Vivy -Fluorite Eye's Song-

Vivy, the world's first autonomous humanoid AI, sings at the NiaLand theme park. One day, AI Matsumoto comes to her with an important request from 100 years in the future.

One of the causes of the war between AI and humans in 100 years is the death of a politician named Aikawa, so Vivy and Matsumoto try to prevent the tragedy from happening.

After the incident with Assemblyman Aikawa, more people begin coming to see Vivy perform on stage. One day, Matsumoto urges Vivy to board the Sunrise space hotel with him, and they travel to outer space.

Vivy meets Estella, another AI, and doesn't believe what others are saying about her; someone takes over the hotel where Estella works.

Audiences for Vivy's stage performances grow after the Sunrise incident; Matsumoto appears again and tells Vivy that AI technology is advancing faster than what was recorded in history.

Vivy and Matsumoto shut down Metal Float, but with drastic consequences; Vivy tries to prevent further destruction.
