Slowing down [solo, p, nk]

For once in his life, Kozai found himself falling. The sensation that he was about to die came over him, and he was at peace for a single brief instant until he realized that he must be crazy if he was going to let himself die from just tripping over the rooftop of his building. As he began to fall, he shot his chains out from his arm, extending it out to give the chains a bit of extra range. The chakra chains extended forth from his tenketsu, arcing toward the rooftop nearby. Latching on, they anchored him and prevented him from falling any further.
This stopped his downward motion, but with the chain's angle, he began to swing towards the building. No! He started to reel himself in, the chain becoming shorter as fast as he could will it. He looked at the side of the building getting closer to him. He wouldn't make it in time. He had to do something... something with his chakra. Gritting his teeth, he flowed his chakra around him, willing himself to slow. With just a bit more effort... suddenly, a flash appeared in front of him, as some kind of seal diagram came forth. Falling through it, he found himself slowed considerably. Was this... a new technique?
