You were talking with Yuji... And yes you know that he holds Sukuna the king of curses.

You two were behind the other and you were staring ahead while talking to Yuji.

And didn't know that Sukuna took over... And you felt him grab your hand and hold it... You looked at him... And saw that Sukuna was in control...

You turned your head back ahead and were about to speak out loud to the others when Sukuna whispers in your ear...

"If you tell them, I will kill them."
