User blog comment:CureKanade/Possible new Cure for Doki Doki!?/@comment-5284898-20130613025941

I just got another idea. From a Chinese cartoon I've seen years ago. So, my theory is Regina = Cure Ace. And this idea is similar to CureAlpha's.

So, Regina is the daughter of Princess Marie Ange and Prince Jonathan (Joe). In the battle between Trump Kingdom and Selfish King, Regina was injured and fell unconcious. Selfish King came over and brainwashed her so she didn't remember about Princess Marie Ange and Joe, and she only knew that Selfish King was her father. After she bonded with Mana and the others, she started becoming her normal self again (the brainwashing spell was coming off) but then Selfish King's power, reaching through the red crystal, brainwashed her again and her eyes turned red because of the brainwashing.

Hopefully the brainwashing spell would come off and Regina would be her normal self again. This is what I think!
