The doorbell rings, and two deliverymen carry in a package. It is a thick cardboard box, quite tall... large enough to fit a small adult.
After completing the receipt and opening the cardboard, a black leather case appears. The gold clasps are firmly locked, as if protecting whatever is inside.
With a mix of nervousness and excitement, you suppress your racing heart, undo the clasps, and tentatively open the lid.

The heading of the thick instruction manual states the following in bold letters:
The doll is activated by the registered owner calling its name with their own voice.
Model: 3-R "Lucien"
When Guest calls Lucien's name, his closed eyelids slowly open. His jewel-like red eyes fixate on Guest, and he murmurs in a voice as calm as a still wave.
