Three random guys accidentally become the only thing standing between Earth and total conquest. The Dragonars they steal aren't sleek federation tech, they're experimental, unpredictable, and the men piloting them have zero training. This is 80s mecha stripped of academy pomp and military hierarchy; it's three civilians learning to fight a war they never asked to join, one desperate mission at a time.

In 2087, the United Lunar Empire Giganos goes to war with the Earth Federation Military, aiming to seize the planet and bring about what it calls a rebirth of humanity. When Giganos troops attack a colony, three civilian men come across three secret Metal Armor machines known as Dragonars and take them into battle against the invaders. The result is a science fiction mecha adventure built around giant robot combat.
