Repulsor boots and bulletproof cloaks. Heat-treated chains on their wrists attached to diamond-shaped titanium blades. The Reikiken, a heated sword made of tungsten that can cut or burn through almost anything.

The year is 2084, and the Hanzo Gear's done a lot to level the playing field against Kingdom Scarlet in the last 38 years. After the Second Civil War destroyed America in 2020, the minorities displaced by the autocratic Kingdom split into three factions, all watching for just the right moment to strike back.

The Kabuto Sanctuary built a network of tunnels during the war, and relied on stealth and sabotage. The Yoroi Alliance, nestled in the Grand Canyon, lay numerous deadly traps to keep the outsiders at bay. The Yaiba Insurrection have continuously engaged their enemies directly, and when they were pushed to the brink of extinction, they created the Hanzo Gear.

The Reds are on the move again, more determined than ever to bring the other factions to heel. John Hamlin is the strongest warrior that the Insurrection has to offer, but when his home is invaded and the people he loves are threatened, captured or killed, the strength that had preserved his peace for years is called into question.
