The GENOM Corporation's new plan for the "Urban Renewal" of MegaTokyo involves the use of Combat "Boomer" androids to terrorize the population and induce them to sell their land--cheaply. In other words, it's business as usual at the world's largest company.

Meanwhile, Mason, the siniter GENOM executive whose plans have twice before been thwarted by the Knight Sabers, is determined to discover their secret identities and destroy them once and for all.

When GENOM accidentally kills the mother of a young boy who has been befriended by Priss, reason can no longer hold emotion in check, and the Knight Sabers launch an attack on GENOM's huge, monolithic headquarters--and face a final confrontation with Mason at its very summit.
