I think you misunderstood what I meant, I only identify him as “she” because he is a fictional character, his will does not exist, what exists is his creator's vision of who he is.
like any character in a work of fiction, they can be changed at will, as they are blank pages.
For example, Goku from Dragon Ball, everyone knows he's a man, but what stops me from drawing him as a transvestite, femboy, futanari or even a woman?
When I said it was something personal I meant it literally, I even changed the game's script so that in my game he identifies himself as "she" I changed several dialogues I created an exclusive version just for me where Hazel identifies herself as "she".
Now we have to separate what is fictional from the real, you are a human being and not a character created by someone, you are the one who defines your life and how you identify and not some entity from another astral plane defining your choices, you write your own story.
