1) Police investigations of cases through good interrogation techniques.
2) Female leading character for the drama.
3) While micro gestures (being the main theme of Silent Voice) is not used in Kinkyu, the usual techniques of interrogation remains the same, e.g. Fight, Flight, Freeze or Fib Response is explained in the dramas.
4) Most of the action happens within the Police Station.
5) Cooperation with other police departments, not concentrating on interrogation to resolve criminal cases.
