Cassandra

Cassandra was Claymore No. 1 of her generation and is considered to be one of the eight most powerful Claymores of all time. During her lifetime, she was known as "Cassandra the Dust Eater." She is one of the three Claymores revived by Dae and the Organization in order to stop the uprising of the current warriors. Cassandra seems to be self-conscious, modest, even shy, and is easily embarrassed, as seen when she blushed and averted her eyes when Roxanne complimented her. She was also stubborn in refusing to allow other warriors to accompany her when hunting for Awakened Beings, most likely because of her technique, which often soiled her face and made her look as if she were eating dirt.
