Set in a bustling, retro-futuristic city, players take on the role of an amateur detective who discovers an unusual phenomenon: shadows of people appear to have minds of their own, acting independently and sometimes causing chaos. The detective must interact with various quirky characters and their mischievous shadows to solve a series of humorous and bizarre cases that lead to an unraveling conspiracy about a shadow-stealing villain. Each choice players make influences the story's progression and the personalities of the characters and shadows, leading to multiple endings based on their wit and decisions.
