Hi guys, it's another crack fic. No, this was not planned. This was born from a joke where someone on tumblr asked why no one would write Secondo reborn as Tsuna. The joke went "Well that's boring, why don't we write about Vongola Quarto instead?" After going through an evolution of memes, it has finally gained a life of its own. Welcome to the fanfic where Vongola Quarto is reborn as Tsuna. With great thanks to exocara, Wryvel, athanatosora, kilewolf, maneater and Enitsirhc Bob and everyone who supported this idea! This chapter is merely introductory and features little to no crack besides cute Tsuna fluff. Please enjoy.

The Five Star Chef Decimo Chapter 1: Five Years Old Again

It was finally the end of his life. He should be fortunate that he was able to have a peaceful death. The man panted heavily, surrounded by many people. Some were family members, the rest were men in black suits. He grimaced, being reminded of his life. He clenched his blanket tightly, reliving his life once more. He had always wanted to be a chef, but there was no one to be the Boss once his brother died.

"Quarto." The man in a white cloak greeted.

"Carlo. Please." The bedridden man insisted, and coughed.

"Uncle Carlo, is there anything else we can do for you?" He asked in a concerned tone.

"Please. Give me some pasta." Carlo pleaded.

Without delay, they hurriedly brought the plate of pasta to him. He gave a look of disapproval before digging in.

"Merda, none of you can even cook it right." He spat, leaving it uneaten.

"I apologise." The man with the white cloak bowed and the maids took the plate away.

"Michele, just do what you want with the Famigila." Carlo said, coughing.

"Understood." He then sat down. "Uncle, is there anything else?"

"Not really. If there was one thing I regret… it was not being able to become a chef." The world faded to black, ending his short life.

Opening his eyes again, Carlo found himself no longer the Italian man he used to be. He found small chubby hands in front of him, and he flexed it. They felt so soft, with no scars or creases. Smooth skin. He got up and stared at the room he had. Painted in light green, there were toys scattered all over the floor. Posters of robots were plastered across the wall, with a action figure on the study table. He walked over and played with it, smiling. Though his adult self wouldn't even give it the light of day, his inner child was overjoyed at being able to play with toys again. He walked out of the room, feeling the hard wooden floor beneath his feet. He paused at the door to read what was on it. It read… 'Tsu...na'. Somehow, he managed to read it automatically.

The boy then headed to the toilet. At the sink was a small orange toothbrush and a bigger pink one. Placing a stool near the sink, he stepped on it and noticed his features. Chestnut brown eyes and a big brown mass of hair occupied most of his head. He blinked in surprise as he felt his soft, fluffy hair. His face was smaller, and his eyes were wider. He put on his biggest pout but failed to make himself more intimidating, rather more cuter. Shaking his head, Tsuna began to take the toothbrush and brush his teeth. He noticed the toothpaste were in pictorial characters he could barely recognise.

He looked around the house. It seemed very small compared to the mansions or regular houses he had seen at home. The wallpaper and tatami mats seemed so… foreign to him. The language he had seen definitely did not match the languages he knew in his past life. Down the stairs, his body instinctively knew where to go. A kind brown haired woman greeted when he entered the kitchen. The smell of the omelette rice wafted through the air, making him drool. She held the frying pan with one hand, and chopsticks in the other.

"Ah, you're up very early, Tsu-kun." The woman said, and he smiled. "Breakfast is going to be ready soon. Mama will get this done quickly!" He nodded.

Tsuna watched his mother lift the frying pan up. Then, she tilted the pan downwards, with the rice at the edge of it. Her chopsticks moved to pick up the thin yellow omelette on both sides and flipped it towards the rice. It covered the rice, and she repeated it until the omelette wrapped the rice completely. Overturning the pan, it landed nicely on the plate. She then grabbed a paper towel and pressed on the sides, forming its shape nicely. The paper towel drained the oil away. Grabbing a bottle of ketchup, she poured the sauce in a zigzag manner. The finished dish made its way to the table. He stared at the dish curiously. A lump of yellow on the plate.

"Today, I made omurice!" She said cheerfully.

"Itadakimasu!" He dug in, wolfing it down.

'This is so good!' He smiled, the aromatic mix of freshly cooked rice and spice filling his nose as he took a bite.

His name is Sawada Tsunayoshi and he is an ordinary Japanese five year old boy who lives with his mother, Sawada Nana. They live in a two-storey house, and could pass for a middle-class family. His father was barely ever home, and since he had no memory of him he didn't bother. This life seemed ten times better than his past life. A loving mother, and a peaceful time. He stared in awe at the television, displaying colourful images that could not fit in the box itself. He walked towards it and stared at the bright screen hurting his eyes. He looked behind the television but only found cables and wires He reached out to knock on the screen, only to be greeted with hard glass. He pressed his face against it, and heard buzzing sounds.

"Tsu-kun, don't stand so near to the screen! You will hurt your eyes." Nana warned from the kitchen.

"Okay." He ran off.

There were things that kept things cold. He headed to the kitchen and stood in front of the refrigerator. Tsuna stared at the thing that towered over him and opened it, putting his hand inside. Cold air overwhelmed him and he open his arms wide, taking in the cold. Then, the refrigerator screamed, causing him to jump and close the door. He stared at it for a while. Then he opened the door again and continued to do so.

"Tsu-kun, what are you doing? Is it very hot? You know we can turn on the air conditioner you know! Don't waste electricity!" Nana finally picked him up and carried him away.

She went to his room and placed him on the bed. She grabbed a remote control and switched the air conditioner on. Tsuna stared at it, trying to feel the cold air.

The phone rang, and he removed it from its position. He couldn't hear anything, so he placed it back. Then it rang again. He picked it up, this time able to hear something.

"H-H-Hello." He said nervously. "May I ask who is this?"

"Is that my cute tunafish!?" A gruff voice greeted, giving the boy a sense of familiarity.

"Who are you?" Tsuna said, looking around.

He walked out to the front door and saw no one there. He then tried to look behind the phone. No one was behind the phone. He then pressed the receiver onto his ear.

"I'm your papa! Do you remember me?!" The voice insisted.

The boy attempted to remember the person who went by that name and connecting the voice to it. He could only imagine a shadow. He pondered hard, but failed in vain.

"Tsu-kun, who's on the phone?" Nana called out before he could answer.

"Mama, there's this weird person on the phone who's calling him Tsuna's papa." Tsuna said, and could hear the other person choking on his saliva. "He's calling me tuna for some reason. Mama, am I going to turn into a fish? Is he going to come and take me to become sushi?" He asked, tears about to leak from his eyes.

His mother laughed, and he became confused.

"It's okay, Tsu-kun! Don't worry, he won't catch you. Give me the phone." The boy handed it over and she held to to her ear. "Dear, it's so rare of you to call! Don't worry, Tsu-kun is fine. He thought you were going to kidnap him! You should really come back soon before he forgets what you look like!" Seeing his mother very calm, the boy relaxed.

Still, he wondered why the voice didn't say anything the first time.

"Tsu-kun! Wake up! It's time to get ready for school!" The boy moaned, waking up at an ungodly hour.

Half and hour later and with a bright yellow cap covered his fluffy hair, Tsuna yawned, wearing the uniform and carrying his bag. He turned around to see his mother staring at the photo who she claimed was his father. The photo frame sat on the table, depicting a smiling idiot with a pickaxe. She gave a somewhat sad glance, but it disappeared into a smile.

"Mama, let's go." He said, snapping her out of her reverie and she grasped his hand.

They walked all the way to school.

"Mama, when is papa visiting?" He could see some hesitance behind her calm face.

"He will be visiting soon." She answered confidently. "If Tsu-kun will be a good boy at school, then he will come home faster." Nana proclaimed.

"Really? Then I'll do my best!" He cheered.

"Be a good boy, okay?" She said, and gave him a kiss on the forehead.

Tsuna watched his mother leave and disappear into the distance. Then he turned around and entered the school. Everyone placed their bags in the shelves and sat in the classroom. Their teacher came in and then started their activities. They changed into their sports attire and began exercising together. The boy found himself in one corner with no one to group with. A part of him said that because he was no good at everything, no one wanted to be with him. No matter, he didn't mind being alone. The whole class stood in a circle and followed their teacher's movements. Lean to the left, right and swinging their arms. Then they began to move around. The black haired boy in front of him blocked Tsuna's way. The brown haired boy tried to get around him, but failed.

He then moved in front to get a glimpse of the boy. His mind told him that this person was Ishikawa. Ishikawa proceeded to shoved him aside and he staggered a bit. Tsuna then slammed back against him with all his might, sending his target onto the floor. A sharp whistle blew, stopping the exercise and everyone gathered around them. Ishikawa began crying, hugging his scraped knee.

"What happened?" The teacher walked over.

"He pushed me!" The black haired boy cried and pointed at Tsuna.

The teacher looked over at him with disapproval, folding her arms.

"Sawada-kun, did you do this?" He nodded sheepishly. "Don't push the other kids, Sawada-kun. People will get hurt if you push or shove them. Understand? Now apologise and go stand in the corner." She ordered.

He walked up to Ishikawa.

"I'm sorry." Tsuna then went to stand in the corner and pouted.

If there was one thing that probably annoyed him, it was probably having to live like a child again and learning how to act like one. He felt like a fish out of water. 'Maybe I'll be lonely in this life too.' He thought.

"What's wrong?" A voice spoke, and he looked up. "Why are you standing here all by yourself?" A orange haired girl asked.

"I got punished." He answered, and shifted his feet. "For pushing someone."

"Why did you push him?" The black haired girl beside her asked.

"He pushed me first." The boy defended himself.

"You shouldn't have pushed him back. You'd end up in the wrong too." She pointed out.

"It's not fair that he gets away with it." He muttered.

"You just have to tell the teacher. That's what my mother told me to do. Then I won't get into trouble that way. Good kids don't do bad things that worry their mothers." She chastised him.

'Be a good boy, okay?' His mother's voice rung in his head, and he looked up at them.

"Do you have any friends?" Tsuna shook his head and then looked down.

A memory of his past life haunted him.

"Woah, you're from Vongola Famiglia right? Let's be friends." The person put their arm around him. "No harm in being friends with me, right?"

"Go away." Carlo shoved the person arm's off him and walked away.

"Hmph, you think you're so special, big shot?" He clenched his fists tightly.

'They'll probably leave me anyway. People only want to be with the popular ones.' He thought. The orange haired girl looked at her friend, who only shrugged.

"Then do you want to be friends?" He looked up, surprised. "My name is Sasagawa Kyoko. Nice to meet you." The orange haired girl introduced herself.

"Kurokawa. Kurokawa Hana . I'm just tagging along because I think Ishikawa's rude and deserved that fall anyway. What's yours?" A smile crept up his face.

"Sawada Tsunayoshi. Thanks for being my friend!" He jumped up.

As long as he could have friends, he didn't mind.

"How was school today, Tsu-kun?" Nana asked, holding his hand.

"It was fun! I made two new friends today!" The boy chirped excitedly.

"That's great to hear!" She said with a smile.

"Where are we going?" He asked, noticing that they weren't on the way home.

"We're going to buy groceries before going home." She said. "Since you're such a good kid, I'll buy more snacks for you!"

"Yay!" He jumped in joy.

The sun began to set, giving the sky an orange hue. Namimori's shopping district came into view. Tsuna stared in awe. Many people were walking around to their destinations, carrying shopping bags. Teenagers in uniforms hung out at the arcades and cafes or fast food establishments. Mothers were accompanying their children, shopping for clothes or groceries. The two of them headed towards the supermarket. Cold air embraced them, relieving them from the scorching heat outside. A soothing music played and a wide variety of colours greeted them. He stared at the variety of options they had. So many to choose from! The supermarket was not very crowded. Shoppers were pushing baskets or carrying them. He held tightly to his backpack, and watched his mother take the basket with the trolley. The basket sat nicely in the trolley, and he helped pushed the trolley along.

"What do you think we should eat this week?" Nana asked her son.

"Pasta!" He answered cheerfully.

"Ahaha, you really like pasta a lot, don't you? Hmm, what about some hamburgers?" He beamed at the sound of that.

They headed to the grains section to get bread and pasta. They also got milk, eggs and fish. All their groceries stacked up nicely in the basket.

"I guess I should buy this too." Nana grabbed a curry roux from the shelf. "We'll be having curry soon, Tsu-kun!" She placed it in the basket, and he took it to see for himself.

Tsuna curiously looked at the packaging. He read the contents and noticed there was always a table printed on most of them. He made note to go study them when they got back home. At the poultry section, she bought pork, chicken and sausages. They were placed in the basket. Whenever they arrived at the section, Nana would get her son to read them out and pat him on the head for getting it right. Afterwards, they checked out and were on their way home. When he thought about it, life was actually not bad.

He might get used to this.

Things will progress chronologically. This fic is based on the headcanon that Vongola Quarto had always wanted to be a chef but ended up being boss. AKA, he's the first Tsuna who got screwed over by the Vongola Family. The really funny parts come alter, but I had to write the childhood arc to show how Quarto is different, yet similar to Tsuna in some ways. I hope you enjoyed the cute Tsuna fluff that unintentionally got written in this chapter.
