Kano Rintaro, said to be the most unusual sub-division chief in criminal investigation first division, hates exaggerated investigation meetings. He leaves the main parts of the investigation to his subordinates, and sometimes he appears on the scene without a necktie, things that at first glance seem like mysterious actions. Even in the ninth sub-division detective room, he sorts receipts and cooks his lunch, oblivious to other people. It's said that new subordinate detectives won't even last half a year before they quit.
