Rosemary was Claymore No. 1 of her generation but was demoted to No. 2 upon Teresa's promotion.[1] She was also Claymore No. 4 of Hysteria's generation.[2] As a Claymore, Rosemary had short, light-colored hair, with the fringe swept to the left side of her forehead. Just like other typical Claymores, she had a pair of silver eyes and wore the standard uniform. Rosemary appeared to be a serious Claymore who took immense pride in her No.1 ranking until Teresa stripped her of that title. Despite her outward acceptance, she secretly despised her successor. Rosemary was Claymore No. 4 of Hysteria's generation and was part of the infamous Rockwell Hill incident in which Hysteria, then Claymore No.1, refused to submit to execution and slaughtered the warriors sent to hunt her.[3] Rosemary was the one that managed to land the finishing blow altough that was because of the effort of Teresa to take away Hysteria's speed advantage.
