Claymore

Shapeshifting, flesh-eating demons called youma descend on Raki’s village, and a solitary silver-eyed swordswoman arrives in their wake. She is a Claymore—an engineered half-human, half-youma warrior created to hunt these creatures. After Raki’s family is slain, she spares his life, but his survival comes at a cost: he’s cast out from his home with nowhere to return.

Raki tracks down the warrior, Clare, and chooses to travel beside her as she moves from town to town, cutting down youma wherever they appear. Along the road, the truth behind Clare’s organization and the other Claymores gradually surfaces, while each battle draws her closer to the youma she has pursued for vengeance since the day she became a Claymore.
