Blue Pill or Red Pill? Vivy is unaware of such choices. As long as she accomplishes her missions, she blissfully contents. The trip to the Metal Float Island is blessed with clean blue sky, a calm sea, a friendly machine, a grand and sophisticate AI manufacturing facility. A sense of security. Yet as the event unfolds, the color of crimson red swallows the island, transforming it into a living hell. Unsettling truth ruthlessly attacks Vivy's reality. What will her choice be?

Intense action scenes. The emotional reunion of the twins. Beautiful soundtrack underneath the starry sky. The central philosophical question of Vivy: Fluorite Eye's Song what does "putting your heart into something" means. Not only the AIs answer it with their earnest actions, the production team behind "Vivy" certainly make it with great passion, too. The Sunrise Arc definitely surpasses the previous arc.

The Sunrise Arc covers episode 3 "A Tender Moon Tempo - A Pleasant Chat with the Stars" and Episode 4 "Ensemble for Polaris - Our Promise". After 15 years, space tourism becomes possible due to AI technical advances. Diva(VA: Atsumi Tanezaki, singing voice: Kairi Yagi), under the identity Vivy, and Matsumoto infiltrate Space Hotel Sunrise to prevent it from crashing. Matsumoto (Jun Fukuyama) offers to destroy Estella, the "most grievously defective AI" according to his database, as quickly as possible. Vivy declines as she tries to understand the cause behind Estella decision. Eventually, the situation becomes more complex as they discover Estella's twin sister is still alive and behind the crash.
