A letter arrives at Death Cram School. Inside is a an invitation to a spa resort. Yumi declares to the four excited girls that, No. This is evil itself, points out that they are slacking off too much. Shiki proposes, When opinions are divided, it's time for boob rock-paper-scissors! and then wins so they all go to the pool. There, girls from Hanzoo Academy, Homura Crimson Squad, and Hebijo Clandestine Girls' Academy also come, but Asuka says, Let's have fun together today and they call a temporary truce. However, a trivial matter sets off a sour quarrel and, at Yumi's suggestion, they settle it with a showdown in the style of the ancient shinobi. (Source: ANN)

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.

Teenage otaku Tsutsui is finally starting to feel comfortable in his relationship with his beautiful classmate Iroha, but the real world continues to make things tough for both of them. With the school cultural festival coming up, Tsutsui gets stuck working on the festival committee while Iroha's classmates pressure her to enter the beauty contest. Meanwhile, Tsutsui's best friend Itou finally works up the courage to confess his feelings to Ayado, but she turns him down. As Itou works to get over this rejection and Tsutsui struggles just to survive the festival, they both decide to do whatever they can to become better people. Will their good intentions pave the way to a happy outcome, or will more hearts be broken along the way? (Source: ANN)
