The post-movie cool-down lap where Ooarai gets to just be themselves again, without the entire school hanging on their shoulders. After 75 minutes of feature-film intensity saving the academy from the wreckers, this OVA lets you breathe with these girls and their tanks without the weight of institutional collapse pressing down. It's the victory lap that proves what made the whole franchise work: watching a team that genuinely likes each other figure out impossible problems together.

Arisu War! is a short comedy special set after the events of Girls und Panzer der Film. It came bundled with the film's Blu-ray and DVD release, alongside more of Yukari's tank lecture segments, where she explains the armored vehicles of the franchise. Viewers should see the film first, since the special picks up after its story.
