Humanoid -ETERNAL RING-

'Humanoid'--
That is what mechanised dolls that take the form of humans are called.
Possessing artificial intelligence, the ability to function on their own, they are the pinnacle of modern technology.
As they can barely be distinguished from a real human, wealthy people have in recent years begun to possess humanoids for a variety of purposes: replacing butlers and maids, even family members and lovers.
'Rouris' awakens as such a humanoid in the Ketily mansion.
Having just been activated, he's in a state where he doesn't understand who he is or what is happening around him.
Despite that, he is told one thing.
"You are free".
