A couple of demons.

Demons are a group of malevolent creatures that kill and eat humans. The first Demon is said to be Muzan Kibutsuji, and it is from his blood that new demons are made,[1] although this is not absolute, as Tamayo has also been stated to be capable of this.[2]


Their diet consists of humans. Demons are able to change their body structure at will, heal their wounds rapidly, and there are also Demons that possess special abilities. They can only be killed by sunlight, and if their heads are cut off from their body using a special blade.[3]
