She isn't taking away free will, just look at the characters from fallen maidens. The were far happier than they were as humans, because their sources of stress and anxiety were gone. I don't think the main character would have a problem with that situation.

If you read the description of the demon realm, you'll notice that mamono and incubi have their property, their own businesses, and lots of other things common to human life. They choose how they live their lives. The fact that they don't go against the demon lord means they simply don't think overthrowing her would lead to a better life.
