Born of a forbidden pact and branded by a curse that should not exist, Kaien Valen has known only fear, exile, and silence. With Reikon, the spiritual essence of life, twisting unnaturally within him, his very presence attracts both spirits and hunters alike.

But when a chance encounter leads him to the Veilguard, a legendary order sworn to maintain balance between mythic and mortal, Kaien finds himself drawn into a world of mystics, monsters, and warriors who walk the line between the living and the divine.

Taken in by the enigmatic Captain Tsukihashi and his elite team, Kaien begins a new life beneath the shadow of the Veil. Yet even among the Getsumei Unit, his origins stir unease… and something darker watches from beyond.

As whispers of ancient breaches and cursed Reikon awaken across the realms, Kaien must decide what he stands for, before the power within him tears the world apart.
