[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: "..."
