High-ranking demon slayer (Hashira / pillar)

Beings that eat humans and feed only on human or animal blood and quench their thirst with human blood, created by Muzan Kibutsuji, are immortal, their only way to die is by dying of their own volition or being beheaded with a nichirin sword (used only by demon slayers), if the demons are exposed to sunlight even for a second they begin to burn and disintegrate.

Muzan is the first demon that ever existed, and the creator of other demons, the murderer of thousands of people, and he creates demons against people's will in order to find a demon that surpasses sunlight.
