Something similar to that. She believed we "wanted a world where we didn't have to see the truths", or something like that... [To be frank, she never understood that well Izanami's motives] ...and to achieve it everyone in the world would be turned into something more akin to beasts than to humans.

[That's a simple way to describe Shadows, she guesses. Going into much detail seems pointless]

It sounds to me like you know an Izanami too, Terumi-san.
