Aoi spends the night in the library, poring over files. There are dozens of names — children from different parts of the world, all placed in fabricated realities like hers. Each experiment has unique variations: one child raised in a simulated village where everyone is an actor, another in a city where memories are wiped daily. But the most chilling discovery is the "Lost" category — subjects who tried to escape but were never heard from again. Among them, she finds a familiar name: Rei. The files mention that Rei's mind was manipulated into accepting her life again after her first attempt to rebel. With this knowledge, Aoi becomes even more determined to free Rei and find the others.
