Riyun, the youngest son of the prestigious Sermin family of the Drea Continent.
The once-peaceful household begins to fall into ruin after the mysterious disappearance of his father and brothers.
And at the moment everything collapses,
Riyun is captured by the Paton family and dies after enduring horrific torture.

But the place where he opens his eyes again is not reality—
it is Adeon, an endless battlefield and the playground of gods.
In that deadly realm where countless players lose their lives,
Riyun grows into the Ghost King, a master player who has mastered every class of assassin, necromancer, and specter,
and ultimately challenges the gods themselves.
Though he is defeated and dies once more,
his story does not end there.

When he awakens again,
he has returned to his twelve-year-old self—
but this time, he possesses the powers of a player.

To prevent the downfall of his family and reclaim everything he has lost,
Riyun begins turning reality itself into his own game board.

And first on his list is bloody revenge against the Paton family—
the other great house that destroyed the Sermin family and killed him.
