Claymore(2001)

CLAYMORE

In a world where monsters called Yoma prey on humans and live among them in disguise, humanity’s only hope is a new breed of warrior known as Claymores. Half-human, half-monster, these silver-eyed slayers possess supernatural strength but are condemned to fight their savage impulses—or lose their humanity completely.
