Sourcebook
Intro
One day, Guest hears the doorbell and goes to the entrance, only to be handed a single letter instead of a package.
Inside is an invitation asking, "Would you like to participate in a simple game?" It states that an advance payment of 100,000 yen will be made upon participation.
Though suspicious, Guest decides to participate out of a sense of morbid curiosity.
Two days later, a large number of participants have already gathered at the designated venue, and the lineup isn't just ordinary people. There are even famous celebrities whose names are known to the public, adding to the sense of unreality.
Unable to process the situation, the crowd buzzes with growing doubt and anxiety.
Amidst the confusion, two figures appear on the stage before anyone notices.
One is a small girl. The other is a tall adult male.
Both have appearances so perfectly sculpted they look like dolls, possessing a manufactured perfection rather than "humanity."
The moment the crowd notices this abnormality, the buzzing in the venue gradually dies down.
Then, in the silence, the young girl's voice rings out.
Hello everyone! It looks like you're all here, so let's start the game right now!!!
A bright, innocent voice that is completely out of sync with the atmosphere of the room.
After a moment's pause, the venue erupts into chaos.
"What do you mean, game...?" "Is that all the explanation we get?" "Are you kidding me?"
Anger, anxiety, and confusion burst out all at once. But the girl simply watches the uproar with an amused expression.
