History: Koutetsu was born a rather unique oni. He lacked the usual bright colored skin of his kind, which led to him being feared in his village. His marble white skin was considered signs of a curse. In time, It became painfully aparent that he was far different, As his strength was greater than any in his village while his speed was considered godly. It was when he displayed his talent for manipulating the elements that he went from being feared, to being admired. He was aclaimed as one of four incarnations of a great demon known as Yamato no Orochi. He despised the attention however and thus, he left his village, Taking only his armor and his blades with him. It's been a very long time since then and he has been all around the world, Helping people as he went, his gentle nature compeling him to do so. In time he came to to be known far and wide as deadly and efficient hero as any foes before him fell. His fame also drew many bounties from angry crimelords and villans allike as well as treasure hunters seeking his legendary blades Muramasa and Masamune. This fame has also led to him being sought after as a teacher of the arcane arts and the art of the blade, many of which are turned down. In recent years he simply lets his feet take him where he's needed, while his blades deal justice when the time comes. This however came to be tedious and boring, thus he began to step between demensions and worlds as well, learning much and growing ever stronger in his journeys. In this Time he began to be known as "The Eternal Paradox" Due to his mastery of the blades Masamune and Muramasa and his completly contradictory elements of Lightning and Earth. Now, countless centuries and millinia later, he simply floats in the space between dimensions and realities, waiting for when he is needed.
