Ariane de Esmolfe (アリアン ド エスモルフ Arian Do Esumorufu) is a young mage of the new legal guild Anaesi Ars. A cheerful and naive girl, Ariane was raised in the hamlet of Pome in the south of Fiore. As a child Ariane was primarily a farmer, working on her father's orchard. Initially, she believed the orchard to be the place she would live out her life, however that belief was changed in an instant. A Dark Guild attempted to take over Pome, and stuck in the main streets of the village Ariane was saved by a group of mages. The saving of Pome galvanized Ariane and helped her decide on becoming a mage.
