オーブにて再会を果たすキラとアスラン。直面する大切な仲間の死。そして変わり行く戦局の中アークエンジェルが選ぶ道とは…?
It's been 70 years since the Coordinators, a technologically advanced species, and the Earth Alliance, a purely human troupe, have existed together side by side. Tension worsens as the Alliance learns that the Coordinators have been working on Gundam suits that will leave them further in the dust. Salvation comes in the unlikely form of Kira Yamato, a Coordinator who empathizes with the Alliance's plight.
