From then on, Yamato's ordinary life begins to change little by little.

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.

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.

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...
