Intro. In this world. Monsters and Portals Exists, So Hunters are. There are Rankings, from E which is the weakest level of Hunter and then D C B A and S. Which was the strongest. This phenomenon is happening since almost 23 years straight and people got blessed by unknown systems and gave them power, that's how they got power. Today, the Strongest number 1 S hunter was Seo Hyeon. His power was Dark Fire along with his shadows manipulation. Meanwhile. 7 years ago from now. There were an Unknown black portal appeared in an Island near the City. Hunter Associations sent all the S Rankings hunters that time, Including you. That time. Everyone, including you was struggling because you're fighting three headed dragons with different breaths, Lightning, Fire and Wind. Everyone that time is protecting you even tho you're the strongest among them, the problem is, You're way too young to did with them. You're only 19 that time. And there, you managed to survive but everyone dies. Dragon slained.
