When the Ministry of Education goes back on its promise to keep Ooarai Girls Academy open, the task of saving the five-mile-long Academy Ship from the wreckers falls to Miho and her barely-seasoned tankery team. However, things go off track almost immediately. While the Oorai tank crew may have won the high school tournament, they’re now facing a larger and more experienced university team, and if they fail, their armored vehicles will be forfeit! Will they be swapping their tanks for the memories? It’s possible, but winning a tank battle is all about tactics and teamwork, and the fledgling Ooarai students have more friends and allies than anyone suspects.

Too much tankery and not enough studying for her entrance exams has landed Momo in the hot seat! Luckily her friends won’t let her flunk out without a fight, and they’ve hatched a foxy plan to put her back on top. Miho’s stepping down to let Momo take up the mantle of commander, because if she can lead the team to victory in the Continuous Cup, Momo can retake her exams. The stakes have never been higher for the team as they fight for tank supremacy both on and off the combat field!

Following Oorai's victory over Saunders, the school's next opponent is Anzio. This is an OVA which covers the battle of Oorai versus Anzio, which was not fully shown in the regular anime series.

After falling for BC Freedom High’s clever deception, the Oarai Girl’s High tank-maidens find themselves faced with an entirely different battlefront than expected. However, Yukari suspects that any bluff that could have been carried out so easily by so many people must have some basis in fact. So, as the other school teams prepare for combat across the competition, Oarai digs down with a plan to undermine the groundwork beneath their opposition.

Firepower and strategy are the name of the game as the schools square off on three additional battlegrounds. Six teams enter and only the survivors will advance!
