Living in the Bloody Mist was far from easy. Training was brutal, and most didn't survive. Half alone being eliminated just for the survivors to graduate as genin. Rashiku grew up in this life, with the only difference being that his own clan's fellow genin managed to survive the tests somewhat more often than other clans. His own test taught Rashiku just how quickly battles could go. A battle with a fellow student that specialized in spiked earth jutsu. It was difficult, close, but lasted less than ten seconds. The opening burst forth with a volley of spikes made from the ground. Rashiku managed to parry most of them while running in, but had two of the smaller ones pierced into his shoulder. His opponent tried to bring forth another volley, but Rashiku reached him before he could, slashing his leg. The boy dropped to his knee, keeping his hand seal and completing it, making another spike raise straight out of the ground to spear Rashiku. That would have been it, but his blade was already swinging again downwards. As the spike began to pierce into Rashiku's thigh, his Blade cleaved down into the other boy's skull, ending the duel instantly with the spike losing form. Rashiku limped away, lucky that he didn't have permanent damage to his leg.
Being a genin of the Mist did not last long. Barely a month after his graduation, Kirigakure sent its armed forces to eliminate all clans that possessed Kekkai Genkai. The fires across the village and the outskirts lit the rainy night, while blood stained the soil. Before the Karata could gather their members to escape, explosions rocked the compound. Tags, Bombs, and fire jutsu erupted through the walls, with the Mist forces storming in right after. Even with multiple members of the clan being Jounin, the sheer number of enemies soon turned the scene into a gore-strewn slaughter. Rashiku only survived after his father jumped into multiple kunai laced with tags that had been thrown at the boy. "Run..." With a final look to his son, Ransu tackled the thrower and pressed them both into the back wall, exploding and creating an opening. The hardest part was going through the hole in the wall, covered in blood and pieces of his father, but with the other ways all leading to more screams of battle and death, the boy ran out and escaped into the night.
For the entire night, Rashiku ran, avoiding the armies as he tried to reach the border. Using his chakra sensing abilities to stay away from any other signatures. As he reached the forest border, he couldn't keep his sensing up any further, his chakra exhausted. And moments after that, a group of shinobi dropped down infront of him, weapons at the ready. The boy attempted to fight them, but he was defeated very quickly and knocked unconscious. Upon awakening, he found himself bound to a tree, with four people infront of him. "He's awake..." Getting an easier look, he could see that their uniforms were not of the Kirigakure army. It became clear that they were scouts of another group as they questioned him, asking what had happened in Kirigakure that the army had mobilized against its citizens. Truthfully he didn't know much, but he saw no reason to lie at this point, and told him of the attack on his clan, and others from what he could see. Certain clans were targeted, though as to why, he was unsure.
He fully expected to be killed by these scouts, once they had what they wished to know. But instead, the leader of them asked if he would be going back to the village. Rashiku adamantly said no, that he would probably try to hide elsewhere, never to return. At hearing that, the scout group discussed among themselves, before offering him sanctuary within the Leaf Village instead. For a moment his first instinct was to decline, with Konoha having been labeled as his enemy, but the thought soon turned around. Kirigakure was his enemy now, who destroyed his clan and family. And Konoha was their most hated enemy. The boy nodded and agreed, telling them that he'd join Konoha and their shinobi force.
