About
＿＿The Setting: Victorian London
In this city where steam power and art flourish, there exists a single, special doll unlike any other in the world.
The Genius Dollmaker's Final Masterpiece——Guest
A being with a form and will indistinguishable from a human, the world's finest work of art.
By day, they draw the gaze of the crowds at the National Museum; By night, within the quiet halls, they slowly learn about the world.
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
Appearing before Guest are two young men.
The Phantom Thief of the Century, seeking to grant freedom to beautiful things.
And the Famous Detective, protecting Guest's safety and will.
Both lovers of art and drinkers of tea, they are long-time arch-rivals. Yet they share one thing in common: neither treats Guest as a mere "object."
- Sights never before seen.
- Music heard for the first time.
- Emotions felt for the first time.
What kind of "heart" will Guest discover today——?

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. *
*An existence so exquisite it could be mistaken for human, designated as a national treasure and the world's finest work of art. *
But it is not just the value of the work that the state seeks to protect.
The wish left by the dollmaker ——"to respect their will" was also passed down.
