“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.

“I’ll perform perfectly as usual. To bring happiness to everyone with my singing.”

Diva’s daily performances on the main stage are sold out, and she has cemented her position as the indisputable AI songstress of NiaLand. She is invited to perform at the Zodiac Signs Festival, which will feature AI singers from around the world, but is pulled into a precarious situation during the rehearsal. At that moment, a cube-shaped AI that she has never seen before appears in front of her and…

“Nothing is more important than singing an amazing song…that will allow me to fulfill my life’s mission.”

Diva is astonished when she hears from Matsumoto that Vivy’s mission is to prevent a war between humanity and AIs. He also explains to Diva that his current aim is to stop Ophelia from taking her own life. Ophelia is a songstress AI who just finished an incredible performance during rehearsal. As a principle, AIs are forbidden from self-destruction, so Diva approaches Ophelia to prevent her from committing suicide.
