Shin Yagami was just another reckless high school dropout—until the day he bought a strange black pendant from a shady pawn shop.

Now the voice in his head won’t shut up. Shadow monsters are hunting him. And worst of all… he’s one of the “Vessels”—chosen hosts for ancient spirit orbs forged in a forgotten war.

Each orb grants immense power… but they come at a cost.

Hunted by Wraiths. Marked by fate. And slowly losing himself to the darkness inside, Shin must fight to survive a world he never asked to be part of. But he’s not the only Vessel. Some want to help him.

Others want him dead.

And some... want what’s inside him.

He didn’t choose the Black Edge. But it chose him.
