Aoharu x Kikanjuu: Kemono-tachi no Senjou da na!

Hotaru Tachibana, Masamune Matsuoka, and Toru Yukimura enter Toy Gun Gun in a new airsoft tournament with an unusual requirement: every participant must compete in costume. Preparing for battle suddenly involves a challenge none of them normally faces on the field.

Hoshishiro is drawn into the same spectacle, bringing familiar competitive intensity to the unlikely setting. Serious players and unconventional outfits collide as the tournament turns into a lively confrontation where appearances offer little guidance about what will happen next.
