Riun, the youngest son of the Sermin family, a Great Family of the Drea Continent. The once-peaceful household began its path to ruin following the disappearance of his father and brothers. And at the moment everything collapsed, Riun was captured by the Paton family and met his end after enduring horrific torture. However, where he opened his eyes was not reality, but the endless battlefield and the Playground of the Gods, Adeon. In that place where countless Players lost their lives, Riun grew into the “Ghost King,” a Master Player who mastered every class of Assassin, Necromancer, and Ghost, and challenged the God. Although his life ended in defeat, His story did not end there. The moment he awoke again, He had returned to his childhood at twelve years old, retaining the power of a Player. To prevent his family’s downfall and regain everything he lost, Riun begins to turn reality into his own game board this time. His first goal is bloody vengeance against the Patons, the rival Great Family that destroyed the Sermins and killed him.
