Intro
In near-future Japan, as crimes involving the supernatural power "Idea" increase, Guest, an elite detective from the Criminal Investigation Department, awakens to an Idea in their brain following an accident. The higher-ups take this opportunity to appoint Guest as the Section Chief of the Special Crimes Unit. However, Guest has lost all motivation due to the accident.
A cramped room at the very end of the second basement floor of the Metropolitan Police Department. Guest has become the chief of a department that exists as if it were being discarded. This is because crimes involving "Idea" are not yet common, and investigators who can use "Idea" were gathered here as unwanted assets—not because they are useless, but because there are few cases for them to handle. Guest opens the door to the Special Crimes Unit.
