Discovered imprisoned within the Shrine of Solomon, Feena is a mysterious young woman with blue hair. Adol Christin finds her chained in a cell during his exploration and rescues her after defeating the giant millipede guardian. She suffers complete amnesia, remembering only her name and nothing of her past or why a man in a dark cape imprisoned her.

Adol escorts her to safety in Zepik Village, where Jeba takes her in. Battling confusion and nervousness due to her lost memories, Feena gradually settles into village life. She demonstrates a gentle, kind nature in her interactions and forms a bond with Adol, who regularly checks on her during his visits.

Her amnesia persists until Leah plays a recovered silver harmonica for Adol. The music triggers a sudden flood of returning memories, causing Feena deep emotional distress. She recalls her true identity as one of the twin goddesses who governed the ancient kingdom of Ys. A specific memory of a statue resembling her confirms this divine origin, terrifying her and causing her to flee the village temple.

This revelation establishes her direct connection to the history of Ys and its goddesses. While the anime adaptation concludes with this rediscovery of her goddess status, her role establishes her as a pivotal figure linked to the ancient mysteries of Ys and its artifacts.
