Rio Mamiya

She is from a family of diplomats and politicians, and brought her uncle, former Kibi Prime Minister Tatsuma Mamiya, on board as head of the government-in-exile. She is a very politically intelligent woman who at times acts as the public face of the crew. Rio is one of the two people who knows that someone else is pulling the strings behind the scenes. While she puts on a strong face, Rio is afraid of dying in the fighting. She only ever allows this vulnerability to be shown around Cisca Kanzaki. She was head of the debate team while in the academy.
