Formerly known as Sharon Kreuger, the Severing Chains, she served Chairman Irina as the Reinford family's maid. She used her skills to support Class VII through many of their adventures.

Due to the freedom she was granted as an Enforcer, she had been taking an extended leave from Ouroboros. However, with Alberich's reappearance, her contract with Irina ended and she discarded the name "Sharon" and returned to the society.

Now she stands on the opposite side of the battlefield, facing down Alisa and her friends with an icy gaze.
