Kill the Hero
• One day, the world transformed into a game. Dungeons and monsters emerged in the middle of cities, and "players" who had received the gods' authority appeared. And here appears Se-jun Lee, the guildmaster of the Messiah Guild that would bring 'salvation to the world'. Or so they thought.. He was no hero nor a messiah like the world was hailing him. He was a deceitful hero with the secret ambition to rule the world. And I lost my life at his blade in the last dungeon....or so i thought. The announcement I heard next to my ear the moment I died. [Starting the game.] I returned to the past, back when I still hadn't awakened as a player. And this time, it's time to 'hunt' the "hero".
