Eating the world's evil messed with Kazura's head but I don't think she got any new powers from it. And even if she did, she wouldn't have done it in the FGO timeline when she is summoned.
Then again she has a aging up thing like Kama, which, like Kama, would (most likely) be part of her ascensions to increase the value of rolling her. However Kazuradrop has to eat her family to grow up and as funny as it would be, I doubt the other Sakura Five are going to be her ascension materials. So they're going to handwave something to explain why she can do stuff in Foxtail that she shouldn't be able to do in FGO.
