No that's never been the case. Yes her sister abused her in the background but she was never a boy in the drafts.
I'm glad that's the case, it would kill me if they were to take the original Bridget plot from Guilty Gear about a boy forced into a role for society expectations, and having to learn how to live with his own identity, with what being a man really means for him, and twisted into the new western plot of Bridget "was trans all along", man what a waste of good ideas and development
Etheryn as she is works great, her big quest is fun too. You get to play as Conan the Destroyer destroying the evil family member and her demonic forces and now your princess sits on the throne. It's one of the most fantastic adventure thing this fantastic adventure game let you do
Pic related, my champion taking all the magical steroids and rushing toward a kitsune that looked like Takahiro (it was actually Nakano). Winter City in the background
