I do not own Naruto. I do own the Book of five rings. At least my copy of it.
"Ashina...Uzumaki!?" Naruto asked incredulously as his eyes widened after not only hearing the name, but Uzumaki clan! The old man certainly looked like he could be a leader as Naruto observed him more closely. He had long white hair and a shared off goatee, with black samurai like garb along with two cool looking bandaged swords that were strapped diagonally across his back.
"Yes, and if I'm not mistaken you must be the son of my granddaughter Kushina. You look exactly like her, except for your hair and eyes. Tell me how has she been?"
Naruto just looked confused for a moment before being overwhelmed with sadness as he replied." I..never knew my mother. The orphanage said they probably just abandoned me because I was a nuisance, and the old man said he doesn't know either..."
Ashina looking appalled instantly grabbed the blondes shoulders firmly and told him." You're Kushinas son, I'm sure of it. Even your chakra feels the same as hers, and I bet you can even manifest the Uzumaki Attacking chains with a little practice. Regardless know well that you're not alone in this world, as you come from the clan of the greatest seal masters to ever walk the earth. Our clan is even capable of using the shinigami itself, although it is most fortunate that you didn't place That mask upon your face! You earlier asked me what is sealing, and as it's your birthright I will show you the power of seals here and now. While commonly seals simply store an object inside of another object bypassing the laws of space and time, there are a great many other ways to use it. For example..."
Naruto didn't even see the old man move before both of his curved blades were in his hands and he turned around before continuing speaking." Handseals are the bases of ninjutsu and genjutsu and as you know they use the hands. With seals however it is possible to use those same techniques with no handseals, by using a seal that was already drawn and simply channeling chakra, like so."
Naruto drooled right them and there as the Ashina smoothly swung his blades, and a wave of water exploded from them as Hugh speed. Then a bolt of electricity shot into them, increasing their potency as the man smirked at Naruto's expression of awe. Then he swung them again and this time a storm of fire appeared swirling into a tornado of blazing hot flames. Stabbing a sword into the ground a wall of earth appeared even though everything was white, and stopped the deadly twister before he swung the blades again creating a gust that caused the fire to erupt and explode shattering the earthen wall.
Naruto couldn't stop jumping around screaming as Ashina turned back toward him smiling at the boy's excitement. He was just like Kushina when he first showed her the same thing, except he didn't ask him for his swords immediately.
"GRANDPA THAT WAS SO FREAKING AWESOME! CAN YOU SHOW ME SEALS TOO. CAN I HAVE YOUR SWORDS! THEN I'LL BE HOKAGE FOR SURE!"
Well, Ashina stood corrected. At least now he was 200%positive that this was his great grandson of nothing else though. Laughing at the young Uzumaki Ashina replied." All with good time my boy, but first let's see if you can manifest the Uzumaki Chaka chains like your mother. What I want you to do is send your chakra to your fingertips, but don't try and shape it. Simply let it flow in the circular motion that all Uzumaki chakra flows in. Our clan is famous for our chakra as well as our seals, and we are also renowned for our kenjutsu. Now focus and do as I told you."
Naruto nodding his head in determination immediately complied and tried his hardest to impress his great grandfather by doing it the first attempt. And he failed. The boy a just looked like he was constipated which caused Ashina to chuckle at him with an amused look in his eyes.
"Relax Naruto. We'll have quite some time here together as I created this shadow clone while my chakra was at full capacity. Therefore I am at half of my normal strength. Now just calm yourself and let the chakra flow."
"Wait umm..Grandpa..what's a shadow clone? I'm still in the ninja academy and the one thing I just can't do is the clone justu. They just always come out pale and sickly before dispersing."
"Hmmm. The clone jutsu you say. I can feel your chakra quite easily and from the effort it took before your chakra began to flow I'd say you lack the control, and you just have too much chakra. It's actually a common occurrence with our clan. The smaller techniques are vastly more difficult than the ones that require large reserves. I suppose in those instances you could say were too strong for our own good. How about I show you the shadow clone jutsu, and if you can master it I'll tell you where my swords most likely are. Deal!?"
Naruto's head practically touched the ground as he nodded with anticipation to the amusement of Ashina. After being shown the ram handseal and hearing the explanation and purpose of the technique, Naruto finally managed his goal of impressing Ashina after several failed attempts. There now stood three Naruto clones in front of them both, and examining them closely Ashina then told him." Excellent. I truly didn't expect such progress in such a short amount of time. Now your next step will be to eliminate the smoke and the noise, but I believe you can handle that on your own later. You have earned the right to my blades, and I will tell you their name along with where they mist likely are when I feel myself getting weak. For now continue trying to manifest the adamantine attacking chains, but this time use your clones to help. Since everything that they learn you learn as well, you'll find that your skill will increase exponentially in a shirt amount of time if you're dedicated. Now begin!"
And so it went on for hours before any real progress was made, and eventually seeing Naruto was struggling and possibly couldn't perform the chain technique Ashina halted him and told him to create a few more clones to keep trying while they talked and tried other things. Ashina asking Naruto about his taijutsu skill was literally sickened by the sloppy form that was demonstrated to him, and took it upon himself to introduce Uzumaki taijutsu to him. The style was actually created by his great grandmother, Wing Chun Uzumaki, and as such was called Wing Chun. She had created it in order to combat a large skilled male fighter who was hell bent on marrying her, even if force was necessary. And so she had made a bet, which Naruto had learned Uzumaki were also infamous for. Being gamble addicts with freakishly good luck, he'd just have to try it out sometime. Anyways she ended up beating the guy into the ground, and the simple movements which she had adapted from a difficult style based on cranes were actually pretty easy to learn.
The guiding principle was protecting the center line, the imaginary line that most of the points where you could be badly hurt were. There were the eyes, nose, chin, neck, solar plexus, and groin altogether. There was also the knees to consider, since a simple low kick could disable even a skilled opponent if it wasn't telegraphed. And so Naruto learned the style much to his pleasure, with the main techniques being the chain punches, the side kick to the knees, and the one inch punch. There were also different sensitivity drills he was shown, including a few called lop sao and chi sao which Ashina seemed to place great emphasis on. Despite his quick learning of the simple style, Naruto felt as if it wasn't natural to him, and voicing this expecting to be reprimanded he was instead confused by his jijis chuckle. Then the old man just told him." That's fine Naruto, no one is exactly the same. What may work for me may not work for you, and that goes for a great many thing in the world. Learn all you can my boy, and create something new that fits you. That's the Uzumaki way, and don't ever forget where you come from! Understand!?"
"Yes sir Jiji, I get it. But I'll still always cherish this Wing Chun and I'll even make it better. Believe it!"
"Oh I believe it my boy, and now we can begin your kenjutsu training!" Ashina said as his own excitement was steadily growing. His young descendent showed true potential in both nin and taijutsu, and he was wondering how he would take to kenjutsu.
"YATTA! LET'S DO IT JIJI! Wait..uhh..How can we if I don't have any swords to use!?"
Smirking at the boy's enthusiasm Ashina replied saying." That won't an issue, as you can already use the shadow clone jutsu Naruto. Just use it to create two clones along with a transformation, and shape them into swords like these. It can also work with anything else you'd like to replicate, like kunai and shuriken. Try it."
Focusing Naruto managed it the first try, creating two curved swords exactly like Ashinas own which he held in his hands with two fingers.
"Good..Very good. Now the name of my sword style is called niten ichi ryu, and it was created by my grandfather Musashi Uzumaki who was known as the strongest swordsman alive during his time. The true essence of the two heavens one earth style is the state of mind and strategy, but since I have all of that within a book I'll be showing you the techniques. Know this, you can have all the techniques in the world but they are meaningless if they can't be applied. That is why strategy is essential, and there hasn't ever been one person to exist that completely mastered the way of strategy. It's impossible to do so, but with much training and reflection one can become proficient and use it toward any purpose that can be thought of. This is the essence of strategy, to be useful in all things and to allow one to think and plan clearly and effectively in any given situation. Now here are the basic stances I'd like you to learn before we move on to some techniques."
And so Naruto spent many hours learning how to hold two swords and wiped them together fluidly, and although his technique was choppy Ashina praised him saying he picked it up rather quickly. Even faster than he himself had. It was during this time that he taught Naruto many principles that pertained to the world in general as well as combat, and the blonde took everything he learned to heart. It was truly a dream come true finally meeting a family member, and finding out that he was a Kage himself motivated Naruto live up to his name as well as the Uzukage entirely. Her become the best seal, kenjutsu, and strategy master to ever have lived, and the m Sakura would definitely choose him over Sasuke!
Eventually his clones made headway in the chakra chains by creating a small link that extended from his index and middle fingers, and the thick chakra weaved through itself several times making it about four inches long. It wasn't that great, but it did mean he could prove on it! Ashina then let him know the full capabilities of the technique, along with the style that his mother had used when she was alive. After that Naruto spent much time continuing to learn, and he got to know his jiji a lot from his stories as well as his life lessons. The old man was truly wise, and Naruto had learned more from him in that one Fay then his entire two years at the academy.
It was after what could have been his 500th simplified kata that Ashina informed him if his low chakra, and getting teary eyed Naruto begged the man born to leave him.
"Naruto listen to me. I am very proud of you and I know all your hopes and dreams will be achieved. Remember that family is what's most important, and find yourself people who you can love and trust. Remember everything I have taught you, especially the principle of spirit and will. Even if you defeat an opponent in battle, if you haven't crushed his spirit he WILL return. True victory is something that cannot be sent, and never let anything break your will. You are Uzumaki, and Uzumaki are indomitable in spirit. To find my swords, seals, and book of five rings you must journey to Whirlpool, our ancestral homeland. There near the center of the village is a large tree, and it blooms white flowers during the spring. Dig beneath that tree and you will find a small container, and when you open it you will find a scroll. Use your blood and chakra to open it, and you will find my legacy within, along with my journal. My blades are the 5 elements swords. Know that love you dearly my child and we will see each other in the other world when it is your time. Now go, and move forward never looking back!"
Suddenly Naruto was back in the dusty shrine of masks, and he instantly began crying as a humongous smile adorned his face.
"I..sniff sniff...I love you too Jiji. Thank you. I'll be the best that ever lived and I'll always protect my family. "Believe it!"
He considered grabbing another mask to try and see Ashina again but suddenly his stomach grumbled loudly and he almost collapsed from exhaustion. Damn just how long had he been laying there for!? Groggy and tried he then exited the shrine of masks and channeled chakra reactivating the seal that kept it shut from non Uzumaki. Then still smiling he began his slow trek toward the village wondering how he'd make it all the way to Whirlpool. His solution was quickly found when an all white owl decided to make its presence known, swooping in and capturing a small rabbit silently and efficiency. Naruto just chuckled at his idea too tired to jump around and celebrate.
~20 minutes later~
Walking at a sluggish pace through the district where the red eyed bastards that were Uchiha resided, Naruto didn't even care that they openly despised and looked down upon him. He was just too tired, and he just wanted to go home and crash and would even use this shortcut to get there sooner. But he wouldn't be getting home any time soon.
He could smell something in the air, and it was something that he recognized purely from experience. But what was it!? Stepping in a pool of dark red liquid, and finally noticing the body nearby as he rounded a corner, his question was answered. Involuntarily screaming in surprise and shocked beyond belief, a masked man appeared out of thin air in front of him and stood looking at him for a moment before tilting his head and greeting him." Well, hello there boy."
