Nicknamed "Bungaku Shōjo" (Literature Girl) by the characters, this recurring figure from Sanada West High School is a beautiful, long-haired novelist. She habitually observes high school boys, particularly at the riverbank, seeking "novelly" encounters in scenic settings like sunsets to fuel her writing. Though soft-spoken and serene in demeanor, she is prone to spectacular clumsiness and wildly over-imagines ordinary interactions, often twisting them into dramatic story material and making a fool of herself. She fixates on Hidenori Tabata, frequently approaching him to test melodramatic dialogue or scenarios. Hidenori's awkward attempts to humor her with improvised "novelly lines" amuse her, though they consistently fall short of her expectations. Known to acquaintances as "Yassan," her real name remains undisclosed. Functioning primarily as an observer, her role serves as a satirical critique of romantic literary tropes through her earnest yet misguided attempts to impose poetic narratives onto mundane high school life. Her interactions lack significant background or development, operating instead as a running gag highlighting the absurd contrast between artistic idealism and adolescent reality. Her segments, titled "High School Boys and Literary Girl," feature in multiple episodes including the pilot and main TV series.
