Demon Slayer: The Demon Slayer Duke
In a world of blood and shadows, a black-haired, red-eyed boy toils in chains beneath the heel of a ruthless noble. He has no name, no past—only the sting of the whip and the weight of servitude. But deep within his soul lies the buried echoes of another life. Once, he was Duke Barriet, a master swordsman who stood alone against hordes of monsters and demons. Once, he was powerful, feared. Once, he was betrayed—stabbed in the back by the man he trusted most, Joseon Irkan, who stole everything from him for the greed of a magic stone mine.
Now, in this unfamiliar world, something awakens within him. A voice, cold and mechanical, rings in his mind:
[Demon Hunter System Activated.]
The system speaks of demons—beasts that thrive in the night, feeding on human flesh. It tells him that he was reincarnated, that it was the one who brought him back. In return, he must slaughter every last one of these creatures. He asks if they are the same as the demons of his old world. The answer is no. These demons are worse.
Bound by vengeance and a thirst for strength, he will carve his own path through this new world. But in his pursuit of power, he crosses paths with Tanjiro and Nezuko Kamado, two survivors of a demon’s massacre, seeking their own justice. Amid bloodshed and darkness, he will forge bonds—not easily, not without struggle—but for those who earn his loyalty, he will be unwavering, possessive, and fiercely protective.
The path of the Demon Slayer is cruel, but so is he.
For he knows better than anyone—trust is a blade sharper than any sword.
