Hokenshitsu no Otaku Onee-san wa Suki desu ka?

A new school nurse has arrived at Mitsugi Middle School, drawing attention from students who admire her appearance. To second-year student Tamotsu Kurita, however, she stands out for a different reason—her passion for 2D characters. Momoyama-sensei openly expresses her enthusiasm for fictional idols, with no interest in anything beyond them. While Kurita enjoys the chance to interact with someone attractive who shares his hobbies, he finds that her focus remains firmly on her favorite 2D characters. The story includes two additional chapters.
