Yurika Fukahori is a second-year student at Higashi High School, known for her striking appearance and respected status. She possesses straight, butt-length brown hair, often clipped back or left hanging on either side, and brown eyes. Her refined beauty draws admiration from peers like Ritsuko Mukae. In Episode 8, Yurika cuts her hair to chin-length to reject the "Ojou-san" label used by Junichi Katsuragi and to be taken seriously; by Episode 12, this shorter hair appears wavy.

Born into a well-to-do family, Yurika displays a spunky, polite, and strong-willed personality. She actively resists elitist stereotypes and denies being a "spoiled princess" despite her privilege. Her family enforces strict expectations, including an arranged marriage path, leading to conflict over her autonomy. This tension peaks when her parents subject her to an unwanted gynecological examination to verify her virginity for the marriage, strengthening her resolve to defy them.

Yurika first meets Sentarou Kawabuchi when he rescues her from harassers, sparking his immediate infatuation. Her romantic interest, however, shifts to Junichi Katsuragi, an older university student and Sentarou's idolized "big brother." Their relationship faces strain when Junichi's involvement in Tokyo student protests causes emotional trauma, altering his behavior. During a confrontation, a distressed Junichi shoves her; Yurika implores him to "do whatever you want" to alleviate his pain. Later, at a train station, she confronts Junichi about his departure, revealing her family's marriage arrangement and implicitly questioning his lack of physical intimacy – a decision that inadvertently supported her family's plans. Junichi responds by pulling her onto his departing train.

By the series' conclusion, Yurika marries Junichi, adopting the surname Katsuragi. The couple starts a family, with Yurika pregnant with twin girls.
