In an alternate 2023, Your Forma, a miraculous "smart thread" technology originally developed to treat a massive outbreak of viral encephalitis, has become an integral part of daily life. However, these convenient devices carry an invasive drawback: they record every sight, sound, and even emotion experienced by their users. For electronic investigator Echika Hieda, diving into people's memories via the Your Forma and hunting for evidence to solve the toughest crimes is all part of a day's work. The problem is that she is so good at what she does that her assistants literally fry their brains trying to keep up with her. After putting one too many aides in the hospital, the top brass finally furnish Echika with a partner on her level, a brilliant yet cheeky android named Harold Lucraft. Does this unlikely duo have what it takes to resolve their mutual suspicions and avert a deadly technological infection from sweeping across the globe before it's too late?
