Set in the Naruto universe. The main character is the same age as Itachi and the ending occurs a few months before the Uchiha massacre.

-----------------------------

The child was born with unnatural ease, not making a sound or movement to the point that his parents worried that he had been born stillborn, until they had nearly had a heart attack at the sight of piercing purple ringed eyes staring at them from the child that lay in his mothers arms. The doctors had exchanged meaningful looks, before one of them had slipped away seemingly unnoticed by anyone else in the room, but unknown to them, a pair of doleful rinnegan eyes had followed their progress.

The mother and father had been rejoicing, a peaceful picture as they spoke to their child, until the peace was ripped apart by the entrance of a masked anbu and Shimura Danzo, who sent a look towards the anbu. The mother clutched her child closer to her chest whilst her father moved in front of his family protectively, only for him to collapse to the floor, a kunai sticking through the back of his neck, piercing through his brain, his mouth agape as his face was frozen in an expression of surprise. The mother began to scream, tears forming on her cheeks moments before the child was pried from her cold, unmoving arms, blood leaking from the gaping wound on her neck as she collapsed to the floor.

The child cried for the first time that night, as he squirmed in the arms of the man who had his parents blood on their hands.

It was also the last time he saw the outside world for a long time.

-------------

The child was given the name Shou.

All Shou had known was the dark, damp confines of his cell and the anbu that stood guard there. The loneliness was suffocating, it drove him to desperation for companionship, for the freedom he had never known. Silence was his only companion in the darkness, his ears deafened by the everlasting emptiness that seemed to fill his world.

But he didn't mind. For it was all he had known.

------------------------

The first time a guard had come for him, he had been excited. He had hoped that they would finally let him go outside as he jumped up, running towards the bars with a smile on his face, his voice slightly croaky due to lack of use:

"Hello!"

He got no reply, the anbu merely pushed open the door and dragged him outside by his wrist, ignoring the slight grunt of protest Shou had let out at the bruising grip used as he followed the man. He was dragged to a room with an aged man carrying a walking stick, the bright disposition of the room causing him to squint, unused to the light. His smile soon dissapeared, replaced with horror as a cutting pain bloomed through his head as the anbu threw him against the wall, before proceeding to attack him in what was refered to as 'training'. He returned to the cell hours later covered in bruises with several broken bones after Danzo had proclaimed him 'weak'. From that day forth he would be subjected to training every day, returning to the darkness injured.

And he hated it.

-----------------------------

The first time someone entered his cell that wasn't an anbu was the day he met the sharingan. He had been wary the moment Danzo had entered the cell with a male with black hair and equally black eyes, shuffling into the corner as far as he could in an attempt to put as much distance between him and them as possible. The black haired male had shared a glance with Danzo, before nodding and advancing on the boy that curled up in a corner trembling, his eyes turning from black to red. He then proceeded to torture the boy. They ignored the boys screams, his cries, his pleas for them to stop. They had ignored him as they tortured him.

And he hated them. He hated them all.

-------------------------------

The first time Shou killed, he was fascinated by how easy it was. He relished in the way the person had choked on their own blood gurgling from the weapon he had stabbed through their throat, awed at the beauty of the liquid that flooded from the body that lay cold and dead in front of him now.

And He loved it. He loved the feeling of cutting someones life to an end with your own hands.

------------------------------------------

Shou grew with the slow passing of time, torture a daily part of his routine. He grew stronger, he grew angrier, he grew colder with every passing day, his eyes cold and hard whenever anyone approached him. Yet, when alone, his eyes lit up with a disturbing light as he sang to himself in the corner of his cell, his eyes wide as he swayed from side to side to the tune that only he new. He refused to obey orders, denying Danzo's orders without hesitation.

The only thing he would do willingly was kill. Give him a weapon and he would use it without hesitation, a gleeful smile on his face as he cut somebodies life short.

And the desire to see blood grew stronger each day.

-------------------------------------------

The first time Shou met the hokage, he was disgusted. The man saw nothing wrong and refused to do anything for him, claiming that what Shou stated about Danzo were merely outrageous lies out of his blind trust in the man who was apparently his friend. Shou soon garnered that humans were a stupid, naive breed that were corrupt, evil and blind.

And he hated them all.

-------------------------------------------

Odd laughter shattered the silence of the darkness, causing the guards to flinch. It sounded disturbed- unnatural as it rang through the silence. The laughter came from a boy who sat in the cell, his arms splayed beside him as he laughed at something unknown to anyone but him. They were uncomfortable around him, well aware that the boy had snapped and would probably jump at the chance to kill them.

Only they didn't know exactly how much that desire grew every passing moment.

--------------------------------------------

The sound of screaming ripped through the darkness, blood splattering across the walls as the guards skull was crushed, his eyes bulging as his brains were layed open for al the world to see. The boy smiled at the sight, his hand coming up above his head as his expression grew more manic as he stared at the beauiful red colour that painted his skin.

He loved it.

And he wanted to see more.

---------------------------------------------

The people who remained in the building were tense when the sound of screaming cut through the silence, a sense of danger filling them as they prepared for attack. The two guarding the door were the next to die, the only warning they had was the sound of slightly manic laughter filling the air around them moments before their heads flew from their body, the boy landing soundlessly between their body, removing their weapons with his smile never faltering. He soon moved on, making his way through everyone in the building.

The people to go next were in the training room. One of them suddenly fell to the floor as a senbon lodged itself into their brain through the soft part of their skull, killing them immedietley. The other members began to panic before they found themselves dropping in moments as they were all killed one by one.

And he loved it. He loved the smell of death that filled the building as he killed of it's inhabitants.

-------------------------

Unfortunatley, he was unable to kill Danzo when he lunged at him, hacking with various weapons as he laughed unnervingly, for reinforcements began to make their way there, but he still managed to destroy one of the mans eyes, which gave him great satisfaction at seeing the beautiful red produced from the man he hated, before he felt a sprouting pain in his back, causing him to cock his head in confusion as he removed a blood stained kunai from his back, his grin widening before he dissapeared, leaving a trail of blood and his words echoing through the minds of those present, a haunting omen to them:

"It's a shame humanity is not as beautiful as their blood."

This started as a oneshot, but it seemed to be a good idea and is now a story after much consultation with Tigzy435 and JamesZoo.
