機動戦士ガンダムAGE 〜始まりの物語〜

Flit Asuno opens the Advanced Generation story here, across two chapters published as the Gundam AGE television series began. Centuries of settlement among the space colonies had produced a peace that did not hold; an enemy nobody could name broke it, and the war that followed has run a hundred years. This short tie-in lays out that premise rather than carrying a story of its own.
