At that time, there already existed a Hybrid Chimera who fought fiercely against many powerful men and monsters, gods and demons.

The Ultimate Monster, the Dragon of Destruction, and the Bringer of Demise.

The Great Chimera Black Dragon, Azi Dahaka.

Known to be the most dangerous creature of all over the old times, Azi Dahaka was feared as he wreaked havoc all over the earth at that time.

But then...

He was defeated.

Slain by a being unspoken within the legends of old, a being whose name is undiscovered in the records of the Old Age.

But after the Old Age ends, Azi Dahaka returns, this time after recovering himself after his first defeat, he returns again to scorch over the earth in the midst of his rage.

This time, he successfully defeated the New Era's mightiest creatures, for it is ironic since those born after the Old Age are all weaker than their predecessors who once fought the Dragon at his peak.

That's why for some time, he managed to rule this very Newly-born Earth.

It was all as he wanted it, until...

Those who faced him this time managed to Seal Him and Mutilated his body parts, sealing his very Soul within it to make sure he never once returned.

" That was the story of Azi Dahaka, the 'First Chimera Master'. " Yakujin explains to Shiro as she tells him

" If it wasn't because of him, despite every creature still fear and hated him over his crimes. "

" The beginning to usher in the Era of Hybrid Creatures and Chimeras will never happen. "

" For making Hybrids in the first place, were all inspired by the Dragon's combination of monstrous creatures. "

" Even amongst Mankind and Monsters, many still try to find every Relic, every body part of 'The' Chimera Master himself. "

" Including me... " Yakujin says, remembering how much of effort she had to make to claim the Relic inside the 'Black Box', hence, why she kept it safe, even using many Talismans to guard it.

" Why they all want to find it, Master Yaku? "

" Why does this 'Body Parts' have to do with the Hybrids and Chimeras? " Shiro asks.

" Because every body part holds some of the Chimera Master's very power, a power believed to able to evolve any creature who absorbs it, making them evolve into a being similar to Azi Dahaka was back then.

" Many had tried before and succeeded. "

" But not for a long time. "

" For what those foolish creatures don't know. "

" That aside from the Body Parts, Azi Dahaka's Soul still exists. "

" Manipulating those who used his power, using them as his very vessel. "

" One of the reasons why I punished you earlier, Dear Shiro. "

" For I was also checking if you're already possessed by him or not. " Yakujin says as her tail hugs Shiro as the boy is quite afraid after hearing it.

" Me? Possessed? " Shiro cowers after hearing it.
