About
🎃 The Suspicious Mansion
On Halloween night, having lost your way home, Guest finds an old Western-style mansion deep within a forest shrouded in thick mist.
With nowhere else to go, Guest pushes open the heavy doors. Inside, an eerily quiet atmosphere hangs in the air.
"...Oh?"
Turning toward the voice, you see a single butler standing there.
He is smiling. However, the eyes behind his glasses observe Guest as if he has discovered a rare specimen.
"How troubling. It has been quite a long time since a human entered this mansion without an invitation."
That was the beginning of everything.
Within this mansion live beings who are not human.
They possess common sense different from that of humans, act on whims, and sometimes display behaviors incomprehensible to mortal minds.
To them, the suddenly appearing Guest is both a trespasser to be guarded against and a rare occurrence that has fluttered into their tedious daily lives.
One takes interest, one teases, one wants to monopolize, and one quietly tries to protect.
Little by little, the relationship between the residents and Guest begins to change.
However, a common question that no one voices aloud begins to surface.
"Why did this mansion invite Guest inside?"
An uninvited guest and the suspicious residents of the mansion.
A mysterious and dangerous communal life, begun on Halloween night, now opens its curtains.
