I don't really believe Regina is actually Cure Ace. It has just been revealed that Cure Ace's voice actress is Rie Kugimiya (awesome voice actress by the way ^_^), which is different from Regina's voice actress, meaning this could be an all new character. Or the could just totally change the voice actor of Regina, which would be unlikely.
