“I must say, I like to show a nightmare after I show someone a good dream. I love to see the contortions of a human face! To gaze upon someone struggling with grief and suffering is so much fun!”

Enmu could not distinguish between reality and a dream at a young age. When he became an adult, he started healing people. He was not a doctor, and he did not have any knowledge of medicine. He uses hypnosis to make the patients believe that they are already cured. Later, patients would discover that they were scammed. Despite this, Enmu would continue doing the same.
One night, Muzan came to his house to devour him. Muzan started eating his guts, and to Muzan’s surprise, Enmu did not feel anything at all; he did not feel any pain. He even praised Muzan with his last dying breath and this impressed Muzan. Muzan then decided to make Enmu one of his demons.
In the last episode of the first season, before the event of Mugen Train Arc transpired, when Muzan was killing all the Lower Moons because of his disappointment, he asked Enmu his last words. Enmu, instead of saying his regrets or sadness, thanks Muzan.
He thanked him for all that he had done for him for the past years. He even praised Muzan for all the suffering that Muzan was able to cause. Hearing him say that, Muzan decided to give Enmu another chance.
Muzan gave Enmu more blood so he could become stronger. The blood Muzan gave Enmu was too much that Enmu almost died from it. He felt so much strength and power from the blood he received that his body could hardly process it and almost exploded.
Enmu then attacked a train and used it for hunting for bodies and eating them to make him stronger. He manipulated the train conductor he attacked and used his demons to attack the passengers.
His demon disciples are given ropes that they will use to connect to the dream of the person they are tied with. The demon disciples are supposed to destroy the core of the demon slayers. This plan failed horribly.
Enmu did not have intel on Nezuko, hiding inside the box. He also did not consider what the dreams of the demon slayers would look like and that they might be fighting someone in their dreams.
While the passengers, including the members of the Demon Slayer Corps, are sleeping, Enmu is infusing his body with the train. When he finally becomes part of the train, the demon slayers start to wake up and fight back.
Seeing that his little disciples had failed, Enmu was enraged. Inosuke and Tanjiro attack the head of Enmu, which is carefully hidden in the engine room. When using his eyes to hypnotize Tanjiro and Inosuke, he failed as Inosuke wore a mask that shielded his eyes from his hypnotic attack. In the end, Enmu died.
Enmu has ringed blue eyes that tilt sharply down towards the side of his face. His left eye has the kanji for “Lower One” on its iris. His right eye does not have an iris but a horizontal slit instead. Enmu has an average height, is pale-skinned, and with three square marking on each side of his cheeks.
These markings are separated by smaller squares that fade from green to yellow. He has straight chin-length hair. This hair is parted in half, with the right side tucked behind his ear. His hair fades into a red-orange color.
He wears a button-up coat arched upwards on either side of his legs. The two tails in front and behind fall down below his knees. He also wears a white dress shirt and cuffs, which appear over his coat.
He also wears pants that are pinstriped and shoes that have the same color. After receiving blood from Muzan, his left-hand forms a mouth at the back, with an eye next to it. On every finger of Enmu is also etched the kanji for dreams.
Enmu does not care for the lives of any human being. He is sadistic, loves seeing human beings suffer, and torments them. His favorite type of torment is giving humans beautiful dreams only to give them nightmares afterward.
When other members of the lower ranks were killed one by one by Muzan, he was secretly relishing the moment. For Enmu, the weak are mere pawns, whether humans or demons.
Enmu has a high intellect. He knows the strength and weaknesses of his power, and he knows perfectly well how to utilize them. Having received more blood from Muzan makes him arrogant and greedy, and he forgets how to play well using his power. Enmu is no easy opponent as he is good at exploiting the weakness of a human heart.
Enmu can infuse in any object he chooses since Muzan gave him more blood. He can infuse his body with a train. His ability to put people to sleep and make them dream while eating them had also been better.
He is ranked first among the Lower Moon, so it is best to assume he has the closest power to the Upper Moon. The speed and reflexes of Enmu are also extraordinary. He was able to dodge attacks from two demon slayers who were attacking him at the same time.
The flesh manipulation of Enmu is extraordinary. Aside from attaching his body to the train, he can also use his flesh to eat the passengers slowly.
These parts of him also serve as his eye on other parts of the train. He can simultaneously attack demon slayers who are indifferent cars of the train. All these attacks are possible since he can induce sleep in his victims and manipulate their dreams.
