Prologue
Once upon a time, there was a young ninja who was the most skilled assassin in Konohagakure. Spoiled, self-absorbent, and handsome, Kakashi Hatake cared not for human life. Many people wished death upon him for killing their loved ones for no reason.
One day, Kakashi was sent on a mission to kill a small-ranking crime boss who resided in a small village. He succeeded, but in the process, killed many men, women, and children in the village because they were unfortunate enough to be in his way.
Now as he was passing through the main road, the bodies of the innocent piled on either side of him, a young girl stepped into his path, a small corpse in her arm.
"Why have you killed my little brother, ninja?" She asked, tears rolling down her cheeks.
Kakashi looked at her before he merely shrugged. He was not in the mood to kill anymore. He was about to walk around her when all of a sudden she dropped her brother on the ground and crossed her arms above her head.
"Kakashi Hatake." Her eyes began to glow a mesmerizing purple. "I cast this mark upon you - thus draining your chakra till you have no more." She pointed her arms at Kakashi and he suddenly felt a burning sensation on his chest. He ripped his jacket open to see a black symbol appear on the pale skin. "That mark will spread over your body until you are completely consumed by it, sending you to hell when it has reached your red eye."
Kakashi looked at the girl, frightened a little. "The mark will consume you in ten years - but fear not - should you learn the true value of human life before that time comes, the mark shall disappear."
The girl's eyes went back to normal and she collapsed onto the ground. "Remember this, ninja." She gasped before she slumped over her brother, dead.
Kakashi, though somewhat troubled, went back to Konohagakure. He soon realized, however, that he could not generate his chakra anymore-it was blocked. He also realized that the mark on his chest was spreading a little bit everyday.
Everywhere he went he was either laughed at or scorned. Finally, after a year, he disappeared. Some say he went to a new village to start anew. Some say he joined a circus to clean the latrines. But some believe that he lives in the mountains, waiting till his time comes in loneliness.
