Chapter 1: My Home Tutor, Reborn

Tsuna's POV

I never expected our lives to turn upside down when wemet a baby…A FREAKING BABY! Clad in black suit, underneath it was an orange shirt he also had a matching black fedora with an orange strip around it and a green chameleon with two really big eyes sticking (A/N: well like crawling or living) on it…and that baby was supposed to be my home tutor! Home tutor of what, anyway? Hmm…maybe being a MAFIA BOSS of a powerful family, which my sister suggested? Pssh…that's not going to happen and this so called mafia does not exist in this world.

Normal POV

Sawada Tsunayoshi, your typical teenage gi-ehem-boy…commonly known as Dame-Tsuna in his school for him being the moooost intelligent and mooost athletic student you'll ever find in Namimori School. He was sooo popular that whenever someone sees him they would greet him rather politely, 'Oy its Dame-Tsuna!' or be kind to him, 'Give me your lunch money Dame-Tsuna or die' and they would fight among themselves since they would want him in their team 'We don't want Dame-Tsuna in our team! We'll just probably lose!' Can't you just hear the sarcasm in my voice, ne? (A/N: I love you TSUNA! TT 3 TT)

Though he was an utter failure…FAILURE…he had some good points for being a DAME. For a dame he has a good heart. Never did he hold a grudge against those who called him a Dame. He was just toooo kind! But what Nana, his mother, love about him the most despite him having low grades (stab), apathetic thing for sports (stab stab) and no course in life (stab stab stab stab stab), he was a good big brother (no more stabs). A VERY loving big brother. (A/N: I think you know what happens to a character when you hurt/insult him/her with words that they do not like to tell them in their face…staabbb~)

Yes...Dame-Tsuna has a younger sibling…

At first nobody would not believe that Sawada Tsunayuki was Sawada Tsunayoshi's little sister. The little girl was a bit…well completely different compared to her brother. Yes she was a shy girl like her brother with averages scores, a thing for sports despite her clumsiness and she was quite known in her school, not because she has a dame brother but because she has this kind of charisma that makes almost everyone in her school bow down to her. But never did the two siblings think about that (their differences in school performance and other shits) as long as they loved each other.

Sweet isn't it?

It always made Nana squeal in delight whenever the two siblings were hugging each other or doing cute things that would make their mom gawk at their cuteness when they are together doing their 'adorable moments'. Her two kids were just soooo adorable especially her youngest since her youngest was a girl. Oh how she wished her husband was here to see her little girl grow into a fine young lady. Too bad he was in who knows where, digging whatever things with his mining tools. *cough*Italy*cough*cough*

Her Tsunayuki had a heart shape face with rosy lips; her hair was like her father's bleach blond hair that was spiky like her brother's (A/N: like Primo's! O/O) but her hair's length wasn't like her brother's obviously…her wavy hair stopped just below her shoulders, her eyes were as big as her brother's and mother's but her eyes were a bit smaller and like her father's eye color. (A/N: if you don't get it…just imagine a female Tsuna with blond hair like Primo but has long wavy hair…get it? Good.)

She'll be an eye candy…someday. Oh how her father would love to kill someone when someone gets TOOOOOO close with his daughter. His oh so adorable little princess.

Moving on…It was a sunny day and the little birds sang and the neighbor was peacef-

"HIIEEE!" our favorite brunette shouted as he got up from his bed and hastily wore his school uniform. Stepping out of his room, fully dressed, he got his other sock and tried to wear it while hopping towards their stairs with his bag on his shoulder but as we all know that him being a klutz, he fell down the stairs and landed on his face. Ouch I must say…

"O-onii-san! Are you alright?" Tsuna's younger sibling dashed towards him, making sure that he was perfectly fine. It did hurt but he never wanted his sister to know that he was in pain…especially his poor face. Poor (Dame) Tsuna. Slowly standing up, after putting his socks, he gave a reassuring smile to her as he told her "I-I'm fine Tsuki-chan" patting her head, tenderly. (A/N: TSUnayuKI)

Tsuna's sister puffed her cheeks childishly letting him know that he was ruining her hair that she combed so hard (A/N: with her Dying Will…lol). Tsuna just smiled sheepishly at her and with that, he was hugged by his sister lovingly; her head rubbing his tummy affectionately as he returned the hug with a smile, knowing that he was already forgiven. (A/N: Does anyone know how tall Fuuta is? Coz Tsunayuki and Fuuta have the same age)

"Ara…Tsu-kun and Tsu-chan are so adorable~!" their sisterly-brotherly moment was interrupted when they heard their loving mother's voice by the kitchen door. She was cupping her slightly pink tinted face like a school girl with the wiggling effect. (A/N: Some people call Tsunayuki different kinds of names. Like Tsuna he calls her Tsuki while their mom calls her Tsu-chan)

"Oh how I wish I bought a new memory card for our camera. The others were full already" She sighed, wishing that she took at least one shot…ONE SHOT…to capture that adorable moment that her two children shared. 'Oh well there are other adorable moments those two can make in the future!' Nana thought as she squealed unintentionally in front of her children making her look…uhh…you know what I mean.

"MOM~!" both her children yelled embarrassingly, their cheeks were painted in red. "You already have 7 or more albums of us having our 'adorable moments' since Tsuki was 3 years old!" Tsuna whined while his sister agreed with him, nodding vigorously but stopped; realizing something. 'When I was 3 years old?' she thought, not believing what her brother just said. 'That long?' again she could not believe it. "And it's still accumulating~!" their mother seemed proud about her, collecting pictures of the two of them. 'If mom keeps this up, I bet those pictures will be an autobiography by the time we're dead' Tsunayuki sighed inside her head.

See glance at the wall clock on top of the kitchen's doorway and sighed again. 'We're going to be late…' she thought and seconds passed till it hit her like a bullet that was aimed on her forehead. "HIEE! Tsuna-nii-san, we're going to be late!" she shriek making Tsuna look at the wall clock and did his famous 'HIEE' as he got his and Tsunayuki's belongings (with their bentos inside), pulling his sister towards the doorway to put on their shoes and make a dash towards their respective school.

"Bye Tsu-kun~! Tsu-chan~!" she waved from their main doorway as her children dashed towards their school, hoping that they wouldn't be late for school…or else…*insert tonfa here* (A/N: should Hibari have a younger brother to pair up with Tsunayuki or not?-_-)

Running as if they were in danger…well…let's just say Tsuna will be in danger when a certain someone bites him to death if he's late…they both made a sharp turn as they saw Tsuna's school coming to view they perk their heads up that they still have 10 minutes or so to spare so they wouldn't be late. "W-we're…huff…al-almost…huff…there" Tsuna huffed, happy that he wasn't going to be bitten to death by a well known prefect in Namimori.

Nearing Tsuna's school both siblings jogged and eventually walked since they didn't have to hurry anymore since they were practically safe from being tardy. "That…huff…was…tiring" Tsuna stopped in front of Namimori gate, both of his hands clutching his knees while getting his breathing back. "That…was nice" Tsunayuki said, tired from all the running. "It ain't fair. You have a thing for sports." Tsuna frowned as he finally got his breathing back to normal making Tsunayuki smile at him softly.

"Well…I'll see you later Nii-san" she said giving him a quick hug and started jogging to where her school was that was a couple of blocks away from her nii-san's school. "Bye Tsuki-chan" he waved and faced hel-…I mean school…yeah school…not hell…or anything.

So here he was, at the gate, now walking towards their school's entry, where their shoe lockers were. While removing his brown shoes to his school shoes, he overheard a bunch of girls that was whispering not so far from him.

"Hey isn't that Dame-Tsuna?" girl 1 asked among her friends. Though even it was a whisper Tsuna can still hear their voices.

"Yeah he is. What do you want from a no good guy anyway?" another girl answered

"Did you see that little girl with him awhile ago by the gates?" girl 1 asked again

"Oh! You mean that cute little girl~? She was sooo cute I wish she was my little sister" one of the girls squealed

"Yeah that cute girl, I sure pity her" She said, it seems like the girl was pouting

"Oh I get it, you pity her because that cute little girl's Dame-Tsuna's younger sibling" one of the girl's friend answered

"No way! I heard that she was well known in my younger brother's school, even thought she is quite timid. He even has a crush on her!" she said in a shock voice.

"I feel your pain…At first I didn't believe that she was Dame-Tsuna's sibling since they were different in everything. But when I saw them together they really look alike! But she's cuter and waaay better that her no good brother~" the girl replied making the group laugh as they continued with their mustering.

'Same old, same old' Tsuna thought passing the group of girls that was still talking about him and his sister as if he wasn't there. He knew that the both of them were different from each other but he would never hate his sister just because she was waaaay better than him. So what if they different whenever if comes to school performances? It doesn't change his love for his sister anyway. (A/N: awwww :3)

Right after school, Tsuna got his things and made a dash towards his sister's school to pick her up. 'Good thing I wasn't assigned for clean up duty today' he sighed with relief as he got closer to his sister school, Namimori Elementary. 'And no one forced me to do it…again'

He soon found his sister waiting by their school's gate, patiently, slightly swaying her body back and forth while quitely humming a random tune as she waited for him to come and pick her up. She suddenly stopped when she found Tsuna nearing her school's gate. She smiled and jogged towards him but since they were siblings…she tripped.

Tsuna slightly panicked and went to her quickly. "Are you alright?" he asked her while his sister picked herself up while scratching the back of her head with a sheepish smile. She was like and looked like Tsuna whenever she did that. "Ehehe…I guess it runs in the family. Tripping and all" Tsuna laughed with her, happy that his sister wasn't hurt and that she made a funny comment about their clumsiness.

Soon they were able to go home…with a few trip over here and over there of course.

NEXT DAY

Today Tsuna was sleeping comfortably on his bed, mumbling the name 'Kyoko-chan' with a goofy smile on his sleeping face. "Ahehehe…" he laughed in his dream not knowing that Nana was calling him for breakfast already.

With a sigh from downstairs, Nana went upstairs to wake up her son so that he won't be late. She barged in without knocking since she knew that her son wouldn't answer it. 'Playing video games again' Nana sighed once more, looking at her son's tidy room. She picked up one of his dirty clothes and walked towards the sleeping teen that was on his bed, mumbling something that she could not decipher whatever her son was saying.

"Tsu-kun, wake up or you're going to be late for school" she said, shaking Tsuna's shoulders gently which only resulted her son to swat her hand away gently, turning to the other side of the bed and doze off once more. "Sigh…" she then found a crumbled paper by his desk and curiously opened the poor paper that had red markings on it. "Tsunayoshi" she used Tsuna's complete name. "Who got an 8 on their Math quiz? Hmm?" she asked which made her son immediately wake up and snatched the paper away from her hands. "MOM!" he whined, hiding the paper behind him. He was embarrassed that his mom found his (failed) Math quiz…again.

DOWNSTAIRS

Tsunayuki sighed as she heard her mom lecture her big brother to take things seriously and blah blah blah…she couldn't hear quite well since she was too engross with her Mom's yummy breakfast and that she was in the first floor. "It's good isn't it?" she asked the stranger in front of her. "Of course" the stranger drank his espresso while she continued to eat her breakfast, not caring if the stranger was eyeing her intently.

"HIEE!" she heard her brother scream and a lot of loud sounds that were like 'thuds' and 'oofs' as if someone fell down the stairs. Well someone did as she saw her brother's upper body on the floor while his other half still on the stairs. "O-onii-san!" she got up from her chair and went where her brother was but stopped when a small black blur ran passed her to where her brother was.

"Itai, itai, itai" Tsuna mumbled, rubbing his poor nose to ease the pain as he saw a baby when he opened his eyes

"Ciaossu" the baby said

"Ara? Is the home tutor there already?" Nana's voice was heard from upstairs as she went downstairs to see her new son's home tutor that would teach him free as long as he was to live in their house and give him free food to eat. A great deal, right?

"Home tutor? Mom I told you I don't need one!" Tsuna yelled, still rubbing his red nose.

"Tsuna-nii-san, are you alright?" Tsunayuki emerged from the kitchen. Her face was filled with worry. She knew that this is a daily routine in their household but she can't help but be worried when her brother hurts himself. "Ah…" Tsuna said with a smile which made Tsunayuki sigh in relief.

"Are you ignoring me Dame-Tsuna?" the baby asked, kicking Tsuna on the head as he back flipped to where he awhile ago.

"Hey that hurt! Who are you and what are you doing here anyway?" Tsuna yelled in frustration since he was kicked by a baby, the kick added more pain to what he just receive awhile ago when he fell down the stairs and that baby called him Dame-Tsuna. He never knew that even a baby knew his accursed name.

"My name is Reborn and I'm going to be your home tutor from now on" the baby pulled his fedora hat down with a smirked which made the Sawada sibling cringed in fear.

Tsunayuki's POV

I never knew that meeting someone would turn our lives upside down…by a baby named Reborn.
