Prologue

A young woman laid inside a cave, on the ground with two babies in her arms. The woman was indeed Yuri Okumura, whom was being hunted down and arranged to be killed as well as any children she would have. So, she had come there to hide away.

Yuri could hear someone enter the cave, a man whom she seemed to know. The man could easily described as clown like in appearance with his pointy shoes and his fancy white suit and top hat. His pink colored umbrella swinging about. She couldn't help but smile weakly at him.

"My, my, don't you look so...exhausted, that pregnancy must have really done it's magic," The Demon snickers, already amusing himself though he was quite serious. "I've never seen anyone so weak as you are now."

"Mephisto, I am so glad it is you," Yuri says weakly as she smiles, "I was hoping you would come and not my own father. Here, these are my sons.."

Mephisto looks at her with amusement but did seem interested in the children, seeing that one of them was surrounded in blue flames and the other was not. It seemed only one of them inherited Satan's power.

"This one here, is Rin," Yuri explains, referring to the one engulfed in blue flames, "and the other is Yukio.."

"I see...so one must have been too weak to inherit the flames, leaving only one of them to claim them. However, you do know why I am actually here, don't you," Mephisto replies with a grin, "I'm under strict orders to execute those spawns."

This makes Yuri frown but she had already known this but she had no other help. If anyone could understand her, it would be a Demon King, right? Even if she were to die, she wanted her children to live on, they needed to live.

"I know why you are here, Sir Pheles, but please hear me out," She pleads and looks down at her children, "You may be an exorcist but you're also a demon, I need your help. I know this is a lot to ask of you but let them live. They don't have to be what my father thinks they will be. They can be raised under good care and since I won't be able to provide that..."

She sighs and stays quiet for a moment, now looking back up at the Demon King.

"There are two people I trust with my children, see you and Shiro are the only ones I trust not to kill them. Please, would you help me? Give them a chance."

The demon thinks about request. Really he could careless about sparing those children. However, the more he thought, the more benefit he could get from keeping them alive. That in which would make his 'playground' so much funner.

"You're asking me to take care of two children? I am hardly a father figure," he sighs and pretends to be dramatic while glancing down at Rin. "However, I take this as a challenge but know this, I have one deal to offer."

Yuri raises an eyebrow. She didn't have much time, but she would listen to him. She nods and sighs.

"I'll only be able to take care of one child, the one in flames, it is best that I handle him rather than Shrio...However, know that I can't control what he will choose." Mephisto smirks. "They will live but what follows this will be up to them. However, my one thing is...It is best that Fujimoto isn't informed that there were two because he will certainly go after Rin."

The dying woman didn't completely approve of her children being separated but if it meant that they would live, what else could she do. She takes a small breath and nods.

"I agree, just please...make sure my children are taken care of."

Mephisto grins and replies with a simple nod. Oh he would make sure of that alright. He then reaches for Rin and held him in his arms. This child would definitely make things more fun for the Demon King. The small child seemed to be comfortable in his arms and gurgled. He says nothing as he heads out.

It wasn't too long after Mephisto had left that Shiro arrived. He spoke with her for a while before taking Yukio, knowing nothing of the other child.

|This one I have done far less work on but I promise it will be done at a decent pace. I've kind of always had the idea running in my head as to what would happen with the twins being raised separate. I hope you all at least like it? I try my best? Chapter One I am still working on so just have this for now? Thanks for you patience!|
