Ari Learned Water Whip! It's not as effective as you think

Ari carried with him a small scroll with a wax seal on it, keeping it shut tight and a larger scroll with his clan's symbol written on it and the characterized names of Manzenmasu and Samoiyamasu Junrei on it (but that scroll was for something else after this little debacle was about to go down here). Inside the scroll was information on a fundamental jutsu that his clan was known to use from time to time, but preferred to use their kekkei genkai instead. What did that mean? Well their version was a bit different but quite similar in nature, though certain members had taken this version and adapted it into new ways for subduing their targets. What was that jutsu? Plain old Water Whip. Ari moved out to the target range outside of his clan's home to practice using the water whip on some swinging training dummies. First he opened up the scroll and unraveled it across the ground. He read over the notes and illustrations, figuring that the jutsu was used for tying things up and dragging them off or just to hinder the movement of whatever it wrapped around.

"So it's like whiplash, just from the palm of the hand?" Not exactly Ari but you get the gist of it. So he went over to the wood and rope mechanism, starting up the pneumatic crank to get it going for a good five minutes so that the straw stuffed canvas dummies could strafe back and forth from their hanging positions on the rope.

Forming the handseals for the jutsu, focusing himself and not using his kekkei genkai for this, swiped his hand through the air to create a thin cascade of water that he tried to grab but it quickly turned into a puddle at his feet after his first grab at it, "Bluh. Okay round two." Again, he made the handseals and tried the jutsu, creating a whip for a moment that when he pulled backwards, snapped and cracked him square on the chest, leaving a welt and a wincing Ari kneeling on the ground, "Okay, okay. I can do this, I. Can. Do this." A few seconds passed by and he shut his eyes tight before letting out a pained sigh through his teeth as he doubled over, "Nope! That stings too much. Need a moment, or seven." Lying on the ground for about three and half moments, Ari finally was able to get up without searing pain on the center of his chest and sighed with relief.

Now he was forming those handseals again and creating the whip in the air, grabbing it with both hands like it was a pair of nunchaku. "Ha!" Now that he had the slippery bastard in his hands, he coiled it up in his left and looked at it as he let it down while bringing his arm up. "Pretty similar to Whiplash, feels kind of awkward though." He tried to crack it in the air a few times, getting that telltale sign of a whip being cracked. Once he had gotten the hang of holding it and snapping it in the air, he turned his attention toward the dummies that had been moving around and coming to a slow stop.

He sighed and looked over at the crank that would start the dummies up and get them moving again, then at his whip hand, then at the crank and then to his hand again. Rather than walking over and starting it with his hands and practicing on the dummies, he focused on the handle that was jutting out. Pulling back and circling his hand in the air to get it wound up, Ari lunged forward and swung his left arm forward, sending the whip out toward the crank, where it swiftly turned around when he lost his focus and tried to crack him int he chest again. To which he quickly leaped to the side to avoid and swing the whip for the crank again! This time he wrapped around his mark and pulled with great force that sent the wooden machine into its work cycle again, the dummies starting to move again and leaving Ari with a satisfied grin on his face.

Now he knelt down and focused on the larger scroll that he had brought with him and -- {continued in another session}
