Major General Olivier Mira Armstrong is the elder sister of Alex Louis Armstrong and commands Briggs, the northern military border. She dismisses the notion of "equivalent exchange," believing instead in the law of "survival of the fittest." Her subordinates are fiercely loyal, but she has instructed them to prioritize the survival of Briggs or the greater good over her own life if necessary. She would not hold any resentment towards them for doing so.
As the General of Briggs, Olivier holds complete command over the fortress. She is highly skilled with her family's heirloom sword, using it without hesitation. Additionally, she demonstrates proficiency with tanks and artillery.
