Koizumi Junko did not look like a jounin. If she was spotted around Konoha with her neatly cut cinnamon brown bob, hazel eyes leaning more towards green than brown, and slightly timid smile in her uniform it was assumed she was a Chunin. And a young one at that. While in her out of work clothes everyone mistook her for a civilian.

In fact out of her Academy class if her teachers and fellow students had to pick the one students least likely to become a Jounin they would have instantly pointed to the crybaby civilian girl who ran away screaming from a spider and always scored the lowest in spars. But she had, to the amazement of all, made it to Jounin status with her sanity apparently in tact. Or at least most assumed she was the one sane Jounin during small doses of her.

At first glance she seemed startlingly normal. She was surprisingly down to earth and the Mission Room's favorite Jounin always turning her reports in on time, properly formatted, and legible. She was also a favorite among the hospital staff, though they rarely saw her as she listened to their orders and stayed the recommended time with no escape attempts. A record unseen among Konoha's elite. She was unassuming and quite friendly with the civilians and had been one of the few shinobi outside of Umino Iruka to be declared "reasonably sane and normal" by the civilian sector.

It was only over an extended exposure that certain quirks were picked up. For instance she seemed to have an almost phobia of the popular Ichiraku's and refused to set foot there for approximately twelve years. She got twitchy every time someone paid her too much mind and had once ran away when she'd been invited to lunch by a friendly Uchiha Shisui. She also had a strange aversion to apparently random members of the village as a traumatized fruit vendor could attest to as she'd once spent a strange afternoon apparently hiding from Maito Gai. No one could blame her for that though and as she'd went home with a large bag of oranges, the fruit stand owner hadn't been too upset. To top it off she also carried around secret books in which she wrote down ideas for "stories" which were almost as much a curiosity as Copy-Nin's true face. No one had ever actually read any of her work as she was an extremely private person. Shiranui Genma though had caught a glimpse of what appeared to be a strange romance set between two former Genin team members, one of whom betrayed the village and one of whom was dedicated to turning them back. What had stood out was the fact that they were male characters and the fact that Genma had gotten a broken nose for his troubles and the books had apparently been rewritten in code and sealed. Even with these quirks the thing that stood out the most about Junko was a fact that no one else in Konoha was privy to.

Koizumi Junko was in fact the strangest Jounin ever produced by Konoha for the pure virtue of the fact she was currently living her second life with full memories of her first. Junko had originally been born under a name that she believed started with either Ka or Ca, but had fade along with most of her old life over time and in this first life been a slight fan of a manga named Naruto. It was due to this that when Junko had recognized that she'd been reborn into that same manga she'd vowed to live a life of obscurity rather than use what was essential future knowledge to change anything and avoid anyone important at all costs.

Junko had succeeded too right up until the moment her sensei had betrayed her by recommending her for Jounin, leading her to a series of events that would forever make her nineteen year plans for obscurity crash and burn.

"Me? What? No!" Junko said not able to keep the fear out of her voice as she spoke ignoring the curious looks her voice drew. She managed only through years of training not to cringe at the combined weight of so many Character's attention.

The Sandaime looked up at her curiously at the protest. Junko didn't really blame him. She'd never really spoken to him beyond her mission reports and that had always been more her informing the desk of her and her team's missions rather than the man. Even with her distress making her meet his dark searching eyes she only just stopped herself from going back to instant obedience and deference.

"No?" It was a question, but it was loaded with implications.

Junko flushed realizing what exactly she said. She quickly tried to backtrack panicking her, hands worrying the sleeves of her blacks in a way Yusuke-sensei had broken her of after her second Chunin Exams.

"I-I meant surely someone else is better qualified Sandaime-sama!" Junko said eyes flickering around the assembled Jounin who were looking at her as if she'd suddenly started informing everyone how Madara clearly should have really been the First Hokage and then none of the nasty business with his betrayal would have gone down if Tobirama, bless his paranoid heart, hadn't been a grumpy little shit and the world would be infinitely happier. Something that had unfortunately occurred when she'd been fourteen and her teammates had slipped her alcohol without her knowledge. The Uchiha Clan and T&I had side eyed her for weeks afterwards.

She refused to be intimidated because this could not be allowed to happen. "I've only been a Jounin for a year and what's more these students need a special hand and skill set in order to reach their full potential. They'll need access to information I'm incapable of giving them!"

Please Sandaime, think of the children! She thought frantically and her eyes landed on where Hatake Kakashi watched her with his one half-lidded dark grey eye.

"Hatake-san would be much better suited!" Junko continued making the man straighten and his focus turn intense. "He has the parts necessary!"

There were a few snickers from the direction of the newly minted younger Chunin, but Junko refuse to be embarrassed.

"I can hardly teach anyone how to use the Sharingan without having one!" she pleaded turning back towards the Sandaime who sat looking at her impassively. "And he'd be much better equipped to handle Naruto if anything were to go wrong with the seal."

The Sandaime raised an eyebrow at the address and Junko cursed herself. She'd never felt comfortable calling the boy by his surname and she certainly wasn't about to call him the "Kyuubi brat" or any of the less flattering titles her less than reasonable colleagues referred to the child. It was something that made her stand out and therefore avoid talking about the blonde if she could avoid it.

"If I recall correctly you do have some training in using seals." the Sandaime said lightly.

Junko shook her head in denial. "Hardly any worth mentioning. I can make my own tags and storage scrolls, but unlike others I didn't personally study under the Yondaime."

"Maa, now aren't you underestimating yourself Koizumi-san? You know a bit more than the basics. I would say you're actually understanding of the mechanics involved and ability to be creative far exceed mine." a lazy voice said from much too close behind her.

Junko did not whimper but it was a barely repressed thing. She had thus far avoided speaking to any of the Main Characters beyond the demands of mission and social niceties and with Kakashi she can honestly say this would be their first time talking at all.

"I'm sure you're exaggerating." Junko said weakly not turning to look at the Copy-Nin her eyes focused on the Sandaime who was taking this all in.

"I don't exaggerate. I'm sure most people in this room have heard of your performance in the Kiri Chunin Exams and just how proficient you proved yourself to be with seals then."

Junko blanched as she always did when someone that up. The Kiri Exams had not been her finest moment in her hermit life and they'd been a leading reason her traitorous bastard of a sensei had been able to get his recommendation of Jounin status through for her Career Chunin self.

"That doesn't change my argument about the Sharingan." Junko protested. "You are the only one who can hope to teach him when he activates it."

"And I'm sure Kakashi will be more than willing to answer any questions you have and assist you when that does happen." the Sandaime said looking at her now and making her freeze in instinctive obedience, her eyes going wide when she processed the words.

"I realize that as a recently made Jounin and such a young one you may feel unskilled and unsure. But you have been chosen with careful consideration and I fully believe you are the one for this team. I am also sure the older more seasoned Jounin will be willing to help you in the places you feel you lack." the old man continued and the look in his eyes made the last of the rare defiance in Junko burn out and her throat close in panic. "This is my final decision. You, Koizumi Junko are officially the appointed sensei of Team Seven consisting of Haruno Sakura, Uchiha Sasuke, and Uzumaki Naruto. Is this understood?"

Junko felt quailed under the stern eyes and wanted to run away screaming to Kumo, but years of loyal service and obedience to Konoha prevented her from doing more than saying, "Yes, Hokage-sama."

With that the matter settled and the Sandaime continued listing the teams. "Now, Team Eight…"

Junko didn't listen to the rest knowing very well exactly who the Genin would be paired with. She didn't even care about the scene she just caused or the intense disapproving stares of her fellow shinobi. No, Junko's mind was consumed with the knowledge that somehow despite everything she'd done in her life she had managed to somehow mess up the world enough for this to happen. For one of the most important team assignments in history to go wrong.

We're all going to die. She realized with more than a little despair. And then was struck with the thought. I gave up ramen for this?

AUTHOR'S NOTE: So I noticed that the trend in SI/OC's is to begin with their childhood and work your way up, but then I had a thought. A thought that appeared while I should be working on my research paper and the rewrite/planning of Home and Junko was born. A fully adult and pretty "normal" oc-insert who replaces one of Team Seven, but in a far less traditional manner. Junko's background as well as the "why" of the decision behind her placement will be explained later. Much later. I want to say this story will mainly be humor, but honestly I'm bad with genre labels. I don't have any plans for romance though so it's probably not gonna be that unless anyone just really wants to see it or it develops as it goes on. This story is pretty open. I just want to see Team Seven with a normal sensei who's terrified of them and their "destiny".
