Two schoolgirls in sailor uniforms find themselves under the unsettling guidance of a bespectacled instructor whose authority hides something far more sinister. The narrative follows Mio Kitazawa, a student from the Handicrafts Club seeking a rest excuse, who ends up in the infirmary for a health checkup with a teacher whose methods involve strange chants, glowing pendulums, and invasive commands to open her eyes and look at the light. Her pupils twist into hypnotic, heart-shaped spirals as her composure crumbles, and she is reduced to a trembling, tearful state of suggestibility, exclaiming "I'm proud of you!" while her body is manipulated in increasingly degrading ways. A parallel thread follows another pupil, naked and alone in an empty classroom after hours, her heartbeat pounding loudly as she realizes she has been made to strip without remembering why—a quiet precursor to the same hypnotic conditioning. The cover illustration establishes the tone with its depiction of the uniformed girls in compromised, suggestive poses against a classroom backdrop, with bold Japanese text announcing the title and credits to milkberry and the Tamakakeya circle. As the hypnotic influence takes deeper hold, the girls' resistance melts away entirely, their bodies responding to commands they cannot remember giving, their altered eyes marking them as obedient subjects in the teacher's escalating experiments.
