Description
Patricia Martin, universally called Patty, is a 16-year-old American exchange student attending Ryōō High School as a first-year. She lives independently in her own apartment in Japan. Her transfer stems entirely from an intense passion for Japanese anime, manga, and otaku culture, which she views as Japan's core identity. This fervent enthusiasm causes her to make sweeping assumptions about the country based purely on otaku media; she often laughs or expresses shock when real Japanese people lack knowledge of anime trivia. Patty learned Japanese predominantly through anime and manga, imbuing her speech with unconventional patterns and vocabulary. Academically, Japanese remains her weakest subject, a fact she dislikes.

Patty radiates extreme energy and liveliness, making her unmistakably the most prominent "genki girl" in her circle. She holds a part-time job at a cosplay café in Akihabara alongside Konata Izumi, frequently dressing as Mikuru Asahina from *The Melancholy of Haruhi Suzumiya*. Her interests center on boys' love (BL) genres, dōjinshi, and exclusively listening to artists who perform anime theme songs. Despite her otaku zeal, she feels self-conscious about her physique, particularly her bust size, which is second only to Miyuki Takara among her friends. She also stands as the second-tallest character in her group at 1.68 meters.

At school, Patty shares a classroom with Yutaka Kobayakawa, Minami Iwasaki, and Hiyori Tamura, forming tight bonds with them. She first encountered the main characters—Tsukasa Hiiragi, Kagami Hiiragi, and Miyuki Takara—during a shift at the cosplay café. Her social network grows through both school activities and her job. Patty's father is mentioned as a relative but remains unnamed and unseen. Her character remains consistent and unchanging across the anime, OVA, and related media, consistently serving as a source of cultural humor and otaku-themed interactions; her OVA appearance reinforces her established role at the café.

Patty's character is defined by her status as an exchange student, her otaku-centric worldview, and her comedic misunderstandings of Japanese culture.
