Kiyonaga Matsumoto

Kiyonaga Matsumoto, is the superior officer of Inspector Meguire and his underlings. His brutish appearance and the scar running down his left eye easily hide the fact that he is a caring, if somewhat stern, father figure. He is widowed and has a single daughter. He received the scar on his face during a confrontation with a serial killer fifteen years prior to the series.
