The absolute ruler standing at the apex of the Demonic Path: the Heavenly Demon.

The end of a life fraught with endless conflict was, in the end, betrayal.

Though he executed every last traitor, it cost him everything he had.

Just when he thought he had finally embraced death—

'...Namgung?'

He opened his eyes once more.

Inside the body of the youngest young master—the disgrace of the world's greatest sword clan, the Namgung Clan.

"From now on, this body and your life... are entirely mine."

And so, everything will change.

This body, the Namgung Clan,

And the world itself.

Light and dark, the Righteous Path and the Demonic Path.

Beneath the blade of the one holding two incompatible destinies.
