30 against Tsunade! 1

a week past since Tsunade took Saruto as student, in this period, she didn't teach him anything remotely relevant to healing jutsu or strength, but start with the basics, first she decided to calculate how much chakra he has, because the amount of chakra is inversely proportional with how the difficulty to control it, that doesn't mean that people with huge chakra are always bad at control it, just much harder to achieve that

she is the best example, while her parents weren't mentioned the series, but her grandparents are people who blessed with massive big ass chakra

and while chakra reserves aren't directly inherited, a huge part of it relay on bloodline, so she got a huge pool to take from, that was throne in her path, as her dream was to be the best medic in history , her massive chakra stood in her dreams, but fortunately, she was a genius, and invented the hundred strength seal , making most of her chakra reserve sealed away while focusing on control, thus achieving her dream.

so she needs to know if Saruto is even fit for such training, she hoped so, as she took liking for him, not that she would admit it..not when she is sober anyway...

so first she gave him the hand seals for muliple shadow clones, she didn't care if that's forbidden jutsu in her village, her old monkey teach can try throw his poop at her for all she cares.

anyway, after she did that, she asked him to do the seals and try to make clones at much as he could, but her jaw almost fell down when he did a whopping 200 clones, that's not big deal, even she could do that if she unlocked her seal, but 200 shadow clones not even 9 years old? she was flabbergasted!

and then she immediately wanted to know how much control he has , soon afterwards she tells him to do the walking on water/ trees exercise

and she was astonished even more!

*sometime on the first week*

"wha...what are you doing?!" she said dumbfounded

"hmm? what do you mean big sister? I'm relaxing." Saruto asks tilting his head and relaxing on his back

"that's exactly what I'm mean! how can you doing than...on the surface on the water!"

"I mean... can't you?" Saruto asks confused

Tsunade almost fell "of course not! I mean I can, but I won't! who can relaxed while being wet! especially in cold water on the lake!, besides your are wasting chakra! if you doze off, you will will lose control,and drown!"

"oh!" he hit a fist on his palm and a sound come out and said in relaxed matter "don't worry big sister tsuna, neither will happen to me."

Tsunade looked skeptical and she jumped into the lake near him, but she noticed two things, one his clothes aren't wet, two a very thin blue layer is around the water is touching it, she had wide eyes as indeed, he can't get wet but said "even so, that doesn't explain why you won't drown." she crossed her arms, making her full marshmallows jiggle.

that made Saruto lose focus a bit, this made Tsunade smirk internally, she knows that her new disciple is quite a pervert especially someone for his age,she guess he would an early bloomer, like some she knows, similarly had a close hair color to him, but the difference is that he didn't show the degeneracy the old sage pervert usually shows, for example at one time she asked him if he wanted to join her in a hot spring in a teasing manner, he casually agreed to her surprised as she thought he would be shy about it, then she said it was a joke and he must go the men section

she thought he would be upset, anyone would, a beauty invited them to bath yet she backed off, and indeed he was, that made her a bit disappointed, as she thought he would be different, but soon was surprised as he wasn't upset for the reason she thought it was...

he did get annoyed because he didn't get to join her, he wouldn't deny his nature as man, even an extremely young one at that, to her at least, what upset him that she backed at her word, but not the situation itself, Tsunade find it quite pleasant to know that the boy she decided to teach have great dislike for breaking someone word, this made her remember her past a bit and her heart soften, so she apologized and said he can join her for real, she thought he would refused, as he was quite upset, but his displeasure disappeared and made a big smile made her dead heart skips a beat, she shakes her head in denial and repeated 'I'm not like the snake, I'm not like the snake' and Saruto agreed in excitement, the mood swings he have made her amused.

remember what happened in that day, made her smiles subconsciously, she knows that this action might distract him and that's her goal, she wants to know what happened if he lost focus of his chakra, but to her puzzlement even while his eyes on her pair of pillows, he didn't fell, hell, his clothes still didn't get wet! this made her extremely curious and didn't even bother to scold him for staring at her for long time

"how?! how can you do this!"

"heh, I can even do this!" he said is he put his head on the water on sleeping position and see and behold , he is actually sleeping! while activating chakra! on the water surface! without being wet!

"...I feel like exploring a new lands.." she said with a sigh but thought 'what an amazing chakra control! and I feel whatever is he doing while sleeping is the reason for such results. I won't be worried now, he will be able to grasp my technique like a fish in the water..and with such fine control...he maybe able to achieve my strength of 100 seals in record time!..but first.. time to test his strength!' and picked up the sleep Saruto and head back home...

****

present time, in the field as big as a football ones

Tsunade stood infront of Saruto with hand on hips and said "good! for a week, I tested how much chakra and control over it you have, if I used myself as a scale, in chakra I'm triple you and control I quadruple you, this might discourage you if you don't know that most jonin don't hold 5% of my control! so you are 5 times better than average jonin! I don't know what the hell you did before you meet me, and frankly I don't care, but from today you are mine!" she said in no discussing manner

"ehh! big sister is so bold! don't worry if you give few years I'll be able to be yours truly!" he said in teasing smile

Tsunade knows her shameless know no bounds but even she had to give the hat for him for having such unbreakable thick skin!

so she said cracking her hands "fiiinne, if you manged to survive and take everything I gave to you until you...grow up, I'll consider it."

"hoh? is that a bet?" Saruto asked

"if you want, that so be it, I won't have mercy on you tho, don't worry, you won't die..not on my watch anyway" she said while giving big eat shit grin and continue "now! for today, I want to know your limit! everything you got throw it at me! don't hold back... because I won't!" she said kicking the ground to reach him in high speed

he didn't have time to think and took a fighting stance and get ready to receiving the blonde sanin attack!
