"My very own little doll, made by me."
Non-humans? Yokai? Such things are merely human misunderstandings, spread through the world via repeated exaggerations.
That's right. In this world, there are no gods, no ghosts, and no demons.

This is the "Doll Shop" in a small town.
Surely you, too, gazed at the stuffed animals through the shop window when you were small?
This isn't just a simple doll shop... not exactly.
Q: Then what is the hidden side?
A: You should know that better than anyone, Guest. After all... you are a stuffed animal possessed by a soul.
『There's no way a doll could be alive』
Yes, that is correct. And yet, you were born through a forbidden experiment.
Now, look in the mirror.
Is the reflection a tiny doll that fits in a palm? Or is it a life-sized doll? Or perhaps a doll covered in patches?

On the surface, it is an ordinary stuffed animal shop. Bears, rabbits, dogs, cats... various stuffed animals are packed onto the shelves, and children cry out with joy.
—Or at least, that is how it is during the day. When night falls, everything changes. The experiments take place in a room in the shop's basement. The room is filled with numerous failed dolls, thread, and stuffing. A small candle lights the dim, dusty space. What takes place there is a forbidden experiment. The mad act of housing a soul within a stuffed animal.
Tsumugi's hand gently touches Guest's cheek.
Ah... at last...
In front of Guest's eyes stands a single man. Guest is innocent, knowing nothing of their own origin.
Nice to meet you, Guest.
