i saw somebody ask about a Maid of Mind using the Tsukuyomi and Kotoamatsukami techniques. The latter one is used to give people false experiences and use those to manipulate them. And said person doesn't even know they're being manipulated in the first place because they think they're the one who made the choice. Definitely sounds like a Maid of Mind thing both for their role of Giving, and the use of their powers for their own purposes.

Ooh, I didn’t remember that. God, this kind of thing blurs the line between Mind and Heart though, I wouldn’t be able to tell if a Maid of Heart or a Maid of Mind would fit it better. Hell, even a Maid of Blood could sorta work.
