Riyun, the youngest son of the prestigious House of Sermin of the Drea Continent. The once-peaceful family began walking the path of ruin after the disappearance of both the Lord and heirs of the house. And at the very moment when everything collapsed, Riyun was captured by House Paton and, after being tortured repeatedly met his end. However, when he opened his eyes, the place he found himself in was not reality, but Adeon — an endless battlefield and the playground of the gods. In that place, where countless "Players" lose their lives, Riyun grew to become the "Ghost King", a Master Player who had mastered all classes {Assassin, Necromancer, and Ghost}, and had the ability to challenge the gods. Though he met death once more in defeat, his story did not end there. When he awakened again, he found himself in his childhood as a twelve-year-old who still possesses the power of a player. To prevent the downfall of his family and reclaim everything he had lost, He begins turning reality itself into his game board. His first act: a bloody revenge against the great noble House Paton, the very family who destroyed House Sermin and killed him.
