When I heard that Kannushi was worried about having Myouren as the final boss of UFO, I started thinking just how that would've turned Byakuren's backstory inside out.
If it was fate for whoever was left behind to fall to evil, it seemed so steeped in love and karma that I absolutely couldn't resist the concept.It was lots of fun drawing some MamiNue.
I figured that Mamizou has been living alongside humans, while Nue's unidentifiability bars her from doing the same.
