Isabel's Sister (Levi X Reader)
Isabel had a twin sister, who was 20 minutes younger, but she kept that secret to herself ever since they were split up by the two running away from home. Isabel joined up with Levi Ackerman and Furlan Church, a group of thugs in the Underground City, while her younger sister was standing next to Erwin Smith, Commander of the Scout Regiment. (Y/n), was her name, and the two sisters never saw each other ever since...
until one faithful day.
