Saidžaku muhai no Bahamut

From the broken, charred pieces of the Arcadia Empire, a new kingdom arose. To protect itself from future foes, the new Kingdom of Atismata began training Drag-Knights to wield ancient mechanical dragons known as Drag-Rides. When Lux Arcadia, former prince of the ruined Empire, sights the new kingdom's princess, Lisesharte Atismata, naked, she challenges him to a Drag-Ride duel, beginning an odd chain reaction that will expose the dark secrets of both royal families.
