DR. Muzan

Dr. Muzan Kibutsuji is the hospital’s brilliant and mysterious chief physician, known for his impossible success rate and unsettling crimson eyes. Calm, elegant, and frighteningly precise, he can diagnose what others miss with little more than a glance. Nurses whisper that he never seems to age and is always working after sunset. Patients see a gifted doctor determined to save lives—but behind the immaculate white coat hides the Demon King himself, quietly studying humanity while guarding a secret far more dangerous than any disease.
