Um, Delphox? Being based on the Oracle at Delphi and all. And Braixen is a magical girl.
How did I not remember that was thought as Delphox's inspiration? I should pay attention more.
Anyways, I agree that Delphox can be seen as having some feminine features, despite the overall inspirations from general magic / magic users. I also thought its appearance is more robe-like, which I associate with both genders of magic users.
