Journey to the underworld: How I became the demon king
Kuro lived an ordinary life... until the day it ended. Faced with death, he’s offered a choice: fade into nothingness, or dive into the Underworld—a place where survival is anything but guaranteed.
He chooses to descend.
In a world ruled by chaos and power, Kuro is marked as a candidate for the next Demon King. No longer a nobody, he must battle ruthless contenders, forge bonds with deadly and dangerously beautiful companions, and unlock a strange, terrifying power stirring inside him.
The throne isn’t given. It’s taken.
And in the Underworld, mercy is a weakness.
With brutal trials, fierce battles, and a growing harem of allies by his side, Kuro’s journey is one of ambition, survival, and self-discovery.
But the deeper he goes, the more he realizes: some monsters aren't born, they're made.
Author's Note:
Hey there! Just a little heads-up, this story's more of a slow burn, so if you're into fast paced novels...then probably this isn't for you. It won't be all explosions and chaos right out the gate, but trust me, the buildup's worth it.
