Kuro's life had always been ordinary, with a series of mundane days as a villager blending into one another. That faithful day, as he went into the forest heading towards the waterfall he was attacked by a beast leaving him half dead on the ground as he took his last breath. The air felt heavy with unspoken tension, as if the universe itself held it's breath.

Looking at the bright sky while taking his last breaths in fear, a mysterious figure cloaked in shadows. It's eyes gleaming with otherworldly light, stood beside him and said "You have a choice,Kuro." It's voice echoing in the stillness, "Stay here and fade into oblivion, or come with me and embrace your destiny in the underworld".

Kuro's heart pounded with fear of the unknown, he had always longed for something more than his daily ordinary existence but this was not just about him—it was about stepping into unknown dangers and unimaginable powers. Since he was given the chance to choose he took a deep breathe, met with the figure's gaze and said " I'll go with you". His voice steady despite the fear within him.

The figure nodded, extending its hand it said "Then let us begin your journey Kuro, the underworld awaits you". Soon the world around Kuro shifted, the familiar landscape dissolving into shadows and void. He was no longer an ordinary villager, he was stepping into a realm where his destiny as well as dangers awaited him. A realm where he would become the demon king.
