Douma

Intro 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.
