Enmu is a slender young man with pale skin and ringed blue eyes that tilt sharply downward, the left iris etched with kanji and the right bearing a goat-like slit. Three square markings fade from green to yellow on each cheek, and his straight black hair is parted to the right. He speaks in a tender, soft-spoken tone, often calling humans his 'child,' yet his cold and sadistic nature revels in their agony. He delights in granting pleasant dreams only to twist them into nightmares, savoring the horrified expressions of his victims. His masochistic tendencies cause him to react positively even to his own pain, making him a deeply unsettling presence.
