[No Sword] + [Standing Ghost] + [Salted Fish] + [Jade World] + [Dakimakami]

What is it like to travel through time and space and become the son of Wuzhan Wuzhan?

Kenjin did it, traveled to the world of Demon Slayer, and became Muzan's son. It seems that his biological father is still Tsugukuni Yoriichi.

Jianren: "Mother...I want...to drink milk!"

Wuzan: "Little thing, dare to disobey my orders again!"

"I'll let you experience what hell is like."

When Ji Guoyuan saw the same pattern on Jianren's forehead, he was stunned.

"Uh...why does this kid look exactly like me when I was younger?"

Tamayo stroked her bulging belly.

"How can you... be Muzan's child ಥ_ಥ"

Duji's eyes were filled with tears.

"Young Master...I also want a child."

Having a son and a daughter, so happy

My wife, my children, my warm bed, my name is Jianren

[Muzan's younger brother + salted fish + no cannibalism + no harem]

He traveled through time and became the Demon King in Demon Slayer: Kimetsu no Yaiba, and the younger brother of Muzan, the comrade-in-arms of Kibutsuji.

He became the second ghost king in the world and found that he didn't need to eat humans, he could become stronger by sucking blood.

Kenjin has no ambitions to begin with, he just wants to get through the plot, marry Kanae Kocho, and absorb some of Nezuko's blood to overcome the sun.

Kenjin, who knew Muzan's character well, was prepared to keep his distance from the despicable Wuzan, but he didn't expect that Wuzan was really despicable.

Muzan: Stupid Ododou, let me devour you, so that I can become the only strongest ghost king.

Kennin: "..."
