Simon resistance questions

As I look through Simon's stuff is there any evidence for him being able to resist existence erasure? The closest thing I could find is Nia doing it but that seems linked to her existence as a weird anti-spiral messanger creature rather than with spiral power as she's shown doing it before getting access to it.

However you can make an argument she might have used it to keep herself alive post anti-spirals being killed. Perhaps something in the novelization clarifies this.

Another argument is that he could develop one as he's developed resistances to similar more abstract concepts like probability, time, space, etc.

The other is soul manipulation resistance. I've actually not been able to find any evidence that souls even exist in gurren lagann other than like symbolic phrases like "I believe my drill is my soul." If he doesn't have one than I guess any soul manipulation wouldn't work, right? I could have missed something though

Answers would be appreciated
