In A.G. 101, The war between the Earth Federation Forces and an Unknown Enemy would begin when the latter destroyed the space colony Angel, a tragedy that would later known as "The Day the Angel Fell." 7 years later, when the colony Ovan was being attacked by the UE, Flit Asuno's dying mother provided him with their family's heirloom, the AGE Device, which contains schematics for a legendary Mobile Suit known as "The Gundam." Having spent the next 7 years working to develop a weapon in its image, he soon must put it to the test when a fleet of UEs invades his new home colony Nora, threatening the lives of his friends.
