Prologue: 

The Divine War had raged for millennia, a series of battles fought in silence across realms far beyond mortal comprehension. The rules were simple: conquer all seven dimensions of another god's realm or destroy those unworthy of existence. The winner claimed the conquered realm, and the defeated were erased from the tapestry of reality.

For the Greater Gods, those with dominion over countless realms, the challenge was a matter of pride. The Lesser Gods, with their fragile domains, had no choice but to accept challenges, even when the odds were against them. It was law—a law designed to assert the supremacy of the Greater Gods.

Bianca, the God of Consciousness, ruled over a realm of minds, dreams, and memories. Her dimension was fragile, its power delicate compared to the mighty gods that reigned over other realms. When Trigon, the Demon God, challenged her, she had no choice but to comply. Lesser gods were bound by the rules; rejection was not an option.

Trigon's dark forces swept through her realm like a shadow, conquering two of the seven dimensions within years. Bianca's demigods, beings she trusted with the defense of her world, watched helplessly as their realm fell into ruin. The battles they waged were futile, and every plan they crafted was shattered. It was hopeless—until one of them, Rudeus, a brilliant and determined demigod, conceived an idea that could change everything.

In the deepest recesses of his mind, Rudeus created a system—a construct unlike anything the gods had ever seen. He called it Kaido. A game-like system filled with the histories of fallen dimensions, worlds once destroyed by powerful beings. Those chosen by the system would relive these histories, facing trials that would grant them the power of the very entities who had nearly brought these dimensions to ruin.

But Kaido came with a price. Once chosen, the individual could only access the system through sleep or unconsciousness, reliving the trials of the past. And once awakened, the user could not leave their realm until they had saved at least one dimension—a trial that would test their very limits. The system could only be activated when the chosen one's mentality was strong enough to endure the hardships ahead.

As Bianca's realm fell, she placed her hope in Rudeus's creation. But just as the Kaido system was activated, Trigon's forces overtook Rudeus's dimension. With his work unfinished, Rudeus's voice echoed through the remaining demigods: "Though it may take long… Kaido never fails to make the right choice."

Years passed, and Trigon's realm expanded without challenge. Three of Bianca's seven dimensions were conquered , their essence absorbed into the Demon God's ever-growing dominion. Only Earth, the weakest of the realms, remained untouched. The Demon God's forces ignored it, deeming it worthless. The mortals on Earth—weak and powerless—were left to fend for themselves. Trigon's armies didn't even consider conquering them; they simply sought to destroy the Earth and move on.

Yet Earth was not as defenseless as it seemed. Ikravis, one of the demigods of Bianca's realm, had given the mortals a portion of her power—a blessing that allowed them to survive the chaos. She created a system inspired by Kaido, though not as advanced, allowing humans to awaken a power known as Hunters—warriors who gained strength through this blessing.

The system would measure their growth, but it was no match for the full might of the Demon God. Ikravis, too, had foreseen that Earth could hold the key to defeating the gods.

Griffin, born into a prestigious family of hunters, was destined for greatness. With white hair that shimmered like a beacon and a circle of light on his forehead, he was marked as special even before his birth. His family believed he was chosen by the gods to be the greatest Hunter to ever walk the Earth.

Yet, as Griffin grew older, his power never manifested. At the age of fifteen, when most hunters awakened their abilities, Griffin was still ordinary. His family began to doubt him, whispering that he was a late bloomer. But by seventeen, when the awakening age passed, Griffin was banished—cast out as a failure, forsaken by those who had once adored him. Only his mother, his younger brother, and a handful of loyal souls stood by him.

But when Griffin turned eighteen, the Kaido system chose him. His mentality, shaped by years of rejection and hardship, had finally reached the threshold needed to activate the system. The system chose him not because of his bloodline, nor his potential, but because of the trials he would face in the coming war.

The world would soon learn that even the weakest of dimension of the realms could change the fate of the gods themselves.
