Yanjirou's question was answered far sooner than he anticipated, but it would be nice to get away from all of the scrolls and weaponry - if only for a moment. The boy listened intently as he watched the beast of a man, listening intently to his instructions and staring with wonder in his eyes as he turned into a man of a man instead. Once he was finished, the boy immediately began trying the technique himself while his teacher continued to lay out the tools required to become better at seals and summons. It was obvious that he would have to start simple, so he began with the image of his normal appearance, just without the ears. He was perfectly fine with his eyes, but ears weren't something easily hidden.
"Dog..." The boy focused on his entire body, a strange feeling passing over him. He'd never concentrated this much on building up chakra before,
"Boar..." Another burst of chakra rushed through his body, and he could feel the power inside him beginning to swell,
"Ram." With the last thought, and ideal appearance still in mind, the boy released the built up chakra within him and felt relieved to finally have it all gone. The young Byakko's first reaction was to rush to the water to check his results, and it seemed he'd succeeded! But before he could celebrate his accomplishment, the jutsu dispersed, and he returned to normal.
"Maintaining jutsu is much harder than I originally thought..." He mumbled, stumbling forward slightly and catching himself on his knees as his head began to spin. As a taijutsu practitioner, this whole day was proving to be exhausting. Thankfully, the boy always tried to come prepared, and he quickly reached into one of the pouches on his side and pulled out a blue liquid contained within a glass vial. Popping the top, Yanjirou gulped it all down in a moments, feeling rejuvenated as it passed through his body. With a quick shake of his head - in an effort to get the taste out of his mouth - the boy returned to his tutor and sat back down in the sand.
"Thank you, Kuro-san, for teaching me that. I'll have to practice on my own time, but for now I'll return to the scrolls." He said, already reaching for some of the new items. Now that he'd managed to seal one of the items available in a scroll, it was time to try and take it back out. This was another technique he'd read about, and it seemed far simpler to do than sealing it. The boy lifted his thumb and bit as hard as he could into it, flinching as his teeth sank in. When he looked to see if it was bleeding, there was no difference.
"I suppose my first challenge is getting through my own skin..." He mumbled, trying again and again until he finally got it. Once the red liquid flowed from his fresh wound, the boy placed his thumb on the sealed scroll and made a simple hand sign, calling forth his chakra as he'd done before with the transformation jutsu. This time, however, he focused the chakra into his thumb until a puff of smoke appeared, and a kunai with it.
"As I thought, summoning is easier than sealing.." He now knew how it would feel if he ever needed to seal something again. And that was awful, of course. But with the basics out of the way, he would need to make sure he's able to do it whenever he needed to, so the boy resealed the kunai into the same scroll - which turned out to be far easier when the scroll already has a seal - and began trying to seal and summon other items. After a good hour of doing nothing more than playing around with what was available, the boy placed his hands on his knees and let out a sigh of relief.
"I believe I have this down well enough, Sensei. For the past twenty minutes I've been able to seal and summon items with little to no trouble, and the only thing I've accomplished recently is tiring myself out from all of the chakra I've used." Yanji stated, looking up to the man that was watching him. What would the next step be? Or would he be told to continue practicing?
