The daughter of Shiho Nishizumi and older sister of Miho Nishizumi, Maho is a third year student at Kuromorimine Girls Academy, the overall commander of her school's Sensha-dō team and also the heiress to the Nishizumi family. She is the commander of a German Tiger I. Maho is well known for her strong passion of Sensha-dō, being a talented skilled leader and well-respected by many including her teammates. She seems cold and distant toward others at times, but this is actually a facade in order to fulfill her mother's strict expectations. In reality, she's a very kind person, even to her opponents, and loves Miho dearly. The reason she strives to be a good Nishizumi heiress is so that her younger sister Miho will be free to live her life as she wishes.
