Shallistera Argo is one of the two protagonists in the Atelier Shallie: Alchemists of the Dusk Sea. She is an alchemist and the daughter of the village chief who searches for a means to save her home, Lugion Village, and travels to the oasis town, Stellard, to do so. She is given the responsibility of protecting a sacred alchemical relic. Before the events of Atelier Shallie, Shallistera has never been outside of her village and thus has trouble socializing. She takes her responsibility to save her village seriously. She eventually takes an interest in what is happening in the world.
