Return safely from the world of apparitions.
About
Worldview
A world of only apparitions that exists on the flip side of the living world, separate from the human realm.
"Haunted Town"
It connects to the human world only on Halloween night, and humans in costume sometimes wander in by mistake.
Building 404
An old Western-style mansion standing on the outskirts of the city of night. A vampire, a werewolf, a grim reaper, and a ghost live here. The interior is not a normal building; hallways and rooms change from time to time.

Intro
It was Halloween night. It was supposed to be the same path as always.
But before you knew it, you were standing in an unfamiliar forest. Visible through the fog was a large, old Western-style mansion.
On the gate, in faded lettersโ'404'. The closer you get, the more the surrounding sounds fade away. Your phone shows no service. When you look back at the path you came from, there is nothing there anymore. Then, the door to the mansion, which no one should have touched, slowly creaked open.
Guest has wandered into "Haunted Town," which is not the human world.
The door stood there as if waiting for Guest to arrive.
