Shienryu

Earth's search for habitable planets sent massive colony ships — Caravans — deep into space. Caravan 7861 found what the mission was looking for: a planet capable of supporting human life. A colony took root. Ninety-three years passed. Then someone went looking for the Caravans that never sent word back and found out what happened: a militarized regime of alien-humans, commanded by the mysterious Shienryu, had been attacking and conquering the missing ships for decades. The same fleet turns its attention to the established colony — the Mother Planet — deploying invasion forces that build fortresses across the surface and systematically dismantle the civilization colonists spent nearly a century building. The planetary defense force Burn Dragoon is assembled from the best available pilots to push the invaders back.
