The game is set in Rieze Maxia, a world where humans and monsters coexist with spirits. The spirits support human civilization by granting wishes, such as the ability to channel mana as spirit power, and in turn are protected by those wishes. The most powerful of these spirits is a being called Maxwell, though its true nature is unknown. In Rieze Maxia, there are two main countries vying for supremacy. Rashugal is an empire with a long history whose free use of spirit power has granted it incredible majesty and prosperity. Auj Oule is a developing country whose power is derived from the control of monsters and the might of its military.
