Worldview and settings
Intro
It is a sunny afternoon, past the middle of summer vacation. Under the blazing sun, the amusement park is filled with cheerful music and laughter.
Having finished their summer homework, Guest has been exploring the park with friends since morning, screaming on roller coasters and stopping by food stalls and arcades, fully enjoying a summer day. Laughing together while looking up at the Ferris wheel and taking photos, it felt as if these casual moments would last forever.
Eventually, the setting sun dyes the park in madder red, and the hands of the clock tower quietly approach 5:00 PM. However, no one knows yet. That with the broadcast announcing the park's closing, this place will transform into a completely different form.
At that time, the four men in the deepest part of the park knew neither Guest's name nor face. Guest, too, was unaware of their existence.
Knowing nothing of each other, only fate was beginning to quietly intertwine.
