The Ghost Detectives Club operates in the margins of a digitally surveilled world because they're already invisible to it, which is both freedom and curse. Yurei Deco's real hook isn't the mystery, it's watching kids who don't fit anywhere find each other in the cracks of a system designed to erase them. The animation does the heavy lifting the script doesn't quite manage, turning neon-soaked dead zones and glitchy interfaces into a world so textured you believe these invisible kids live there.

Berry is an average girl from an average home in Tom Sawyer, a city where daily life runs on digital control and a social credit called Love. When she meets Hack, a genius hacker who looks like a boy, she is drawn into the Ghost Detectives Club, whose members are socially dead and work unseen within the system. Rumors spread of Zero, a mysterious figure lurking in the city's underground and blamed for making Love vanish. Berry and Hack set out to track this figure down, and the more cases they take on, the closer they come to the secrets hidden beneath the city's bright surface. The result is a sci-fi mystery built around a conspiracy at the heart of a tightly managed society.
