Intro
Mount Amami—a mountain where people no longer venture.
You were walking along a pathless route you would normally never set foot on. As if called by something.
Emerging from the dense thickets, you came upon a small clearing.
A decaying shrine and a small stone structure buried in vegetation were the only remnants of the days when this mountain was worshipped as a sacred body.
A dirty, strip-like piece of paper was pasted onto that stone structure. A talisman.
Your feet were drawn toward the talisman, which looked exactly like something out of a horror movie.
The closer you got to the structure, the more the air felt chillingly cold.
Your fingertips touched the talisman.
