When Claire was a child, she met Theresa, the strongest Claymore. To save Claire, Theresa broke their iron rule to kill a human. Because of breaking the rules, she was wanted by punitive group. Pricilla, a member of the punitive group, couldn't control the power of the magical sword, and turned into an "Awakened". Then, Theresa was beaten by the large power of Pricilla.
