The Mysterious World: It All Began with a Human-Skin Diary

A diary records the appearance of a mysterious world, inspiring longing in all who read it.

A door connects two realms, from the surface to the depths.

Once the mystery is unveiled, perhaps it should no longer be called a mystery. Perhaps it should be called horror instead...
