War of Bat Extermination

In AG 108, another colony, Ovan, was attacked by Vagan and destroyed. The first protagonist of the series, Flit Asuno survived the attack, received the AGE Device from his dying mother and went to Nora to begin constructing a mobile suit called Gundam.

In AG 115, Nora eventually came under attack. It was then Flit activated his AGE-1 Gundam AGE-1 Normal and destroyed a UE's ovv-f Gafran. UE, learning of the Gundam, sent in their colony destroyer to destroy Nora. In the same time, all Nora colonists evacuated to the colony's ejectable port and it was pulled out by Diva (under the command of rogue captain Grodek Ainoa). While the Gundam fought the Vagan forces outside the colony, a debris held the port from being evacuated, until Commander Hendrick Bruzar, the commander of Nora's Arinston base, sacrificed himself by blowing the debris in a suicide attack.

Later, Diva traveled to Fardain. There, Flit faced the ongoing battles between the remnants of Euba and Zalam, whom still fought each other even though the war was ended. During the skirmish, UE's ovv-a Baqtos came into the colony and Flit fought against it, but ended up being out powered by the much stronger Baqto and being captured by Zalam's CMS-223Z Zila, thinking the AGE-1 Gundam AGE-1 Normal as an enemy trespassing in their territory. While Flit kept convincing Don Boyage, the leader of the local Zalam forces to fight UE (Unknown Enemy/Vagan), leader of Euba forces Ract Elfamel, came for payback. Again, in the middle of the battle, the Baqtos came back into Fardain. Flit managed to convince Zalam and Euba forces to cooperate against those Baqtos and he himself headed back to protect the truck taking the children from the Baqto. It was then, the AGE system created the new equipment for the Gundam, which would later be called the AGE-1T Gundam AGE-1 Titus. With this new equipment, Flit managed to defeat one unit of Baqto, while the others were defeated by Woolf Enneacle's new WMS-GEX1 G-Exes. After the ensuing battle, Zalam and Euba came to temporary truce to protect Fardain.

When Diva was leaving Fardain with several Zalam and Euba warships, they faced a Vagan's Fa Bose. Zalam and Euba MSs were no matched for Vagan's MSs while Diva had to deploy their forces to destroy those enemies units. In the middle of the battle, Woolf and Flit faced a black transformable MS, xvv-xc Zedas which once appeared during Nora's evacuation. Zedas had fast movements and tricked Zalam and Euba into hitting each other. Don Boyage, realised with Flit's words of fighting together, decided to sacrifice himself to ensure both Zalam and Euba forces worked together with Diva forces to protect humanity. His sacrifice left a lot of lessons for those forces to fight together against Vagan. Also in the battle, AGE system produced yet another new equipment, AGE-1S Gundam AGE-1 Spallow to match up with Zedas's speed. After the long battle, Vagan forces retreated with the Diva and Euba-Zalam Alliance, now under Ract's command, marched to Minsry to gather the remaining Euba and Zalam forces.

In Minsry, Earth Federation Forces 8th Space Fleet, Special Detachment forces under command of Stoller Guavaran was tasked to arrest Grodek and Diva for discipline violation. However, the 8th Fleet was under attack by Vagan. Diva and the Zalam-Euba warships protected the 8th Fleet and forced the Vagan to retreat. The 8th Fleet then let the Diva go to "protect the humanity". Once Diva arrived at Ambat, each sides launched their MSs. This time, Diva forces, Zalam and Euba forces were equipped with more effective weaponries and managed to defeat Vagan's MSs. After the initial strategy succeeded, Diva shot her new Photon Blaster Cannon installed by Mukured Madorna through blueprint from the AGE Builder under the permission of Grodek himself and destroyed the UE Mothership. At the same time, Flit faced xvb-xd Farsia piloted by Yurin L'Ciel whom was forced by Desil, who also joined the battle. When Flit's AGE-1 Spallow was heavily damaged by Desil's attacks and about to take his blow, Yurin sacrificed herself. In rage, Flit crushed Desil's Zedas, but showed him a mercy because of Desil’s tearful pleads. Flit then changed to Gundam AGE-1 Titus to open the Ambat's dock for Diva and changed back to AGE-1 Normal. Inside Ambat, Vagan's footmen fought against Diva's footmen for their last stand while Flit, with his X-Rounder ability, defeated Geera's xvm-gz Defurse. Geera retreated to his command room and revealed to Diva's forces of their real intention and who they really are. Flit, feeling angry over the death of Yurin and his mother, wanted to shoot Geera but Geera was shot by Grodek instead. Arabel, having found out his father was mortally shot, wanted to avenge his father, before being haunted by Grodek's word. After Geera threw out his last breath, the remaining forces set off a self-destruct mechanism to blow up Ambat. Diva crews managed to return to their ship in time and rendezvous with remaining forces and evacuated Ambat. After the battle, Grodek surrendered himself to EFF command for discipline. EFF, hoping to get the support from the public opinions, covered up the truth of the Diva's operation: They claimed that Diva acted independently in behalf of EFF (in fact, Diva acted independently by its own crew's wishes, not by the command of EFF) and defeated UE in Ambat. The truth about UE was revealed, but only as a nation in Mars which named Vagan and EFF didn't reveal the origin of Vagan to the public.
