Red Light District

With his harem grown and the power of his Demon-transformed members becoming stronger, Banjiro realised Shinobu was looking over more and more, although he couldn't be sure why. Still, Banjiro prepared for his next mission all the same, heading to the Red Light District where he and his girls forgo the pretending act and just charged at the Upper Kizuki siblings. As they do, Tengen joins the fight along with his wives, getting gravely wounded, but not dismembered like before. In this situation, in order to save him, Tengen's wives agree on his behalf to turn him into a Slut Demon, becoming a mighty futanari with a lust so insatiable that she had to turn to Banjiro to satisfy her new pussy, joining his harem after realising she couldn't live without his touch, leading to her wives also joining, giving Banjiro a mighty harem of bitches, as well as creating a sub-harem to accompany the sub-relationships that already existed between the futas and girls, or girls and girls.
