In the Future the Earth has become part of the greater universal picture and ushered in a new era where aliens walk alongside humans in everyday life. Of course, with powerful aliens come powerful criminals, and the elite intergalactic organisation tasked with protecting the peace is the S.P.D.: Special Police Dekaranger.
The story focuses on the Earth Branch of the S.P.D, and the five members of its Dekaranger division. Led by legendary S.P.D. commander Doggie Kruger, the Dekaranger are tasked with solving crimes committed by the various alien criminals on Earth. Although the Dekaranger have the authority to execute the most dangerous of criminals, they must attain a "Guilty" verdict from the highest court in the galaxy before they can do so.

The Main Villian/Mr. Big Bad is Agent Abrellar, who is a Complete Monster. He sell lots of weapons supporting galaxy-destroying wars for profit and fun to most of the Alienizers, regardless of how many lives were taken. One galaxy destroyed, he moves to another galaxy to generate profit and destruction. most of the Alienizers have some sort of twisted logic to justify their actions and are shown to have some modicum of standards to their deeds. Aburella, however, treats any and all crime as a business opportunity, and it doesn't matter if you're destroying entire cities, selling slaves, pawning stolen merchandise, or anyingthing else indecent, as long as the price is right, he'll be more than happy to sell you the tools you need to further your enterprise. And his Villainous Breakdown near the end of the series? All caused merely because the Dekarangers were ruining his transactions. Yes, Aburella himself caused a citywide destruction spree and nearly destroyed the whole of the Space Police simply so he could keep his job.
