Kai was ready for the attack, ready for the jump. What he wasn't ready for was the height of the jump. He was used to fighting Geshrin, who jump a LOT lower than Yamataians. Needless to say, the tip of kiyoshi's practice sword connected easily with Kai's rather fragile nose, Basically shattering the protrusion, causing a rather large, red explosion. This left Kai grabbing at his face with one hand, and angrily brandishing his sword with the other. Blinded by pain, rage, and a bit of blood, he took a swing at his opponent, who might or might not be expecting one.
