Jun Takahashi, a diligent high school class representative sharing courses with Koizumi, Yuu Osawa, and Misa Nakamura, possesses long green hair and signature purple glasses. These glasses initially led her to avoid steaming ramen to prevent fogged lenses and resulting embarrassment. She resides as an only child with her mother, an editor at a publishing company. This literary environment fuels Jun’s aspirations while amplifying her anxiety about future careers; she doubts her capacity to become a novelist or join her mother’s firm despite academic dedication.

Peers view Jun as orderly and reliable, frequently spotting her studying in the library or reading during breaks. Classmates estimate she consumes roughly one hundred novels per school vacation. Underneath this composed exterior, she grapples with intense nervousness during stressful scenarios, including interactions with Koizumi’s eccentric behavior. High-pressure situations like weekend cram school mock exams can suppress her appetite for a full day. She aims to place within the top 50 on national mock exams and has visited a shrine to petition for this outcome.

Koizumi’s influence gradually reshapes Jun’s stance on ramen. After complete avoidance to dodge glasses fogging, Jun tentatively resumes enjoying ramen despite residual self-consciousness, marking broader growth in confronting discomfort through friendships. Within her social circle, she anchors discussions as a rational voice, leveraging her intellect for nuanced ramen debates with Koizumi. Though initially unsettled by Koizumi, Jun relaxes over time, sharing career anxieties while noting Koizumi’s carefree outlook.
