The game begins with a short prologue that sets the scene; a couple exist in a world where people are becoming ‘empty’, which is to say they slowly lose their memories, before becoming ghostly, wandering figures that ‘haunt’ the city. Whilst the female is the main character of the prologue, the narrative soon focuses on the male, who begins in a forest cabin and must make his way through the city to find out what has happened to his partner, before his memories completely elude him and he becomes one of the empty.
