Sachie Murata (村田 幸江, Murata Sachie) is a female character distinguished by her blue shoulder-length hair and blue eyes. She wears glasses, stands 1.55 meters tall, and has body measurements of 74-57-92. Her signature attire consists of a maid outfit complete with a headdress, tie, gloves, and thigh-high boots.

Sachie exists within a system where enslaved women are treated as objects controlled by Renji Hishimi. Among them, she endures especially harsh treatment. Despite this oppressive environment, she secretly befriends another character named Yuu. Renji Hishimi discovers this act of defiance and, refusing to tolerate any autonomy, personally executes Sachie as punishment.
