An old man opens an ancient book .The ink shifts on the pages , forming vivid, moving illustration .His voice is calm yet filled with mystery . Old Man ; Long long ago before peace ever arose ,war consumed the world .A war between humans and beasts....but the true threat was neither .The reason of the great war was because of the demons , a force that twisted minds and hearts ,corrupting even the purest souls of the warriors but not all demons where evil. Among them was Zorvath a demon but a kind hearted one, one of the beasts greatest and strongest allies .A warrior who stood at the frontlines , fighting along side them .A person who believed in peace and kindness and the bonds between humans and the beasts. But Faith was cruel .One day he returned home later that night and witnesses his home burning .He ran to save his family but saw something slaughtering his family before his eyes.Everything was gone...And saw who killed his family. It was a person using the Beast power but disappeared before he could catch him.he tried until he heard something crying in the ashes of this burnt home.It was the only thing that survived in the ashes.Zorvaths faith and hopes where shattered.Anger burned within him.And then...A dark figure appeared from the shadows, it was pure evil and it extended it hand. It's voice smooth like poison. The dark figure promised him power and vengeance . In that moment of despair, Zorvath listened with burning heart of revenge.And in that moment his fate was sealed by darkness.The figure's darkness fused with him , wrapping around him,whispering, twisting and corrupting him.Until the warrior who once stood up for peace was no more. After that Zorvath was no longer himself, he destroyed homes, lands and corrupted the world with darkness. And the countdown for the Great War began. . Amidst the chaos , the mighty king of all Beast romoshikai , fought on the battlefield .But Zorvath did not strike him directly instead he vanished into the shadows and corrupted his very mind and heart.Corrupting Toyama and showing him how evil the world was and twisting things for him to believe . After that romoshikai lost control of himself , his wrath tearing the world apart, drowning it in destruction it was as if the king of good was a God of evil. .For years destruction followed . Cities fell and lands and kingdoms crumbled.The demon Zorvath become a king of demons his influence spread like wildfire while corrupting romoshikai (silver lightning) the god of beasts. The once great and kind ruler, was now consumed by darkness ,he became mindless, driven only by rage.The world suffered under his uncontrollable power. .But then , after many many years pasted by .Two warriors stood against him, wanting to restore peace.The parents of two young brothers , the parents names where Kaito Tetsunnya who was a human and Natsuko Tetsunnya who was a good demon.They knew the truth that toyama was not the true enemy but a victim , his mind and heart poisoned by Zorvaths influence.With their strength they fought against the corrupted Beast, determine to put an end to the suffering. . But even with their combined power with they're beasts, they could not stop romoshikai because he was a king a God of beasts energy.He was no ordinary beast he had become something far beyond mortal limits.Defeating him was impossible. So Kaito and his wife Natsuko made a bold decision.A choice that would change everyone's destiny.saji the youngest son who was just a newborn would become something beyond human.He would be the answer to the war , a being was both human and beast.Not a vessel , not a cage but a true fusion of both worlds.They used the last of the legendary combining crystal called jinseki.Placing it in the ancient summoning shrine.The ritual
was set and when romoshikai arrived and stepped in the shrine the binding began. . The process was agonizing saji very being was torn between two worlds,his human body unable to contain the overwhelming force of the beast power.His bones cracked and grew stronger, his skin burning in gold and his soul felt like it was splitting apart.yet , despite the pain , he did not perish but cried. He survived the fusion when it was over he was no longer just human, nor just beast.He had become
entirely new something, never seen before.His eyes once ordinary now glowed an intense blue , sharp and wolf Beast like , reflecting the untamed power within him . .katio unable to withstand the overwhelming force of the ritual perished.Natsuko before she vanished into the unknown left her final words to her elder son Terriko.Take care of ur younger brother .Terriko cried after losing his parents and knew he was left with a duty to protect his baby brother saji from everything and from those who sought to extract his power for evil .So they went back to they village called Kakuri a hidden village that no one has seen but few people knew the village .Even a map could not guide u to the village , it has no location.it truely hidden.
