My name is Renn, and I am an inconspicuous night watch captain on the border of the empire. My daily job is to clean up the inferior monsters crawling out of the cracks in the abyss. Until that night when the village was massacred, my comrades who fought alongside me turned into demons in the golden light, and I awakened the power of burning holy light in a desperate situation.
They call me the last bloodline of the "Holy Guardian," the natural nemesis of the devil. But I know nothing about this. I only know that my bloodline is the key to unlocking the ancient seal, and it is also the curse that leads to destruction.
Undercurrents are surging at the top of the empire, and trusted partners may show their fangs in the next second. In this land soaked in lies and betrayal, all I can rely on is this giant sword called "Splitting Soul" in my hand, and a group of companions who cannot be tolerated by the world.
