BP-501 Shadow-Maru, also known as the Ninja Detective is a multi-transforming member of the Brave Police.

Shadow-Maru's alternate modes include a dog mode, police car mode, jet mode, tank mode, and later a Brave Cannon mode. He originally preferred to operate as a lone wolf, but opened his heart after joining the Brave Police.

Similar to the rest of the Brave Police, Shadow-Maru is armed with a standard-issue revolver and a mechanical Brave Police notebook. His personal weapons include a pair of katanas, various shurikens, a kusarigama, a handheld rifle, Vulcan guns usable in Jet Mode and beam cannons usable in Tank Mode and Car Mode. He also has several advanced spying systems like motion and heat sensors along with top-notch hacking programs that can access satellites or complete feats such as remotely linking his optics with security cameras.

Shadow-Maru first appeared during the hunt for Kagerou, telling the Brave Police to stay out of this case. He initially allowed Kagerou to escape as long as he promised to never cause trouble again, but Kagerou was then captured and had his Super-AI chip removed, which rendered Kagerou's original body as a mindless war machine. Shadow-Maru was forced to destroy the now-mindless body of Kagerou. After having a lead on the whereabouts of Kagerou's Super-AI, which was on a submarine, Shadow-Maru infiltrated it but fell into a trap instead. After a battle that led to the submarine's destruction, Shadow-Maru escaped the submarine with help from Kagerou's Super-AI chip, before Kagerou himself went down with the submarine. After the incident, Shadow-Maru decided to join the Brave Police as Kagerou's last wish was for him to live a good life.
