After hours of relentless stimulation, Ursula's transformation breaks, exposing Makoto's true identity to the public. Ultimately, Ursula completely surrenders, becoming Meshumel's obedient sex toy whose humiliation is regularly broadcast across the universe. The story concludes with a thoroughly defeated, heavily pregnant Ursula subjected to ongoing public humiliation while Meshumel poses victoriously beside her.
