Spriggan (ONA)

An ancient civilization left behind artifacts and technology far beyond modern science, and every discovery triggers a race among governments and armies eager to claim that power. ARCAM takes a different position: seal the relics away and prevent anyone from turning them into weapons, using elite agents known as Spriggans to enforce that mission. Yu Ominae is one of them, a student on the surface and an enhanced operative when duty calls. From Noah's Ark hidden near Mount Ararat to other ruins capable of changing the balance of the world, Yu faces mercenaries, superhuman opponents, and nations that see the past only as a tool of domination. His job is not to possess ancient power, but to ensure nobody else does.
