Demon Castle Raid Arc

Lore & Background

For Sung Jin-Woo, this raid was the moment his 'System' evolved from a training tool into a weapon of mass destruction. Faced with enemies that dwarfed him in size and power, he was forced to rely on the unique ability to command shadows—a power previously thought impossible for humans. The arc establishes the terrifying hierarchy of the Shadow Monarch's domain, where death is not an end but a recruitment opportunity. This event solidified his reputation as a hunter who walks through hell unscathed, setting the stage for his future conflicts with the National Hunters and the Rulers.

In Their Own Story

The air inside the castle tasted of copper and old blood, thick enough to choke on. Jin-Woo gripped his sword, the metal cold against his palm, as the shadows in the corner seemed to stretch toward him, whispering names he didn't recognize. Ahead, a massive gate loomed, pulsating with a dark rhythm that matched the beating of his own heart. He knew the others were gone, their screams silenced by the darkness long ago. But as he stepped forward, the floor beneath him didn't just hold his weight; it bowed. The shadows rose to meet him, not as enemies, but as an army waiting for a king.
