The mightiest hero, holding both the supreme title of “Magic Saint” among mages and “Sword Saint” among swordsmen, returns to the world 1000 years after becoming a legend! Barua Wesgarden, the “Magic Sword Saint” who mastered both magic and swordsmanship and etched his name at the pinnacle of human history, once faced the absolute Demon King Giranhel in a battle to determine humanity’s survival.

For 1000 years, Barua’s soul remained bound to the world, burdened by the regret of dying before achieving his goal. But when a boy named Direa Wesgarden, who idolized the Magic Sword Saint, is fatally attacked by monsters, Barua seizes the opportunity to return to the living world by inhabiting Direa’s body. Now, as Direa—who was once considered a failure—Barua, the legendary Magic Sword Saint, must navigate the world of 1000 years later. This time, can he truly protect the peace of humanity?
