A girl with long flaxen hair, wearing glasses and a white lab coat. She wears tights. While her outfit changed slightly in the first game upon moving to Dawn, it remains the same in the sequel. In Genocide Mode, her glasses come off and a headpiece resembling a bird's head covers her. In Blood Skelter Mode, giant hands appear wielding a scythe. She is a typical high-functioning, logic-driven STEM personality, lacking in emotional expression and possessing intense intellectual curiosity. She rarely feels more than clinical interest toward others, acting more like a mad scientist than a psychopath. She seems to enjoy human interactions from an observer's standpoint, but this detachment extends to herself; she would not hesitate to sacrifice her own life if she judged it to be the optimal solution. She shows very little emotion through facial expressions and is almost entirely unresponsive.
