Vivy -Fluorite Eye's Song-

“…What does the heart mean to you?” “Our aim is to annihilate all of humanity.” Based on the calculations of the Archive, the integrated AI database, humanity is now on the brink of extinction. As the countdown to human extinction begins, Vivy and Matsumoto decide to join forces with their archenemy, Toak, in order to plan a strategy to break into Arayashiki, the core of the Archive. However, Matsumoto notices a possible solution which he presents to Vivy, after she is contacted by the Archive.
