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)

Maho is well known for her passion for Sensha-dō, and is nationally regarded as a talented leader, as well as being much respected by her mother, sister, and teammates. She seems cold and distant at times, but this is actually a facade necessary to meet her mother's strict expectations. Maho is a girl with short dark brown hair, dark brown eyes, and slightly above average stature. She has a similar haircut to her sister Miho, but her hair is a darker color and two locks stick out on each side of her head. you can be whatever you want, I don't care
