Vivy -Fluorite Eye's Song-

“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.

“Your one hundred-year journey starts here.” One of the causes of the war between AI and humans that will happen one hundred years later, is the death of a politician named Aikawa. The anti-AI terrorist group “Toak” tries to assault Assemblyman Aikawa, but Vivi and Matsumoto take action to prevent this tragedy from happening. However, Vivy has no way of retaliating against the relentless attack of the terrorists since she was created to be a singer, and they find themselves backed into a corner…

“Relax and enjoy a pleasant conversation with the stars.” After the incident with Assemblyman Aikawa, more people start coming to see Vivy perform on stage. One day, Matsumoto appears before Vivy again, and urges her to get on board the Sunrise space hotel with him. While they travel to outer space, Vivy is conflicted by the gap between what she must do and her true mission.

“I’m bringing this child safely back to earth no matter what.” Estella, an AI that works at space hotel Sunrise, is suspected of attempting to make the hotel crash into Earth. However, as Vivy interacts with Estella and gets to know her better, she begins to see a difference between the information given to her by Matsumoto about Estella. Meanwhile, someone takes control over the Sunrise hotel much quicker than what Matsumoto predicted. Amidst the confusion, Vivy investigates the cause of the situation in order to save the passengers and Momoka’s younger sister, Yuzuka.

“I want to protect your smile, because you love AIs.” After the Sunrise incident, the audiences for Vivy’s stage performances grow day by day. Matsumoto appears once again in front of Vivy and informs her that AI technology is advancing quicker than what was recorded in history. In order to stop this, he states that their new mission will be to shut down the unmanned plant on the ocean, Metal Float. Matsumoto and Vivy rush to meet the researcher who helped to build this plant.

“I humbly accept. I look forward to a long-lasting relationship.” Using a termination program given to them by Dr. Saeki, Vivy and Matsumoto use it to shut down the activity of Metal Float. However, this causes the AI that governs the island to go completely out of control, and it engages in battle with Toak when they try to attack the island. With “AIs attacking humans” now a fait accompli, Vivy rescues the members of Toak, and heads to the center of the island to prevent further havoc by the AI.
