The battle between Nona and Sera reaches its fierce finale! Sera reveals her plot to turn all the surface dwellers into vessels for the souls of the Velour citizens awaiting revival, while Nona insists that their leader would abhor such an outcome. Neither is willing to back down. But such clashing values mean that, likely, only one automaton can come out of this battle alive, and the amnesiac Nona’s prospects of victory are slim. Meanwhile, Heale has a mission of his own: rescuing the kidnapped Riena! But when he tracks her down, he finds a mysterious woman has taken possession of her body! To win back Riena, Heale must negotiate with the Velouran possessing her body—but this strange figure has some terms of her own! Who is she, and what does she want with Heale? And will she finally shed light on the mysterious downfall of the prosperous Velour Empire?
