you can't revert it, however i will give some advice on how the keypage works. it's the opposite of angela's, requiring a negative qlipoth instead of a positive one, so spam those qlipoth pages as much as you can. along with this, use the apostle keypages that dropped for all assistant librarians. another thing, most of her flow control pages increase her qlipoth by a certain amount every scene, so just don't use too many of em.

alternatively, you could go for the other route to get complete angela's keypage

How should i get that other route?
