Right guys this is my very first attempt at a fanfiction. I have really gotten in to Ao no exorcist and have been reading everyone elses fic, so I thought why not give it a go. I have had many a daydream about this anime so I decided to put it down on to paper (well...laptop) Anyways, I have an idea of where its headed, in future chapters there may be some adult content and OC's.

And Im just putting this at the start of Chapter 1, I do not own Ao no exorcist or it's characters.

Would appreciate the reviews guys so I hope you like it. xx

Rin's POV

Rin Okumura looked down at his clenched fist. His white knuckles were covered in the blood of his classmate. He shook the scarlet drops off, and as they hit the ground he advanced once more towards the boy.

"You think you can treat Yukio like that! You think it's funny? WELL?!"

Rin's blood practically boiled he was in that much of a rage. It was the third time this week that Yukio had been picked on and it was no coincidence that it was Rin's third fight this week.

Now he had a fist full of the boy's shirt and held him up to his face. His mouth twisted into a small smirk as he drew back for another swing. The boy struggled a little but when he couldn't break free, he scrunched his face, closed his eyes and braced for the fist. Got you!

However, before Rin could follow through a hand closed around his wrist.

Slowly, and without a sound, the boy he was holding opened his eyes. Even though he was still holding his shirt his attention was elsewhere. A man, who still had a hold of Rin's wrist, stood over the two of them. The boy struggled again and stumbled when Rin finally let go. He caught a glimpse of the boy sprint off, Thats right run away!

He shook off the hand that held him and, while gritting his teeth, Rin attempted to calm down as he turned towards his father. He knew this routine all too well but never truly understood it. Why was it so wrong to protect Yukio who was unable to stand up for himself?

His gaze fell onto the boy who was now halfway across the park. Even though he was only ten, Rin was used to fights like these. He wanted to protect his brother and in some way make up for his weakness. Rin knew he was strong and using his strength he often had to protect his younger brother who appeared to be lacking in that department.

The old man's piercing voice soon pulled him back out of his thoughts.

"Rin, how many times must you be told," Shiro Fujimoto almost cooed lovingly as he crouched down to be eye level with his son, "STOP BEATING PEOPLE UP!" With a sudden sweep of his hand he clipped Rin across the head.

With his face turning a fiery red and cheeks puffing up Rin yelled back, "He was bullying Yukio!"

Rin took a defiant stance with one hand on his hip and used his thumb to point towards himself, "And I was protecting him!"

Taking his turn in the conversation, Yukio poked his head out from behind his father, "Ahhhh Onii-chan, thank you for helping me! I thought he was going to hit me again!"

Rin just replied to his twin with a big toothy grin that could be read as a "no problem!"

However, Rin's mood quickly dampened as he seen the disapproving look of his father. Guilt suddenly washed over him as he looked down at his shoes. Kicking the dirt around, he waited in anticipation as he heard his father speaking up.

"Rin, this is isn't funny anymore. It was the third time this week. Please, try to control yourself, use your words more. I don't want to have to repeat myself." The old man just shook his head as he rose back up to his full height.

Rin simply nodded, "Sorry."

The tears that welled up in his eyes were hard to hold back as he was sucked deep into his thoughts. Maybe, he was a bad kid after all. Maybe, everyone was right and he was a demon child. After all, he could never be as nice, kind and placid as his brother, even when he tried. He sniffled as a few tears made their way down his cheeks. Why can't I do anything right?

Before his mood could spiral further down he could hear Yukio gasp. Rin quickly lifted his gaze and looked around, wondering what had made his brother panic. However, before he could ask what was wrong Yukio ran past him, "THE SWINGS ARE FREE!"

Rin's cheeky grin quickly returned to his face and as he whipped his face dry he bellowed, "Race you!" As he sprinted past his brother, any bad thoughts he had, vanished.

Amaimon POV

In one of the tallest trees in the park stood Amaimon. He had been perched on the highest branche for the past hour as he watched the humans enjoy the so called "wonderful day" they were having. Honestly, he couldn't understand how the sun made humans so happy, they were strange creatures and many were quite boring.

However, he had come to the park for a specific reason.

~Flash back~

"I don't see why I must watch him." Amaimon was sitting on one of the chairs that furnished Mephisto's office. He continued on, his voice almost a whine, "You are the one who is interested in him after all."

Biting down on his lemon sucker he watched as his older brother took a sip of his tea. Mephisto sighed and placed the pink, spotted cup down. Suddenly and without warning he leaped over the desk so that he was just a few inches from Amaimon's face. If he had been trying to make his young brother flinch it did not work. Ten for effort.

"Because, you are the youngest and I have things to do, like running a school and such." Mephisto straightened up and while stroking his chin he made a puckered shape with his mouth and cooed, "besides, I wouldn't be as brash as to interfere in my own bet now would I? ~That's why you'll do it for me~"

He sang the last part of his explanation, taking each word at a time.

Amaimon crossed his legs and with a sigh nodded, "As you wish brother." Placing another sucker into his mouth, strawberry, he closed his eyes and hoped that Rin Okumura was not boring.

~end flashback~

Sighing, Amaimon turned his beaded eyes back to his target. The child was now on the swings, laughing and giggling as he did his best to get as high as possible.

Even though the child led a normal life he wasn't as bland as Amaimon anticipated. The child fought, a lot. Any time his brother was threatened he attacked. Whenever somebody was being hurt he lunged. Where ever he was the child managed to cause a scene. It had been constant for the three months he had been watching him.

It had also amused Amaimon slightly when humans would call the child a demon. How ironic, little did they know, and from his observation it appeared that the child did not know either. Pity, he had such potential. If he was this angry and aggressive being reared as a human what would of he been like in Gehenna?

That thought was not boring. Maybe Amaimon should bring him back? He nodded, father would certainly appreciate that. He doubt brother would care either, in fact it would amuse him. He lived for entertainment after all, and what was more entertaining then turning the son of Satan against his so called family.

It was decided. Amaimon leaped from the tree and landed at the base of its neighbor. He was well hidden in the shadow and now he just had to wait.

Rin's POV

Higher! Higher! Rin laughed as the competition between him and his brother grew. Who could get the highest, who could reach the sky? Rin wasn't good at much compared to his brother but one thing he was good at was messing around.

His legs swung back and forward, back and forward, in time with the swings momentum and when the time was right he jumped. He could feel the wind rushing around him, like it was parting just to let him through. It felt glorious, in that moment he was a king, but just as quickly as the feeling of euphoria came Rin's little world came crashing down as the ground came rushing toward him. With a yelp he managed to get his feet under him just before he hit the ground.

A loud thud, and a clumsy stumble followed as Rin landed. "TADDDDA."

Yukio yelled in support and the old man laughed at Rin's rubbish dismount. He was about to argue that it wasn't funny when he realized nature was calling.

Giving a brief explanation to his dad Rin ran off to use the public toilets that were nestled in the trees.

When he was done his business, he left the small structure with a scowl. It has been filthy and the quicker he could leave the better. However, just before he ran back to his brother he heard a whistle. Looking around, he was unable to find the source. Strange, I could have sworn… There it was again, another whistle.

It was coming from behind the building and being the daredevil that he was Rin decided to investigate.

He walked around the back to where he thought he heard the noise but there had been nothing there. With a shrug he went to turn back but he never got the chance as a hand clamped down on his hands and he was pulled deeper into the trees.

His body went rigid as he felt a cold breath beside his ear, "Hello, Otouto."
