Sachiko
Kana mirrored his stance, readying herself to make it as difficult as possible for Murano to hit her. She didn't have any real plans to strike back at him, knowing she'd likely be able to beat him in a hand to hand spar... But she couldn't help the small part of her that found enjoyment in making her friend's life difficult. She'd wait for him to strike first, anticipating how she'd manage to avoid his strike, she knew Murano was quite fast after all. 

"No problem! I kinda like your head being attached, ya know?"
Nelson
"That makes two of us." He'd remark as he quickly lunged forward, thrusting both arms forward in a stab towards her chest. It was a bit ballsy to go for his technique right off the bat, but there was no better way to learn it than to use it in an actual spar. Considering Kana's prowess when it came to Taijutsu, he was sure she probably had a counter of some sort for it though.
Sachiko
Kana smirked, waiting until he was just on top of her before executing a swift Crimson Veering Wind to spin around him, avoiding his strike. She mentally thanked Sana for teaching her such an amazing technique, it'd come in handy so many times already... She didn't attempt counter, merely flaunting her superior maneuverability. 

"Is that really all you got? I don't think you're ever gonna land that technique of yours in a real combat situation if so..."
Nelson
He tried to keep calm and not get irritated, but her smug aura was radiant. Atleast she was acting like her usual stuff, he supposed. 

"Oh shut it, muscle brain." He taunted as he dashed towards her, performing a sliding kick towards her legs. If he was able to knock her off her feet, he'd follow it up with a quick jab towards the stomach.
Sachiko
"You keep saying 'muscle brain' like it's a bad thing. Honestly, I just take it as a compliment."

She didn't seem to be letting go of that smug look any time soon, even as she skillfully leapt over his attempt at a sweep. But seeing as how she wasn't setting out to pummel the poor guy today, she would tank the follow up hit, her armor technique meaning she'd barely feel normal blow. If it had been his chakra scalpel technique, then it'd be a different story as the slicey hands would completely ignore her armor... Maybe she should think about a good counter for that.
Nelson
Her simply taking his hit with no issue was almost even more annoying than her smug look. His chakra scalpel *Would* Be effective against her, but he didn't really want to chop up his friend's insides anytime soon. 

"Man, armor technique's almost like cheating." He said with a small chuckle. He slightly regretted not spending some time researching and learning it. It wasn't like he really needed it though, considering he wasn't exactly an frontline fighter.
Sachiko
By the look on Kana's face, it was obvious she knew exactly how annoying her armor technique was, that smug little smirk still there. She shrugged, understanding how it could be seen as "Cheating" And she mentally thanked him for not slicing up her organs. 

"Well, it *Does* Block quite a bit of damage. I mean, obviously it's useless against something like a fire jutsu or anything that's incredibly sharp. But it certainly helps absorb a bit of the impact, ya know? Now, since I've been such an awesome friend and helped *You* Out..."

She fished around in her pouch for a moment before producing a small vial of... Something. It didn't look all that dangerous, just a simple somewhat opaque liquid. With a sly grin, she'd shake the vial, holding it out to Murano.

"Why don't you help me with something real quick. All you gotta do is drink this, and I'll do the rest."
Nelson
When she produced the vial he immediately knew he'd made a mistake offering to train with her. He was now technically in her debt, considering she'd been a test dummy for his technique. He could easily tell her no, but she'd no doubt hold that over his head for quite awhile and just use someone else as a test subject for whatever this stuff was. Since he had more than enough medical knowledge to probably cure himself, he mustered his courage and took the vial from her and quickly ingested it. 

"Eugh, tastes terrible. Alright, what now?"
Sachiko
Yes, gooooood... Kana's smirk never left her face as her faithful test subject dutifully drank the liquid. In reality, it wouldn't cause any side effects other than maybe a mildly upset stomach. But hopefully, he wouldn't have to worry about that if she managed to perform this jutsu correctly. 

"No, you die... Kidding! You just gotta sit there and not complain, okay? I'll do the rest."

Ushering him to take a seat, she would push aside his collar. As the "Baby poison" Would begin setting in, she opened the water gourd at her hip, she would use the water as a medium to help her remove the poison. She hovered her hands over his chest, working the water through his skin to sort of grab on to the poison and extract it. It wasn't all together the most pleasant experience, but it wasn't particularly painful.
Nelson
"Yea, yea.." He said as he took a seat on a nearby log. He'd let her push aside his collar and watched as she started doing... Something. He'd actually never seen this technique in practice before. The effects of it were certainly odd though and more than a little uncomfortable. It felt like something was seeping out of his chest but at a much quicker pace than if he were bleeding. 

"Almost done?" He asked, hoping the technique wouldn't take much longer.
Sachiko
She would simply shush him, trying to focus on what she was doing. She didn't want to mess up and like, accidentally poison him worse or something. She would never hear the end of his complaining if that happened. With a not quite convincing reassuring look, she would eventually pull her hands away, letting the now cloudy water splash to the ground.

"Alright... I think I got most of it. It's a technique for removing poisons and stuff, though it's not *Perfect*. The only way to fully counter the effects would be to let it run its course, or have an antidote. But that stuff you drank is *Super* Weak, you should be fine."
Nelson
He was not entirely confident in her assurement that everything was alright. Luckily for him, as long as he had a small bit of whatever poison she gave him, he was confident that he could make an antidote to neutralize the toxin still left over in his body. He took the small vial back from her and got back to his feet, quickly buttoning his shirt back up. 

"Not that I don't trust you... But Im going to go make an antidote at the hospital. If I end up having to stay there because I'm poisoned or something, you'll be the first to know." He said as he started his way back to town.
