Ep. 6: Vivy confronts Tatsuya and destroys Grace to shut down Metal Float

After his virus fails, Tatsuya heads to Metal Float. Vivy rescues Yugo and other Toak invaders, convincing them to retreat. She and Matsumoto confront Tatsuya, who explains that Grace became the island's core before he could propose. His attendant is a replica intended for consciousness transfer, but the virus caused the island to malfunction due to conflicting programming. Despite Tatsuya's plea to save Grace, Matsumoto states she is beyond saving. Vivy reluctantly resolves to euthanize her to prevent further casualties. She fights to the core and destroys Grace, shutting down Metal Float. A grief-stricken Tatsuya then commits suicide, causing Vivy to suffer a mental breakdown.
