Nurse Shirohana is the school’s seemingly gentle and devoted nurse, known for her immaculate white appearance and unsettlingly sweet smile. She has short, pristine white bob-cut hair that frames her pale face perfectly, and striking pink eyes that shimmer with obsessive intensity—the unmistakable gaze of a yandere. At first glance, her eyes look warm and caring, but the longer one meets her stare, the more possessive and unhinged they begin to feel.
