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?

The now 50 year old Scientific Boys Club decides to built a ship that sails to Mars on the "Ethereal Current" - a thesis of the wife of a club member which claims that the universe is flooded with Ethereal energy. On this stream they travel to Mars in order to prove an old theory about channels on Mars built by Martians, but there is no life. Many years later, when both theories are considered to be nonsense, a Mars expedition discovers a stone with the inscription "Scientific Boys Club 1954".

Inspectors Arata Shindou and Mikhail Kei Ignatov have uncovered a dangerous conspiracy. The Sybil System, the ultimate judge of human character in Japan, is being undermined by a criminal syndicate that is amassing wealth and power in the shadows. Now, Bifrost agent Kouichi Azusawa launches a direct assault upon the Criminal Investigation Department by occupying its headquarters and taking Inspector Shindou and everyone with him hostage. CID Unit 1 supervisor, along with Chief Mika Shimotsuki and former unit members Shinya Kougami and Nobuchika Ginoza, face the task of reclaiming the building and saving everyone inside. Alongside the hostage situation and Azusawa’s demands for Tokyo governor Karina Komiya’s resignation, there is a sinister plot hatching in the background—a secret plan that will force Inspector Shindou to confront not only Azusawa but also his own past. These events slowly bring him closer to unshrouding the mystery that has eluded him and his best friend, Ignatov, for many years.

Thanks to the Sibyl System, the mental states of society can now be measured on a numerical scale. Using these "crime coefficients," a culprit can be apprehended before they ever commit a crime. But is it a perfect system? For Inspectors Kei Mikhail Ignatov and Arata Shindou, that remains to be seen, as their career with the Public Safety Bureau's Crime Investigation Department has only just begun. Shindou and Ignatov are assigned to investigate the crash of a ship carrying immigrants, but they begin to suspect that it was no mere accident. Meanwhile, a mysterious group called Bifrost is observing them from the shadows, but they aren't the only ones who have taken an interest in the two new Inspectors...
