A/N: My first story on Naruto. Have never done it before, so sorry if it's not for your liking.

I am aware that stories containing OC are not always received nicely by the readers, but I couldn't help myself. It's just that I don't really find any female character in Naruto that would fit nicely with Kakashi (sorry to any fans of KakaSaku, TsunaKaka and KakaRin). That's why I decided to put OC in this story. And I'm sorry if she is not to your liking.

Anyway, I hope that you will like it.

Disclaimer: I don't own anything, aside of Team Kushina.

She really didn't want to do this.

Being a jounin teacher was fun and all, as she heard, but it wasn't her cup of tea. No, Uzumaki Kushina definitely preferred to be send on a high-ranked missions and risk being hurt, dismembered, impaled, dead and even castrated (theoretically not possible in her case, but well… nothing is impossible to a willing mind, right?). Everything but babysitting three kids with different levels of talent and skills. She had problem with taking care of herself sometimes, who even would think that she was able to take care of three young innocent souls? Definitely bad idea.

For a quite long moment she had been thinking about dropping the three brats that were assigned to her on her sunshine-blond boyfriend. He had already three of his own, so another three wouldn't hurt him, right? He was a prodigy after all, so he would handle them. But the Sandaime Hokage seemed to know her better than she thought since he had prohibited her to ditch the three young genins on anyone, especially not on Namikaze Minato (maybe because the blond would not be able to refuse any of her pleas). Even before she had said anything, dammit! That wasn't fair.

But still, she was there, standing in front of three young masochistic souls given into her own sadistic hands. What was she supposed to do? She had no idea how to start the first lesson.

Now, every other person in the world, after being assigned a new team of genins, would prepare something before-hand. But not Kushina. She preferred to go all night with her ladies friends and come back to home at dawn, go back to sleep and almost be late on the meeting if not for her botfriend who had dragged her hang over body on the training ground. But she wasn't late. She was just in time. She was just that awesome.

They were looking at her. For, like, five minutes now. And she was looking back at them. Also for five minutes now.

"So… yeah… I'm Uzumaki Kushina and I will be your jounin teacher starting now." She said, wondering if it wasn't too late to assign to ANBU. They were not being assigned any teams of children, right?

Don't blame her, the kids were scary in their own way.

"Let's start with introducing ourselves, 'ttebane!" she decided.

Knowing their names would be good. She still need to find the files given to her by the Hokage. They were in her apartment… somewhere.

"Akiyama Natsuki."

Looks like someone had a fetish on seasons. Kushina examined the girl with brown hair and green eyes in front of her while the girl looked at her with interest. When she didn't see anything interesting in the young kunoichi, she moved her eyes onto a first boy.

"Yukimura Isamu."

Well, if the dark haired kid stand up to his name Kushina could see a great bond forming between them. And no, she wasn't playing favorites. But seeing the confidence in his brown eyes, the redhead decided that she may found the star of the team.

"Yamauchi Saburo."

The boy with shy blue eyes looked at her for a short moment before averting his gaze. Kushina decided that they would first work on his self-esteem.

"Great. Now that we know each other…" more or less, she thought "… we can see what you can do, 'ttebane! Any questions?"

She looked again at the girl when she raised her hand.

"What does "'ttebane" means?"

After the first month of being a jounin teacher Kushina learned few things:

1. Don't let Isamu anywhere near sweet things- When Kushina stopped only for a short moment to ask something Uchiha Mikoto who was just passing by, the boy had gone mysteriously missing. It had taken her ten minutes to drag him out of the near shop. And by dragging him out she actually meant throwing him over her shoulder and carrying him away from the shop.

2. Be careful what you are saying. Because when you say to 'go all out', the kids can actually do it and drain themselves out of chakra to the point where they faint. And send themselves to the hospital on the first day. She was still getting a stingy eye from the medic nins.

3. Her team was definitely suicidal. They were not innocent children. They were devils sent to make her live a hell by blaming their deaths on her: Saburo nearly impaled himself with his own kunai, Isamu decided that telling her a new joke about an Uchiha while one of them were passing by was a good idea and Natsuki blindly went in between two fighting shinobis, who just had to happen to be Minato and Jiraya (thanks Kami for quick reflexes of the two) on the training ground.

After another meeting with the three of them and the first D mission after they got used to each other… to some point…. Kushina came back home completely exhausted and drained psychically. Their mission was simple: help the local inn keeper in running the inn for a week during which the owner's daughters are on vacation. Everything was going nicely. At the beginning. Everything went down from there. In the end they had to pay back for destroyed property and bills from mental center.

To say it mildly, Hokage wasn't happy with them.

She had to think about something to keep them out of trouble for the time being, until the anger of the Old Man die a little bit. But how to do that?

"'Shina-sensei!" the voice of one of the three biggest problems in her life was heard and she turned around to face the kids. "When are we going on another mission?"

Kushina smiled widely at kids while thinking very hard of what to say to them. 'Sorry kids, you pissed the Old Man so we are staying down for a while?' It would not go well.

Think, Kushina, think…

"Sensei, are you ok?" Natsuki asked her suddenly, backing just a little with worried look. Seriously, the concentrated look on the face of her teacher with the addition of creepy smile was just… threatening.

Kushina was about to admit her defeat when in the corner of her eye she, caught a sight of Minato and his team. She smiled even wider in victory while Natsuki took one step back again. This time her teammates did the same, just in case.

"Well, we have a mission now, 'ttebane!" she announced loudly, catching the attention of few people around.

While Isamu looked at her eagerly, Saburo and Natsuki wandered what they had ever done to get a teacher like that. Because whatever Kushina-sensei had in her head was seriously going to have them killed. The gleam in her eyes told them so.

"W-What is this mission, sensei?" Saburo dared to asked and Kushina remembered that they were going to work on his self-esteem.

"See they white haired little guy over there with Minato?" she asked pointing her finger.

Of course they knew Minato, after all he was the one who had dragged back their sensei on the meetings when she was fed up with them.

"You mean Hatake Kakashi?" Isamu asked, putting his hands to his pockets and turning his head back to the redhead.

Kushina nodded her head, getting more and more pleased with herself.

"Your mission, my three little students, is to make him take off his mask, 'ttebane!" she announced once again and her students again decided that the happy and overly pleased with herself tone of voice was terrifying.

"What for?"

Kushina blinked at Natsuki.

"What do you mean 'what for'?" she answered with a question.

"I mean, mission usually had some reasons why we are accomplishing them, right, Kushina-sensei?" Natsuki blinked her eyes at her innocently, but the redhead could swear that she could see the evil glint somewhere in the back of the green pools. "What are we going to accomplish by making Hatake taking his mask off?"

"Getting off Hokage's way for some time is good enough reason." She thought.

"It's a way for me to see how stealth, sneaky and intelligent are you, guys." She said aloud.

Kakashi could be a chibi in her opinion, but the kid was freaking prodigy after all and even she had to acknowledge his abilities. Her three little genins stood no chance against soon-to-be jonin.

Yeah, she was a terrible teacher.

"So, all we have to do make him take it off?" Saburo asked.

She nodded her head.

"That's all?" Isamu looked at her questioningly,

She nodded again.

"Is it really a mission?" Natsuki looked at her still suspicious.

She nodded again.

The three of them looked again in the direction of the white haired boy.

Kushina sighed with relief when they all nodded their head. She had few weeks of quiet and peace. There was no way they would be able to do it. After all, she had been trying to take Kakashi's mask off for three years already and hadn't succeeded.

Kakashi suddenly felt a chill running down his neck and she knew that something bad was going to happen to him,

"Something wrong, Kakashi?" Minato asked, noticing suddenly alarmed look on the boy's face.

"No, sensei, everything is fine." He answered while looking around.

Nothing seemed out of place. More importantly, he hadn't noticed green spandex anywhere. But then his eyes caught the sight of red hair whose owner was suspiciously pointing her finger at him with three kids nodding their heads with different level of eagerness.

"Minato-sensei?"

"What is it, Kakashi?" the blond asked, furrowing his brows at the little boy. Something seemed really wrong with his student.

"I think Kushina-sensei is planning to kill me again." He answered not taking his eyes from the said kunoichi.

"Kakashi, Kushina had never tried to kill you." Minato answered calmly Well, maybe she almost choked the kid with his own mask while trying to take it off, but… well, he had no excuse for her.

But he turned his eyes in the direction of where Kakashi was looking and a small sweatdrop formed on his forehead. Kakashi was right, the look on her face was telling troubles. And he knew he was going to get caught in between. Especially when her three students were staring at Kakashi with some strange calculating look.

"What were you saying, sensei?" Kakashi with raised brow.

Kakashi's life had turned into a pit of mental tortures. His next week looked as follows:

Day #1

Of course Kakashi knew that someone was following him just an hour after Kushina-sensei and her team disappeared from his sight.

The three morons didn't even try to hide their chakra signatures.

Well, at first he had no idea who was following him, but a window was a great shinobi tool too.

So when the back haired guy tried to jump on him from behind and made an attempt to grab his face, he simply shoved the idiot to the ground and left him to be picked up by the rest of the trio.

Day #2

Kakashi felt his eyebrow ticking nervously when he passed a 'newly opened' stand offering different styles of face mask.

It goes without saying that the three of Kushina-sensei's idiots could go better with simple henge that some crazy attires, most probably provided to them by the redhead herself.

Day #3

He knew even before he had entered his apartment that the idiots were already there.

So he was not even surprised by the three plants standing in his living room, one with foot sticking out from the pot and the other with blue eyes blinking shyly on him from a leaf.

Well, at least they used henge this time.

And Kakashi was reminded why he preferred plants from people when he was throwing the trio out of his apartment: they were silent.

Day #4

Kakashi was thinking about seriously killing them when he came back from a mission and heard some strange noises coming from his closet. He made his way there, but was stopped by the slight chakra change of one of them.

"Isamu, did you just touch my butt?"

There was a moment of silence followed by nervous laugh.

"W-Wait, Natsu-san, I'm here t-too!"

He left his apartment, deciding that at least two of them were getting their punishment.

Day #5 and #6

He thought that after he had put a better barrier around his bathroom after Gai invited himself there, no one would be able to enter there.

But he was wrong.

He had two uninvited guests two days straight.

Day #7

Kakashi knew that he was going to have free day when he overheard their conversation.

"No."

"But Natsu, we had already done it!"

"So?"

"Now is your turn."

"I'm not going to sneak into his bathtub, Isamu, forget it."

"Why not?"

"Maybe because I'm a girl, idiot?"

"Exactly! There is a chance that he won't throw you out!"

Kakashi gracefully stepped out of the way when a lifeless body flew by him.

Day #8

Kakashi had never felt so mentally scarred for life.

Because being pushed by the cross-dressed student of your sensei's girlfriends, a boy around his age in definitely not fitting red dress and heels and make-up, who was trying to pull down your mask to kiss you while acting as some drama queen was an event that would imprint in his memory forever.

It was his breaking point. He needed to know why they were pushing his limits and making idiots out of themselves.

Maybe he was influenced by their idiocy or his lack of sleep or something, but suddenly the idea of kidnapping one of them was quite an attractive idea.

So, he had to make a plan.

First was to decide who would be the first to break.

Isamu, the guy who seemed to be the chairman of the idiocy, seemed to be at the same level of stubbornness and stupidness as Obito, so trying to interrogate him was fruitless. He didn't feel like dealing with second Uchiha now.

Saburo was ready to faint at the spot when the white haired boy just passed him on the street or something. Kakashi was actually scared that the guy would die from shock or a heart attack.

So it left him with only one choice- Natsuki.

Well, it wasn't really a kidnapping per say. He just dragged her out of her apartment by her collar, excusing her mother who looked just slightly amused by the situation and completely trying to ignore the black cat who was doing everything to trip him.

She was smart enough to not fighting back.

"If I say it was for greater good will it help me?" she asked and he glared at her.

In her books this excuse worked wonders usually.

"Ok, I get it." She added when he didn't answer. "But you can let me go, I promise I won't run."

"You think you would have a chance to run?" he asked coldly but let go of her collar nevertheless.

"Probably not."

"Surely not." He corrected her and looked at her with crossed arms. "Now talk."

When for the first time in months when Minato had the three of them under his care it was Kakashi who was late, not Obito, he became quite worried.

And when Kushina suddenly appeared sheepish on the training ground with two of her students, one looking uneasy and the other ready to drop dead at any moment, he became very worried.

"What happened?" he asked while Rin looked over the sickly looking boy.

"You see… I can't find Natsu anywhere and she had been last seen by her mother with Kakashi who literally dragged her out of her apartment, 'ttebane." She explained, and Minato noticed with a little surprise that there was worry in her eyes.

He furrowed his brow. It was definitely out of character for Kakashi to do something like that… unless he was pushed to his limits.

"Kushina…" he moaned. "What did you do?"

"Why are you assuming that I have done anything, 'ttebane?!" she shouted at him offended.

Five pointed looks caused her to calm down.

Taking a deep breath she told him about her team's 'mission'.

"… you are sadistic." Minato commented, slapping his forehead.

"Kushina- sensei, that's awesome! Why didn't you tell me, I would help!" Obito shouted, looking at the redhead with stars in his eyes.

Everything that pissed Kakashi off was like an aphrodisiac to him.

"No, you wouldn't. That's mean, Obito!" Rin lectured him, putting her hands on her hips.

"Ok, now we need to find Kakashi and Natsu."

Minato had no idea where it came from, but had sudden image of Kakashi in little devil's dress with pitchfork which he used to pock with evil grin the tied up and crying Natsuki.

Too much time with Kushina, definitely.

"I'm here."

Kushina turned around as quickly as possible and was at Natsu's side in the blink of eye, faster than the Yellow Flash would ever be. Well, not really.

"Are you okay?! He didn't hurt you, did he, 'ttebane?!" she started to look her over, ignoring the scared look on her female student's face on her actions and glaring at the white haired boy who entered after her.

"Y-yeah, I'm f-fine, sensei." She answered and backed a little. "Anyway, I completed your mission." She added, handing over the dark mask in her hand to the older female.

There was a long silence in the room. They all looked first at Kakashi who nodded his head with another mask on already.

"How?!"

"Wait, have you seen his face?!"

"N-Natsu-san, I thought he was going to kill you! What d-did he do to you?!"

"What the hell were you thinking, 'ttebane?!"

Natsuki blinked, just slightly terrified by Kushina's, Obito's, Saburo's and Isamu's faces shouting questions at her.

She smiled however, raising her finger.

"It's…"

They went quiet and waited.

"… a secret."

Minato only smiled at the look on his girlfriend's face.

"Oi… just what kind of monster do you think I am?" Kakashi asked with ticking eyebrow.

Now he needed to stop his student from having revenge.

Two silhouettes were visible standing in front of the memorial stones in the dark night, tracing with their eyes names of their once important people.

Uzumaki Kushina

Namikaze Minato

Uchiha Obito

Nohara Rin

Yukimura Isamu

After some time, they went in two separate directions. No goodbyes were needed, they were not so close to each other anyway to play in some emotional way of parting and it was probably the last time they had seen each other anyway.
