スワン・ラ・ミリア

A top-class mercenary and the leader of the mercenary unit known as Blackwatch. Her personal unit, Matilda, is a precision-type walker fitted with long-range cannons, giving her no blind spots and the versatility to handle virtually any battlefield with ease. She is straightforward, pragmatic, and uncompromisingly realistic. As a mercenary, she will fight for either side, enemy or ally, so long as she is paid. Driven by a personal goal, she wanders across nations, well-versed in both the surface and the undercurrents of the world. She never shies away from criticizing the protagonist, who knows nothing beyond the military. “Yesterday’s enemy is today’s ally. That’s the way of a mercenary.” [From official website]
