Saint Lucia or Saint Lucy is the Christian patron saint of the blind. She was a devout young woman whose belief in consecrating her virginity for God and whose urge to spend her life on alms enraged her pagan betrothed, who then reported her as a Catholic to the magistrate. After her refusal to burn a sacrifice to the emperor, she was immediately sentenced into execution. Christian traditions state that her body was filled with holy spirits that the guards were not able to take her in by force, and they decided to cut her throat and gouged her eyes. Even so, she was still able to see and continued prophesising. As a final act, the guard stabbed and killed her. Catholic and Orthodox Christians venerate her now as a martyr and saint.
Putting aside the legend, Lucia is among the few Personas, like Artemisia and Caesar, who are based on actual figures.
Lucia is a Persona of the Priestess Arcana, awakened by Fuuka Yamagishi on a SEES mission inside Tartarus during the Dark Hour, when she uses her Persona to protect her "friend", Natsuki, from two dangerous Shadows. Lucia is notably unique compared to the other Personas, as she is never used actively in battle, but provides tactical support for the team regarding locations and enemy weaknesses. Regardless, her stats increase each time she gains a level. Symbolic of Saint Lucia, her design depicts her as a woman whose eyes and throat are covered with bandages, with her lower body being that of a giant glass sphere in the form of an eyeball.
