The year is 2033, and Mega-Tokyo is just beginning to finish recovering from a HUGE earthquake that completely rearranged the face of Tokyo. Part of the recovery is due to the recent advancement of Boomer technology. Boomers (or Bumas, if you`re watching the subbed version) are androids that look, think, and act just like human beings. They can be put to work, perform in the military, or, um, go berserk and terrorize the population.

The corporation responsible for all the major Boomer advancements is a monolithic company called GENOM, whose power seems to grow with every passing moment. GENOM seems to have a rather underhanded secret agenda (to take over the world, of course). With the world dependant on Boomer technology, there doesn`t seem to be much that can resist its power.

Enter the Knight Sabers. This mercenary team of four young women equipped with hardsuits has the firepower and the courage to stand up to rampaging Boomers and the company behind them. Knight Sabers, sanjo!
