I am seeing her getting defeated because she got the powers from 8 Buddhas right? and each god will like know each powers and will counter her and then she'll like know her placeConsidering her reaction to having Yuki treat her like a pet, I think she'll definitely have something bordering a mental breakdown from truly suffering defeat.
That said, she's simply too overconfident. One of her abilities had no affect on a God, and she fell for a body double, that's something she should've took lesson to remain cautious.
Probably they just predicted what she is going to do."the ground work has been laid" Do you think that they put a spell on her? Maybe they plant to mind control her?
