|“||It was hard getting today off, you know?! And when I call you, you never answer, and when you do you just berate me and hang up! Why would you be so cruel?||”|
–Sullivan, Obsolete Dream (CHAPTER 4)
|Location||Pitch Black World|
|Affiliation||Pitch Black World|
Sullivan has medium-length sand colored hair. His eyes, like Kurotsuno's, are bright yellow with black sclera. He wears a black suit and tie with black oxfords. His horns are similar to Kurotsuno's left horn. They form a sort of zigzag pattern and are gray with three black stripes on them.
Sullivan seems to be very childish at times. As shown in Chapter 4 of Obsolete Dream, he is quick to cry when Kurotsuno tells him to leave and when Glasses drags him away after being rejected by Kurotsuno herself.
It should be noted he continues to call Kurotsuno, "Olivia" despite her change in race. He is very loving towards his daughter, and cries easily when she is cruel to him.
In the past, Sullivan's tie was red. It is currently speculated that he is originally from the The Gray Garden world.
- Mogeko Castle - Indirect cameo wherein he made a letter addressed to Olivia.

"To whomever should read this letter:
By the time you read this, I am surely gone.
This castle is dangerous.
You must find some means of escape.
If you cannot escape this place, you will never elude the Mogekos...
They are persistent. Oddly, no matter where I hide, they're always come right for me.
Hide, and hide, and hide...
They always find me soon enough...
And I kill and kill them... but there's no end...
They come one after another.
.....This is no more than a hypothesis, but perhaps they are.....
It seems they're back again.
I know it's futile, but I will run.
While I can still move...
I wanted to say a final goodbye to my daughter...
I'm sorry I've failed as a father...
I love you, Olivia.....
