“My mission is to bring happiness to everyone with my singing.”

Vivy was created as the world’s first autonomous humanoid AI and works at the NiaLand theme park. Her mission is “to make everyone happy with her singing.” While she is singing on stage, she comes into contact with an AI that calls himself Matsumoto. Amidst her confusion, he asks for her help to rewrite history together, in order to stop the war between AI and humans that will happen one hundred years later.

“Hey, can you hear me? Don’t you think this song I’m singing sounds beautiful?”

The ugly truth behind the tragedy that has befallen Ophelia, is that her support AI, Antonio, has taken over her body. With his identity blown, Antonio attacks Matsumoto in order to hide Ophelia’s truth. Kakitani captures Diva and confesses his hatred for AIs while forcibly trying to awaken Vivy who is inside of her. Will Diva and Matsumoto be able to safely fix the Singularity Point…?
