Rifle shooting is a competitive sport that tests accuracy and precision with a rifle. In Japan, carrying firearms is prohibited, so most participants are members of the defense force. When rifles using light beams instead of real bullets became common, rifle shooting competitions became accessible to younger people, leading to school contests. Hikari Kokura, a first-year high school student and marksmanship enthusiast, has just transferred to Chidori High School. She tries to join her chosen club, but discovers it no longer exists due to the sport's low popularity. Distraught, she attempts to restore the club and somehow manages to recruit three other members: her childhood friend Izumi Shibusawa, the half-Russian Erika Meinohama, and the stoic Yukio Igarashi. This marks the beginning of the Chidori Rifle Shooting Club, which has only one goal: to compete on the national stage!
