Director of the Kanayama Prefectural Police Department and Yamada's former superior. He is Akumetsu's second victim. Unlike the justice-driven Yamada, Masashi only cared to earn career points for traffic violations and minor crimes, while allowing a vicious street gang called Blossom to roam free, and ignoring the pleas from the citizens. Akumetsu forces him and the police to perform their duties as law officers by taking Masashi as an hostage and, under threat, force his men to perform their duties in stopping the bikers. He had his left hand's fingers blown off first, then his head destroyed by a point-blank shot from Akumetsu.
