“Your one hundred-year journey starts here.”

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 anti-AI terrorist group “Toak” tries to assault Assemblyman Aikawa, but Vivi and Matsumoto take action to prevent this tragedy from happening. However, Vivy has no way of retaliating against the relentless attack of the terrorists since she was created to be a singer, and they find themselves backed into a corner…

“I humbly accept. I look forward to a long-lasting relationship.”

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 when they try to attack the island. With “AIs attacking humans” now a fait accompli, Vivy rescues the members of Toak, and heads to the center of the island to prevent further havoc by the AI.

“…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.
