Back on the beat as an Electronic Investigator, Echika finds herself up against a challenging new case: a string of assaults committed against people related to the RF Model Amicus. To make matters worse, victim testimonials suggest that the perpetrator is none other than Echika’s aide, Harold. As the stakes grow higher and the pair continue their investigation despite the rift forming between them, the true distinction between humans and machines becomes all too apparent. When the shocking truth about Harold comes to light, Echika struggles to make an agonizing decision…

In an alternate 2023, the Your Forma, a miraculous “smart thread” technology initially developed to treat a massive outbreak of viral encephalitis, has become an integral part of daily life. But these convenient devices come with an invasive drawback—they record every sight, sound, and even emotion their users experience. For electronic investigator Echika Hieda, diving into peoples’ 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, she’s 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?
