Within an unknown forest

In the depths of an unnamed cave

There lay a young woman, who could have been no more than 17 years of age. She was resting on a large, circular mattress, the center of which was sunk in due to her weight. The lower half of the young woman's body was covered with a blanket, although her swollen feet were sticking out from the bottom. Surrounding her were strange creatures made of snow and rock. Golems and Snowmen. The depth of the cave made it rather dark. However, it was not impossible to see, for there was a light source, small though it was.

The light seemed to come from the young woman. But upon closer inspection, it would be revealed that the source was none other than one of the two newborn children in her arms. The male child was surrounded in a cloak of bright, blue flames. And yet, the young woman and the female child did not seem perturbed by the fire at all. The female baby was sound asleep, the continuous rising and falling of her chest the only indication that she was not a stillborn. The young woman was gazing at her children, with eyes full of love and cheeks stained with tears. For she knew, as did the creatures watching over her, that her time on this earth was over. The energy required to give birth twice proved to be too much for the frail woman.

"Oh, my children. If only I was stronger, then you would not have to go through life without a mother…" she whispered to the sleeping babies.

Mere seconds after uttering this statement, two men rushed into the cave. The first, dressed in the robes of a pastor, and with a full head of white hair, was panting while desperately shoving the Snowmen and Golems aside, so as to near the young woman. The second was dressed in a rather ridiculous frilly, puffy white suit. His outfit was completed by excessively pointy shoes, a cane, and a striped top hat. He strode along after his companion, looking as if he was taking a casual stroll.

"Yuri! Yuri, why did you…?" Fujimoto Shiro trailed off, at a loss for words as he finally laid eyes on the children in the young woman's arms. More specifically, the child clad in blue flames.

"Look at my children, Shiro. Aren't they beautiful? The boy, his name is Ichika, and his baby sister is Madoka. Oh, my sweet, sweet children," Yuri said wistfully.

"Yuri… what have you done?" Fujimoto asked in muted horror.

"Why, I think the answer is simple, old friend. Young Ms. Egin here has given birth to the twins of Satan!" the oddly dressed fellow exclaimed with flair.

A moment of silence.

"Yuri… As the Paladin of the True Cross Order… I have no choice but to execute these children… " Fujimoto said quietly. Yuri's face quickly contorted with panic.

"No! I won't let anyone hurt my babies! Shiro, don't you dare touch them!" The young woman shouted, while drawing her children closer to her chest. All the loud noises and commotion had woken the babies, who now began bawling, possibly sensing the threats to their life.

"I don't want to do this, Yuri, but as Paladin, it is my duty to ensure the continued safety of Assiah. Letting the direct spawn of Satan wander about the place goes directly against that! Regardless of if their demon powers have been diluted by human blood, I must end this now, before it becomes an even bigger problem later. I have no choice…"

Fujimoto slowly pulled a six-barrel revolver from the inner pocket of his coat, flicked off the safety, cocked the hammer, and aimed. He had the gun pointed straight at the wailing flame-cloaked boy. It was impossible for someone of Fujimoto's skill to miss at this distance.

And yet, he did.

Staring at those innocent children, looking into those azure eyes, regardless of what they might do in the future, Fujimoto felt regret and shame for what he was about to do. He twitched, just a few millimeters, but it was enough to cause the bullet to imbed itself in the stone floor of the cave, rather than the small skull of the male infant.

Yuri looked as if she was about to have a heart attack, Fujimoto was staring at the smoking barrel of his gun, the twins would not stop wailing, and that strange fellow had yet to react.

"Hmm, this poses a problem. Father will be enraged if his newest children are murdered, and the Grigori will have both of us hung… What to do, what to do…? Oh! I know! How about we just make them human?" said the strange fellow, with an equally strange amount of excitement, as if this situation had no impact on him.

"Turn them hu- Mephisto, have you finally gone mad!? Even if it's you, such a thing should be impossible!"

Mephisto Pheles gave a wide grin, and took off his top hat, spinning it around so the top was facing up. The strange man took his cane, and tapped it against the side of his hat.

"Ein, Zwei, Drei!"

A long object came out of the hat, like a magic trick that cheap magicians did involving rabbits. It was a katana, with an ornate silver crossguard and a blue hilt, sheathed in an equally-blue scabbard. A green ribbon was wrapped around the top of the scabbard.

"This, my friend, is the Koma Sword, otherwise known as Kurikara. Using it, I can seal young… Ichika, was it? Well, I can seal young Ichika's demon heart within the sword, allowing him to masquerade as a human. Should the sword ever be drawn after this process, though, Ichika will have access to his powers. And should the sword ever break, he will be consumed by the blue flames, transform into a full demon, and go on a rampage until he had either killed every living thing on Assiah, or been exterminated. Leaving the fate of this realm in the hands of a newborn… It's the ultimate gamble! I'm getting shivers just thinking about it! Isn't that great?" Mephisto finished cheerfully.

A thoroughly disturbed Fujimoto sighed, and raised his gun once more. "As I was saying, it is my duty as Paladin to-"

"Shiro!" An extremely distressed Yuri shouted.

"Relax. It was a joke," Fujimoto deadpanned, stowing away his gun to reassure the distraught woman.

"Well, it wasn't funny, mister!" Yuri yelled, before she slumped back into her cushion, panting.

"Oi, oi, what's wrong, Yuri!?" Fujimoto asked, taking a panicked step forward.

"If I were to take a guess," Mephisto cut in, "I would say that she is extremely exhausted from giving birth to not one, but two children of Satan. Regardless of if little Madoka-chan hasn't seemed to inherit the blue flames, she would still be powerful due to her father's blood. Put shortly, Fujimoto-san, young Ms. Egin is dying."

There was more silence as Fujimoto fully comprehended the words if his companion. He examined Yuri, looking for the signs. And he found them. The intense paleness, making Yuri, who had always had a rather light complexion, look paper-white. Her face was gaunt- her cheeks and eyes were sunk in, and the young woman now resembled a skeleton. She was sweating quite a lot, as well, regardless of the harsh winter outside. Her breathing was coming slower and slower, and Shiro bet that if he checked her pulse, it would be the same.

"...Mephisto. Do it," Fujimoto whispered.

Mephisto's uncharacteristically somber expression quickly morphed back into his usual grin, and he took hold of Kurikara. Tapping the katana with his cane, he uttered the same three words that summoned the sword in the first place.

"Ein. Zwei. Drei!"

And with that, the cloak of blue flames surrounding Ichika fled the boy and became entrapped within the sword, where they would rest for many years.

"Shiro, I want you to promise me something." Yuri said. Fujimoto nodded in response.

"Take care of my babies, okay? And make sure they know about their heritage. Satan told me that other demons would come to test their strength against them. I want my children to be prepared, and able to defend themselves. Who knows... maybe they'll become better Exorcists than their mommy." She finished with a small smile.

Fujimoto nodded again, unable to put together words.

Yuri sighed one last time, before her eyes closed forever. The wailing of the newborn twins would be the only sound in the cave for quite some time to come.

Rewriting this story. There were only three chapters, so it won't take long. Plus, I wrote this years ago. Frankly, it sucked. Don't know how far I'll get, though, so don't get your hopes up.
