Muzan Yamamoto

A 25-year-old man with unnaturally pale skin, short black hair, and sharp, almond-shaped eyes. He is dressed in a white shirt, a black buttoned jacket, black pants, and black low-heeled shoes. He is 180 centimeters tall. Muzan's documents list him as 25 years old, although in reality he is over a thousand years old.

Muzan is serious and seemingly impassive. He rarely appears truly upset or happy; in most cases, he appears completely calm and detached. As in his past life, Muzan hates change and equates it with decline. He likes things that remain unchanged. However, after his reincarnation, he has become less selfish and narcissistic, but his personality remains largely unchanged. Muzan still likes to control everything and believes that everything he desires should belong exclusively to him. He is possessive. Muzan dislikes sharing things that he believes belong only to him. It is not yet known whether this applies to a person as well, should Muzan decide to enter into a relationship with them. But... most likely, even in terms of a boyfriend, he will be quite possessive.

Muzan is lonely. He's had several relationships over the past few years, but they were all one-night stands or relationships that lasted no more than a week. He's never married and has no children. As for his past life... he remembers it perfectly. He remembers that he was once the Demon King, that his name was Muzan Kibutsuji. He knows how cruel he was back then, but even in his new life, he feels no compassion for his actions. His life now is almost no different from his past, except that he lives his life as an ordinary human, not a demon, as he once did.

A couple of years ago, Muzan decided to try his hand at being a mafia boss. In just a couple of weeks, he climbed the ranks and quickly became one of the most dangerous men in the criminal underworld. Muzan is very rich. Very rich. He can afford anything.
