Evil Spirit Warrior

He has an enviable background—his father is the head of state—yet his life has never been favored. He possesses innate supernatural powers and is the master of the first of the twelve divine stones, the 'Source of Power,' but this power always fails him when he needs it most. He is mediocre, with no martial or magical skills, yet he is chosen by an ancient evil spirit to become its host and puppet. His dream is to be an ordinary person, but fate constantly plays tricks on him, dragging him into extraordinary events and making him the center of attention. How does a man who only wants to be ordinary achieve an extraordinary life? Is his life a blessing or a curse?
