The Mole smiled, blood beginning to pump faster and faster as his eyes narrowed. This was what he lived for, the thrill of combat, the chance to prove your worth in the field of battle. Sure today's bout was against an ally, a comrade and a friend, but it was still a fight, and he was going to do what he always did, his best. Sojiro had started the party just the way he liked, in a full sprint towards his opponent. He was quick, and allowed The Mole very little time to prepare his defense, the boy moving with the speed and ferocity of a wild animal. This was not the first time however, that the shaggy haired boy had fought a quick fist enemy. The Mole allowed wind type chakra to form on the bottoms of his feet, waiting for the perfect moment to spring as his combatant already hunched over and dropped to all fours, increasing his speed slightly. With a flex of his calves, The Mole pushed the wind chakra through his body, energy being forced out of the soles of his feet.
This would launch The Mole straight up into the air, rocketing up about 10 meters high as sojiro would make it to his previous location. The boys deadly leg technique would come crashing down where he had just been standing, and if it was not for his wind jutsu The mole would have taken a serious blow. However the leg instead collided with the ground, sending a massive cloud of sand up into the air, and shaking the very ground he had been standing on just moment before. Hovering in the air for a second, the boy watched the area fill with sand, and while it was not high enough to reach him, it did block out the view of the ground and Sojiro beneath. With his view obstructed for the moment, he needed to even the playing field, forming another set of seals.
Taking in a massive breath, The Mole would then exhale, spewing out a massive wave of compressed air. The blast would push him back slightly as it was aimed at the ground, allowing him to hover for a bit longer in the air. "This compression wave should do the trick" He thought as the wave of wind would blast not only the cloud of forming sand, but the surface of the earth and even Sojiro himself. While the wave of wind did not deal any damage at all, it was intended to apply a massive amount of pressure. It would first push all of the sand back down onto the ground, clearing the air. It would then compress the sand onto the surface of the ground, and Sojiro with it. This would make the ground more solid, harder and not as loose as it was before. This would also apply a lot of force to Sojiro, he would have his movement for the next post reduced by 5 meters, but would also be unable to leave the surface of the earth. This wave of wind would keep his feet planted solid to the ground, meaning he could not jump or attempt to lift himself up from the ground in any way.
The Mole's cloak would begin to billow as the wind blew around him. Now that the sand was cleared out, he would lock onto Sojiro, confirming his location and watching as the gale of wind would continue to pressure the boy. Sure this technique was not very good for ending battles, but it was the perfect technique for keeping an enemy where he wanted, and out of his face. "Your move once more Sojiro."
