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.”

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 group “Toak” tries to assault Assemblyman Aikawa, but Vivi and Matsumoto take action to prevent this tragedy.

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.

Estella, an AI that works at space hotel Sunrise, is suspected of attempting to make the hotel crash into Earth.

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.

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.

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.

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.

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.

It has been five years since Vivy has returned and Diva has disappeared. Vivy is being exhibited at the AI museum, and is faced with her defect of being unable to sing.

After awakening from her long slumber in the museum, Vivy witnesses a horrific scene where humans are being massacred by AI. The war between humans and AI has broken out, and amidst the confusion, Vivy meets up with Matsumoto.

Based on the calculations of the Archive, humanity is now on the brink of extinction. As the countdown to human extinction begins, Vivy and Matsumoto decide to join forces with Toak in order to plan a strategy to break into Arayashiki.

As the first AI to utilize her own creativity and being the AI that has had the most contact with humans in the one hundred-year journey, the Archive entrusts Vivy with a choice that will determine the survival of humanity.
