Rosemary

Rosemary was Claymore No. 1 of her generation but was demoted to No. 2 upon Teresa's promotion.

Etymology
"Rosemary" is a transliteration of the Japanese "Rozumari" (ローズマリー, pronounced "rOz-mah-rEE," similar to "Rosemarie").

"Rosemary" was a word introduced in the mid-15th-century (earlier rosmarine, c.1300), from the Latin rosmarinus, meaning "dew of the sea," from ros "dew" + marinus "of the sea." It could also have been derived from "rose" + "Mary."

Claymore
As a Claymore, Rosemary had short, pale blonde hair, with the fringe swept to the left. She had silver eyes and wore the standard uniform.

Awakened Being
Rosemary's size increased dramatically upon awakening. She developed two arms, four wing-like appendages, six crab-like legs, a large tail, and an eyeless head. She also had two head-like protruberances with large mouths on either side of her hips. Rosemary's real body was merged with the chest, with only her head, torso, and proximal arms and thighs visible.

Personality
Rosemary is distraught over the loss of rank No. 1. She despises her successor and even awakens to kill her, in order to prove she is stronger than Teresa.

Employment as a Claymore
Rosemary was Claymore No. 1 until Teresa took her place. Demoted to No. 2, she sought revenge and planned on eliminating Teresa.

Awakening


After completing a mission, Teresa received Rosemary's black card from Orsay. She was puzzled, to say the least, as she had never come in contact with Rosemary.

Teresa set out and arrived at the designated spot, Godahl Plateau. Upon her arrival, Rosemary apologized briefly, then attacked Teresa.

After a clash of swords, Rosemary transformed into her awakened form. She admitted that the black card was a trap and that she had awakened prior to sending the card. Teresa, much to Rosemary's surprise and irritation, said she was relieved that she was going to kill an Awakened Being and not a human.

The two clash, Rosemary seemingly gaining the upper hand briefly. She grabbed Teresa and rammed her into a boulder repeatedly, all the while claiming that the Organization had made a mistake in giving her, Teresa, the top spot. After a while, Teresa freed herself by ripping off Rosemary's arm with ease. Teresa released 10% of her yoki, frightening Rosemary by its sheer enormity. Before Rosemary could even react, Teresa moved forward swiftly and sliced Rosemary to pieces. Before dying, Rosemary called Teresa a monster, to which Teresa replied, "That makes two of us."

Her task done, Teresa reported back to Orsay. Orsay noted the state of Teresa's clothes and wondered if Teresa had defeated an awakened Rosemary. Teresa lied, reporting to Orsay that she killed Rosemary before the latter awakened and that Rosemary's final moments were fitting for a former No. 1.

Teresa
Though Rosemary pretended to accept her demotion to No. 2, she in fact harbored an intense hatred for Teresa to the point that she willingly awakened just to have the chance to kill Teresa.
