Not gonna lie, like half of this is world building and info in the form a of a wall of an authors note at the end of this, but any update is better then no update. Sorry this took so long
Last time on Kitsune of one thousand strings
And then the gentle sounds of a violin started flowing over the bridge, like a gentle breeze, and Itachi said a single word.
"Shit."
As the melodic music flowed over the bridge and through the hearts and minds of those gathered atop it, most couldn't help but be enraptured by it, to the point that most of the more skilled ninja attempted to dispel its beauty like a genjutsu before deciding/realizing it wasn't a genjutsu, with the exception of Itachi, who actually dispelled it three times before deciding it was just going to keep coming back and not worry about it.
"As the cruel crooks and criminals circled the hero's of our story like hungry sharks-"
Kisame grins, a thug early to his own funeral murmurs a question about how some can just talk in italics. "- they did not know that amongst their own ranks a new hero was soon to emerge. A holy hero who dyed his own hands red with blood, working in the shadows, hiding in the darkness, honing his blade and dimming his own light. All for a the single chance he would need, to avenge his mother. His father. His brother. His home. All for a single chance to strike down the obese, half bald three yea- I mean vile and intimidating villain of our story, the wretched, wealthy, war monger Gato of the 9th sea-" "stop with alliteration, it's bull, what does the 9th sea even mean" "it's my story you cotton Candy cunt, can it.*Clears throat* Gato of the 9th sea. And this was the one chance he needed, searched and hunted for all these years. And so a hero emerges."With the narration seemingly over the violin music switched out for a new song, complete with drums, a guitar, piano and what sounds like a full quire of voices, and the weakest of the thugs suddenly started, as Sakura and Itachi like to call it, Narutoing the small army of thugs and shinobi academy drop outs. Limbs, heads, severed genitalia and weapons were flying in all directions, cry's of anguish and screams of rage filled the bridge as the lone thug tore through all the others, literally cutting a path to the confusedly screaming in terror Gato, before the deep baritone of the narrator flowed over the sounds of chaos and death as a seemingly floating glove nudged Kisame forward.
"Mere feet, and a few hands and heads, from his goal, his vengeance, his destiny, our hero met his greatest challenge yet. Kisame of the seven swordsman, S rank nuke-nin, the fierce and ferocious fighter and sibling student of the lone swordsman."
Taking both note of the harmless pyrotechnics flying into the place next to Gato and between the crime lord and 'lone swordsmen' and his qui, Kisame jumped forward, seeming to simply appear in a flash of colored sparks and smoke, slamming his sword into the bridge and knocking up debris before spinning around making grandiose twirls with his behemoth of a blade, hitting the chunks of stone and wood he had upturned in the process, sending them flying just as if not more deadly then any kunai not wielded by the fourth Hokage could hope to be.
"Hoshi-aniki! I have lost everything, I won't loose you as well. Step aside so I may avenge my family, my home! Please!"
A grin came to Kisame's face as he raised his sword and took a fighting stance before opening his mouth as if to say something before stopping, slightly lowering his blade and looking around before he decided he wouldn't find whatever it was he was searching for and spoke aloud.
"Line?"
(For those that couldn't tell, the violin music was used as a medium for a genjutsu like Tayuya's flute, but no one except Itachi actually managed to do anything to it, so they assumed it was just really really good music, and Itachi knew from experience that Naruto, despite being one of the ten most dangerous, though not most skilled, genjutsu users in the world refused to use it for anything other than "setting the mood" for his gruesome performances. Its not really important, so I'll drop some world building early for those that stuck around to read this. In almost all Naruto fics I ever have and ever will write, the two most important things about a ninjas chakra reserves are volume, which can be trained, and density, which with few exceptions is more or less constant, though skilled medic nin and genjutsu specialist can compress small potions of their chakra outside their body for similar results as high density chakra. You could say that normal ninja density's range from fresh to salt water, and the reason Uzumaki's are such good jinchuriki because their chakra is like maple syrup, so when the chakra of a biju that's like steel gets shoved into their chakra coils instead of encountering next to no resistance and being free to rip and tear until it is done its slowed down so it has enough time to spread out and disperse from areas of high concentration, biju chakra, to low, human chakra. Naruto's chakra, while nowhere near the density of biju chakra, is still like solid stone, so when his chakra is in the chakra network of someone else for genjutsu and they try to disrupt their chakra though chakra control or sudden pain, which makes chakra spike and flair stronger then normal chakra control alone ever could, its no different then pouring a bottle of water on a boulder, it does nothing, though people like Itachi, who is far stronger than in cannon, or Tsunade that have stupid large amounts of chakra and control can do it with enough practice by isolating the chakra in their network and focusing large amounts of chakra like a pressure cutter. This also makes it nearly impossible for foreign chakra to effect his, so unless it completely circumvents the chakra network, mangekyou sharingan genjutsu, Naruto is more or less immune to genjutsu, but the effects of most medical ninjutsus is skin deep at best as well. This is the reason why medical nin and genjustsu specialist know how to artificially increase the density of their chakra outside their body, though only someone like Tsunade or Itachi would have the skill, reserves and control necessary to affect Naruto, and due to the fact that denser chakra takes more time to disperse, if Naruto were to cast medical ninjutsu or genjutsu on someone it would continue effecting them far longer then normal and any that are successfully cast on him would most likely immediately begin returning to their natural density and be consumed and ripped apart by his own chakra, so medical chakra would disperse almost faster than most ninja could output and genjutsu would last a dozen seconds at best unless they are continually recast. Chakra density also effects the power behind a jutsu, while volume of chakra put in mostly effects size, so from Naruto an earth wall would be several times more durable and a fire ball would be hotter, faster and more forceful than pretty much every other ninja in the world. This is why he can make Amatersu, his natural fire is blue like the two tails, and he uses the chakra control to make it less dense, into normal fire, or more dense, into Amaterasu, though he prefers to use his chakra string workaround for both, as its a technique he invented himself and is, more importantly, far faster. With the standard density decrease technique he could also make the size of his justu far far far larger, so what would normally be a jutsu to throw a couple baseball sized fireballs becomes two dozen grand fireballs or a couple hundred small ones. At the moment of writing this, just after the music started, this chapter is more authors note then Naruto shenanigans. I am deeply ashamed and apologetic. Have fun people, hope you enjoyed this optional info dump that will, most likely, be resaid during the chunin exams.)
