Seeing the pebble approach him, Isaya raised an eyebrow before clapping his hands together as it expanded. From the air in front of him came a dense, vertical wave of wind, completely splitting the rock in two before continuing onward towards Sousaku. Both halves were thrown off their trajectory, passing right around him. 
"Assuming your enemy doesn't know your tricks is a dangerous gambit, but can help. However, direct attacks like that one will not help you out against a competent opponent. Make sure to surprise me."

So he was able to just blast the rock into nothing? No matter, he'd keep going. As the wave of wind suddenly split the rocks, he used his reflexes and urge to not use defensive techniques to evade the technique by hopping backwards again. He was keeping him at a distance, but he wanted to have some momentum if he had to dodge once again.

Beginning to run around Isaya, he prepared for his next plan of attack. He didn't turn his head, aim down to touch the ground, he didn't even move his own body aside from weaving the seals. However, as he began to run around him, his right-arms sleeve began to shred apart, now there were many nails flying towards the Chairman of the AMC, all made from his steel bracers that he wore under his casual clothing.

As the sleeves of the genin transformed into projectiles, the chairman remained motionless. The steel shards slammed into his body, before rattling back onto the ground as if they had struck a brick wall. 
"It would've been a smart assasult, if you had given me something to worry about before flinging your steel shards at me. Grab the enemy's attention with something they need to respond to, before weaving in sneak attacks."

While he spoke, Sousaku could hear a faint whirring sound coming from above and was barely able to look up before the spinning sawblades of wind came crashing down at him, threatening to sever his body in two. The chairman had given no indication of attacking, with both arms crossed over his chest.
