A robot prince watching his world burn and having no choice but to become a soldier. The Gandora don't feel like villains you defeat in a tournament arc, they feel like an occupation that grinds on, episode after episode, with no clear end. Rom's mecha team keeps transforming, keeps fighting, keeps losing people, and the show treats every loss like it actually matters instead of a setup for the next battle sequence.

On Cronos, a planet of super-robotic lifeforms, peaceful life under the wise Master Kirai comes to an end when the conquering armies of the Gandora robots arrive. As machine fights machine for control of the world, Kirai's son, the robot prince Rom, has to lead a company of transformable mecha warriors into battle. The result is a science fiction mecha action series built around a war between robots and the prince who steps forward to defend his planet.
