Rosemary

Rosemary was Claymore #1 during Teresa's time. She was demoted when Teresa became the new #1 warrior, which sparked a furious anger in her.

Appearance
As a Claymore Rosemary had short hair, with the fringe swept to the left. She wore the traditional Claymore uniform.

As an Awakened Being Rosemary's height increased to at least twice that of Teresa. She had two arms, six crab-like legs and a large tail. There was also two large mouths on her hips. She also had what appeared to be a head with large teeth, but no eyes. It also had four long appendages on its back. Rosemary's real body was attached to what would be the creatures chest. Only her torso and head was visible, with the rest connected to the larger body.

Employment as a Claymore
Rosemary was Claymore #1 for The Organization until Teresa joined. She was demoted to #2 and, while she acted like she accepted the decision, she really harboured a real hatred and jealousy for Teresa. She hated Teresa so much that she decided that she would kill Teresa, no matter what the cost, so she began to form a plan.

Awakening
Rosemary sent her Black Card to Teresa and waited in the Godahl Plateau for Teresa to arrive. By this time she had already Awakened, presumably giving her the power that would rival that of an Abyssal one.

When Teresa arrives Rosemary immediately attacks her. They had a short sword fight, however Teresa was able to block and dodge all of Rosemary's attacks easily. Rosemary then Awakens before Teresa, admitting that she had used the Black Card as a trap. Teresa says she is relieved that Rosemary hadn't Awakened because she took so long, but Rosemary seems unable to accept that Teresa was really relieved. She attacks Teresa with her tail and then smashes her into a mountain before mocking her for being weak. She again rants about being demoted until Teresa mocks her by saying it was because she was much stronger than Rosemary. Rosemary attacks again but Teresa moves quickly and twists off on of her arms. Rosemary is amazed how easily Teresa twisted her arm off but goes to attack again. Teresa begins to release her Yoki and Rosemary stops in her tracks, confused at the large amount of Yoki being released despite her only actually releasing 10% of her Yoki. Teresa then moves forward swiftly slicing Rosemary in two. As Rosemary dies she calls Teresa a monster, to which Teresa replies 'that makes two of us.'

Teresa later tells Orsay that she killed Rosemary before she Awakened and that Rosemary's final moments were fitting for a former #1.

Personality
Rosemary was very proud of being #1 and was determined to keep her rank. She is left with nothing for contempt for her replacement and even goes as far as to Awaken just to kill her, in order to prove she is the strongest. While in her quest for revenge she seemed to be ready to do whatever she had to get that revenge.
