This is the 1987 OVA that proved mecha anime didn't need to be about saving the world, it could just be about four women in powered suits who show up when nobody else can. The action is clean, the synth-soaked cyberpunk aesthetic holds up, the pacing never drags across eight episodes. You're watching the blueprint for what happens when anime takes itself seriously about genre without losing the fun of it.

In 2032, seven years after a massive earthquake leveled Tokyo, the rebuilt city of MegaTokyo owes much of its recovery to Genom, a powerful corporation whose biomechanical Boomers did the labor of reconstruction. Now Genom also builds Boomers as destructive weapons that can pass for humans, and the machines keep going out of control. The AD Police, a special unit set up to handle Boomer crimes, is badly outmatched. Four women from very different walks of life, Sylia Stingray, Priss Asagiri, Nene Romanova and Linna Yamazaki, form the Knight Sabers, a vigilante team whose powered armor outclasses military gear. They stand against Genom and its rogue Boomers in this mecha-driven sci-fi action OVA.
