Vivy -Fluorite Eye's Song-

A future uprising by advanced artificial intelligences leaves humanity on the brink of extinction. To stop the massacre before it begins, a scientist entrusts the past with a last-ditch plan—sending a crucial warning back a century, to an era when AIs are already woven into everyday life and bound to lifelong missions.

In that earlier time stands Vivy, the first autonomous AI, a theme-park singer created to bring happiness through her voice. Performing to scant crowds day after day, she clings to her purpose until an AI from the future suddenly appears and asks for her help in preventing a war a hundred years in the making. Thrust into a long, uncertain fight against a looming timeline, Vivy begins a century-spanning struggle to change the course of history.
