Ermine is a tall, beautiful woman who dresses as a man for easy movement during combat. She is Raven’s half-sister and has pale skin, unlike Raven. Once, she and Raven were sold as slaves to the Prince’s organization, where they met Edgar J. C. Ashenbert. Ermine secretly loved Edgar, but suffered great pain when the Prince abused her to hurt him. Later, Ermine became a spy for the Prince out of fear of losing her special bond with Edgar after he became an Earl. When Edgar searched for the treasure sword with Lydia Ashenbert’s help, Ermine confessed her betrayal and jumped into the sea. She was brought back to life by Ulysses Barlow as a selkie fairy and continued to support Edgar and Lydia in secret. At the story’s end, Ermine joined new friends on a quest for Fire Agate, ultimately asking Kelpie to let her die as a human. In the anime, Ermine is already a selkie at the start and stays with Ulysses Barlow.
