While searching through the archives, Aoi finds scattered memories that seem to belong to her — old photos, letters, and video logs of her as a child. She sees her parents' faces for the first time in years, but they look different, colder, detached. One video shows them talking to scientists about Aoi as though she were a test subject. Heartbroken and enraged, Aoi smashes the projector playing the video, realizing that her parents were not victims, but creators of her prison. The more she learns about the other subjects, the more she realizes the experiment's scope is far bigger than her small town. It spans across cities, countries, and perhaps even beyond. But why? Who benefits from this? And what happens to those who "escape"?
