Spriggan

Humanity has inherited ruins left by an ancient civilization whose technology became powerful enough to destroy its creators. To keep those relics from being turned into weapons again, ARCAM sends elite agents known as Spriggans around the world to seal them away.

When an extraordinary structure believed to be Noah's Ark is uncovered in the Ararat Mountains, Spriggan Yuu Ominae is drawn into a race for control of it. A special American military force led by the unnaturally gifted Colonel MacDougall attacks the site, determined to claim the Ark's power. Jean Jacquemondo, another Spriggan, joins Yuu in trying to halt the assault before a remnant of the ancient world becomes a modern catastrophe.
