Kai then confronts Nina and Anjin in his lap and Nina is about to kill him only for the fail safe to activate and Kai molest and kissed Nina only for Angin to reveal that he sets up a portal that sends his creature and his clones to another world and Kai breaks down about his plans falling apart and Angin sends Nina out of the portal and Kai's final fate is unknown.



  • He bears a similar role to Michael Drucker as both are villains who illegally cloned people and using the clones are resources, both act abusive to their creations, both created their series protagonists by cloning(Nina to Kai and Gibson's Clone to Drucker) and both plan on eliminating the the protagonists they created in order hide their illegal activity, But unlike Drucker, Kai transplants the brains of his clients inside the bodies of their clone rather than giving the clones the memories of their originals as well already being immortal by the age of 240 while Drucker only uplouds copies of his mind into his own clones.
