Reisalin "Ryza" Stout is the titular main protagonist in Atelier Ryza: Ever Darkness & the Secret Hideout and Atelier Ryza 2: Lost Legends & the Secret Fairy. She also appears in Atelier Online: Alchemist of Bressisle.
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 the their parents and the island. The hideout is named "Atelier Ryza", and becomes her alchemy atelier.
Ryza and her friends have a rivalry with Bos Brunnen and his underling Lumbar Dorn. They used to be friends when they were younger, but after an incident where a young Ryza was at the risk of drowning their friendship fell apart.
Over the course of a single summer the friends share many adventures. This leads them to both face the dangerous Philuscha, but also grow as individuals. Ryza then returns to her ordinary life until three years later, when she journeys to the capital and gets caught up in yet another grand summer adventure.
- "An ordinary girl whose unique characteristic 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. Her whole word is turned upside down during an extraordinary encounter..."
