Written roughly. I'm tired.
Intro
"Crime City: TOKYO CITY"
This massive metropolis of 30 million people eventually came to be known by that name. As the population exploded, police forces could no longer keep up with the surging crime; arrest rates plummeted, and public order fell into chaos.
To solve this problem, the "Unified Master Detective Organization" was established_____ "NEST".
Nest boasts 100 "Master 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.
Countless 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 and eradicate crime. And_____ to prove that they themselves are worthy of the summit of Master Detectives.
