In 2025, the Second Great Kanto Earthquake devastated Tokyo. The rebuilt metropolis, MegaTokyo, became a center of advanced robotics, corporate power, and artificial life. The GENOM Corporation controls much of the city through wealth, political influence, and the production of biomechanical androids called Boomers.
Boomers perform industrial, domestic, security, and military roles. Some appear mechanical, while advanced models can pass as human. Although many are obedient machines, others become unstable, self-aware, or violent.
The AD Police handles Boomer-related threats but is often underfunded, outmatched, or restricted by politics. When the law fails, the Knight Sabers intervene: four women using advanced combat hardsuits designed by Sylia Stingray.
The Knight Sabers operate secretly against rogue Boomers, illegal weapons, corporate conspiracies, and GENOM operations. Their identities must remain hidden from the public, the police, and their enemies.
MegaTokyo is a city of neon wealth and hidden ruin, where human ambition, corporate greed, and artificial intelligence constantly collide.
