A Grim Reaper in the School Nurse’s Office

At first glance, Hadesu Sensei seems woefully out of place in the sterile, quiet corridors of a middle school infirmary. With an unsettling pallor and an aura that borders on the spectral, he cuts a figure more suited to the underworld than a clinic for scraped knees and fevers. It is little wonder, then, that whispers ripple through the student body, branding him a shinigami—a grim reaper in human guise. His appearance, all sharp angles and shadowed eyes, hardly dispels the rumor, and his overly enthusiastic attempts at warmth and camaraderie often do more to unnerve his young charges than to reassure them. Yet beneath this disconcerting exterior lies a singular and invaluable talent. When a student falls prey to more than just a common cold, Hadesu Sensei reveals his true purpose: he is a master exorcist of *byouma*, insidious demons that manifest as illness and parasitically infest the bodies of the afflicted. While his colleagues treat symptoms, he confronts the malevolent source, drawing the dark spirits out with a proficiency that saves his students from invisible threats. For all his eerie demeanor and clumsy social graces, the school has found its most unconventional guardian—a being who treads the line between life and death to ensure the children in his care are never truly lost to the shadows of disease.
