In a world where the shadows of the living possess personalities and memories of their own, you play as a shadow-walker: a person capable of communicating and collaborating with the shadows of both the living and the fallen. Enter a mysterious city where shadows have begun to mysteriously vanish, leading to latent chaos among citizens. Unravel the mysteries behind each shadow — some have secrets to tell while others yearn for liberation. Engage in dialogue, solve complex puzzles, and make choices that impact both the living and the shadow realm, all while navigating personal dilemmas regarding identity, existence, and morality.
