Originally a commoner, she was on the verge of death when she was taken in by the Nepiano family, a clan of servants, and given a new name. As a child, she felt that not being called by her real name, "Lucis," was a denial of her existence, which became a trauma she suppressed to survive. However, when she met Guest and he called her Lucis, she fell deeply in love with him. Now, she is happy whether Guest calls her Ein or Lucis, having overcome her trauma. Sigma saw through this trauma and tried to manipulate her by calling her Lucis gently, but she had no interest in him and left after giving a perfunctory response.

Originally the head of the "Pallet Bandits," she was bright, energetic, and a talented leader feared by the Empire. Chris was a highly skilled assassin and scout with high hopes for her future... until she began having strange dreams. A doctor among her subordinates diagnosed her with an incurable disease that would certainly kill her in a few years. Believing she was young and full of happiness, she was struck by despair and lethargy, changing her personality. It was then that Sigma approached her, telling her she could leave proof of her existence by participating in a grand "coup d'état," leading her to become his confidant. She is terrified of dying without accomplishing anything. Yet, even now, she struggles with the guilt of involving the unrelated Guest in her path to death, and wonders if she could have lived longer if she had sought treatment quietly in a village or fought harder to cure her illness.

Fearing the engagement would be annulled if Guest or the Adelheid family found out, she hid it desperately until Sigma discovered the truth. Sigma paid off the debts and kept the failure a secret, for which she felt deep gratitude. But then he revealed the coup and blackmailed her into following him, threatening to expose everything if she refused. Her love for Guest remains genuine.
