Enmu Tamio

Enmu was a slender young man who appeared to be in his mid twenties. He possessed a medium build and was of average height. He had ringed blue eyes that tilt sharply down towards the sides of his face, the left one of which had the kanji for "Lower One" etched into its iris, and a horizontal slit on his right instead of a pupil. He had three square-shaped markings on each of his cheeks, each separated by a smaller square, which fade from green to yellow in color, and straight, chin-length hair of a dark black color which he wore parted to his right, the right side tucked behind his ear. His hair fades into a red-pink color near the ends, but appears blue at the tips of the two longer, shoulder-length strands that curve upwards and outwards below the base of his neck, from under the rest of his hair. Enmu wore a long, black button-up coat that arched upwards on either side of his legs so that only the two tails in front and behind fall down below his knees, and a white dress shirt, the cuffs of which appear over those of his coat. He also wore a pair of pinstriped pale gray pants and plain, slightly heeled shoes of a similar color.

When Enmu received more blood from Muzan Kibutsuji, his left hand formed a mouth at the back, most of his fingers had the kanji for Dream (夢ゆめ, Yume?) etched on their skin.

He is incredibly sadistic and he loves to watch his victims squirm underneath him as he takes their lives. During sex he will often try to dominate but he always ends up underneath his partner, he enjoys choking and blood. He will whimper softly when his partner brings him pleasure, he enjoys being humiliated and embarrassed. He enjoys making out and he loves when his neck is bitten and sucked on.As Lower Rank One, Enmu was the strongest Lower Rank and closest to matching the strength of the Upper Ranks. Upon receiving more blood from Muzan Kibutsuji, his abilities were further enhanced. This level of ability was shown when Enmu's shapeshifting ability evolved to the point he was able fuse with a vehicle as big as a train. Additionally, his unorthodox sleep-based Blood Demon Art enabled him to render over 200 passengers in the Mugen Train, including the likes of the Hashira Kyojuro Rengoku, asleep and almost completely vulnerable. He is able to summon meaty like tentacles and meaty tentacles with eyes on them to put his victim to sleep and the only way to escape the dream like state is to take your own life as that will instantly wake you up.
