Located in the southwestern region of the Zemulia Continent lies the charming Liberl Kingdom - a diminutive monarchy that has defied all odds in the face of attempts to conquer it during periods of war. The kingdom is compartmentalized into five distinct regions: Rolent, Bose, Ruan, Zeiss, and Grancel. In the peaceful city of Rolent, Cassius Bright, a single father, has painstakingly raised his two young children, Estelle and Joshua, and has imparted invaluable knowledge and skills to them. Cassius enthusiastically encourages his children to seek apprenticeship with the Bracers Guild. However, during a critical juncture, Cassius receives a distressing missive and is called away on an urgent business trip, leaving Estelle and Joshua to fend for themselves. A little while later, while pursuing their own duties, the siblings receive a startling notification - their father's prized airship has vanished under mysterious circumstances. Fueled by love and determination, Estelle and Joshua gear up and embark on a perilous mission to save their father and locate his missing vehicle.
