Nullitas, always a child at heart, was raised as a boy until her world was shattered. She served the Romagnolo family as a dreamy seventeen-year-old with aspirations of becoming a knight, until her mother revealed a surprising truth. After experiencing her first menstrual cycle, Nullitas discovered that she was, in fact, a girl. Her mother had hidden this fact from the Count, who used Nullitas to protect his true daughter, Maylene. With a newfound identity, Nullitas, who was previously nameless, was christened with a title that described her feelings towards her new reality: "Nullitas," meaning "nothing." Her life was forever changed.
