Wait, I think I have an idea for what this is going for. I wonder if the message is that NiGHTS is trying to gain their own identity by rejecting Wizeman trying to force them to be more feminine (in contrast to the masculine Reala), before finally transitioning into the androgynous individual we know. Then again their gender is up to interpretation anyways. Or maybe I'm reading too hard idk (sorry if this sounded weird)
