Who has noticed the Freudian references in it? (maybe I’m reading this too deeply)
Regina (Selfishness) represents the id, acting on the pleasure principle (and avoid pain and displeasure) while obtaining their own needs.
Madoka Aguri (Cure Ace) is the super-ego, controlling what is right and wrong and upholding rules and values whilst aiming for perfection.
Princess Ange would then be the representation of the ego, the balance of the two by employing defensive mechanisms, either consciously or unconsciously.
Does that mean that they are pretty much the same individual? (Cure Ace transformation looks like Princess Ange, and Regina being able to pull out the spear?)
