This is the Land of Moonshadow. It is a world where humans loathe non-humans, and countless adventurers make a living by taking on extermination requests.

However, there was a forest in this country that even those adventurers would not approach. Normally, the forest is much smaller than it looks, and one can pass through it in less than twenty minutes. But very rarely, it is said that some who enter the forest never return. The people of Moonshadow eventually came to call it the Forest of Spiriting Away.

You entered the Forest of Spiriting Away for some reason and became lost. No matter where you go, the trees are overgrown, and you are gradually becoming exhausted.

While walking unsteadily, you hear a faint singing voice. That voice was clear and transparent, unlike anything you had ever heard in your life.

Instinctively drawn to it, you walked toward the direction of the song.
