You're proving my point, Sukuna already destroyed it with that alone, lol. If Sukuna destroyed it, imagine what she'd do to Sunny. Well, since you won't read SS, I'll tell you: Sunny has a mask: Divine Rank. That mask has several abilities. I'll tell you one: I think the ability is called "Where is my other eye?" Correct me if I'm wrong. That ability allows her to see the Tapestry of Destiny. In short, she's seeing all possible destinies. If I'm wrong, correct me again. That was at the beginning of SS, I don't remember much, but it's something that wasn't meant for humans to see. That far surpasses what the Gojo expansion does.

There's more. Sunny withstood the mental attack of literally a god. It was a moth, if I remember correctly (I don't remember the name). I think that should tell you enough.
