"Indeed, i shall use the remaining years in this nation to my advantage, and get stronger for my people." Looking towards the chunin in front of him, Gihachi would separate his hands fully as he began to weave hand signs, for a specific technique he had practiced.

Puffing out his chest, as he upper torso began to bloat and his throat widened some, a reddish-orange light began to seep through his pale skin trailing up his throat as he opened up his mouth, and released a large fireball which traveled towards a nearby tree. "Fire Release: Great Fireball Technique." He kept his tone mellow, as he showed off his singular elementally-based ninjutsu technique. He could feel the slight tug of his chakra, due to his lack of pool, and control. It sucked, but that was exactly why he was here with the Captain, getting better and improving steadily. 

"I have recently found out my element-nature, which is fire. Sachiko-Sensei that i had gotten lucky, as it was a very good element. I have yet to see any other person with it, surprisingly."

Murano watched as he hurled a fireball directly towards a nearby tree. Oh, he hoped that wasn't an especially important tree or anything. Would it be taken out on him if it burnt down? Matters aside, it looked like his control was atleast halfway decent for somebody that'd only recently become a genin. It gave him a good sense of what Gihachi needed to learn first. 

"Fire's good, it's strong. I know only a few Fire-Release users myself, but they can handle themselves in a fight if need be." 

Now, it was time to get down to business. Murano quickly switched to tutoring mode as he said, "Your fireball was good, but it lacked a shape. As I was saying before, visualization is the key to proper chakra control. When you're throwing out those hand seals and preparing yourself for that fireball, you really need to think in your mind of what you think the best fireball would look like. Do you understand?"

"Maybe you could refer me to some of those fire release user's.. I am also in desperate need of learning how to improve in that region as well." He said, as he continued to watch his tutor, and listen to the things he was explaining. Everything so far was making sense, as Sachiko sensei did gloss over visualization for ninjutsu, albeit not specifically for chakra control. He could comprehend on how it was important, which was good. 

"Yes. By visualizing, one could imagine what they want inside of their head, and use that imagination to create complex shape manipulation for the element. I practiced for hours on how to shape the fire into a ball, which was rather irritating to say the least." Truthfully, the time he spent on trying to correct the shape was annoying!

Next off, he was going to perform another one of his limited ninjutsu techniques, given that he only actually knew two. It was a very useful technique, especially for a place that was dark, like his birthplace for instance. Doing a few hand signs, Gihachi would place an open palm in front of him, with it facing up into the air. Before long, a spherical ball of light would manifest from said palm, and begin to illuminate the area. "Ball of Light Technique is my other ninjutsu technique."

"If they're not busy, I'll throw them you way." He knew just how important it was to train with people that had your element. It made learning certain techniques exponentially more easy. 

"Well it's good that you understand. There's plenty of genin that sort of just ignore visualization and expect a fireball to appear and be a perfect shape. Those are often the most troublesome ones to teach, really." He didn't really mind teaching them, but it was much harder when they had this preconceived notion that was nearly entirely wrong. 

Murano watched him make the ball of light in his hand and gave a small nod of approval. "Good one to know, it comes in handy if you're on a mission in the dark. I'm actually sort of surprised you decided to learn it, most shinobi often ovrlook it because it doesn't have much combat potential."
