A/N: I notice there wasn't any fic about an Adult Reborn and a female Naruto so I decided to create one so please tell me what you think.

If there was one teacher Tsuna knew he could always count on his back, it was Uzumaki Naru.

Out of all the teachers in the school, only Uzumaki-san never called him Dame-Tsuna and always scolded the students that bullied him, giving them lectures about how in the real world he could be the one to boss them around and not the other way. Everyone in their class knew that would never happen, he knew it would never happen but whenever his sensei said that, he couldn't help but think that maybe she was right. That was why he never tried to skip math lessons with her. It didn't help she really was pretty and was just so young to be a teacher.

Still Uzumaki Naru was a complete mystery to everyone in their school, no to their whole town.

No one in the school knew her age but everyone guessed she had to be around her early twenties because no way a thirty year old woman could look as young as she did right? No one in the school knew where she was before she came to Namimori Middle School or even her own history. Some people say she used to be a part of the Yakuza while other people say that she came to this school to avoid a powerful man that wanted her. A few people even say she wasn't human but a fairy, though Tsuna highly doubt the last bit.

He sighed as he placed his stuff into his bag. It didn't matter though, he thought to himself, because no matter how nice his sensei was she wasn't enough for him to want to stay in school with the knowledge that Kyoko was going out with someone else. It was stupid of him to be upset since he never asked her out but to know she was dating his bully was breaking his heart. Surely, his sensei would be okay with him not being in school after all he was usually in school most of the time.

"Tsuna, where do you think you're going?" He blinked, twisted his body around and squealed at the sight of his sensei standing right behind him with her hands crossed. "Last time I check, school isn't over...and you have a lesson right now don't you?"

He didn't answer her, flickering his eyes at his bag and then to her before fixing his eyes at his books. He didn't want to see her expression, didn't want her to give her those looks that everyone else always gave him. It wasn't bad when everyone else gave it to him, he had accepted it but for some reason whenever this sensei gave him the disappointed look, he felt compelled to do what she want.

She sighed. "Was I this bad when I was kid? Tsuna, come to my office."

"How much trouble am I in?"

"I'll decide how much trouble you're in when you tell me why you're trying to skip school," she retorted, grabbing him by the arm as she led him to his office, "You think I'm one of those teachers who will scold you for skipping school? I was a student once and I know people skip lessons for a lot of reasons, some of them can be a good reason. So tell me yours and I'll see if you get a detention or worse."

"You u-used to skip school?"

His sensei laughed. "Of course I did, do you think I'm an angel or something?"

He flushed red, shyly nodded his head and watched as his sensei smiled gently at him. It was the first time his sensei ever gave a gentle smile. Most of the time the blond-haired woman would just give them a big smile, showing everyone her teeth. This smile, Tsuna decided, he liked more than her big smiles because it somehow screamed more warmth to him.

"You're the first person I know who actually thought I was an angel," she opened the door to the office and gestured for him to take a seat in front of him, "I wasn't an angel in school if you asked my teacher, I was one of his worst troublemakers. He used to search for me whenever I skipped lessons and when he did find me, he would drag me by the ear and scold me for being an idiot for skipping lessons."

"Y-You don't look like a troublemaker."

"Look underneath the underneath," his sensei said, opening a can of biscuits. She offered him the big chocolate chip cookie. He took one and nibble at it, wondering how his sensei knew just what he liked. "One of my teachers told me that when I was young. Anyways, this isn't about me...this is about you. Why were you trying to skip school, Tsuna?"

"You'll think I'm stupid."

She raised her eyebrows at him. "Let me decide that, now why were you trying to skip school?"

"It was because of the girl I like."

"Sasagawa-san right?" He blinked his eyes at his sensei, who had a smile on her face. "Even the most oblivious idiot can tell that you like her. So what did she do to make you want to skip school? Not even my best friend who liked her husband for a really long time would have done what you did and she was just like you...so what happened?"

He licked his dried lips. "She's dating Mochida-senpai. I-I can't go to school if she's dating him."

Only this teacher made him want to confess these things to her, Tsuna thought, crossing his hands together as he waited for his sensei to scold him for it. She gave him a sad smile, glanced at the photo in her table but made no attempts to say anything immediately to him. He was glad for that. Tsuna allowed his eyes to wander around the room, noting how the room was filled with more scrolls than books and how there were few pictures decorating her office. The only picture that stood out to him was the picture of his sensei with a pink-haired girl, a dark-haired boy and a silver-haired man.

"Did you tell her how you feel about her?" He hesitated and shook his head. "Then you've no right to feel upset about her dating someone else. Despite what people think, girls aren't mind readers. We don't know what a man feels about us without them telling us. If you asked her out then maybe she wouldn't go out with Mochida. Even if she said no, it'll be her lost because you Tsuna are the type of a boy any girl with common sense date. You know when you get older, you'll find a girl that's better than Sasagawa, so that's why you should never let her be the reason for you coming to school...trust me when I say that it'll hurt you more in the long run."

"Sensei, did you used to go to school because of a boy?"

She smiled and laughed. "Do I look like the kind of a woman who would go to school because of a guy? I was the girl who could care less about what a guy thinks of her...no I went to school because I wanted to be somebody."

"But you're teacher."

"Who says I'm not somebody?" His teacher asked, taking a bite of the cookie. "Maybe I became a teacher because I like teaching kids like you or maybe I'm trying to get away from something."

"T-Those rumors were true?"

"What rumors?"

He hesitated. "Uzumaki-sensei, people say that you came here because a powerful man wanted you."

"No, I didn't come here because of a man," she answered, taking another nibble of her cookie. "But maybe I'm trying to get away from something. If you get straight A's in your Math Test, I'll tell you the real reason why I came to this town."

"...You're never going to tell me are you?"

She grinned. "I know you can get straight A's in your Math test, after all you're one of my best students."

His heart warmed at her words. Perhaps, he was an idiot for trying to skip school for a girl and going home to his mother, who would never ever say as many nice things as this sensei did. He nodded his head furiously at her, gave her a small bow before rushing off to his last lesson of the day. If this sensei of his believe in him then he wanted to know why this nice woman came to their school instead of doing something more worthwhile.

Not once did he notice that a dark-haired man was watching him.

Releasing her hair from her hair tie, Naru relaxed her shoulders as she grabbed her bag from under the table and grabbed the bunch of test papers from the students. Her hands hovered when she caught sight of the picture of her old team. Had it really been nearly four years since she left home? She should go back home soon but she didn't feel ready just yet to confront her friends. Besides, she still send them letters and it seemed like everyone was fine over there.

She smiled and hummed a small tune to herself as she walked out of the gates of the school. Maybe she would go back home when Tsuna was fine. Out of all the students she had taught, she felt the most connection with the nervous boy. When he was able to graduate from school, Naru decided she would go back home and reconnect with her friends. After all, she needed to visit the godson that Hinata had given birth to and god knew Shikamaru needed help in confessing his love to Temari.

She was broken out of her thoughts when she found herself colliding with something hard. Rubbing her forehead, Naru blinked her eyes at the sight of a tall man standing in front of her. He wasn't from around here, she thought, gazing at the man's orange band fedora's hat. She had been here for nearly four years now and not once had she ever met a man with his hat or those curly sideburns.

"Sorry about that," she said, pushing herself off the man. He nodded and kneeled down to the ground, where the piles of test papers were thrown carelessly down to the ground. She groaned. Why must it happen today of all days? This was the one day where she didn't have to overlook activities or have any lessons in the afternoon. She just wanted to go to the apartment for once and relax before making her way through the piles of paper. God, she wanted to apologize to her sensei for not being the best student to him.

"So which subject do you teach?"

She blinked. "Maths...and how do you know I was a teacher?"

He just smirked, flickered his eyes at the test paper as if to tell her that was how he knew...and oh god did she feel more like an idiot for not realizing that. Right, think before you talk. She told herself, stuffing the test papers into her bags. She didn't want anyone else to think she was an idiot, kami knew she already had her old teammates thinking she was an idiot. Now, she didn't want a stranger to think she was one too.

"How long have you been working here?"

"Nearly four years now," she answered him as he handed her the final test paper to her, "Next month will be my fourth year that I taught in this school. So what brings you here near the end of the school day?"

He shrugged. "I was here for a walk."

Liar, her mind whispered to her as she stared into his amused dark eyes, he wasn't here for walk. He also certainly didn't look like he was here for a walk after all how many people she knew took binoculars in their walks? It certainly was worrying especially since her own experience with her own teachers made her think that anyone with binoculars was doing 'research'. Thank god, she could use her own imagination instead of doing 'research' like that perverted Ero-sennin did.

"What kind of a walk must you do for you to carry binoculars?" she asked, slinging her bag over her shoulder. "I don't take you as the kind of guy who does bird watching."

"Maybe I'm that type of guy you know what they say, never judge a book by its cover," he said, placing his binoculars into his pockets. "And I don't pick you as a woman who is meant for teaching, Uzumaki Naru."

She blinked, opened her mouth before closing it as the man brushed her off, leaving her alone in the streets as the school bell rang to signal the end of the school day. How did he know her name? Licking her dried lips, she placed her hand into her pockets, while her other hand hesitantly touched the headband wrapped around her waist. The man knew, she thought to herself, taking in deep breaths as she walked towards her apartment complex.

The man must have some idea about her other job.

His student's math teacher, Reborn decided as he entered his student's house, had to be one of the most interesting woman he had the pleasure of observing. She looked relatively harmless with her short stature and big blue eyes but he knew from the tones in her arm's muscle as well as from her weariness, the woman wasn't some civilian woman. It made him interested to know what a woman like her was doing working in a school like Namimori and not out there doing another kind of job.

He stopped walking when he reached the top of the stairs, where the sounds of his new student and his mother's voices could be heard. Placing his hands into his pockets, Reborn slip into his student's room, where he could clearly see piles of manga were thrown carelessly in the ground.

"A HOME TUTOR?" His student yelled. "Kaa-chan, I'm doing alright in Math."

"And I'm proud of you but there's more to school then Math," his mother said, holding out his math paper which had a doddle of said math teacher. "But you've to pick up on your subjects! You need to do well in your other subjects too. I'm not saying you've to go to a good school but it would nice for you to have just as good as grades as you do for Math."

"And you thought to hire a home tutor?"

"Yes," the woman answered, waving his flyer at him. "There was an interesting flyer was in our guy in the flyer claimed he would raise any kid to be the new leader of the next generation and the best part Tsun-kun? He doesn't care about grades or subject. His name is Reborn."

The boy eyed the flyer with weariness. "It smells like a scam."

Not dumb, Reborn thought to himself, leaning against the wall. He didn't look slow, a little bit clumsy maybe and from the piles of manga in the room, he could tell the boy was a slacker. That wasn't any good but he could fix that. It wouldn't do any good to anyone if it turned out the boss of the Vongola family was a slacker. No one would take him seriously nor would anyone take his tutoring seriously. Perhaps, after trying the dying will bullet on the boy, he would force the boy to tidy his room.

God knew he wasn't going to stay in a pig sty for the next couple of years.

"He's probably a tutor from a professional business school for young man," The boy's mother clapped her hands together in excitement as she continued to babble, "I've always wanted a teacher like that for you."

"Don't create your own image of him," Tsuna snapped. "And I don't need a tutor. Besides Math, I'm not good in anything that I do."

That was his signal for him to make his presence known.

"Chaos," he stepped between the mother and son, surveying the nervous boy and then to the posters around the wall before finally looking at the shelf, where he could see a clear lack of picture of friends. He knew from watching the boy for the past three hours, the boy didn't have any friends but this confirmed it. That explained why he didn't have any problems talking to his math teacher. "I arrived three hours early but as a service, I'll evaluate you now."

"Who are you?" The woman, Nana, asked, staring up at him.

He let his lips curled into a smirk. "Me? I'm Reborn, the home tutor."

His smirk widened when the woman clapped her hands, looked up and down at him before proclaiming to her son about how he was exactly how she thought he would be. Would she still say those things if she knew his real occupation? Looking at the oblivious smile on her face, he doubt the woman would really care. It was a wonder how a woman like her married a man like Iemitsu without figuring the truth so far. It's reasons like those, he tried to avoid dating woman like Iemitsu's wife.

Nana seemed like a wonderful woman, too good for Iemitsu, but either way she was too naïve for his taste.

Tsuna just stared, looking at his hat and then to his face, before bursting out in laughter. "I don't know what I can learn from you...you don't look that much older then me."

Reborn's eyes twitched at his words. Not much older then him? It was true he was still stuck looking like he was in his early twenties but he did know a hell lot moree things. Also didn't anyone taught the boy to respect his elders? Guess that was just one more thing he needed to teach him. With that thought in his mind, he kicked the boy in the stomach and watched as he slumped down to the ground.

Iemitsu and Nono never told him he couldn't hit the boy...and he needed a release for his pent up anger.

"Well we're going to get started."

"How the hell did I forget to stock up on food?" Naru asked herself as she tied the headband around her forehead. She finished marking all those papers, with the help of her clones of course, when she decided to cook her favorite food only to find there was nothing in the fridge. Had it really been a week since she last stock up on food? Maybe she should follow her student's advice and just put a reminder on her phone about going to the grocery store more often.

"You gotta be kidding me! You're actually following me! I thought you already ate," A familiar voice yelled.

Naru blinked her eyes when she caught sight of her student walking in front of the same man that was in front of the school earlier. How did he know this man? Oh god, don't tell her that this man was his father? No, he looked too young to be a father to a twelve year old. He looked like he was nearly the same age to her, maybe a year or two older but still too young to be a father.

Maybe, they were brothers.

"Uzumaki-sensei, why are you here?" Tsuna asked when he finally noticed her.

She shrugged. "I was going to the grocery store. What about you? And what did that man do for you to yell at him?"

"What makes you think I did anything to him?"The man asked, giving her a smirk.

"Because Tsuna never yells," she answered, rolling her eyes at him. "And it sounded like you're bullying the kid for food when you already ate."

"Sensei..."

"Don't give me that look kid," Naru said, ruffling the boy's hair. "I thought I always told you to smile."

"Y-You did," Tsuna stuttered.

She frowned at his flushed face, glanced at the man, who just looked at her and then to Tsuna with amusement. What the hell was so funny? Her student's face was just as red as a tomato. What if he was sick with a fever? Didn't his mother check on her son before he left the house? She might need to go and check on his mother to see if everything was fine. It wasn't easy for the woman to try and take care of a household by herself without any help.

She shook her head and frowned when Tsuna slumped his shoulders at her. She raised her eyebrow when the younger boy turned his body to the next corner, squeaked and rush towards the other corner of the street. Scratching her head, Naru glanced at the man, who looked just as confused as her. She glanced at her student and gestured for him to come out but he furiously shook his head at her.

Was she as bad as Tsuna when she was a kid?

"Uzumaki-sensei!" Naru blinked and smiled when Kyoko rushed towards her with a big smile on her face. "I didn't know you lived around here."

"I don't but the best grocery store for my needs is just around the corner," she explained and frowned when she caught sight of her student wearing her school uniform. "Why are you still in uniform? It's six now."

"Mochida-senpai said he needed to talk to me about a couple of things for the council," Kyoko answered, giving her a small smile. The young girl blinked her eyes when she caught sight of Reborn standing beside her and oh god, why did she have a bad feeling about the twinkle in her eyes? "Are you on a date, sensei? Is that why he is dressed so nicely?"

Yup, she was right to have a bad feeling.

"No!" She scowled at the idea of having a man like Reborn as her boyfriend while said man just looked deeply amused at what the girl had just said. "I just met the man Kyoko-chan. Besides, can you imagine a woman like me dating a man that looks prettier than me?"

She laughed and nodded. "You'll look good together sensei."

"We'll look good together," The man said, earning a scowl from her, "But I wear a suit because I'm a part of the Mafia."

As soon as he finished saying that, Kyoko waved her goodbyes and ran off before she could protest against the idea of her being with the creepy man beside her. What the hell was this generation thinking? She and this man? It was like saying she was going to go out on a date with Kakashi-sensei, looks like a good idea but in reality it would be a horrible idea. Besides, she doesn't deal with civilian men especially after the war and where did she hear about the Mafia?

Maybe, she should ask Sasuke about it since he seemed to know more about these things then her.

"Mafia seduction," the man said, snapping her from her train of thought as Tsuna stepped out of his hiding spot.

"What does that mean?" Tsuna asked.

Naru rolled her eyes. "It didn't seem to work on me."

"You're still here aren't you?" the man pointed out, giving her a smirk. "And you aren't that irritated."

"Maybe it's because I'm concern for my student and not because of you," she retorted. "I'm worried about what's going to happen to Tsuna if he spends anymore time with you."

The man ignored her and stared at the young boy, who just gazed at the two of them in curiosity. "You've a crush on the girl don't you?"

And she would take that as her signal to leave.

When two males started to talk about their love life, Naru knew she needed to get out of here.
