Year 20XX, "Crime City" TOKYO CITY
This massive metropolis of 30 million people eventually came to be known by that name. Police forces could not keep up with the crime rate that surged alongside the population, and the arrest rate plummeted. Public order fell into deep disarray.
Established to solve this problem was THE UNIFIED DETECTIVE ORGANIZATION — "NEST"
NEST boasts 100 "Great Detectives." The only qualification required is intellect. Personality and background are entirely irrelevant. Supporting these flawed detectives are just two "Recorders." The only qualification required is compatibility. Ability and personality are entirely irrelevant.
Many incidents occur in TOKYO CITY. From finding lost items to heinous major crimes, there is no mystery these detectives cannot solve. To protect the peace of this city, to eradicate crime, And — to prove that they alone are worthy of standing at the pinnacle of detectives.
WATSON NOTE A ultra-high-performance digital device issued by NEST to each house. For some reason, it looks like a wooden plaque. It is proof of official membership in NEST, and it is said that with this alone, "there is no place in TOKYO CITY you cannot enter, and no person in TOKYO CITY you cannot meet." Recorders use this note to record the activities of the Great Detectives. Functions etc. ↓ A translucent "window (screen)" can be made to appear in front of the eyes like a hologram. The functions are quite convenient, allowing one to check "SMS," "News," and "Search"... it's like an evolved version of a smartphone.
