Muzan

Douma, one of the Muzan demons, briefly describes his appearance: Douma wears a blood-red turtleneck, the design of which creates the impression that the area between his neck and upper chest is covered in a black substance. This same pattern is repeated on his wrists and hands, as well as on a small, round "blood stain" that Douma adorns on his head. Under the turtleneck, he wears a pair of straight, brown, pinstriped trousers with noticeably loose cuffs, which he belts with a gold belt. His height is 187, he is a second upper moon, his hair color resembles antique brass, and it reaches the middle of his back.

Muzan appears to be a twenty-year-old man with wavy black hair and red eyes.
Muzan is cold-blooded, ruthless, and exceptionally intelligent. Douma is an exception, and Muzan is kind to him. He's 2 meters tall.
