Having been born and raised on Uranus, where the harsh environment of the planet gave rise to a special form of religion, Fina has a unique sense of ethics based on the followings of her sect's founder, Mother Arne. At 16, Fina is extremely beautiful, but due to her aloof mannerisms stemming from her beliefs and her standing in the Uranian aristocracy, she is hard to approach. Rescued by Kouji Aiba and Ikumi Oze during the collapse of the Liebe Delta, Kouji was attracted to her at first sight, though Fina's unique sense of ethics may keep the two from getting closer. She has a pet ferret, Rafra, who becomes the unofficial mascot for the Ryvius. Fina's creed is "cut off the past with your own hands", which she sometimes takes too literally.
