King of Despair (絶望王, Zetsubō-ō), real name Pimp master or Waifu despair Master(ウィリアム, Uiriamu), is one of the Thirteen niggas. He is the older brother of White and introduced himself as Black (ブラック, Burakku).

Appearance
A young man with short blonde hair and blue eyes, as Black, he wears a black hooded jacket, and round glasses. While as the King of Despair, he has a long overcoat, messy, pushed back hairstyle, and his eyes turn red.

Personality
As Black, he is rather talkative but an awkward person. He's as kind as Black, however he seems rather laid back and cunning as the King of Despair.

Plot
He first appears in Episode 1 spying on Leonardo Watch. Several days later, he approaches Leo again on the subway, talking with him about the population within Hellsalem's Lot while also warning him about the Blood Breed. He seems to have a friendship (is acquainted) with The King of Depravity.

In Episode 11 one can see William's and Mary's past. It is stated, that he is the only child, which inherited his parent's powers as psychics. Mary did not inherit any special power. During his time in school he often got bullied, but refused to use his power due to a little accident in his past, which he feels bad about. He swore to himself, that he will not use his power until he gets stronger. Later, still in the past, he and Mary are seen in front of the being, which already took Leo's sisters eyesight. There he offers his body to save his sister and gets possessed (most likely). After the flashback you can see him dragging Leonardo, after getting knocked out by some device on his eyes, down into the other world. Soon after he initiates chaos in Hellsalem's Lot by creating explosions on the surface. At the end in the church he is seen to sit next to an unconscious Mary. He then proceeds to point a gun at her chest and. After that you can see and hear, from a certain distance, that there is a shot. However it is not shown that Mary took the bullet to the chest and died.

Power & Abilities
As Black, he has been seen to have psychic powers as seen when he stopped a coffee from spilling on Leonardo but it seems he can only use this for a limited amount of time.

King of Despair is shown to be much more powerful, and more in control of his power. His power makes him able to kill without even touching something.

You look at him he kills you!
