Takeru shivered as the wind picked up and sent a fresh cloud of snow across his skin, covered now by a layer of thick white fur. Behind him four tails of chakra floated lazily in the air and bubbles of energy oozed over his body, his arms were gripping the side of a cliff and his fingers burned as the sharp edges of the glacier cut into his hand. The hachibi seemed to like the endless frozen plains of Korigakure and took an odd relish at seeing Takeru struggle with the cold, he wasn't used to the ice and snow being from Sakyugakure and the hachibi's insistence that he remain unclothed has starting to irritate him. The cursed bear had decided that a simple mental fight was much too strenuous and bothersome when it came to Takeru trying to wrestle more power from the beats and instead had given him a series of tasks which he had to complete. The first of these tasks was sleeping for at least eighteen hours a day and in the six hours he was awake eating an endless stream of food, this meant that much of Takeru's time was spent unconscious or hunting food across the barren wastes. In the little time he had between this was when he tried to perform the bijuu's outrageous tasks. "Shirokuma this task is another kind of cruelty, whats worse is i actually think i'm hungry again you're damned habits are rubbing off on me." Inside his mind Takeru heard the great bear chuckle, an odd sound half way between an earthquake and a million bees buzzing. "As it should be cub! And whoever heard of a jinchuuriki wielding my power if they can't climb with just their paws!" Takeru reached up with his arm once more and pulled himself up the cliff a handspan more, below him dangled two boulders the size of a small building which were tied to his legs. "Don't you think the boulders were a bit much?" The only response Takeru revived was a loud snore as his bijuu fell asleep once more, the creature spent almost every moment of its life asleep or eating and grew incredibly vexed when it was disturbed during either. After another twenty minutes he finally pulled himself over the edge of the cliff, a red trail of blood stretching up its icy face where he had cut his hands open. The Hachibi yawned inside him and Takeru felt a wave of approval rush from the bear. "A sizeable effort there cub, i half expected you to give up, my last jinchuuriki didn't have boulders tied to his legs and he still couldn't do this!" Takeru remained silent as he untied the boulders and strode back to the shelter to eat and sleep.
He decided that the hachibi must be trying to kill him, he wasn't a young man and and despite the added strength of the bijuu cloak he just wasn't made to do these sorts of things. He took a sharp breath and tried to stop himself from shivering as another wave of water crashed over his head. He was floating bare in the sea, desperately trying to keep a constant flow of the Hachibi's chakra pumping across his skin so he didn't freeze to death, the hachibi had made him carve a hole in the ice and told him to go 'fishing', which basically meant jumping into the water and waiting for something to grab hold of him. Soon enough a large shark had tried taking a chunk out of his leg and he had had to struggle to reach the surface in time to breath. As part of the test the sadistic bear had disallowed him from using any of his jutsu, a fact which was particularly annoying to him. Suddenly he was yanked underwater once more and came face to face with a large killer whale, he drew back his arm and struck it directly in the face, pieces of scattered skullbone mixed in with blood as the water become a thrashing mess of flesh and ice. Takeru kicked his legs and burst out into the air once more. Only three more hours to go.
Takeru stood against the wind, his muscled chest bare to the elements as the air screamed around him. He felt no cold, no pain from the wind's bite, he was past that now. There was no sign of the bijuu's cloak, he had no need of it to withstand the cold anymore, the endless weeks of training had given him such a tolerance for the extreme weather of Korigakure. "You think you're rather clever don't you cub?". Takeru snorted, his frozen mustache blowing out against the wind. "I think you are a fool Shirokuma, to give your power to me so easily, without a fight.". There was silence from the great polar bear, after some time he answered in a deep voice. "You already managed to seal me cub, its not as if i can break out of this blasted prison easily. Besides its nice in here, its warm and i have a effortless supply of food thanks to you. Giving you my power keeps that and besides ive come to like you somewhat, you're almost as grizzled as i am." Takeru nodded and turned back to his shelter, he took a few steps before cracking a small smile and letting forth the hachibi's chakra, 7 tails floated behind him.
5th, 6th, 7th tail mastered.
