Somewhere in the deep mountain ranges, there is a place not properly recorded on maps.

A forest where mist lingers through all four seasons, endless valleys, and a massive waterfall pouring from halfway up the mountain.

Here, strange phenomena occur that cannot be easily explained by human eyes.

When night falls, footsteps are heard on empty paths, and non-existent villages appear within the mist. Reflections in old ponds differ from reality, and people who get lost in the forest return days later as if nothing had happened.

Deep in the mountains, old shrines and training grounds remain, inhabited by people living slightly apart from the world.

They wander the mountains solving strange incidents, train under the waterfall, and sometimes converse with the mysterious beings living in the forest.

Everything that happens on this mountain holds a secret yet to be revealed.

And from the moment you seek this place,

The story of the quiet mountain begins to move, little by little.
