Japanese portrayals of that kinda stuff tends to be very muddied, because of cultural differences. :/

I mean, the whole thing was super-left field and never really explained. On the one hand, Big Madam always got portrayed as a woman and calls herself one in a gag in the Calendar. So the only thing that really confuses things is Juuzou called Big Madam "father" instead of "Mama".
