A Blue Exorcist AU Fanfiction

I don't own Blue Exorcist but I wish I am.

In a dark room with no one going in, stood in the middle was a one big glass tube with neon green water inside. It held the two demon twins, the twins was just barely a week old, floating inside the said tube. Both was in deep sleep as they face each other, they didn't even care the world around them. Both having white hair and tails that intertwine to each other, seeking comfort to each other even in their unconscious state. Both inherited their biological father, Satan's famous blue flame. Their demon heart coated in the said flames beating to keep them alive.

...

On the other side, a church stood, inside of the said church they're two figures, one sitting on a chair as she face the other person, who was standing not far away from her. "Shiro, we have to get them! I don't care what will happen, I just want my children back!" A voice came from a woman, she had dark brown long hair that extended until her lower back. She had pale skin and face, having two moles under both eyes and one on her right chin. "But Yuri, you know what was the consequences right? They're demons, not just demons, they're the sons of Satan!" Said the other person in the room to the female named Yuri Egin. The male had a gray hair, almost faded to white, he wears a rounded glasses that rested to the bridge of his nose. And a black coat that indicated that he was an exorcist.

"I don't care Shiro, I know they're demons and we.. Exorcist eliminating them but they're my kids! They're half human, they're not full fledge demons!" Yuri burst in anger, feeling range inside, she can't do anything to help her twins that was confined on the underground facility of the True Cross Academy. It's only been two weeks since she give birth to the twins and the Griggori odered all the exorcist and the Paladin to kill the said demon twins that belong to their enemy Satan.

"I know" Shiro Fujimoto sigh and pinch the bridge of his nose. He was assign to kill Yuri's children but he couldn't bring himself to do it, he look down at the sword laying at the table. The Kuoma sword, also known as Kurikara that holds a fire demon for so long. It was about to used to kill the demon twins, he sigh again. "Alright, I'll help you to bring back your kids" He said as he made his final decision to help his friend, Hearing this, A hope bloom inside her chest and Yuri smile. "Really?" Shiro nod and bring out his phone to call someone who could help them. "Who are you calling to?" Yuri ask as she look at him, confusely. "A friend that can help us getting back the twins" The Paladin said, not bothering to look at the female.

...

"So, you want my help to get back Satan's kids?" Saids a person with purple hair with curl on top of it. He had green eyes, pale skin, fangs and pointed ears and he dress like clown. All in all, he's a demon, not just a demon but one of the Eight demon kings and one of Satan sons. "Yes and I know your the only one that can help us Mephisto" Shiro said, looking at the said demon.

The demon, Mephisto luagh and eventually stop his hestical luagh and look at Shiro and Yuri. "Alright, I can help you with that" Shiro narrowed his eyes "And what are the consequences?" Mephisto luagh again "Can't I just help a friend of mine? Don't worry, there's no fair trade" He said and just a flick of his wrist, both Shiro and Yuri ingulf in a pink smoke. Once the smoke subsides, they face to face a huge glass tube.

"Now what will you do? Here is it?" The demon said as his gaze fell over to the two figures inside the tube. "And hurry up before the exorcist gets suspicious" He added.

Shiro emmedietly turn off the machine as the water inside the tube slowly draining, once done, the glass burst open. Yuri quickly took the twins in her arms, both slowly coated in flames. "Oh? There's other one, you have to seal their demon hearts if you don't want go arround walking with a babies coated in flames" Mephisto said, now, was infront of the two, looking down at the still sleeping demon twins. "Can you do that Mephisto? Seal their powers?" Shiro ask, the said person nodded his head and a grin plasted on his pale face. "Of course I can! In the Kouma sword since it's a demon slaying sword and once held a powerfull fire demon before" The clown pipe up and flick his wrist again. Suddenly one of the twins flames go through the said sword like it been sucked by a vacuum.

"Now, let settle for the other one" Mephisto said and flick his wrist for the third time and suddenly there's a puff of smoke. Infront of them was another sword that the same design as Kurikara but different color, instead of blue, it's red. Shiro look at the other sword that was now in Mephisto's hand, confusely. "Let's say, it's Kurikara's brother named Murasame. It's another type of demon sword that holds another fire demon in the past but now, you see, it's already empty" The purple head demon said as he know what was Shiro's about to ask and flick his wrist again to seal the last one's demon heart on the demon sword and handed it to Shiro.

"I seal their demon hearts and remember, don't draw the sword if you don't want to see them lighting up!" He said and grin.

"Thank you so much Mephisto-san!" Yuri finally voice out and look down at her twins that was now free of the flames, tails and pointed ears. "Off you go before the exorcist find out that Satan's brats are gone" Mephisto wave his hand, shooing them both but suddenly stop. "By the way, you can't live in Japan if you don't want to be found, here" He flick his wrist again for the fifth time and this time and a key appear infront of the Paladin. Shiro look confuse and grab the key, he was about to ask when Mephisto interrupted him "Find a door and use that then you'll be in the different house, there you can raise them. It's in America and don't worry, you'll have complete documents" Shiro nod and walk away from the demon.

Once he find a wooden door, he inserted the key and open it, he look at Yuri. "You ready for this?" He ask the woman and Yuri nod "Of course I am!" She said, detterment in her voice and they both enter the door.

As they enter, they meet a clean living room. No dust, The living room had three couches, one double and two single sit only. "I guess, this is how it will start then." Shiro hum to himself and look at Yuri and the now free flames and demonic features twins in her arms. "We have to clean them, go to the bathroom and I'll find some clean clothes for them" He added and turn around to search for clothes to the twins, Yuri instantly nod, searching for the bathroom. Luckily, she finds it and enters it. She look down at her twins who was now wide awake, wide sparkling eyes looking at their sorrounding. Shiro then appear at the doorway, carrying towels, shampoo and soap for the baby and some baby clothes.

As they start cleaning the two boys, one of them with two moles under his left eye and one mole under his chin, cried as it made contact with the water. Yuri notice that the younger had blue eyes like their biological father, She then hush the crying infant, once done she handed him on Shiro to get dry and change. Then she proceed on the older one, she look at him and saw that her firstborn also inherited the blue eyes of Satan but instead seeing a cold blue eyes she saw a beautiful blue eyes that held wonder in it, Yuri smile and once done she proceed to dry him and change.

...

Shiro and Yuri was in the living room after they done cleaning and put the twins to sleep in their crib inside the nursery room. "Mephisto put our new identity in this birth certificates, and ID's. You have a Jasmine Okumura and I have Sean Okumura, hmmm not bad" Shiro said, amused a bit on the demon king's choices of names.

"Okumura? Means we act like merraige couples now?" Yuri raised an eyebrow towards Shiro, now named as Sean. "Yes and maybe we can start calling each other as Jasmine and Sean" At that Yuri blush.
