In a world where facial features can be swapped, you play as 'The Mysterious Changer', a skilled face-forger whose vital talent goes awry when you accidentally switch faces with a notorious criminal during a high-stakes heist. Now, you must navigate through an underground network of thieves, detectives, and eccentric characters to uncover the criminal's identity and restore your own face before it's too late. As you interact with various NPCs, each with their own motives, your choices will determine the outcome of your adventure—will you regain your identity, or will you embrace the new life in the shadows?
