Myris is the servant and confidant of the Valkyrie Princess Gwendolyn. Both she and the princess share a very close bond similar to that of siblings or a mother-daughter one. She is very protective of the people who she cares for, especially Gwendolyn (as shown when she stood up to Oswald, stating that she won't allow the Shadow Knight to use the princess). At first she did not trust Oswald, but she quickly trusts him when he goes so far to find a way to awaken Gwendolyn and protect her.
