In a region of the Zemulia Continent known as the Liberl Kingdom, a small monarchy has resisted numerous wartime threats. The kingdom consists of five areas: Rolent, Bose, Ruan, Zeiss, and Grancel. In Rolent, Cassius Bright raised his two children, Estelle and Joshua, teaching them independently and encouraging them to join the Bracers Guild as apprentices.

Determined to locate it and rescue their father, they prepare and begin their search.
