Kaien stared at his tremoring hand and closed it into a fist, kicking in the 11th division barracks door and striding over to the arena reserved for one on one duels as a crowd of eleven or so came. They all knew, to the last man what this was, but none of them wanted to get in the arena for fear of the sheer aura of violence the man gave off. 

Then one of them charged into the arena, his shikai out. He raised his arms to lauch an overhead assault, only to be met with Kaien's fist in his stomach, before being lifted up by same fist, and slammed to the concrete floor, sinking into unconsciousness in a matter of seconds. Kaien knew that he was still alive, and as far as the rules went, he had just taken his place in 11th division. 

The crowd of ten stood dumbfounded, and silence reigned over the courtyard for a moment before the ten men rushed him, swords drawn. 

[i]Finally,[/i] he though. [i]Something to draw on.[/i] Reaching behind his shoulder, he placed his right hand on the green hilt of his Zanpakutō, and drew the blade slowly, letting the blade ring out. It was a beautiful sound for him, the only sound amidst the oncoming wave of victims. 

He held them off with ease, blocking, and placing no lethal wounds as if his blade was an extension of his body. The first two fell from graceful passes aimed at their Achilles' tendon, and the next man came up, coming in from the side. Kaien twisted his hip, and brought the blade around to block so that the tip was pointing at the ground. In response to the attempted attack, he used his opponent's momentum against him, slicing upward in the direction it had come to block, before sweeping his opponent's legs out from under him. A quick knee to the nose had him stay down, but alive. There was only one man left, and he had wisely chosen to use shikai. Kaien widened his stance, and raised the blade up and back so that the tsuba was level with his nose. 

The other man rushed, too frightened to think of anything else but a full frontal assault. Kaien pivoted on his feet, bringing his sword up in a v style slash across the chest that, while it did not kill, put his last opponent down. 

Kneeling, Kaien cleaned his blade and bowed in front of it, following a ritual set forth by the Samurai of the Living World, who had aptly named it Kenjutsu, "the Way of the Sword." To Kaien, it was more than a discipline, but a way of life.
