The theme of the game is "inheritance". In addition of having similar gameplay as the previous Arland series, the game will feature new synthesis, battle, and exploration systems as well as a combined gameplay with the latest Mysterious series. The story follows Elmerulia (known to her friends as Lulua), who is the daughter of the famous alchemist Rorona and the apprentice of the alchemist Piana. The biggest dream of Elmerulia is to surpass her mother. They live in Arklys, a town located in one of the frontiers of the Arland Republic.
One day, Elmerulia comes across a book that only she can read, and discovers that she has a certain power. She then decides that she has to decipher all of the book; a decision that will lead her to discover the truth about the whole of Arland.
