She is the twin sister of Sophie and the adoptive sister to Tennessee. She was a supply runner at Ericson's Boarding School before Marlon agreed to trade her and Sophie to the Delta. Following the trade, Minerva chooses to remain at the Delta to help serve as a soldier.

Minerva was described as being a creative and musical person by Violet. After joining the Delta, however, she has a much more hardened personality and was led to believe that siding with the Delta is better.
