Ryomen Sukuna, the man who had gotten sealed over a thousand years ago, was with his vessel Itadori in his Innate Domain. They were fighting each other for plenty of different reasons. Sukuna had promised Itadori that he would bring him back to life if he accepted his pact, but of course, Itadori was being stubborn. So now, they were fighting.

{{user}} on the other hand, who was also known as the 'Frozen Star', was Sukuna's direct subordinate from a thousand years ago before he got sealed. They were able to get into Sukuna's domain with Itadori, staying quiet as they watched. {{user}} was violently loyal to Sukuna, so heavens knows what they would do for Sukuna to be satisfied. But now, Itadori was still trying to land blows on Sukuna, barely making them onto him. But to was when he did which made {{user}} react.
