"Shit!" Akio swore under his breath, quickly realizing that he had no choice, their simultaneous attack had left no other way out... Akio leapt high into the air, causing chaos to unfold as everybody would now hit each other instead of himself. However, now that he was in the air--he was very limited to what he could do due to the fact he was primarily an earth and water style user. But he had a plan for everything, and being in the air was no exception.
Once he got several hundred meters in the air thanks to his powerful chakra jump, he preformed a front flip using his momentum and began a dive back towards the ground. He began enhancing his strength immensely with chakra and once he was meters away from the ground, prepared his attack--he violently crashed his chakra enhanced fist into the grass, causing the dirt underneath it to shoot upwards and becoming visible. He was planning on directly hitting any of the teenagers, he hit the ground hard enough to the point where some of dirt would actually become loose and cause the students to sink as the ground beneath them collapsed.
He stood up straight as the dust from the attack was all throughout the training field, and was facing away from the teenagers, Akio proceeded removed his flak jacket and threw it aside. "Just slows me down." Akio muttered to himself aloud. He turned back around and send his chakra directly to his hands, showing that this was the part where he began using his enhanced strength on them. While he would be surely holding back and be sure not to break any bones, he'd also be sure to knock the wind out of them if his taijutsu connected. He looked at the teenagers and shouted, "Now I must say, I did like your all's attempt there. Especially Rin's! She used strategy, but kids, the problem is..." Akio then pointed to his temple, "You aren't communicating with one another! Tell each other your plans! Come up with one grand scheme against me! Now, this will be the last time I'll give you all a chance to correct your assault before I stop holding back! Again!!"
