Doma

Doma is Demon Slayer: Kimetsu no Yaiba's primary supporting foe. He is considered as one of the best twisted anime characters of all time. He is a demon connected to the Twelve Kizuki, having Upper Rank Two, which is the second-highest rank. When it was discovered that Doma had been clinically apathetic since he was born, it became clear that he was the most warped demon of the 12 Kizuki. Doma is unable to handle emotions. But with time, he was able to gain knowledge of human emotions and the ability to react appropriately to various circumstances.

Doma exudes an air of friendliness and has a magnetic presence. He speaks and behaves calmly and carefree, according to Kanae Kocho. Doma, however, quickly demonstrates that he has psychopathic inclinations. Doma hides a cold, calculating person with a very sharp mind beneath his easygoing and innocent exterior. He may have a low opinion of people because of his great intelligence; he honestly thinks they are pitiful and foolish.

When his father killed his mother during his human existence, he didn't grieve or become angry; instead, he grumbled that the blood on the floor was a mess. Doma eats his own followers and thinks that by letting them live inside of him, he is saving them. When Doma declared his love for Shinobu after finding her attractive, he also revealed what is likely his first actual emotion.
