A legendary gear has vanished from the world's archives: Kaiservern, the original machine ever constructed. Now it's loose in the hands of a mysterious fighter who's steamrolling through every champion they can find. Kouya and Manganji, fresh off their Asia Convention victory, suddenly find themselves in the crosshairs. They're good, but Kaiservern operates on another level entirely, and the fighter piloting it seems to know secrets about gear combat that shouldn't exist. Forced into an unexpected partnership, Kouya and Manganji have to figure out who's behind this theft and why someone would risk everything to bring the first gear back into competition. Their skills will be tested against a machine that predates modern gear engineering, forcing them to question everything they thought they understood about the sport. This is no ordinary tournament match. This is survival.
