The World is Empty kata was one of the Thousand Years of Steel kata created by Mirumoto Uso and Kakita Kaiten. Both Kakita and Mirumoto Hojatsu were mortal men, but still mortal men who walked alongside the Kami and fought against their Dark Brother Fu Leng. Although they were not gods they learned that a even mortals could reach within to find a point of perfection; the Void. They both sought to hone their ability through training with the sword, and this kata drew out and expanded upon this inner power in a swift display of awesome skill. The focus of the kata was more intense than most and could not be maintained for long.
