Miho wanted to attend a school that didn’t offer Tankery and she thought she did. But when the student council gives her an offer she can’t refuse, her past comes to haunt her.

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.
