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]

For Hikari Tsutsui, life within the two-dimensional realm is much simpler. Socially inept and awkward, he immerses himself in video games and anime, only to be relentlessly ridiculed and ostracized by his classmates. Sharing his misery is Yuuto Itou, his only friend, who wears cat ears and is equally obsessed with the world of games. After being forced to clean the pool as punishment for arriving late, Tsutsui meets Iroha Igarashi, but he attempts to steer clear of her, as her notoriety precedes her. Brazenly blunt, loathed by female classmates, and infamous for messing around with boys, Tsutsui believes that getting involved with her would cause nothing but problems. 3D Kanojo: Real Girl is a story revolving around these two outcasts—a boy full of emotions he has never experienced before, struggling to lay them bare, and a girl who strives to break him out of his shell.
