Here she comes! Kora performed a handsign but ended up stopping, probably because she was forgetting this was not a battle to the death. This bought him time to prepare, and he reached into his back pouch for a kunai among other things in his left hand. His fist was balled tightly around his kunai handle and he was sure to conceal the other item in his posession before the flora behind him came to life. While he could have sworn he was on the side with a cliff to his back, he forgot that there were still some trees nearby. Despite his Byakugan, having forgotten her ability to somehow manipulate nature as she did failed him and resulted in his torso and his arms being held. He still managed to hold onto his items well enough, but Kora was already moving in to take the advantage he made so obvious to her before. She was foolish to count him out like she did, and he already had a plan in mind to end things. His arms still burned, but hopefully he could pull it off.
Charging from across the river, it gave him time to both expel chakra into the ground beneath him and prepare to endure her attack. When she came to throw it towards his torso, he kicked at her arm with his right foot and threw it of course while in the meantime preparing to free himself by expelling chakra around his torso and arms. The expelling of her chakra still managed to connect with his side and knock the breath from his body. The force dragged him back a foot or two and he quickly tried to regain his bearings. He only had one chance at this, and it was up to these next hits to finish this battle for good. Her exterior could take a hit, but she couldn't train her internal system to take his blows.
Gathering the water for her hammer to take form, he was busy making certain his chakra was dispersed below the ground evenly. He was accurate, and made certain her hammer was reared up to its maximum height before it fell. Dropping the kunai, he instead flicked the two of his flash bombs that he kept hidden in his left hand and, using his fingers only, made sure to trigger them with a sharp and compact air palm when they were just inches from her eyes. Shutting his own, Kenshi would trigger his chakra to flare around his arms and torso to give him room to free himself from that hold, and lastly, the chakra he let pour beneath them would raise both of them up. A blinded Kora spinning around out of control with a newly freed Kenshi who was putting all his strength into this next series of attacks.
Lifting the both of them up at the same height above the ground below, he would approach her twirling body while her sight was gone. Grabbing her shoulder, he would begin to send the both of them back to the ground. Holding onto her, he began to initiate his 128 palms, hitting her chest, arms, thighs, everywhere in reach. "2 Palms! 4 Palms! 8 Palms! 16 Palms!..32 Palms!" By the time he reached that mark, Kora's back had already hit the ground and he was free to use both his hands to strike her repeatedly while her body twitched and hit the ground hard repeatedly, enough that a dust cloud was beginning to form around them."..64 Palms!" unbelievably, his hands weren't able to be kept up with at this point and he was hitting every single point twice to ensure her muscles and chakra would fail her while he crouched over her. With the second to last strike, he hit her hard enough with his fingers that she kicked back up from the ground and her body was raised a few feet into the air, leaving him to leap over her and push against her back to lift her up to her unsteady feet.
Rotating in front of her while she still faced the opposite side of the river he would finish the last assault he would bring her with a strike so powerful the delay was at least three seconds until her body would register what happened. "Eight Trigrams 128 Palms!" immediately the velocity of the strike would reach her and, combine it with and air palm to seal the deal. Her back would crash against the cliff and clear the dust his strikes had left in the area. "Don't get up." he turned his back to her. At least one of his arms was unusable from here, and he placed 80% of his overall chakra into striking her, but blasting her into that cliff to knock her out for good.
If she was somehow conscious. If she could somehow take all that he gave her. If she could even open her eyes after all of that, then she deserved to win. He'd let her win this fight. It would have been over a long time ago if it was to the death, but luckily it was not.
Catching his own breath, he allowed his Byakugan to rest. If she could pull herself free, he'd hand it to her. There was no reason to continue it any more. If she could defend herself despite how blinded she would have been from those bombs, well, it was good for her. His side still ached from her strike and he had had it for today. He held his breath to see if she could endure 128 strikes of internal pain and still continue.
