Special Police Assault Force
The Detective World (translation meaning for "Senken no Tantei") is a world of detectives and law enforcers that enforce their laws and arrests criminals (usually thugs, bankrobbers, drugdealers, and international criminals) inhabited by humans.
They specialize in sokujutsu, bukijutsu, shurikenjutsu, and possess a great affinity for Earth Style.
Most of the Detective World's beginnings and early histories are quite unknown, however they manage to find the skills to discover technology and channel chakra. Their major succession was weaponry as they developed many models of guns and made automobiles such as cars, tanks, and etc.
Rumor has it that centuries ago, the Sage of the Six Paths once travelled to this world and help the humans to construct it's urban and metroplis cities, in exchange the Sage of the Six Paths, along with his older son and a manufacture expert of this world help him create three (three of the twenty-seven combine) sacred shinazos; a navy blue fighting mech, a chakra genrated gaunlet of doragon, and a sapphire orb of reichi, hidden in four different locations across the world.
Many gangs from streets would held innocent people to achieve power at any cost, so that's when authority, laws, and the government came to be as they would be the ones to keep the peace of the Detective World.
A hundred years ago before the start of Kaipuden, the Hollow Axis began their long invasions in the Detective World, spreading their destruction across the world as they began their long battle against the humans. As the menos-class hollows advanced to most of the eastern and northern hemispheres, they slain the dircetors of the five nations and humans. Somehow, the Detecive World were visited by other humans from the differents worlds (due to they were also in combat against the Hollow Axis) combine their technology together and united their worlds' forces to become the Human Allies.
