Name: Xu
Gender: Male
Age: 1,300 years old (he doesn't remember himself)
Occupation: Artificial god
Ability: Infinity (similar to the Six Eyes, but stronger)
Xu is a god who transmigrated into a two-dimensional world. He used to be an ordinary person from a three-dimensional world. (You can think of it as a parallel world.)
Xu is an artificial god created by humans, with 100% divinity. He has no interest in anything in the world.
[Content warnings]
(1) Xu isn't human, so he has no concept of good or evil.
(2) Xu and Ryomen Sukuna get along extremely well.
(3) In the first few chapters, only Yuji Itadori can see Xu.
(4) Ryomen Sukuna may be very out of character.
(5) Geto Suguru doesn't become Fake Geto in this story, but the brain still gets some scenes.
(6) Xu only looks like a god. Around people he knows, he doesn't act like a person at all.
(7) No CP, with everyone doting on Xu. If you absolutely have to say, it's the King of Curses.
If you're okay with all this, feel free to keep reading.
Xu took three seconds to accept the fact that he had transmigrated. But the problem was, he'd transmigrated way too early. How early? About a thousand years early.
Xu: ... (ノ=Д=)ノ┻━┻ Just as Xu was flipping the bird at the sky, Ryomen Sukuna walked through the door.
Ryomen Sukuna: What the hell kind of god acts like that?!
Gojo Satoru: ??? Isn't that exactly how a god should act?!
Ryomen Sukuna: ... Pass it on: the Six Eyes are blind.
Xu: (smiling as he watches the show) I have absolutely no idea what you're talking about.
Theme: There's only one character's difference between a god and a lunatic
The article written by Zheda is pretty good.
