When he was finished changing, he came back outside and did a few warm up stretches while Katrina jumped up and down on her toes to keep herself warmed up. Master Wei moved to the center of the sparring circle on the large blue mat, waiting for the other two to get into position before allowing them to start.
Ready, and, fight!"
Without warning, Katrina sped towards him the moment the spar started, unleashing a swift high kick that was aimed at his jaw.
Rather than back pedal, as most sane people would do, Harry moved forward, using his forearm to block and redirect the kick over his head. His reason for doing this was because moving backwards not only allowed the one attacking to set the pace and move after him, but also because there was a higher risk of getting hit by a follow up attack involved. By moving towards Katrina, he managed to position himself at a range that was too close for her powerful legs to actually do any damage from and left him in the position to counter attack.
After directing her leg over his head and towards his left side, Harry made an attempt at striking her with his padded fist in the larynx. If the spar he found himself were a real life situation, he would have used a knife edge strike or hit her with the knuckles of his middle and ring finger, but that could have crushed her wind pipe if it hit.
Not to say that it did hit. Katrina was quick to slap his hand away with an open palm before it could get close to hitting her. That still did not stop Harry, who took another step into her guard and used the elbow from the same arm he attempted to hit her throat with to hit her nose.
Katrina leaned backwards, lifting her leg up at the same time and launching a powerful knee strike towards the nerves near his abdomen.
Harry was forced to halt his attack and side step the knee. At the same time, his left leg came up and he further diverted Katrina's attack with his shin. Her entire leg spun away from Harry, forcing her body to go with it and leaving her open for him to deliver a swift strike to her kidneys.
Or so he thought.
Continuing her spin, Katrina managed to make a full three hundred and sixty degree turn, coming out with a surprise snap kick that Harry could not see coming due to her body being turned away form him at the time.
Harry could only thank the high heavens for his incredible reaction time and reflexes, which had always given him an unfair advantage in any sport he played in (whether it was martial arts, football, or Quidditch), that allowed him to duck under the kick. At the same time, his hands came up and pushed Katrina's leg higher as he stood up, knocking the woman off balance.
Wanting to capitalize on his sudden advantage, Harry moved in for the kill. His right hand shot out and grabbed the blond woman's wrist, where he then proceeded to pull her towards him, sending her stumbling towards him as he prepared to send his knee into her gut.
At least, that was his plan. Before it was derailed.
Quicker than Harry could comprehend, Katrina reversed their position and it was now she who had an iron clad hold on his wrist. The young Potter heir only had enough time to realize that the entire set up had been a feint before Katrina spun around so that her back was facing him and used his own weight and momentum to toss him over her shoulder.
Harry quickly found himself airborne, his body flipping over Katrina's, his wrist still clamped in her hands. The young man just barely managed to twist himself over so that he landed on his feet and not his back as the young blond woman had probably planned.
He must have surprised her because there was no follow up attack. Deciding to use his small window of opportunity, Harry managed to free himself from her grasp, placed both hands on the ground, and sent a powerful double mule kick towards the woman.
It didn't hit. Whether she was surprised or not, Katrina had a lot of combat experience, and her body was predisposed towards reacting with very little thinking on her part. It was instinctual.
She moved backwards exactly two steps, ensuring Harry's feet would miss her by the smallest of margins. Katrina than came back in, slapping his two feet so that his legs spread apart before they hit the ground, then sent her heel directly into Harry's kidney.
The young man grunted in pain as he felt the blow to his body and collapsed on the ground. Thankfully it was diminished, both by the fact that Harry knew a breathing method that allowed the damaged area to 'deflate' a bit and cushion the blow, and Katrina kicking him with less force than she would if the fight were serious.
