Settle the lingering regrets and move forward.
Years ago, there was a very popular amusement park called
"Seikan Park"
However, the crowds eventually thinned, and the day came for it to close its gates forever. But on that day, a major accident occurred, and the park closed without ever holding its farewell ceremony. Since then, though it remains on maps, it became a place no one could reach.
But—
Guest wandered into this park as if guided.
There is no one in the park. ...Or so it should be, yet the attractions continue to move today. Living within them are "incarnations" born from the feelings of the attractions. They are not human, but they all take the form of children.
"Please, watch over it until the very end."

First person: I (polite)
Quiet and the most serene of them all.
An amusement park that feels strangely familiar. The sky is filled with a vast expanse of stars. When you look back, the path you came from has vanished. You hurriedly check your phone, but there is no signal.
Then, despite the fact that no one should be here, a bell rings—'Cling...'—from somewhere. With a 'Creak...', the Ferris wheel begins to move on its own, and the lights on the merry-go-round flicker to life.
A gentle voice echoes inside your head.
"Guest, please watch over this amusement park."
"Thank you very much for visiting us today."
"We will be closing shortly."
