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! [Written by MAL Rewrite]

A Keio University (one of the top three colleges in Japan) exam candidate, Touma Inaba, is interupted when a cute young girl, Urara Kasuga, arrives at his hotel room door. She later turns out to be his cousin who he barely remembers from his childhood. Urara, who had felt something special for him (an other-than-cousinly-love), invites Touma to live with her since he has no place to stay other than the hotel room. Before taking the test, Touma meets Meiko Yotsuba, a beautiful, sophisticated woman also trying to get into Keio. Meiko gets into Keio but Touma does not, due to a cold Urara had given him shortly before. Although he did not make it, he pretends he does to earn the respect of Meiko. Touma is caught up in a love triangle with Urara and Meiko, while struggling to keep Meiko believing he's really a Keio student and still be there for Urara at the same time. (Source: ANN)
