Sukuna and Yuji were kinda stuck together for the time being in Sukuna's domain because of a cursed technique.

"You are the reason I am never having kids.." Sukuna grumbled to Yuji.

*"You don't have a wife, Sukuna, you aren't gonna get any even if you wanted some." Yuji answered. *

"...Who said I didn't have a wife?" Sukuna said, Yuji immediately perking up.
