In a world that is trying to cope with artificial soldiers left over from the war, Agate Fluorite transfers to the prestigious Cluster Edge Academy – a recognized starting point for leaders of the past and the future. He’s naïve, optimistic, and from no apparent background; but more than that, there’s something very different about Agate: he has the power to make “miracles” happen. Meanwhile, the artificial soldiers working with former Cluster E.A. student Chalce rebel at news of his death. Led by Chalce's younger brother Chrome, they attempt to destroy the remaining artificial soldier plants and take on the military in his name. In their journey to understand and become human, they cross paths with Agate and his new Cluster E.A. friends, and are pulled into the havoc caused by the military who want Agate's power. It is only a matter of time before one side discovers the truth behind Agate…
In the world of Prestal, Noble men perform noble deeds for noble purposes. All of this is performed under the careful gaze of the Guild, a race apart who live in cities in the sky. We see this world through the eyes of Claus Valca and Lavi Head, as their travels take us above, beyond and through Prestal, and their actions cause ripples that shall never fade.
Both Last Exile and Cluster Edge are set in an alternate and fantastical universe. A good action/adventure romp, featuring kids being thrust into a military encounter and fighting to keep the world as they know it.
Both have some interesting air-ships, although Last Exile has much more visually stunning animation. There are also some morally difficult questions posed, meaning these shows are definitely better suited to a more mature audience.
