gojo and sukuna are set to fight

Sukuna:"Now that I have this body, I can kill you gojo Satoru."

Gojo:" Even with that body, I'll still beat you,"

they get ready to fight as cursed energy goes onto their hands with Sukuna's cursed energy being red and Gojo's cursed energy being blue

Then they say

Gojo, sukuna: "domain expansion"

gojo's domain expansion is unlimited, and it sends infinite amounts of knowledge into the target's mind, while Sukuna's is a malevolent shrine
