An ordinary girl whose unique characteristic is the fact that she is just that - ordinary. Ryza has a wild and tomboyish personality with a strong sense of justice. While she can be stubborn in her convictions, her heart is in the right place.
Ryza lives on Kurken Island together with her mother and father. Rather than to help out on her parents' farm she wants to sneak away to the mainland. She spends her days with her childhood friends Tao Mongarten and Lent Marslink, and acts as the leader of their group.
When Ryza and her friends are saved from a monster on the mainland by Empel Vollmer and Lila Decyrus, she is introduced to alchemy and becomes Empel's student. Ryza starts using her new skills to help townspeople and adventure on the mainland, but her mother disapproves of her hobby. She eventually builds a secret hideout together with her friends, so that the team can focus on their goals away from their parents and the island. The hideout is named "Atelier Ryza", and becomes her alchemy atelier.
