Kana was obviously not amused by his "Prank". She noted that maybe she needed a break, take some time to do some deep relaxation... But of course, Kana was hardly the kind of person to take a vacation. With a sigh, she frowned, hands on her hips. She knew Murano had likely heard about the disaster that was her last mission, and that's likely what he was trying to subtly ask about. There's no way the death of the previous Uchiha heir wasn't the hottest gossip in Nora right now. And of course Kana blamed herself, to some degree at least. 

"I'm... Fine. I've been working on some more medically orientated stuff actually. I've managed to weaponize my incredible medical knowledge actually."

She smirked lightly, because of course Kana would think about how to turn a healing art into an offensive ability.

Shit, it was a bad idea to try and "Prank" Her. He admonished himself a thousand times over in his head for it by the time she spoke up. 

"T-that's great! I'm actually kind of doing the same thing, actually. That's why I called you out here to train." He was glad to turn the topic to something else, especially medical jutsu. 

"I've been training with Chakra Scalpel and I've sort of formed my own style with it. There's this one move I really wanted to try, but It needs some work..." He realized at once that it almost sounded like he wanted to try Chakra Scalpel on her, which wouldn't exactly feel all too great. He corrected his mistake immediately, tacking on, 

"N-not that I'll be using chakra scalpel in training of course! Just like, the motions for the technique."
Sachiko
She thought for a moment, seeming to genuinely consider what the harm in letting him actually practice his technique would be. They both had a fair bit of medical knowledge, right? Surely between the two of them, she wouldn't be permanently damaged or anything. 

"Well, I mean... We both know mystical palm, right? It can't be *That* Bad... But either way, then sure, go for it."

She chuckled, stretching her arms out as a sign to "Come and hit me". She trusted Murano to not kill her after all, even accidentally. He seemed far too cautious in general for any sort of extreme accidents to occur. And hey, if something *Did* Happen, she'd have something good to hold over his head for awhile.

He didn't think mystical palm would really help if his technique succeded, considering it relied on severing the passages leading to the lungs. He wouldn't activate the chakra scalpel but would form his hands into blades to simulate using the technique. Dashing forward towards Kana, he aimed to stab forward with both hands towards the center of her chest. 

"It'd be too dangerous to use chakra scalpel in a fight. Plus, this technique was made to kill."
Sachiko
Kana stood still, resisting the urge to fight back on instinct. She'd give him at least one shot at trying out this movement before she made it difficult for him, she was feeling nice today. She chuckled slightly at his comment though, obviously finding his "Made to kill" Comment amusing. 

"I think *Most* Jutsu are "Made to kill"...But if you really think it's that dangerous, then I appreciate you not murdering me."
Nelson
Finished with demonstrating the technique, he'd fall into an offensive stance in preparation for their actual spar. He was more than bit embarrased, having realized it was a little dumb to refer to his jutsu as "Made to kill." He was telling the truth though, the jutsu wasn't like his Water Serpent where he could hit anyone or anything, this technique was made specifically to deal a killing blow. 

"Just returning the favor for not knocking my head off." He said with a small smirk.
