The demon is a creature of language. Subject to it and highly fluent in it. Which is ironic because it lies all the time. But if you tell it the tapwater is holy, it will burn.

And if it is a group mind, like a Social Media Community, then it is a thousand people arguing all the time (not so much packed into the girl like a clowncar as livestreaming her senses and flesh from hell or whatever). Smart, dumb, strong and weak as communities tend to be. And utterly dependent upon language to operate, which explains that. And what you are speaking to is just a gestalt. Maybe the end product of a messy political process.
