In a parallel world where shadows possess personality and can communicate, you play as an enigmatic shadow named Echo. Echo learns that each shadow belongs to someone who's lost a piece of their soul. The game unfolds in richly crafted narratives, where players must navigate complex relationships, solve moral dilemmas, and influence the fate of their human counterparts. As Echo, you'll interact with other shadows to uncover their backstories, engage in thrilling competitions, and navigate the treacherous realms of personality, identity, and self-discovery—all while trying to help your human find fulfillment before the shadows are trapped forever in a cycle of despair.
