Kill the Hero 

After he’s killed by the righteous leader of his own guild, Woojin gets a chance to start over. This time he’s not interested in saving the world from monsters—he’s got his sights set on revenge! His high-level kills quickly garner him notoriety among the game plebs, while boosting his stats as he masterminds his way closer to the top. But there's something no one can figure out: whose side he’s playing for. Now that he knows how to play to win, Woojin will stop at nothing to destroy the hero!
