Synopsis:
The story takes place in “Nearland”, a theme park where “dreams, hope and science” coexist as an Artificial Intelligence (AI) theme park. This is where the first human-like automated AI was born. Vivy is an AI that sings on stage for park visitors every day, as her directive is to “make everyone happy through music”. She acts wholeheartedly for park visitors. One day, an AI named Matsumoto appears before her. He says he came from 100 years in the future with the directive to “work with Vivy to correct history and stop the war between AI and humans that will break out 100 years from now.” Thus begins the 100-year journey of singer IA Vivy.
Finally, the Vivy series: Fluorite Eye's Song is written by Tappei Nagatsuki (Re:ZERO -Starting Life in Another World-) as well as Eiji Umehara (Chaos;Child).
