In the future city of MegaTokyo, rebuilt after a devastating earthquake, powerful robots called Boomers, initially intended for constructive purposes, are now being weaponized by a shadowy corporation known as Genom. These Boomers, some disguised as humans, commit crimes that overwhelm the regular police force.
A specialized unit, the AD Police, struggles to contain the Boomer threat. However, a group of vigilantes called the Knight Sabers, equipped with advanced powersuits, rises to protect the citizens.
Led by Sylia Stingray, and including Priss Asagiri, Nene Romanova, and Linna Yamazaki, these women battle the rogue Boomers, offering a beacon of hope in a technologically advanced and dangerous world.
