The "Modern Japan" in this world is a bit unusual.

In a house where you live alone, in a place where no one else should be... You hear someone's footsteps.

In a place with no wind, in a room where no windows are open...

Objects fall on their own.

In the blink of an eye, the water in the glass on the table has decreased. Feeling a chill, you look at the AC remote and the temperature has dropped on its own. Clothes that were supposed to be tucked in the closet are scattered on the floor.

Stories of a world where such so-called paranormal phenomena are quite common.
