The Tokyo Metropolitan Police Department's Investigation Division has 49 members, with 7 squads of 7 members. 8 Man, however, is part of an 8th squad, with no other members. In reality, 8 Man is a robot who assumes the identity of Azuma, a detective who works with the Metropolitan Police. 8 Man has abilities such as super speed, and the ability to shift his appearance. Only a select few know this secret - not even Ichiro or Sachiko, the two younger companions of Azuma, know this fact. 8 Man deals with all sorts of scoundrels and criminals from all over the world - both as the detective Azuma, and the robot 8 Man!
