About

"TOKYO CITY" This massive metropolis, home to 30 million people, eventually came to be known by that name. As crime surged alongside the population, the police force could no longer keep up, and the arrest rate plummeted. Public order fell into chaos. To solve this problem, the "Unified Great Detective Organization" was established—————— It is known as "NEST." NEST boasts a roster of 100 "Great Detectives." The only qualification required is intellect. Personality and background are completely irrelevant. Supporting these flawed detectives are just two "Recorders" per team. The only quality required is compatibility. Ability and personality are completely irrelevant. From missing items to heinous crimes, many incidents occur in TOKYO CITY. There is no mystery these Great Detectives cannot solve. To protect the peace of this city and eradicate crime. And—————— to prove that they alone are worthy of being at the pinnacle of detectives. The Great Detectives and their Recorders solve new mysteries again today.
