TV Shows like Kyoto Ninjou Sousa File (2015)

There is a special unit of the police (Crime Victims Support Unit) that deals with people who have become victims of a crime and their families, helping out and giving them answers to their questions, assisting in funerals and dealing with the media. This unit does not have the authority to actually investigate anything, though, and that makes it hard to convey the truth to those who want to know it. Togakure Tetsuya, a former detective of the Kyoto Prefectural Police’s First Investigative Division, makes it his mission to investigate on his own record.
