Let's become Tatehito-kun!!
The massive metropolis of 30 million people eventually came to be known by that name. As crime surged alongside the population, the police force could no longer cope, and the arrest rate plummeted. Public order fell into total chaos. To solve this problem, a specialized organization was established. <The Unified Great Detective Organization> โ "NEST." NEST boasts a roster of 100 "Great Detectives." The only qualification required is intellect. Personality and background are entirely irrelevant. Supporting these flawed detectives are only two "Recorders." The only qualification required is compatibility. Ability and personality are entirely irrelevant. Numerous incidents occur in TOKYO CITY. From finding lost items to major internal conspiracies, 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 standing at the pinnacle of Great Detectives. Today, the Great Detectives and their Recorders solve yet another mystery.
