A long time ago, the name Arashi was feared and respected in the land of Konoha. Arashi shinobi were famed across the land for their skills in stealth and ambush. When they struck, they were a storm of flashing blades, so fast and deadly that their enemies rarely had time to even scream before they lay in pieces on the ground. The Arashi possessed a powerful technique that allowed them to control the flight of their shuriken, and it was said that not even the fastest shinobi could evade the shuriken of an Arashi jounin.
However, these powers came with a price. The Arashi, true to their storm moniker, possessed great power. However, if left unchecked, this power could rage out of control, and there was no telling what an Arashi would do if this happened. So, among the Arashi there was an unspoken rule, that not even the leaders of the clan dared break: All Arashi must have a focus, or they will spin out of control into destruction.
For a thousand years this rule was followed, until one tragic day, it was broken. An Arashi shinobi, his name since stricken from all written history, lost his focus. In years prior, the quality of Arashi shinobi had begun to diminish. It was believed that this shinobi would be different, but it was not to be. He was strong, indeed, but in his focus, he fell short. In search of power he could not obtain, he betrayed the Leaf Village. His brother and sister followed him, and together they brought great sorrow and pain upon the Land of Fire. Eventually, the Anbu tracked down and eliminated them, but not before the name Arashi became synonymous with failure and treason among shinobi.
In an attempt to recover their last shreds of acceptance, the son of the traitor refused to become shinobi, instead becoming a trader and merchant. His son and his son followed this path, and eventually all the things that had given the Arashi power were forgotten. They were nothing but traders, though they still carried the stain of the traitor in the eyes of all Konoha, and since the shinobi blood still ran through them, they quickly garnered a reputation for trickery, shiftiness, and greed. Since then, no Arashi has walked the path of shinobi. However, 8 years ago, a child was born. This child was different from all others before him. He didn't know it, but he would eventually become the catalyst by which the ancient honor of the Arashi would be reclaimed…
