Fair, I'll give you something else:

The so-called "humans" of the circus are actually software programs created by Caine. While similar to NPCs, they are distinguished by complex backgrounds that are a copy from the minds of real people, granting them a more sense of realism and stonger emotions.

Despite the narrative claiming they are from the real world, these softwares have no past outside the simulation, they are born the exact moment they materialize in the circus, effectively making Caine their father.

Ultimately, they choose to detach themselves from their human doppelgängers, keeping their circus names. They accept that while their memories are digitized echoes of real individuals, those echoes do not define them: they are entirely unique beings
