At the western end of the continent, a region called Diazfeld was suddenly invaded by the superpower Alkyran. The attacked Kingdom of Ianmad offered his brother Prince Rustat as a hostage in exchange for a consensus. The remaining younger brother, Prince Leome, is a master of swords, but a weak person with a reputation for being loose. He vows to protect the country until his brother returns, but the exhausted kingdom is targeted by neighboring countries, and the assassination of his father and the rebellion of his old vassals are threatening one after another. Can Leome really protect the kingdom? On the other hand, the born hero Rustat is steadily increasing his fame with his sword, courage and immortal body, even in the enemy territory.
