In the dystopian world of 2032 MegaTokyo, the Genom corporation, using its powerful androids, the Boomers, has become the world's most powerful organization - far too powerful. But in the shadows of the city lurk the Knight Sabers, a team of four women with remarkable combat skills and highly advanced "hardsuits" that give them a fighting chance against Genom's most powerful combat Boomers. Sylia, Nene, Linna and Priss may be all that stands between Genom and its evil goals.

Amoral Genom executive Brian Mason obtains a satellite weapons-control system and installs it in a Super-boomer, crafting the ultimate weapon. The battle gets very personal when Mason targets Linna's friend for termination.

The battle between the Knight Sabers and Genom escalates when Mason starts using Boomers to encourage urban renewal - on Genom's terms, of course. When the Knight Sabers react, the stage is set for a fateful meeting and a deadly showdown.

A mysterious black car, the Griffon, is hunting down members of a rebellious biker gang. The Knight Sabers get involved when Priss tangles with the Griffon, and events take a high-speed turn.

Five young women die attempting to escape from an orbital colony, and in the resulting mayhem, a highly advanced combat suit goes missing. Meanwhile, a "vampire" seems to be preying on the citizens of MegaTokyo. As the AD Police and the Knight Sabers converge upon the truth, the resulting conflict triggers a countdown to nuclear destruction.

The Knight Sabers have gone bad! They've attacked a Genom warehouse, murdered the guards, and stolen a valuable container of combat Boomers. Framing the Knight Sabers is just a small part of the twisted plans of the mysterious Largo, and their ultimate, humiliating destruction is just a matter of elegant necessity.
