Although this may sound back, but I for sure hope so. It adds more to the Alice in Wonderland element that people tend to take, especially the squeal to the original, Through the Looking Glass. If it is because of the mirror, I believe that it would be a great element to this story ლ(´ڡ`ლ)
There's something malice or a someone from their Ancestors put on a Curse on her?
The mirror people are a race of chaos bringers is what I think it was explained as. They purposely try to drive countries into war and destruction. This same method was used on the Kingdom of Diamonds 200 years ago which fell to ruin as a result of the ruler's disastrous personality change.
Is she possessed by the mirror or something?
