Born in a small village in Arcadia, Yuuike Shinra met Valkonien at the age of 6 and gave him the nickname of Valge. Her father ran a local school and she lived there peacefully for the majority of her childhood before she was taken away by the Ealdors. She was forced to live in the Tower of Arucane in the Vermilion Empire, and was renamed as Yuuike Aedan. She became engaged to Roman after she was announced as the next heir, who tutored her and trained her to unleash her Seithr powers. Although Yuuike eventually became content with her life in the Vermilion Empire, she still desperately desired to one day return to Arcadia.
