Claymore

In a world plagued by shape-shifting demons known as Yoma, humanity's only hope lies in the hands of the Claymores—female warriors who are half-human, half-Yoma. These silver-eyed slayers are created by a mysterious organization to hunt down Yoma for a fee. The story follows Clare, a Claymore with a personal vendetta, as she battles both external monsters and internal struggles to retain her humanity.
