Eiyuu Densetsu: Sora no Kiseki

The Liberl Kingdom, located in the southwest of the Zemulia Continent, is a small monarchy that has resisted conquest despite numerous conflicts. Divided into five regions—Rolent, Bose, Ruan, Zeiss, and Grancel—it is in Rolent that Cassius Bright raises his two children, Estelle and Joshua, teaching them independently and encouraging them to join the Bracers Guild as apprentices. After receiving a letter requiring his attention, Cassius leaves, leaving his children to manage on their own. Later, they learn that his airship has disappeared. Determined to locate it and rescue their father, Estelle and Joshua prepare and begin their journey.
