Blight

Blight/Wisteria Demon

!!demon slayer spoilers!!

any pronouns for now idk what their gender will be

They are almost always referred to as The Wisteria Demon. When Muzan tried to make tanjiro the next head of the demons, he was initially successful. He killed all of the demon slayers left alive, along with nezuko. However tanjiro‘s body eventually retaliated, and before tanjiro died the body split into 4 parts. The Wisteria demon, the  Blade Demon, the Sun Demon, and an unknown 4th demon. Each became the 4 most powerful demons. 

Blight is the weakest of the four, being immune to the effects of wisteria. Their blood demon art has allowed them to create a disease which either kills humans or slowly turns them into demon. The already small demon slayer core has their main focus on Blight, as the other 3 have not shown themselves in a long while.

Blight was the one who turned Micheal into a demon. Micheals main goal is to kill him. Blight tolerates Strelitzia the most, having recived the most blood of any demon they’ve created.

Their personality/vibe is very creepy and sinister. Face is usually expressionless unless they are tormenting others, which they find amusement in.
