He waved back, and watched as the chunin met him with a warm and relieving expression. He was a kind person! It almost made him want to shed a few tears, but he would not lose his composure in front of someone he just met. *"Nice to meet you as well, my name is Kaguya Kogane."* Not wasting any time whatsoever, he walked backwards a few feet, before getting into his basic positioning. It was a rather simplistic stance, that was obviously taken from some form of Taekwondo, but matched his adaptive thinking quite nicely.

He had his left arm raised with an open palm pointing the his right side, while his right arm was at his side with a cupped hand. He was supporting his weight on his left leg, and had his right foot touching the ground on his toes, using only his toes to support h his balance as he spoke. *"Come at me please. I need to get stronger, as fast as possible..."*

Hm, seemed like the genin was a nice enough guy. He was glad, that would make this all the more easier. He also seemed eager to get on with the training, which was admirable in it's own right. "We'll do a quick test spar and I'll give you my advice after." 

He wasted no time in attacking Kogane after his invitation. Quickly withdrawing both hands from his pockets, Murano lunged forward to deliver a series of quick jabs aimed towards Kogane's stomach. He wasn't so much aiming to do damage as he was trying to see how Kogane would respond.
Barry
*"Alright advice afterwards-"* He was not ready for the burst of speed towards his own position. Unfortunately for Kogane, he didn't have the speed to dash back so he grounded both feet and took the many jabs to the stomach, by activating his C-Rank Armor Technique, he took the attacks. *"Better late than never to testing this out.."* He said under his breath, referring to the armor technique.

Afterwards, the Kaguya would jump in the air with a spin, in order to attempt a spinning downwards axe kick into the chunin's skull. *"Hmm, let's see."* Kogane's movement were obviously pretty sloppy, and there was a lot of wasted momentum, not to mention movement in general.
Nelson
Armor technique, huh? That was a good idea, given the circumstances. He made a special note to ask Kana later about the best way to counter the technique. Seeing the Kaguya flip into the air and attempt the downwards kick, Murano deftly stepped to the side and voided his heel just before it made contact. Simultaneously, he'd thrust upward with his palm towards the genin's chin as he fell downwards. He didn't put much force into the strike, instead letting gravity do most the work. 

"Good moves, just a bit sloppy." He casually remarked.
Barry
He watched as his kick was dodged, as a open palm headed towards his chin could be seen making contact with it, and it pushed him backwards indeed. Luckily, he activated armor technique in that area as he placed his hands on the ground, before pushing off his hands and onto his feet, sliding a few inches. "I see you're quite good." Compared to himself anyway. The Kaguya got into a straight position, before bowing and walking closer to the chunin.

"Thanks for showing me what you're good at, do you wish to continue or just give me some advice?" In all honesty, Kogane kind of wanted to get a little physical, since he hadn't gotten into a fisticuffs in a few months. Not a good one like he wanted to at least, since the one with Shizurama was just some endurance training where Kogane let him rough him up.
Nelson
"Thank you for the compliment." Murano replied, relaxing his mucles as the fight was now over. He stashed his hands back into his coat pockets and listened intently to what Kogane had to say upon his approach. 

"Think I've seen eough to give you atleast a little bit of advice. One of the first things I noticed was that your movements need to be refined a bit more, there was some wasted momentum and movements. It's nothing major, happens to pretty much everyone. Other than that, you have really good form and your reflexes are pretty sharp." 

He hoped that he'd explained himself weel enough, he knew that sometimes he sort of talked too fast and didn't quite convey his advice well. "You got all that?" He asked.
