Kusakabe says since Sukuna took over Yuji's body & used his CT, Yuji's body now remembers Jujutsu of a Special Grade
So they plan to do same with soul swap training. Kusakabe will first swap with Yuji's soul & teach basic CE manipulation & Simple Domain to Yuji's body
Ui Ui asks them to think wisely make the pairs for soul swap training cuz with the limit of 1 month, he can only swap twice in this duration
