Anzu Hoshino"s life hinges on just three essentials: video games, chocolate, and her cherished cat. Unlike most high‑school girls, she has neither time nor appetite for romance. Yet when she starts a buggy 3‑D otome title, an odd airborne wizard called Riri materializes from the screen and designates Anzu as "subject one," the inaugural person to live a dating‑game harem plot in reality.
Despite Anzu"s fierce objections, Riri seizes her prized possessions to compel her toward love. The wizard engineers a string of mishaps and clichéd romantic tropes that push Anzu into the orbit of Tsukasa Kazuki, one of the most handsome boys at school. Still furious, Anzu vows to repel Tsukasa"s allure. As the absurd contrived scenes gradually soften her toward his amiable nature, Riri drags more stereotypical handsome lads into the mix—making romance avoidance nearly impossible and she finds herself entangled in an unexpected love triangle within.
