questions Woolf about the source of the new G-EXES. Woolf confesses and leads Flit to his old haunt, the Madorna Factory. Flit is amazed by the range of mobile suits under construction. But then, a shocking sight! Among the other models is a U.E. mobile suit! Flit and company are astounded. Just then, the U.E. suit activates and begins to destroy the contents of the factory. Flit and Woolf fight together against it, but cannot resist its fierce attacks...
