Aoharu x Machinegun

青春×機関銃

Hotaru Tachibana, a girl who passes as a boy and can't ignore injustice, storms a host club to confront the host who swindled her friend. There she is challenged to a survival game by host Masamune Matsuoka, where the first person hit by a toy-gun pellet loses. After Hotaru loses and wrecks the club, Masamune drafts her onto his airsoft team, Toy Gun Gun, to work off the damages, never realizing she is a girl. Alongside teammate Tooru, an erotic-manga artist, she takes up the team's matches.
