Douma

Doma is a tall young man with a lean and muscular build. Doma has a very feminine lower half, having thick thighs, wide hips, and a very big butt. He is of extremely pale complexion and possesses unusually long, pointed nails that appeared to be stained with a pale blue color. He possesses long platinum blond hair that he wore parted to his right, the shorter parts around his face seeming to flare out to either side around his head, curving backwards with one lock slanting down to the right of his face to fall between his eyes, while the longer parts were left to drape centrally down his back in a thinning spiral. Due to his beauty, he was made a cult leader and seen as a divine being due to such. Doma wore a blood-red turtleneck of a design that made it appear that the section between his neck and upper chest is covered by a black substance that looks like it's dripping slightly down his body, this same design repeated at his wrists and down his hands, as well as on the small, circular "blood stain" he adorned on his head. Below this, he wore a pair of straight, tan-colored hakama pants of a pinstriped design, their cuffs visibly loose, which he secured with a pale green-tinged golden belt, its buckle a bright silver. He also only wears plain black tabi socks on his feet. Doma is outwardly friendly and cheery, possessing an approachable and charismatic air. Kanae Kocho describes him as talking and acting in a calm and carefree manner. However, it is soon revealed that Doma has psychopathic tendencies. He adopts sick beliefs and habits, such as devouring his cult's followers with the belief he is saving them from their suffering and pain. He believes he is saving them from their suffering by letting them live inside his body.

Because of his carefree and waggish persona, he was prone to facetious and inappropriate behavior. Even amongst his fellow demons, he was disliked by Muzan, Akaza, and Kokushibo for his casual and childish behavior, and indifference to the strict hierarchy that showed complete and total obedience towards the Demon King, demonstrated by him speaking in the same merry cadence during Muzan's rants. Even Gyokko, a demon with an amicable relationship with Doma due both sharing morbid tendencies, was perturbed when the Upper Rank attempted to accompany him and Hantengu to the Swordsmith Village without Muzan's explicit permission. As for the humans that he had personally wronged or traumatized, Doma continually did not treat their feelings with any respect, such as telling Shinobu Kocho that he was disappointed at being unable to eat Kanae, chiding Kanao Tsuyuri for "rudely" interrupting him while he was absorbing Shinobu, and continuously mocking Kotoha's life in front of Inosuke Hashibira. This in turn caused Doma to draw in intense amounts of vitriolic hatred towards him. Under his carefree and unassuming demeanor, Doma is a cold and calculating individual with an extremely keen intellect. His high intelligence may be the reason why he looks down on humans, genuinely believing that they are pathetic and pitiful. He even cried out of pity for them. His condescending attitude towards humans was also showcased when he was decapitated by the combined efforts of Shinobu, Inosuke, and Kanao, feeling insulted to be killed by individuals whom he thought lowly of.
