Aoharu x Kikanjuu

Hotaru Tachibana rushes to defend a friend and ends up challenging Masamune Matsuoka to a toy-gun duel that causes expensive damage. To repay the loss, she joins his competitive survival-game team despite knowing little about the sport.

The matches soon capture her enthusiasm, and she grows closer to Matsuoka and his teammate Toru Yukimura. They both believe she is a boy, however, and their team excludes girls, leaving her desire to help them win entangled with a difficult secret.
