Solo leveling: Usurper

This is the story of a man that usurped the power of the shadow monarch that was destined to belong to Sung Jin-Woo. With the new opportunities that were opened to him, this man would try to live to the fullest and made a name for himself. This is the tale of the new Shadow Monarch. Disclaimer: I'm just a fan that want to share his ideas, so I don't own the right to Solo leveling and its franchise.
