Sachi Nagamiya

Sachi Nagamiya is a third-year student at Hinodemahama High School who shares a deep bond with Tōko Fukamizu. Due to her fragile constitution, she frequently finds herself in and out of the hospital, spending her quieter days immersed in books behind her signature glasses. Though generally soft-spoken and composed, she has no hesitation speaking her mind to those she holds dear. Her profound attachment to Tōko leads her to view the transfer student Kū Okikura—who suddenly grows close to Tōko—with unmistakable suspicion and hostility.
