25 years after the battle at Ambat, the war between the Federation and the Vagans keeps escalating with no end at sight as the Vagans rejected all offers for a peace treaty. Flit, now married and father of two is a commander of the Earth forces determined to win the war and decides that the time has come to his son Asemu to succeed him as the pilot for the Gundam, entrusting him with the AGE Device on his 17th birthday. On an attack on his city, Asemu pilots the Gundam AGE-1 hidden at the family's stable for the first time to repel the Vagan offensive.

The manga follows a slightly different storyline from the anime, though its plot remains the same.
Two separate volumes were released: a "top" (上) volume that involves the heroes and a "bottom" (下) volume that involves the antagonists.

After deploying several sleeper agents around the globe, the Vagans launch a surprise attack that finally brings the war to the Earth. To counter the invasion, Flit activates the recently completed Gundam AGE-3 and entrusts it to Kio. Just like his father and grandfather before him, Kio enlists into the Diva as part of its mobile suit squad to confront the Vagans.
