In the year 2311 AD, a world that once saw itself full of inter-continental conflict now stands unified, led by the Earth Sphere Federation (ESF). The ESF established a preventative military task force known as the A-Laws, tasking them with shutting down violent terrorist organizations. As they gain more and more legal authority, the A-Laws begin to twist the law to fit their own agenda, ruling the citizens of Earth with a heavy hand. In response to the fascistic behavior of the A-Laws, the anti-terrorist group Celestial Being reappears. Led by state-of-the-art mobile suits known as Gundam, the pilots of Celestial Being wage a new war with the A-Laws, aiming to stop their tyrannical abuse of power. Setsuna F. Seiei, pilot of the Gundam Exia, helps to lead the charge along with his fellow Gundam Meisters Lockon Stratos, Allelujah Haptism, and Tieria Erde. But in the process, Setsuna stumbles upon a conspiratorial plot spearheaded by a new faction, the Innovators, and must contend with his own old wounds and ghosts of the past in order to save a world that despises him.

Eighth-grader Shigeo Mob Kageyama has tapped into his inner wellspring of psychic prowess at a young age. But the power quickly proves to be a liability when he realizes the potential danger in his skills. Choosing to suppress his power, Mob's only present use for his ability is to impress his longtime crush, Tsubomi, who soon grows bored of the same tricks. In order to effectuate control on his skills, Mob enlists himself under the wing of Arataka Reigen, a con artist claiming to be a psychic, who exploits Mob's powers for pocket change. Now, exorcising evil spirits on command has become a part of Mob's daily, monotonous life. However, the psychic energy he exerts is barely the tip of the iceberg; if his vast potential and unrestrained emotions run berserk, a cataclysmic event that would render him completely unrecognizable will be triggered. The progression toward Mob's explosion is rising and attempting to stop it is futile.

In A.G. 101 (the 101st year of the Advanced Generation calendar) a mysterious entity known only as UE, or unknown enemy, attacks and destroys the space colony Angel. This brutal attack becomes infamous as the The Day the Angel Fell, and marks the beginning of humanity's war for survival. The series begins in A.G. 108 when the UE attack the space colony Ovan, where Flit Asuno lives with his mother. Flit's mother is killed by the UE, and in her belongings (in an object called a AGE Device) he discovers the blueprints for a powerful weapon from the past - the ancient messiah named Gundam. From these blueprints, Flit spends the next several years studying engineering at an Earth Federation base on the Nora space colony and designing the AGE-1 Gundam. Seven years later, in A.G. 115, Flit completes the Gundam, just as the UE attack Nora. Flit and his lineage's battle piloting the AGE-1 to protect mankind is about to begin. (Source: GoodAnime.net)
