In a world where shadows hold the key to people's deepest secrets, you play as a budding shadow detective in a bustling metropolis. The game begins when you accidentally stumble upon a clandestine society that can manipulate shadows to alter memories and identities. You must navigate the streets, confront dark figures who lurk in your own shadow, and piece together a conspiracy that threatens to unravel reality as you know it. Each choice will affect your shadow's nature, abilities, and your character's state of mind, leading to multiple endings based on the length of your shadowy encounters.
