An elite team of special agents faces off against an ancient and bizarre race of creatures whose millennia-long attempt to enslave humanity have given rise to man’s ancient legends of shape-shifting monsters and demons!

For over one thousand years, the forces of the Aragami have been held in check by a steady diet of human sacrifices, but now the bonds have been broken and its up to the elite agents of the TAC to take on mankind’s oldest enemies, whose ability to impregnate, mutate, and control almost any living creature make them the most deadly of adversaries.

To combat an enemy who can attack anywhere, anytime, without notice will require the most talented agents from around the world and every resource modern civilization can provide, from high-tech super-computers and chemical weapons to plain old bazookas.

The most dangerous items in the TAC’s arsenal, however, are the two special human weapons. Joining the agents in their battle are Momiji Fujimiya, a young Japanese teenager whose traumatic implantation with an unborn Aragami, a “blue seed”, has left her with enhanced psychic abilities, and Mamoru Kusanagi, orange skinned, cat-eyed former servant of the Aragami who rebels against the will of his masters to use his super-human powers to protect Momiji!

The ultimate destiny of the planet earth will be decided once and for all!
