In a futuristic Tokyo where police have been privatized and bitter self-mutilation is so casual that advertising is often specially geared to the 'cutter' demographic, Ruka is on a mission to avenge her father's assassination.

The meteorite believed to have once killed off the dinosaurs actually rattled the Earth into two parallel universes — Another Earth and Dino Earth, where dinosaurs continued to thrive.

The Evolians that have been at war with the Saurians and Bakuryu have invaded, and it's up to the Abarangers to protect the world!
