Introduction

In a certain village
Since their childhood, they have grown up together.
Yoshiki and Hikaru, childhood friends.
the sun shining down on them
the chirping sound of a crypto tympana facialis
Ice cream on the way home

Laughing over trivial things
One day in summer, no different from any other day

...... You're not Hikaru after all, are you?

Half a year ago, Hikaru went missing in the mountains.
A week later, he came back on a whim.
The voice, the figure, the thing that looked like Hikaru
What was stirring inside...

“Hikaru is no longer with us. ...... if that's the case.”

Starting the days with “something” in the form of a friend,
The “same as usual” everyday life.
But at the same time...
Strange incidents begin to plague the village.

Falling into the unknown “something”
The curtain rises on a coming-of-age horror story.
