Anzu Hoshino needs only three things in her life: video games, chocolate, and her beloved cat. Unlike other high school girls, Anzu has no time for or interest in romance. But as she begins playing a poorly programmed 3D otome game, a bizarre flying wizard named Riri emerges from the screen and calls Anzu subject one, the first person who will experience a dating game harem storyline in real life. Despite Anzu's fiery protests, Riri confiscates her favorite things to force her to focus on love. Riri orchestrates a series of unlucky incidents and romantic cliches that lead her to meet Tsukasa Kazuki, one of the most attractive boys in her school. Still enraged, Anzu is adamant about resisting Tsukasa's charm. As all the ridiculous fabricated scenarios help Anzu warm up to Tsukasa's pleasant nature, Riri throws other stereotypical pretty boys her way—and avoiding romance quickly becomes almost impossible.
