Maho Nishizumi is the heiress to the Nishizumi family's Sensha-dō tradition. She is the older sister of Miho Nishizumi and daughter of Shiho Nishizumi. Physically, Maho has dark brown hair featuring two locks protruding from each side, dark brown eyes, and stands 163 cm tall. She typically wears Kuromorimine Girls' Academy uniforms or Sensha-dō gear, occasionally appearing in casual outfits like a striped button-up shirt with a blue dress or Ooarai uniforms during specific operations. Her background includes rigorous childhood training in Nishizumi-style Sensha-dō. During middle school, she won tournaments commanding a StuG III tank. A pivotal moment occurred when she fired upon an opposing flag tank during a rescue operation in a championship match, an action later criticized by Miho's friend Emi Nakasuga. When Shiho confronted her about the incident, Maho confirmed the tactical necessity according to family doctrine, straining her relationship with Miho. As overall commander of Kuromorimine's Sensha-dō team, Maho piloted a Tiger I tank with turret number 212. During the national championship match against Pravda, Miho's decision to abandon her tank to rescue teammates resulted in defeat, ending Kuromorimine's winning streak. Maho subsequently supported Miho's transfer to Ooarai to shield her from their mother's expectations. She discreetly monitored Miho's matches, loaned Kuromorimine's helicopter to Ooarai members for a family emergency, and defended Miho's tactics to Shiho during the Pravda match. Despite Shiho's order to defeat Ooarai in the finals, Maho acknowledged Miho's victory and commended her distinct Sensha-dō approach after their tank duel. In *Der Film*, Maho led Kuromorimine reinforcements transferring to Ooarai during the match against the All-Stars University Team. She commanded the assault on the central hill, directed defenses at the amusement park's southern entrance, and eliminated diversionary units. Her tank survived the entire 30 vs. 30 battle, and she coordinated closely with Miho to defeat the All-Stars command, providing tactical guidance and emotional support throughout the operation. Following Kuromorimine's loss to Ooarai, Maho reformed her school's Sensha-dō team with new tactics and cultural initiatives like the Post-Training-Non-Alcoholic Beer Festival. She later departed for Germany to study at Niedersächsische Universität on a tank scholarship, transferring command to Erika Itsumi. During her studies, she participated in Darjeeling's Tankathlon Tournament under the alias "Team Nishizumi Mask," defeating Tategoto High School in a 5 vs. 1 match using a Panzer II tank. Personality-wise, Maho projects a stern demeanor to meet familial obligations but privately demonstrates kindness and concern. She organized a Christmas party for Kuromorimine students unable to return home, though her communication style caused unease. Her primary motivation is protecting Miho's freedom from the Nishizumi legacy, summarized as: "As long as I'm the inheritor of the Nishizumi school, Miho will be free." She possesses heightened situational awareness from Nishizumi-style training, enabling her to detect hidden threats like ambushes. Trivia notes include her birthday on July 1st (coinciding with the First Battle of El Alamein), her favorite tank (Panther Ausf. F), her favorite flower (sakura), and ownership of an Akita dog. She shares a familial sensory ability to detect incoming projectiles or approaching tanks without visual confirmation.
