The airsoft matches stop mattering the second Yuki's cosplay costumes hit the field. The show trades tactical precision for pure comedic chaos, and somehow that makes the survival game actually feel alive. Twenty minutes of gorgeous animation wasted on characters too busy looking incredible to remember they're supposed to be winning.

Team Gun Guin enters a new survival game and is caught off guard to learn that everyone has to compete in full cosplay. Yuki supplies the costumes, and the match becomes a string of hijinks as the team works out how to beat its opponents. This action comedy OVA is the unaired thirteenth episode of Aoharu x Kikanjuu, released with the sixth BD/DVD volume.
