Oda only presented a girl who is obsessed with Oden to the point of impersonation. Anything else is an interpretation through western zeitgeist.

I keep coming back to this, but just no. Because of the bath scene.

I wanted to believe that she wasn't supposed to be a trans character. I argued on reddit that she wasn't, that it was just idolatry. But then the chapter with that scene came out, and it was now unmistakeable that she considers herself a man. She is a transtrender.
