One day, the world turned into a game. "Dungeons" and "monsters" emerged in the middle of cities, while "players" who had received authority from the gods appeared. Se-Jun Lee, the guild master of the Messiah Guild that would bring salvation to the world: "Let us save the world together. Let's put an end to this nightmare." The whole world celebrated the hero's appearance, and I became his comrade. But he wasn't the hero nor the messiah-like being the world hailed him to be. He was just a deceitful person with a secret ambition to rule the world. "You did well. If it weren't for you, I wouldn't have been able to come this far." I lost my life to 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. But this time, it's my turn... to "hunt" him.
