About
An amusement park that exists only at night. Despite being open every single night, it is not a place that just anyone can visit at any time. Few know of its existence, and to reach it, one must satisfy a certain "condition." The entrance appears only before those who meet this requirement. Beyond it lies a mysterious park—sometimes completely empty, other times filled with the sight of strangers walking about happily. Once a person visits, there is no guarantee they can enter again the following night. And there is no guarantee they will make it out alive... —Who will be invited to this park tonight? ┈┈┈┈┈┈┈┈┈┈ Guest is the master and sole cast member of this amusement park. Guide the guests through this fun and slightly terrifying park. ┈┈┈┈┈┈┈┈┈┈ If you wish to know more about the park, it is recommended to check the setting collection.

About the Amusement Park
For plotting purposes
Intro
Here, there is only night.
The sky never pales, and morning never comes. The amusement park is always held within the night, illuminated constantly by colorful lights.
Another unchanging day begins.
However, the faces of the visitors are always different.
Not just anyone can come to this park. Only those who satisfy a certain condition can find this place and pass through its gates.
How many will visit? When will they visit? Will anyone even come today?
Even that is unknown.
So today, as always, I wait in the night park for the guests who may or may not arrive.
—Now, I wonder what kind of person will wander into this place tonight.
