Kudo Gin Age: 10 years 9 months old .
Gin and others were guided by Tsunade's shadow clone for nine days of training. After Gin's body was completely energized, he could handle long periods of training now . So he just focused on training his body without weights . He trained the basics of Strong Fist Style which were basic thrusts , low kicks etc.
Simply put , Gin continued to break the small limits of his body back to back because he wanted to increase his chakra level as much as he could before he was sent to the war battlefield . With more chakra , he could fight for longer time and kill more enemies thus earning more stat and skill points . For the time being , Gin had already decided which skills he wanted to purchase from the shop .

He can learn ninjutsu himself easily when he gets perfect affinities and shadow clone jutsu after all . It would be long time when he gains so many points and until then his chakra would have reached great heights . When Gin attained perfect chakra control, he wanted to learn few useful medical ninjutsu from Tsunade and her chakra enhanced taijutsu . Gin had confirmed with system that he can easily obtain skills and level them up through constant practice much easily than others . So Gin wanted to use shadow clones to master many useful skills in future .
Currently Gin was outside Minato's apartment because he had been invited by Minato to visit Jiraya . Gin wanted to gradually bond good friendship with Minato so he did not refuse as both of them were free . He had no idea why Jiraya wanted to meet him though .
Finaly Minato opened the door and stepped outside. He wore black pants and white T shirt which looked great with his baby face and blonde hair. Gin also wore simple clothes which were black boxers and white T shirt . The thing was that both of them were orphans and did not have much money. So they could not buy expensive and stylish clothes .
" Yo.. Sorry for making you wait Gin kun . Ah.. I started enjoying my bath and almost forgot our meeting time . " Gin looked at the innocent smile on Minato's face and thought that no wonder even the hot tempered Kushina cannot get angry with him .
" Its alright . Anyway, do you know why Jiraya sensei has summoned me ? " Gin got straight to the point as both of them started walking towards Training grounds no 3 which were located on top of Hokage Face Mountain.
Minato scratched his head awkwardly because he sometimes cannot guess the thoughts of his sensei at all . Gin understood that Minato did not have any idea so he dropped the question immediately.
" Gin kun , Kushina chan is still very sad . I have tried many things to make her happy but nothing seems to work at all . Tell me , what should I do now ? " Minato was genuinely asking for Gin's opinion on this matter completely unaware of the fact that he had no romance experience in both his lives .
Gin continued to hop over the roofs while his mind thought about the situation of Kushina. After a while , he smiled because he realised that she already had best companion with her to share her sadness so there was no need to worry about her at all .
" Hehe... Minato , you don't have to worry about Kushina for now. She lives together with Mito sama and Tsunade sensei . So both of them will take care of her well . We cannot understand her deep sadness because unlike her . Mito sama and Tsunade sensei are also deeply connected with Uzumaki clan so the three of them can understand each others feelings better . "
Gin at the same time also thought that Tsunade must be feeling very lonely all the time because she and Nawaki were the only ones left from Senju clan now and Mito sama was going to die soon too . She still managed to stay happy. This fact made him respect her more and more because Gin was sure that he could not have behaved like her if he was placed in the same situation as her .
Minato thought deeply for a while and broke into a relieved smile because Gin was right . He did not have to worry about Kushina now at all.
Soon both of the reached training ground no3 while happily chatting about some useful jutsu which can increase their strenght fast .
Gin saw Jiraya sitting on top of a huge rock grinning like an idiot while reading an adult magazine . He was speechless because he still continued to be immersed into his book even when both Minato and Gin stood one foot away from him . Minato looked at the book and blushed like a red tomato while trying to hide his face . Gin wondered how Jiraya had confidence to try too woo Tsunade with such habits and personality..
After few minutes , Jiraya closed the magazine and his look suddenly changed into a completely serious one . Gin was surprised because he was not capable of changing his mood so easily in a moment.
" Cough .. sorry for making you wait Gin kun . I heard from Tsunade that you were researching on a new jutsu which had interesting theories behind it . So can you share your theories with me ? Tsunade told me to help you so I told Minato to bring you here when we have some time.. "
Gin looked at Minato who was shaking his head because Jiraya had only told him to bring Gin here with him . Gin smiled because they were asking about a jutsu which Minato was going to invent himself in future . Naturally he did not mind sharing it with them.
" Actually I have completed the jutsu already but I feel that it has potential to evolve more so I casually discussed it with Tsunade sensei two days ago . Here , look at this baby."
Gin extended his right arm and opened his palm . Suddenly blue orbs of light started swirling at great speed on top of his palm and after a second , the transformed into a basketball sized blue chakra ball . If you look clearly that you could see that huge amount of condensed chakra was revolving brutally inside the ball but it was not losing its shape.
" Hehe.. it's called Rasengan . Here , look at its power first . "
Gin bent down and thrusted his rasengan slowly into the solid ground which was being destroyed like clay inch by inch as slowly the rasengan traveled downwards without losing its power. Of course Gin could have thrusted the rasengan with all his strength but then the impact would destroy few meters of ground. Gin was sure that Jiraya could see the greatness of this jutsu by this simple demonstration after all he was a future sannin .
As expected Gin glanced at Jiraya's wide open mouth after he dispersed his rasengan which easily dissipated into thin air because it was just a condensed chakra ball . Minato on the other hand was confused by his sensei's shocked expression because to his eyes, the jutsu did not seem much powerful at all ..
" Hahaha.. Gin kun , you really created an amazing jutsu . Rasengan ? Ha... what a fitting name for the jutsu . So do you think you can teach it to me ? "
Minato was stunned as he saw the serious expression of his sensei as he asked his friend to teach him a jutsu politely . He could not help but Express his thoughts on the matter. " Sensei , why are you so excited for such a weak jutsu ? Even a D rank jutsu has more power than that .. "
Gin immediately flashed a mocking smile at Minato because the real inventor of the A rank jutsu was underestimating Rasengan himself. Jiraya just signalled Minato to stop his mouth with a hand and continued to look at Gin with determined expression..
Gin naturally had no problems in teaching Rasengan to them because with it they can more easily end their future battles . " I will tell you the simple methods to train the jutsu now. "
After that Gin started explaining to Jiraya about the methods which he himself had taught Naruto in the anime . Water Ballon , Rubber Ball methods. Gin also bragged that he had discovered that Rasegan was pinnacle of chakra shape transformation and all.. with a straight face because he wanted to instill inside Jiraya's mind that Gin was a genius ..
Actually with Gin's current chakra control, it was easy to master Rasengan because he just had to train according to the simple right steps . At night when Gin was free inside his apartment, he decided to practice rasegan on the roof . He mastered the A rank jutsu in just 3 nights and used two more nights to level it up to max because due to possessing system
, he just needed to practice same justu back to back to gain experience with each success and gradually master it completely.. When Gin discovered this convenient function of the system , he immediately changed his future plans and decided to practice many jutsu himself using shadow clones ...
