Ceres

Ceres, former no 47, halfawakened executive colonel of the Black Card Brigade which she also was a founding member of (c36). She was created from the flesh of Irayna, making her an experimental warrior. She has shown the ability to communicate directly with this implant through speaking to herself when alone. In her time in the organization, she was noted to have rebellious tendencies and was thought to be weak, suggesting she defected from the organization voluntarily.

Sharon mentioned she was gravely underestimated by the Organization and is far stronger than her rank indicates. She has the ability to synchronize her Yoki with other warriors and pull them back if they lose control over their Yoki and are in danger of awakening. She also has excellent Yoki reading skills and control (c38). Due to her half-awakening and control of yoki flows, Ceres is able to awaken her limbs, something no other Claymore has been shown to be capable of.

Ceres has only ever awakened her arm. It's awakened appearance is a slender, frail humanoid arm with sharpened fingers and a  bent saber-like projection coming out of the outside of her wrist. This saber is extremely sharp and was easily able to cut through the slug awakened's tentacles.

She sees herself as an experimental warrior and claims to know what type a warrior belongs to by investigating their stigmata. She suspects Grace to be like her in this regard and tried numerous times to have a peek at her stigmata.

Ceres is currently in Mucha, scouting out dangerous awakened.
