Sandy is the main character of Earth Chapter. Because she is the daughter of Dr. Grey Newman, the discoverer of the ruins on the Moon, she feels a certain degree of responsibility for the destruction wrought by the MME. A gentle woman by nature, the struggle for survival has hardened her. Rather than give in to cynicism as so many have, Sandy retains her idealism. She fights with firm resolve and by the beginning of the story has risen to the level of a minor officer in the resistance movement. Is is she who forces the leader of the MME to face the truth it cannot bear to see at the climax of the story.
