Sophia was Claymore No. 3 of Teresa's generation. She was demoted to No.4 when Priscilla was promoted to No. 2. Due to her immense strength. Sophia had chin-length, wavy, pale blond hair worn loose and parted in the middle, basically a shorter version of Teresa's hair. She has silver eyes like all Claymores and wore the standard uniform. She was often seen with a sultry smile on her face. Sophia's lady-like personality was a stark contrast to Noel's and was also somewhat incongruous to her abilities. She was haughty, elegant and outwardly polite to others, except for Noel, whom she always found the opportunity to mock. Many consider it ironic that Sophia has brute strength instead of supreme agility because of her elegant appearance. Sophia first appeared while clearing out a Yoma hive with Noel. The two immediately began arguing, first over who had killed more Yoma and then over who deserved the higher rank between them. The two were about to engage in a fight to determine who truly deserved the No. 3 spot when Irene arrived. Irene informed them of the mission to slay Teresa. She also introduced Priscilla, the new No. 2, to them. More than the number of Yoma slain, Sophia was astonished by the fact that she was unable to sense Priscilla when she was just fighting nearby.[1]

At the inn, Sophia was given the job of attacking from beneath, forcing her sword through the floor below Teresa. She missed, however, and watched Teresa battle Priscilla from the doorway.[3] When Priscilla started having difficulty, she joined the fray, but was struck down easily by Teresa.[4] Later, when Priscilla lost control and pursued Teresa, she followed Irene.[5] The three of them kept a safe distance while Teresa was engaged in battle with Priscilla.
