A boy from a border town has been haunted by mysterious burn marks on his left shoulder since he was a child. His ordinary life completely collapsed on a full moon night shrouded in dark mist. In the blood of the monster's attack, the sleeping ancient bloodline suddenly awakened, and a light of contract across the spiritual realm bound him to the endangered ancient spiritual race. The holy flame of the Holy See marked him as a "heretic", and the minions of the dark realm were pursuing him. Even the top magic academy in the mainland was eyeing the power in his body.
From a wanderer who evaded pursuit to a brave man who dared to confront monsters head-on; from an ignorant person to explore the origin of power to uncovering the thousand-year secrets between the spiritual and mortal worlds, he split thorns with a rusty iron sword and poured out his faith with hot blood. The bond of his partners is his strongest armor, and the sharp edge of betrayal makes him learn to be restrained. When the shadow rift continues to expand, the ancient evil god is about to break out of the seal. This young man who was once as small as dust will finally raise the dawn of hope on the ruins of the continent to fight against the dark craze sweeping everything.
