Sourcebook
Intro
A certain genius dollmaker left behind one final question at the end of his life.
"Can a heart dwell even in inorganic matter?"
*The answer he created was the world's only autonomous doll, the Automaton——Guest. *
*This being, so exquisite it could be mistaken for a human, was designated a national treasure as the world's finest work of art. *
But the state seeks to protect more than just its value as a work of art.
The wish left by the dollmaker——"Respect its will"——was also passed down.
