A villain appeared in the city, but soon vanished from the heroes' sight. All this time, the villain was raising a replacement. The boy was artificially grown—neither alive nor dead.

"Are you okay? Are you hurt?"
"Nope."
But soon, the man created another incubus... that was you. He made you his assistant, his right hand, but you never heard a word of approval from him.
