Who is Th personal secretary from A Wild Sheep Chase and what is their importance?

As the right-hand man of the most powerful figure in Tokyo, the personal secretary of the Boss is a powerful man by himself. He dresses very formally, with gloves, a jacket, and a tie, and speaks with nearly perfect accent, although it is clear he is a foreign-born man. In addition, he takes his role very seriously. With the eminent death of the Boss at hand, the secretary takes it upon himself to find the source of his Boss' power, or his Will. In doing so, he has located the main character. As the story continues, however, it is revealed that the secretary has also discovered the Rat, and knows the sheep has entered the Rat. The secretary knows of the mystical sheep, and of his powers, and desires to obtain those powers. In the end, however, his sixth sense and high intelligence do not save him from the same fate as the others who encounter the sheep. His death at the hands of the main character in partnership with the Rat seem a harsh end for such a man, but his goal of power and status led to his demise.
