In a world where shadows possess their own personalities and can affect the physical realm, players step into the shoes of a shadowless detective in Quirk City, a vibrant and zany metropolitan hub. As shadows begin to vanish mysteriously, players must navigate a series of bizarre encounters and characters who express their unique quirks through their shadows. Players will gather clues, interact with quirky shadowy beings, and solve puzzles to restore the balance between the light and the dark while uncovering secrets that challenge the identity of everyone involved, all through clever text-based choices and narrative twists.
