All of the fics I've seen where Ranma was assigned female at birth (AFAB) have them identifying as female as living that way as an endgame (i.e. Genoa's Daughter). I've seen fic where Ranma is AMAB (assigned male at birth) and lives as female as an endgame.
But I'm wondering if the reverse is true, a Ranma that's AFAB, but still identifies as male and presents as male as the endgame.
