(Ok so let me start by saying that someone has brought to my attention that this story needs a lot of work. Which it does, however this chapter is just some simple backstory(that I was planing on doing later, but what ever)on how the plague began. So I hope you all enjoy. Let's get...fuck it)

Thirty days before first infection

Somewhere in an underground bunker, two men stand over the body of a dead ninja. "Edo tensei is one thing sir, but this is just….unlikely" The man on the left said to the man on the right. "Maybe but...I believe I can do it, I can raise the dead...I have to." The man on the right then went through numerous hand signs,then yelled "kinjutsu:Shisha no jutsu." The man's hands started to glow with red chakra, He placed one hand atop the dead man's head, another on his chest. The man on the left watched as the body started to jerk and twitch before it stopped and started to decay. "Damn I thought I had it this time" The man who had just tried to bring the dead to life said in an annoyed tone. "Don't worry sir you will get it, and then you can make this world one step closer to being perfect" the young man smiled to the obviously aged man. "Thank you Yukio that will be all for today,meet me here tomorrow at the same time" the old man smiled at the now revealed Yukio "Yes sir." With that he turned and left leaving the old man to stare at his failure.

Five days before first infection

Yukio entered a dark room looking for the lead researcher at the facility the mans name was unknown to all except yukio. The mans name was Nobu Izanami and he was,in fact , sitting in the dark room studying something or someone. "Sir wh-what are you doing in here" the young man said,the older man turned to look at him with a smile. "Im so close yukio come,come look" the man waved to walked to the man in the corner closing the door behind him "what have you discovered sir" he asked the smiling man sat up and struck a match lighting up his cigar "look in the corner chained to the wall" yukio looked and saw a man chained to the wall in the darkness. Yukio's eyes widened in surprise 'has he finally done it' he thought to himself "so is it complete." The man sighed "unfortunately no it will only turn the subject into a zombified corpse,but i'm so close i can taste it,do you know what this means my boy?" The old man questioned, Yukio however only shook his head "well it means i should be able to perfect my jutsu by the end of the month." Yukio smiled 'good the faster you finish the faster i can kill all these lunatics,grab you, and go home,i wonder if that silver haired bastard is still reading those damned books' he went back to his serious tone and said "well i just came to ask if you needed anything." The old man smiled and handed Yukio a stack of papers "these are to go to the research bay for umm….disease weaponization " the man said sweatdropped "can i ask why sir" the man chuckled "well it seems i have created a new disease."

Day of first infection

Yukio ran down a big hall with sirens indicating that there was a facility wide evacuation,he was looking for the door marked with a caution sign. He finally came to his destination and quickly opened the door "sir are you in here!" he yelled over the sirens,no answer. Yukio continued running down the hall that was quickly filling with people running the opposite way he scanned the faces of all the older men he passed,none of which were his target 'damn where could this guy be' he thought to himself as he entered the scientist's office. "sir you in here!" he called out,no answer,he started to walk out but his trained ears heard "yukio i-is that you." Yukio rushed over to the sound,what he found will haunt his dreams forever,the man was missing his arm and the lower half off his body. Yukio was surprised that the man was still alive "what happened to you" yukio said trying not to puke "wel-l it seems th-that disease i cre-cough-ated made the people…"he breathed in deeply "very violent and the-y ea-ea-eat other people."

Yukio started at the dying man for several minutes before the man spoke again "look m-my boy,take this" he handed Yukio a scroll "it contains all of my research on not only the only the jutsu but also the research on the disease that i caused." Yukio started to try and pick up the old man saying "you will make it old man,i'm not leaving you here,i'll use the jutsu to bring you back" the man grunted in pain then grabbed Yukio and smiled."It wouldn't work son,you ne-ed the perso-ns body intact….its not per...fec...t."The man known as Nobu Izanami died in Yukio's arms. Yukio let the tears he had been holding back flow 'i know this was a mission but he didn't deserve this...he should have come with me.' Yukio laid the man he had been ready to call his surrogate father down and turned to leave,he still had a mission to complete.'im sorry i didn't get here soon enough old man' he thought as he drew his sword and stepped into the were still gathering data and running to the exit, Yukio started a slow jog down the hall swinging his sword as he passed hated this part,he knew it would eventually come to this but he couldn't help but remember four years ago when jiraiya had given him this mission.

Flashback:Five years ago

Location:Small settlement outside Konoha

"You summoned me jiraiya-Sama" came the voice of a young Yukio "As a matter of fact i did yukio for two reasons." Yukio bowed "what is it you need sir" jiraiya smiled "Well first off i am going to be training my newest student ,one Naruto Uzumaki, for a while so i wont be back for at least three years." Yukio's eyes became the size of dinner plates at that "but..but i'm suppose to be your next student" the boy sighed "i know yukio but this boy is in far more need than you,and it's kind of a promise to someone" yukio pouted "then i say i fight him for the right to call you sensei." jiraiya just scoffed "he would be destroyed,you may not be as powerful as him but you are way over his skill level" yukio smiled "then that settles it i'm the one you should teach not him." Jiraiya facepalmed "listen when i get back your training begins ok" the boy perked up "ok...what was the other thing you wanted to speak to me about." Jiraiya handed him a brown envelope "your next mission...it should keep you busy while i'm gone" Yukio was about to speak when a voice from outside beat him to it. "Pervy-Sage come on i'm ready to do some training believe it!" Jiraiya sucked his teeth "i hate that catch phrase of his...well good bye yukio."With that the white haired man turned and left,yukio following him until he was outside. Yukio peeked out the door just in time to see Jiraiya leave with a boy his age with blonde hair,blue shinobi sandals,and in a clad orange tracksuit.

End flashback

Yukio walked out of the building that was now burning,sword in one hand,and a small girl in the had found her in the building apparently she was one of the test subjects,the girl was around 13 years old. She had crimson red hair and bright green eyes."what's your name" Yukio asked her "my-my name i-is Mina...what's yours" he smiled "my name is yukio"

-Two days later-

Mina and Yukio were about to be within visual range of the village hidden in the leaves,when Mina asked Yukio "so umm...why do you wear that band around your eyes...if you don't mind me asking." He smiled and reached for the band that covered his eyes "because of my kekkei genkai….it activated while i was in the facility" Mina's eyes widened "really." Yukio laughed "really...as a matter of fact they wanted to experiment on me" his smile faded and turned into a pain filled frown "they would have if not for the old man." Yukio looked off into the distance recalling the events of that day

Flashback:Two Years Ago

Yukio awoke in a cold sweat he opened his eyes and everything was glowing white "what the hell" he sat looked at his clock "its…..i cant see it" he just sat there for a moment until it hit him. "I cant fuckin see!" he shouted waking up the man in the bed to his left "Yukio what's wrong" the man ran up to yukio. "I can't see ….i can't see" the man got dressed and took Yukio to the doctors who were there 24/7 "so yukio what happened." Yukio sighed "Like i said i woke up and couldn't see anything….but now i'm slowly seeing shapes of people" the doctor got a confused look."Your eyes, what color are your eyes yukio" Yukio got a confused look "my eyes are green duh can't you see them"the doctor laughed awkwardly "well i do and can but umm….they are not green, your sclerae are pitch black and your irises are a silver color." Yukios eyes almost popped out of his sockets "wh-what the hell"

Two days later

Yukio sat in a lab with a young woman who was in a lab coat. "So Yukio what can you see"Yukio sighed "same as yesterday miss shu only chakra in living things and the vibration coming off non living things." the woman sighed "well at least i've made the discovery of a new doujutsu...ummm you don't mind if i name it do you" Yukio smiled "not at all miss" she grabbed his hand and smiled "thanks." After a few more hours another scientist walked in with a young man and young girl around 14 and 15."Hello yukio i have come to examine this new doujutsu of yours,this is sakae uchiha and himaru hyuga" the pair said hello, himaru walked up to Yukio and activated his byakugan and looked into his eyes. What happened next had everyone staring in amazement,his eyes imitated the byakugan but was black instead of white. "is that even possible" the male scientist said and pushed sakae in front of yukio,she activated her sharingan and his eyes changed 's eyes mimicked the sharingan only it was a silver color. "well i have a name for it now if that's still ok...Subete no mōdōken,the all seeing eye."
