In a historic event, Rinko announced to the world the existence of Alice, the first Artificial Intelligence with a human soul, or Fluctlight, implanted into an android body. Meanwhile, at the Ocean Turtle, Higa monitored the condition of Kazuto and Asuna, who had spent 200 years in the Underworld, while Kikuoka faked his own death to avoid the government's scrutiny. Alice interrupted the press conference when she sensed that Kazuto was waking up and rushed to his side. Kazuto revealed to Alice that her sister Selka was still alive, frozen in the Central Cathedral, and asked Higa to delete his and Asuna's memories of their long lives in the Underworld. After recovering from their injuries, Kazuto and Asuna met with Kikuoka, who had a plan to save the Underworld and its inhabitants from being confiscated by the authorities. Higa also had a secret conversation with a copy of Kazuto's Fluctlight that he had preserved before the deletion, who requested his assistance to contact Kayaba, the creator of the Underworld, and find a way to protect it. Back at his home, Kazuto grieved for his lost friend Eugeo, while Suguha comforted him and asked him to share his story with her. The next morning, Alice felt a strange uneasiness and Rinko tried to call Kazuto to check on him.
