In a world where shadows have a life of their own, you play as Luna, a shadow psychologist tasked with understanding and solving the mysteries of sentient shadows that have begun to manifest their own desires and personalities. As Luna navigates through a series of bizarre cases, she must engage in deep psychological interactions with both humans and their shadows. Each case takes place in surreal environments where light plays tricks on the mind, and the shadows reveal hidden desires or dark secrets. The choices you make not only affect the outcome of the cases but also determine whether you can save the human characters from their own fears or let their shadows consume them.
