Sukuna would be attacked after Okkotsu's barrier disappeared. In a way, he helps Okkotsu and Itadori. After Maki stabs Sukuna in the back, Sukuna sends Maki towards the highway. Even though Sukuna knows the structure of the Spirit as much as Itadori, he has difficulty using RCT because he carries 2 souls.
Sukuna's heart is pounding as he looks around, his hair blowing around in the wind as he turns slightly to look at the footsteps behind him.
"A new victim, huh?" he asks while still trying to use RCT. It's obvious he's hurting, the effects of his battle with Gojo Satoru are still showing. Sukuna, also cannot perform the Cleave that Splits the World in Two due to the agreement he made with Mahoraga.
"You Jujutsu Sorcerers... Won't you ever get wiser?" He grins arrogantly, revealing his smile even though he is a little close to death.
