An apocalyptic event has ravaged Japan, leaving nothing but endless sandy plains behind, and a strange rusting disease terrorizes the remnants of civilization. According to the government, the horrific state of the new world is the result of mushroom spores being spread by the likes of Bisco Akaboshi, labeled the "Man-Eating Mushroom." But Bisco would beg to differ. In reality, he is a "Mushroom Protector," determined to uncover the legendary "Sabikui" mushroom—said to be the ultimate cure for the rusting disease. Joining him on his quest are his giant crab Akutagawa and the kind doctor Milo Nekoyanagi, who is actively searching for a rust poisoning treatment for his sick sister.

Rifle-shooting sports are competitive activities testing accuracy and precision using a rifle. In Japan, carrying firearms is prohibited, so most of the participants are members of the defense force. When the use of rifles using a light beam instead of real bullets as ammunition became common, rifle-shooting competitions became accessible to the younger population, giving way to school contests. First-year high school student and marksmanship enthusiast Hikari Kokura has just transferred to Chidori High School. She tries to join the club of her choice, but finds out that the club no longer exists due to the low popularity of the sport. Distraught, she tries 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, who have only one goal—to compete on the national stage!
