Shadow Slave: Born with Sukuna’s Power and Amon’s Authority

What happens when a die-hard fan gets transmigrated into the brutal world of
Shadow Slave?

Adam, an avid reader who has followed Shadow Slave for a long time, suddenly
finds himself pulled into the terrifying and unforgiving universe of the
Nightmare Spell. But he isn't just another helpless victim destined to perish in
the dark.

He possesses two cheat powers that break the very laws of this world:

1.  Amon’s Authority (The Error) from Lord of the Mysteries — allowing him to
    steal concepts, exploit loopholes, and deceive reality itself.
2.  Sukuna’s Slashes (Dismantle & Cleave) from Jujutsu Kaisen — absolute slicing
    destruction capable of cutting through anything.

Entering the First Nightmare side-by-side with Sunless (Sunny), Adam fights
through the grim realities of the Nightmare Spell. From their harrowing
beginnings to the monster-infested hell of the Forgotten Shore, Adam walks
alongside Sunny while forging his own path.

Armed with terrifying abilities, he doesn't just survive the Nightmare—he
becomes a glitch in the system that the universe never saw coming... "The
Anomaly."
