Assistant to Prince Ojin
Kingdom of Misgarth
Yu-Gi-Oh! GX episode 84: "Generation Next"
Linda, known in Japan as Lynd (リンド, Rindo), is the secretary and most trusted adviser of the prince of the Misgarth Kingdom, Ojin. Linda reveals the secret behind the two keys given to Jaden Yuki and Aster Phoenix by Sartorius' good personality. She also assists Tyranno Hassleberry in chasing after Ojin when he prepares to arm their country's mind control satellite (in the Japanese version, the satellite was equipped with a laser that could destroy all life on the planet).
Linda has served Prince Ojin since his childhood. They share a special bond, such as one time when Ojin took the blame for breaking his father's scepter so Linda wouldn't have been fired. Linda cares for the Prince with a great deal of affection, though whether it's like the love one has for a younger brother or actual romantic feelings isn't known.
