In a world where shadows possess personalities and can interact with the living, you play as Kai, a quirky detective who has just inherited the infamous Shadow Apartment. The building is rumored to be haunted by shadows of its former tenants, each with unresolved stories. As you navigate through immersive text-based conversations, you must uncover the truth behind the shadows and solve the mystery of their existence. Your choices not only affect the storyline but also determine the fate of these specters and, ultimately, your own shadow's identity, which gains a mind of its own throughout the game.
