In this declining future world, the surviving people live by excavating resources from ruins. Over time, a new profession emerged – Airship Knight. These knights navigate the desolate world in airships, exploring dangerous ruins and engaging in battles. The story of the game follows the protagonist, the blonde Airship Knight Dorota, who one day, during a battle in the ruins, accidentally discovers an amnesiac girl named Agate. Agate comes from a long-lost civilization, and her appearance is somehow connected to the sudden activation of robots inside the ruins. This also catches the attention of sky pirates, leading to fierce battles. Fellow knights from the Airship Knights Association—Rita, Red, and Bell—come to help.
