Mokutaro Shiroyabu is a detective of the 25th Ward Heinous Crimes Unit and one of the central characters of the Correctness storypoint of The 25th Ward: The Silver Case. He also appears in case#25:whiteout prologue of the 2017 edition of The Silver Case.
Shiroyabu is a reckless and overconfident cop. As a Central Police Department officer, he shows enthusiasm to the concept of dying in the line of duty, tries to shoot Akira based on presumption and shows fanboyism towards Tetsugoro Kusabi. As an HC Unit detective, he is considerably more competent; however, he is still prone to recklessness and is frequently berated by his partner, Shinko Kuroyanagi. When left on his own devices in #03 boys don't cry, he acts unnecessarily aggressive and violent towards both his enemies and civilians.
After death-filing and being "overpowered" by Kosuke Kurumizawa, Shiro mellows out considerably and begins carefully planning out his actions. He gains an existential awareness of Kamui Uehara and his own past selves. He is still dangerous, however, and has to be talked down from this state by Kuroyanagi.
