Cast out as a blind, powerless F-Rank by his legendary Hunter family, Aiden Kain was never meant to survive the Rift that swallowed an S-Rank team whole. But when darkness awakens his sight—and a forbidden power tied to the Rifts—he becomes the prey of guilds, mercenaries, and the anomalies themselves. With reality cracking and shadows whispering his name, Aiden must hunt the mysterious Source before it hunts him. One wrong step, and he’s erased—body, soul, and all.over the mystery.
