Only a few seconds. Just a few seconds that was in-between Kaizen and Colby. Those few seconds was all that Kai needed to kill Colby, but alas he didn't get the job done as the space between the two proved to be on Colby's side. The twirling of the son of Daaku wasn't met without a problem for Kai as black lightning formed, and struck kai on the left shin. Hurt as he was, Kai couldn't let it bother him. The pain would be met with resistance as it kept acting up, but Kai just had to push through it. He had landed on the ground about several meters away from Colby, but this wouldn't be without resistance, like with his shin. Colby had formed a dragon that looked to be formed out of wind and magical energy. This meant that Kai, even at his distance, would be met with heavy yet light strikes of wind at him. Kai just embraced it as he held Shokukoma in front of him to take most of the strikes, but damage had been done.
"Not bad kid." As much pain as he was in, Kaizen was quite impressed with Colby. There was a certain aspect of this kid that gave Kaizen the feeling of his inner-Kenpachi to come out more and more. This would not be good for Colby as Kaizen enters a bit of a rage mode when he's in his Kenpachi zone. As he did enter such a mindset, Kaizen had already returned to his previous place. At the time he did that, he saw Colby...no, he noticed Colby call out to him in what could be described as a raging frenzy or something of the like. What Kai didn't anticipate was that the chanting of Raikoho would begin. Instantly, Kaizen prepared to block it, but there was something else he wasn't anticipating.
"Shit, this is gonna be bad." Kai instantly raised Shokukoma."Let's do this, my friend." Kaizen said as his Shokukoma began to pulsate which at the same moment gathered reishi around itself. Kai would go downward, rotating his body in all kinda of swirling and gliding motions. Shokukoma in every swirl and gliding motion would be at the opposite end of the Raikoho slash. Kaizen knew he would have to give a little to receive a lot. So, with that very mindset dug deep into his mind, Kaizen would sacrifice a little of his own health to get in close to Colby.
"Jisoku Korosu!" Kaizen called out.
Instantly, Kaizen's entire body glowed with a radiant silver and pink aura, and he vanished. Actually, he didn't really vanish, but his speed was amplified so much that he was traveling near light speeds, but even still, there was going to be tough times for Kai as he would aim to go in close to Colby. Using his Lunar Walk constantly, Kaizen was struck on every point of the body, but only flesh wounds. His speed, and constant slashing of overhead, and underhand; vertical, and horizontal, and just any type of slashing motion would bounce off Shokukoma. Kaizen was getting a bit too slashing-happy with this. The one positive thing from all of the slashing is that with each one, Kaizen made his way closer to Colby. It had gotten to the point where just a few series of seven strikes later that Kaizen had reached to the point where he could go down the middle to get to Colby. However, Colby was keeping his defensive and offense up. Kai would get struck by another side-stream of the Raikoho on his same shin, and the pain soon became intense.
"ARRRRGGGGHHHH!!" Crying out in pain, Kai increased his power to such a degree that he took Shokukoma, and swung like his life depended on it. So much so that it clashed with Colby's zanpaktou as he was near eye level. The two look-a-like swords hit each other, clashing metal to metal, and two separate streams of reiatsu, one deep gold, and one dim pink and silver, each going outward, clashed. Only one side would win this struggle, and Kai would make sure he would be the winning side as he pushed forward. Only the stronger side would win.
