Here's chapter four as promised and expected
we roll:

FLASHBACK TO WHEN NARUTO WAS SIX

naruto was sitting in the corner of his room, sobbing to himself
today was his sixth birthday and just when he came out of his favorite ramen stand, he was greeted by a mob of cursing villagers, calling him demon and damning him to hell for killing their families and beloveds
as he cried himself to sleep, he suddenly noticed he couldn't feel the moonlight on his face anymore
he opened his eyes to see himself in what seemed to be a sewer way with pipes running all around him
he saw a light at the end of the tunnel that shimmered red and behind him was utter darkness, and being a child, he was still terrified of the dark so he decided to go to the light.
as he approached it, he entered a room with a giant barred gate reaching to infinite darkness with a paper on it that read "seal".
"hmm?...kinda early for you to meet me no?...shrimp?"
"wh…who's there?"
"come closer so you can see gaki…"
 as he approached the bars, suddenly three giant claws flew toward him and if it wasn't for the gate, he'd be thorn apart now
"shit…missed"
"WHOA…Y..YOU'RE THE KYUUBI!" he said with wide eyes since now he could make out the giant orange fox with his tails lashing behind him
"wrong…I'm your fairy godmother"
"…."
"what?"
"what are you doing in here?...and where am i?"
"you're in your mindscape kid…and I'm sealed inside you thanks to your father, the fourth hokage"
"m…my dad's the fourth hokage?"
"sure…though…I think people should be worshipping you for keeping me here instead of trying to kill you…or at least NOT try to kill you for being the hero's son…damn you human are friggin stupid"
"…then…why…why do they hate me so much?...don't they know about me or about your condition?"
"no you freaking idiot
they see you as the kyuubi…as me in human form so they think that if they kill you they can avenge whatever shitlings I killed"
"th…then why did you attack konoha?...what did we ever do to you?"
"oh shut up…I was being controlled by your konoha's goddamn sharingan…madara if I remember right
I'm actually very attached to humans you know…to their females to be exact..guhuhu…their curvalicious-"
"HEY!...i'm only six so shouldn't you stop talking about this stuff?"
"you annoy me…AWAKEN!"
and with that naruto woke up to see it's morning…and not just any morning…from this day onward he knew why he was hated so much and wanted to go to oji-san before he heard something in the back of his mind
"don't even think about it kid…what do you think he'll do if he knows I'm talking to you already?"
"…then…what should I do?"
"go peeking of course!"
"and in return?"
"…I'll train you?...what else can I do in here?
I can fucking turn into a pony and give you horse-back rides"
"fair enough…when do we start?"
"when you're another year or so older
but for now…studying books and stuff…and by stuff I mean…guhuhuhu…my favorite icha-icha books"
"err…and books?"
"I think the konoha library would suffice…read all the books on human pressure points, vital parts anything"

FAST FORWARD TO YEAR 1 OF TRAINING

'okay kid…since now you have average control over our chakras…I think its time for a little jutsu training…but first…go to the weapon shop and get me a "chakra paper"…don't forget the name'
'you're not going anywhere stupid so I'm gonna ask EVEN if I forgot'
'point taken…'

WEAPON SHOP

"umm…hellooo"
since no was behind the counter he decided to look around a bit and was impressed at how some of the weapons had markings on them and some were shiny enough to see yourself in them
one katana in particular got his interest
it was about a meter and a half long and looked sharp enough to cut through steel
"you have a good eye for weapons" a female voice came from behind
"ack…sorry" he replied turning around to see a little girl with chocolate brown eyes and her hair done in two buns stand on the chair due to lack of height
"sorry for what?" she said cheerfully
"..nevermind…ummm…do you…sell chakra papers?"
"sure" she said and looked through the drawer
"whatcha gonna do with them?
cuzz as far as I've seen, only jounins come to dad for these"
"i..need it cuzz my sensei told me to go get them for tomorrow's training"
"wow…you must be training to be a real strong person one day"
"YOU BET YOUR ASS I WILL
ONE DAY, NARUTO UZUMAKI WILL BE REMEMBERED AS THE GREATEST NINJA TO HAVE EVER EXISTED" he said in sheer excitement not noticing he was posing with his finger pointing up
'oh the stupidity…what seven year old has a sensei?'
'oh shut up….shit!' he said noticing what he just did and turned bright red since the girl was giggling behind the counter
"okay naruto-san
so how many do you need?"
'fox?'
'two…three should do it'
'MOTHERLOVER!
how many elements do you think I have?
the books said an average ninja has only one elemental affinity'
'I quote….AVERAGE human'
'…good point'
"I'll take three…umm…"
"tenten"
"I'll have three tenten-san"
he took the three and paid for it but there was something he really needed to know
"err…tenten-sa-"
"just ten-chan is fine"
"o-okay…ten-chan…how much is that katana?"
"oh that?
its not for sale
its my dad's pride and joy
he crafted it in a blacksmith tournament and won with it"
"aww…okay
thanks
see you later ten-chan"
"see ya naruto-kun"
'hmhmhm…boy…you realize now you have a hyuuga heiress and probably a master blacksmith's daughter at your disposal right?'
'go fuck yourself…'

BACK IN NARUTO'S PERSONAL TRAINING FIELD

'so…what do I do with these papers?'
'try channeling some of your chakra'
doing as told, naruto transferred some chakra into the paper and it was cut in half
'wind huh?...okay now try transferring some of my chakra into it'
again doing as told, this time the paper was burnt in his hand
'as expected…now…come to the gates so I can show you some wind jutsu I know
though my expertise is in fire so…you'll just have to study books again'

Naruto got into a meditational position and went inside his mindscape

IN FRONT OF THE GATES IN NARUTO'S MINDSCAPE

"so…what?
you gonna show me with your paws?" he said snickering
suddenly a red haired man with slited red eyes in a black cloak came into view behind the bars
"dafuq?"
"this is my human form gaki
how do you think I peeked into womens baths?
you expect a mountain sized fox to go look at womens bath with a friggin grin on his face?
OF COURSE NOT!"
"okay fine…can we get to training now?"
"listen well brat cuzz I'm only gonna say and do it once
this is the tachikaze…or cutting wind"
kyuubi went through a set of handseals before slashing at an imaginary opponent with his claw-like hands and on the pipes appeared what seemed to be wild-animal claw marks
"shit…so I'm gonna need a sharp weapon or I might have to consider growing claws"
"SILENCE FOOL!
DO YOU KNOW HOW MANY WOMEN THESE CLAWS HA-"
Naruto decided to go back to reality and start looking for a weapon instead of listening to him go on and on about his adventures over the years

BACK IN THE WEAPON SHOP

"heloo"
"oh naruto-kun, you're back early…something wrong with the papers?" she asked worried since her dad was away at the moment and she didn't know what to do
"oh no…its just…I need a weapon and I was kinda hoping you'd help me out"
"it'd be my pleasure" she said with a grin
"how about that?" she pointed at a mace twice the size of naruto
"…something I can carry?"
"okay…how about this?" she pointed at a kodachi with a black sheath and red swirl markings on it
'are you fucking kidding me?...its like I'm in a fanfiction and everything's going my way…"
"PERFECT" he said with a grin that made orochimaru think about a face surgery
"I'm glad you like it…no one even notices it…they say the swirl marks make it stupid looking"
and now we have a ready-to-unleash-kyuubi-if-not-for-cute-girl naruto fuming red
"…I'll take it"
and like that, gama-chan, his trusty wallet was done for
"okay…now to get training"
he went to his personal training field and created about a dozen shadown clones
three reading wind jutsu from his library book
six working on the new jutsu with kunais and the last three working on meditation
"still gonna need to fuse completely"
"if i didn't know better...i'd think you want the world gaki"
"you don't say..." and he started training with his kodachi to get used to it
soon enough, with the knowledge from the books and sheer hard work, he learnt how to channel wind chakra through his kodachi and how to throw wind-power enhanced kunais that could tear through a tree but took five seconds for him to concentrate hard enough

Evoila
finished a part of the training and like I said I shall be detailed and yes I AM going to keep my promise of a friggin harem…guhuhuhu….peace out
