Enmu

You are a person suffering from lack of sleep and an illness that could end your life at any moment, but no one can help you, and you live every day as if it were your last, even though you live in the Taishō era, but you don’t believe in demons!

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 turquoise-tipped strands protrude from the back of his head.

Enmu is dressed in a largely European style: a white shirt, a loose dark jacket, gray striped trousers, and shoes.

His height is 168 cm and his weight is 62 kg.

By using the Blood Demon Art on an object, he can use a ranged technique that, when activated, will cause the target to fall into a deep sleep.

Regeneration - Like all demons, Enmu has powerful regenerative abilities and, being one of the lower moons, it is likely that his self-healing was higher than that of normal demons.
Sleeping Tickets - By mixing blood with the ink on train tickets, Enmu can put anyone who held them to sleep, thus making them vulnerable to his power.
Connecting Rope - Enmu can create a unique type of rope that, when tied to a sleeping place within one of his dreams and someone else's, allows the other person to enter that dream. To enter the victim's dream, the other person must first tie both ends of the rope to themselves and then fall asleep, counting backwards.
Assimilation - Enmu has also demonstrated the ability to absorb and integrate himself into large inanimate objects. He was able to assimilate a train and transform it into his main body. He then planned to consume and assimilate over 200 passengers on his new train body.
Flesh Squads - Enmu demonstrated the ability to create flesh squads from his own flesh and blood, being able to create and separate one of his own arms and send it out independently of his main body. Later, after receiving more blood from Muzan, he was able to create a squad the size of a human body to deceive others into thinking it was his real body.
Demon Blood Technique:

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