ドラゴンクエスト列伝 ロトの紋章

After monsters possessed the king of Carmen seven years ago, the kingdom fell to the hordes of evil. The only survivors were the king's son, Arus, and the army general's daughter Lunafrea. In the kingdom of Loran, a child is born and christened with the name "Jagan," as per the orders of the Demon Lord Imagine. While Arus is honest and good, Jagan is allied with the forces of evil. With the blood of the hero Roto coursing through his veins, Arus must find the courage to become the hero he is destined to be.
