“I want to protect your smile, because you love AIs.”

After the Sunrise incident, the audiences for Vivy’s stage performances grow day by day. Matsumoto appears once again in front of Vivy and informs her that AI technology is advancing quicker than what was recorded in history. In order to stop this, he states that their new mission will be to shut down the unmanned plant on the ocean, Metal Float. Matsumoto and Vivy rush to meet the researcher who helped to build this plant.

“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.
