Under the laws of heaven, nothing is truly hidden—and there is no path that allows one to drift freely. Throughout history, every major event has carried a shadow behind it: the Concealers.
Known as Spectres, these beings inherited an ancient art. Their methods shift endlessly, appearing when the world needs saving and vanishing once their task is done.
Nine Spectres discover the legendary land of Utopia, said to grant immortality to all who dwell there. Deep within, they uncover ancient records of the Undying Divine Tree. But none of them expected what would come next.
When the nine enter a forbidden mountain where only one may leave, the others vanish without a trace. The lone survivor emerges transformed—no longer fully human, nor truly Spectre… and the true story begins.
