One of the heirs to the Nishizumi school of armored warfare, Miho was once a student at Kuromorimine Girls' High School, and served as their Sensha-do team's executive officer under her older sister Maho, and her mother Shiho. Following an accident during a match in which Miho acted to save her personnel, which cost her school the victory, Miho transferred to Ooarai Girls' Academy in her second year. When Ooarai revived its Sensha-do team, Miho was chosen as the team's commanding officer, due to her tactical expertise and experience in armored warfare. (also, ignore the voice)
