How about playing Ideon theme or End of Evangelion theme while doing her battle.

There’re a few candidates whom I wanna listed as immune to her NP - fully immuned as no effects or damage. Those are the ones who have not experienced death: like Emiya, he’s from the future. Scath, and most other deities who has never experienced death. And they will deal extra damage to her as well.

I think she’s going to be a raid battle boss. Her HP is infinite, and each time you fight her the battle will end after like 10-15 turns or if all you team has been wiped out. She will drop a ton of mats and QPs.
