Chiho, the main character, returns to her hometown, a small country town, for the first time in a while during her summer vacation from college.

So, Chiho and her friends go to the forest behind the shrine to test their mettle.
Her group heads into a forest that is forbidden to enter, but in front of them is an area surrounded by countless paper tapes and shimenawa ropes.
While proceeding deeper into the interior, feeling eerie about the sound of the mysterious bell and the gaze, his friend Kazuya's behavior gradually became strange...?
The moment he reached out to run to his friends, Chiho's body is captured by a mysterious arm...

"I'm glad you kept your promise.''
"The fact that you came here means that you're mine, right?''
