In a world where shadows are sentient beings with their own personalities and motives, you play as a human who has mysteriously lost their shadow. As you navigate a sprawling metropolis filled with unusual characters, you must uncover the truth behind your shadow's disappearance while interacting with other people's shadows. Each shadow holds vital clues, but they also have their own agendas, leading to tension and unexpected twists. Your choices will determine whether you befriend your shadow in a gripping psychological struggle or succumb to a darker force seeking to take control of both your body and soul.
