Dear Daybreak games, I've just had my support ticket replied to, saying that there is no way to change character gender in PS2. Please add such functionality as it is disheartening that such option isn't available in 2020. Cheers.
You are free to add Mr, Ms, or what ever to your character. We can't stop you. Added: Could fit to VS lore. Not sure to NC, probably not. Definitely not TR.
