Shinro has a very unique personality. The most noticeable of his personality traits is his child like attitude. Tho sometimes annoying this way of acting is a kind of "right of passage" for him, if he doesn't feel he can trust you with his true self then he wont trust you at all. This in its self makes it hard to get close to him. When he is meeting people for the first time or in a general setting ,like a shopping center, he tends to be withdrawn. Keeping his intentions and thoughts to himself and not making very much verbal conversation. However if you are able to melt that hard extireor you would find a kind, loving and energetic person.

 However you should not be fooled by this infantile demeanor, for under the surface lies a cold hearted warrior. In battle he seems like a completely different person. Putting all jokes and games aside he takes every battle seriously. He has been known to train so hard that he has actually blacked out from exhaustion on more then one occasion.

At a young age Sin developed a liking for childrens toys. Its nothing too off the wall, but a gift of a toy seems to bring more light to his eyes then that of money or tools. This probably stems from a yearning to return to the times that his mother would get him such toys. This in itself stems off into another of his favorite things: killing members of the Uchiha clan. Those responsible for the death of his parents and older brother where missing Nin from the Uchiha clan. Taking the life of an Uchiha would be like a toddler let loose on a factory of free candy. Tho this is only speculations seeings as he has never so much as seen another Uchiha, let alone taken the life of one.  

On a more happy note is Shinro's like of fuzzy things. If its fuzzy and breaths he will love it. If its fuzzy and stuffed he will love it. This as well stems from a lack of motherly love during the developmental stages. Sins final like his friends. Making them, playing with them, crying with them and for them. It doesn't matter what you have done, If he trusts you and considers you his friend then that's how it will be.

Due to having bitten down on a rock while wearing a rough wool sweater, Shinro has developed a distaste for the rougher textures. The feeling of bark on bare skin ,for instance, would make his skin crawl. Another skin crawler for Sin is his mild dislike for being annoyed. You could not IMAGINE the annoyance caused by being annoyed. Needless to say it wouldn't be too difficult to piss this little guy off if one was so inclined. More so on the annoyances list is pain. Due to the unspeakable event forced on him that fateful night he has developed a serious contempt for pain. Those it has not grown so far as to become a fear, pain is one thing that ,given enough, would break this child. And of course how doe one dislike pain without the dislike of fearing pain. Yes just as he hates pain he hates the very thought of pain. This has gotten to the point of fear becoming an agitator.

At the age of 3 Sin had to witness the brutal murdering of both his parents and older brother. He also had to endure a trauma that to this day he has never spoken of. That day changed him. It is these events that drives him to never loose a fight. It is the driving force behind his jutsu. Its is his very reason for living. You see the Missing Nin that killed his family belonged to a specific group. A clan known for their prowess on and off the battle field. They where Uchiha, and every day he has trained to become strong enough to take down those that killed his family. His lust for blood ,however, will not be slated by the deaths of a mere 2 Uchiha. No, for his anger and putrid hatred to be drowned from this world ALL uchiha must die!

Spiders, the undead and immortality. These are the things that drive to the heart of fear. Spiders have always been a "thing" for sin. He has never been able to stand next to a spider for more then a few seconds without flipping out. He recalls quite clearly that ,before the demise of his family, he had once had a spider crawl up his pant leg before biting him and landing him in the hospital. It was said that if the boy hadn't lacked potty training he would have surly died. The fear of the undead and the fear of those who are immortal stem from the same dark place as his hatred for the uchiha. If immortality did exist then would the uchiha he hunted become just that? This thought alone could fill a day with dread for Shinro. But the thought of them becoming the undead, the inability to die due to already being dead. How do you kill something that has been already? And all these fears caused by two lone Missing Nin. The death of his family left Sin with quite a few scars, and fears.

Ranton is an advanced nature Kekkai Genkai that combines the Raiton and Suiton elements into a single powerful element. Ranton can manifest in one of two forms. The first is as beams of energy that can flow like water and be manipulated with high precision. These beams are high speed, heavy impact techniques which can either be piercing in nature or explode upon contact with the force of roughly 5 normal explosive tags. The main weakness of this form is that the beams must flow from their origin point on the users body and if that flow or body part is interrupted they can be stopped prematurely. The second manifestation of Ranton is in the form of dark thunder clouds surging with lightning. These clouds lack the direct attack power of the previously mentioned form, however this is balanced by the severe increase in versatility. These clouds can limit enemy movement, serve as a powerful defense, and even provide visual cover.

The Isamu clan was not an accident. It's conception was planned by two shinobi families whom were renowned for their abilities with both raiton and suiton respectively. It was long ago when the first Kekkai Genkai were beginning to appear and the arrival of these new powerful techniques made both families question their superiority. In the interest of mutual benefit they joined their clans together and began interbreeding their sons and daughters with the hopes of creating a new Kekkai Genkai. These hopes bore fruit in 9 generations with the birth of the first child capable of using Ranton.
With the appearance of this new style they moved to the then newly formed Bofuugakure and pledged loyalty, in exchange for giving them a home. Life was good however it was not fulfilling for the clan as there was little use for powerful shinobi when all the village leader was interested in was building temples. For a long time they simply trained to master the arts of swordsmanship and ninjutsu waiting for a time when they would be needed . Thus a more aggressive Kage came, the Isamu could not help but find joy as the new leader expanded territories producing a need for capable fighting shinobi. The Isamu proved their worth by assisting in quelling various battles, domestic and foreign.

Shinro's past is nothing short of a horror story. In the beginning everything was fine. He was born healthy and happy. The first 2 years of his life went by uneventful, he reached his normal stepping stones like his first steps and first words. At 3 years old tho, is when the first of the hardships begin. See normally one would be potty trained by about 2 years, but at 3 Shinro had yet to comply with his parents pushing towards the ridding of diapers. Sin ,for what ever reason, refused to take on this training. One day after his mother had chastised him during a change, he ran away. He wasn't gone long before his father, who had no idea the circumstances of his leaving, stumbled upon him. Sin had been picking at the bark of a tree tears in his eyes when a rather aggressive spider had crawled up his leg and bit him. The pain had been so intense that he screamed. This scream traveled a small distance before falling on his fathers ears. Immediately his father dropped the groceries he had gone to collect and ran for the sound of his son. When the father came across sin his heart fluttered. The boy was lying on the ground his thigh having swollen to the point that it was now straining against the leg of what used to be baggy shorts. Without any other hesitation he lifted his son and ran to the village hospital. A short surgery later and sin was back to being the happy little toddler he was. One thing he will never forget is the smile that crossed his face when the doctors told his mother that his diaper had saved his life.

 Within a year Shinro finally gave into his mother pleas and quite quickly transferred from diaper to potty. At this point he and his brother became very close, almost to the point of inseparability. They spent every day together laughing and playing with friends. By now Shinro is 4 and his brother 6. At 6 it is typical for a child to enter the ninja academy. This was not the path his brother took. One morning the older brother ,Liam, had been sitting at the kitchen table when his mother dropped a form on the table in front of him. Liam picked it up and ,without a word, stood from the table and left the room, dropping the form in the trash as he went out. Sin had taken off after him before their mother had even taken a step. He followed his brother to the river that they often hung out at, but Liam just continued past it. Sin had to stop before crossing the river out of fear of his mothers wrath. He waited there for over 3 hours before his brother came back. When Liam did return however he just walked right past Sin not even glancing at him. This was the beginning of the end.

Years went by and Liam became more and more distant to his brother. Mother and father had many talks with him some short and quite others long and loud.  Shinro would wonder now and again about what caused his brother to become so distant. By the time Sin was 6, all question of his brother where pushed aside as he began his time at the ninja academy.  Every day he would wake and dress for school. At first Liam wold walk Sin to school, tho it would be a silent walk no matter how much Sin tried to start up a conversation.  Then one day about a year after sin had started at the academy, Liam took off. He had packed his bags ignoring mother and fathers question on where he was going or why he was leaving. Hell father even tried to stop Liam, but he just dodged around him. He was gone for a little over 8 months before he returned, just in time for Sins 9th birthday.  You would think that would have been a joyous day, and at first it was. However, On that day Sin went out to his favorite spot at the river. After seeing 2 suspicious men he went home. Only to find his mother dead and his brother and father hostage. Tho he doesn't remember much of what happened after that he does know that the 2 people that killed his family where Uchiha. This is why now, at age 14, Shinro Hishami has forged his will to become a great enough ninja to end the Uchiha Clan!

The sun shone down upon the land, its brilliant light creating greener colors and brighter moods. Clouds dotted the sky turning the ground into a patch work of light and dark as they lazily floated by. A light breeze swayed the branches of the tress gracefully. They seemed to dance with one another as the wind gently  pushed them to and fro.  Beneath one of those very trees sat a boy of about 9. His shoulder length hair shining a  bright shade of silver in the mid afternoon light. The breeze played in his hair making it sway, almost as if to the same tempo as the trees. The boys brilliant blue eyes looked distant and full of thought. Suddenly his eyes snap back to reality, his daydream interrupted by a black dot in the sky. As he watched that little black dot grew larger and larger. Slowly Sin rose to his feet, his baggy cargo shorts and plain grey t-shirt moving freely in the breeze as the where freed from between him and the tree. He tilted his head to the side and focused on the incoming object only to flip back moments before a Kuni ripped through the space he had been standing in.

 'I don't know who this is but they don't seem very friendly' the boy thought to himself as he launched from the ground and into a tree adjacent the one he had been resting on. He sat there motionless and hardly breathing as he awaited the hostile stranger. It didn't take long before the black shape hit the ground creating a thin cloud of dust. The boy watched from his place in the tree as the man rose. Being a student at the academy sin recognized the movements of a trained shinobi, as well as the lack of headband. 'Could this person be a rouge Nin' he thought to himself, his breath catching in his throughout, but that thought was interrupted by a second figure landing next to the first. Without a word the two men headed deeper into the forest. Fear gripped at Shinro's heart. The two men had headed directly towards his home. It was as if their intentions had been to go there the whole time. "NO!" jumping from the tree he ran, picking up the abandoned kuni as he did. His legs pushed hard on the ground as he ran full force through the all too familiar surroundings. Ether because of being distracted, or maybe just a keen disinterest in a child, nether of the two men reacted as he bolted past making it into the house moments before the two reached the edge of the property.

 As he slammed through the door he stopped. The sight before him was gruesome: his mother lay dead on the floor, a pool of blood surrounding her lifeless body. His father was next to her holding Shinro's older brother by 2 years, fear burning in his eyes. Fear and anger both faught a tremendous war within the boy. His anger for the pain of his family trying to force him to fight, to protect the ones he loved. However fear held him fast, demanding that he turn and run. However something occured to him at just that moment: there where two other people already in the room. Looking closer Sins heart filled with dread. Turning he glanced behind him only to have the heart wrenching realization burn through him wholly. The two people that he had seen approaching the house where gone, instead they both sat eyes fixed on the newcomer, from the couch. Turning back Sin fell to his knees. Defeat filling his mouth as tears welled up in his eyes. The moment the boy turned back he realized this defeat. It was the eyes of the two murderous intruders. A black ink like spiraling design over the solid color of blood. The illusion of others when none where present. These where Uchiha, members of a clan whos visual prowess was only equaled by their mastery of genjutsu.

 The two Uchiha men rose the first taking a small blade from his belt and slowly advancing on Sin.  The other lifted the younger brother from the arms of the father kicking the father as he tried to pull the boy from his grip. Crimson red rained down on the older man as the struggling boy suddenly went limp. A scream lit the air and another life was lost. The father had rose to fight the man who had killed his sun only to fall back to the ground, his life ended by genjutsu. Sin looked back to the man who had approached him and his world ended. The mans belt had been removed and a sick grin adorned his face. Blackness enveloped the boy as his mind worked to rid him of the memories that would forever haunt him.
