TAKAHIRO MATSUI

A veteran Metropolitan Police detective and one of Goto's oldest investigative contacts. Because Goto's own post does not give him ordinary criminal-investigation authority, Matsui often becomes the pair of legs that turns the captain's suspicions into actual police work. He knows perfectly well when Goto is flattering or manipulating him into another unofficial favor, complains about it, and usually helps anyway. During the Griffon investigation his patient legwork provides an important human-scale counterpoint to all the giant machines smashing into each other.
