In a world divided into three regions, every child is born with a destined Beastborne—a mystical beast that merges with them at the age of nine. The strength of one’s Beastborne defines their future, granting unique abilities and transformations that shape their destiny.

Kairo Tenma, a young warrior gifted with the Phoenix Beastborne, embarks on his journey to unlock his true potential. Alongside his closest friend, Raizen, he trains to rise through the ranks of the strongest warriors. But fate takes a cruel turn when Raizen betrays him, revealing a shocking past that changes everything.

With revenge burning in his heart and a new ranking system reshaping the world, Kairo must grow stronger, uncover the truth behind his father’s legacy, and face formidable enemies—both human and Beastborne alike.

Epic battles, rivalries, and sacrifices await as Kairo and Raizen walk separate paths, destined to clash once more.

Will Kairo’s Phoenix rise from the ashes, or will Raizen’s thirst for vengeance consume the world?

Beastborne

Kairo wiped the blood from his lip, his golden eyes locked onto the monstrous entity before him. It was nothing like the Ghostfang Alpha.

Something that knew about the Phoenix inside him.

Raizen took a step forward, lightning flickering around his blade. "Whatever this thing is, we need to end it now."

The creature chuckled, its red eyes glowing. "End me? You misunderstand."

The ground trembled beneath their feet.

Dark energy coiled around the beast's form, twisting like a living shadow.

Kairo felt a strange pull, like his body was being dragged into something unseen.

Kairo's breath caught in his throat.

One second, they were standing in the forest—

The next, they were somewhere else entirely.

A vast, endless battlefield stretched before them, the sky a swirling mix of fire and storm clouds. Golden flames danced in the distance, while streaks of lightning split the sky.

Raizen turned sharply. "What just happened?"

The beast's voice echoed around them.

"You have been brought to the Trial Grounds."

Kairo clenched his fists. "Trial for what?"

Suddenly, two figures materialized before them.

One figure was wreathed in golden fire, standing tall with crimson wings stretching from his back. His very presence radiated overwhelming power.

The other was covered in arcs of silver lightning, his eyes glowing with storm-like energy.

Raizen's grip on his sword tightened. "…Who are they?"

Kairo's breath hitched. "Firstborn?"

"The first to ever wield your flames and lightning. The ones who mastered their power and left behind a legacy."

Kairo swallowed hard. "And what do they want?"

A pillar of fire erupted behind the Phoenix-born warrior, his gaze locked onto Kairo.

A storm surged around the Lightning-born warrior, his eyes narrowing at Raizen.

It was a fight against the very origin of their power.

They might never leave this place.
