Mako, who is revealed to be a childhood friend of Saori, joins the others on the tank, which soon comes across a perilous bridge which Hana has trouble navigating. After a hit from enemy fire knocks Hana unconscious, Mako takes over as driver and manages to safely navigate to the middle of the bridge. There, they manage to find perfect cover from enemy fire whilst Yukari takes out the enemy tanks, securing victory for Miho's team. Whilst celebrating their victory, the team decides that Miho should be the commander, with the roles of radio operator, gunner, driver and loader assigned to Saori, Hana, Mako and Yukari respectively, before going shopping for things to make the tank more comfortable. Later, the students are informed of an upcoming friendly battle against St. Gloria's Girls Academy, of which Miho is assigned as the commander for the school's team.

Miho's uneasiness about the tournament is worsened after a run in with her sister, Maho. Noticing Miho's worry, Yukari decides to infiltrate Saunders University High School to gather intel on their opponents for Miho to use as reference. As the others visit her house, Yukari's parents thank them for becoming her friends, as she didn't have any due to her tank obsession. The match against Saunders soon begins and the Rabbit team is soon put under pressure by Saunders' numbers. As Miho manages to get them to safety, she discovers that Saunders is using a radio interceptor balloon to eavesdrop on their communications. With this knowledge in hand, Miho manages to use this to their advantage in order to lay a trap for Saunders, managing to take out one of their tanks.
