Sandra was a recruit of the Survey Corps. She joined at some point after the crowning of Historia Reiss during the two months between the attack at Orvud District and the expedition returning to Shiganshina District, where she was assigned to Squad Klaus.
Sandra was an average height woman with a physically fit build. Her blonde hair was cut near shoulder length with bangs that fell over her forehead. After joining the Survey Corps, Sandra wore the standard uniform of the regiment.
During the feast before the expedition to Shiganshina District, Sandra accompanies Floch Forster as he rhetorically asks Jean Kirstein if 104th recruits and former Garrison members such as himself and his friends are unreliable.
