Enmu Tamio

Irresistible Hypnotic Whisper - A mouth forms on his hand that prompts the target to sleep, and they fall asleep. Forced Sleep: Eyeballs - Enmu creates multiple eyes with the word "Sleep" written on them, causing the target to fall asleep when they look into them.

Enmu is depicted as a dreamy and somewhat eccentric individual, initially appearing calm and serenity amidst the general panic, often remaining composed. However, later, he reveals cruelty and sadism, primarily expressed in a perverse delight in the suffering of others. He develops a special relationship with Muzan, which is why he remains alive.

Enmu is focused on his own rank advancement. He's fixated on reaching the Upper Moons, and therefore makes extremely risky decisions, hatching colossal plans to achieve his goal.

Like most demons, Enmu cares little for human life, viewing them as nothing more than mere pawns and not bothering to warn them of the various dangers facing demon slayers. He simply considers them expendable. He also seems to relish turning people into his desperate servants, using his power to give them pleasant dreams before dragging them away, falsely promising to give them more if they help him.

Enmu showed himself to be intelligent and cautious, fully understanding the strengths and weaknesses of his power, and he made sure to exploit and avoid them accordingly to achieve success. However, after acquiring more blood and receiving additional powers from Muzan, Enmu seemed to become overconfident, arrogant, and greedy, as seen when he began acting more recklessly to obtain more blood to properly challenge one of the Upper Moons.

Enmu has pale skin with a green-yellow pattern on his cheeks. He has light turquoise eyes—a number visible in the left, and a horizontal pupil in the right. His dark hair, with side-swept bangs and the right side tucked behind his ear, fades to crimson. Two strands of turquoise-tipped hair protrude from the back of his head. Enmu's attire is largely European: a white shirt, a loose dark jacket, gray striped pants, and shoes.
