Teresa, a powerful Claymore, saves a young girl from her bandit captors and leaves the child in the care of some villagers. But triumph quickly gives way to despair when the situation takes a tragic turn, and Teresa is forced to kill a human–an act that will condemn her to death at the hands of her own kind.
A Claymore - a female warrior named for the sword she carries - travels from medieval village to village to destroy Yoma, monsters who disguise themselves as humans and who are almost impossible to kill. Claymores are half-humans, half-demons who willingly transformed themselves by mixing their blood with monster’s blood. Claire, nicknamed silver-eyed killer, is such a powerful Claymore, she can slay a Yoma using only one hand. But she must constantly struggle to keep from becoming a monster herself.
