The Thousand-Faced Fox has a weakness...
This was information I obtained only after earning her trust back in the day.
The Thousand-Faced Fox can indeed directly read the memories of any creature of her level and manipulate memories to create cognitive illusions, even turning the target into her pawn. However, there is a contradiction here: it must appear as real as possible.
Memory manipulation might sound impressive, but the more powerful someone is, the harder they are to manipulate. To control someone with ironclad will, immense heartforce must be spent on modifying memories to align logically and suit the target's personality. Only then would there be a slim chance.
This leads to a timing issue—if she has ample time and lingers around you without your knowledge, she can gradually manipulate your memories. No matter who you are, eventually, she could discover your weaknesses.
