Background of Eight Grade Syndrome: it was a mental state occured in Japan. Psychologist stated it was the cause of puberty. Eight grade syndrome can leads someone who thinks that they are different from the others- which results them acting as if they are an anime/manga characters and set up their own social barrier towards society.

Eight year syndrome is real in Japan guys, I'm not making shit up. For your information, this was inspired from Chuunibyou anime. No hates..

According to the universal survey, parents from all over the world agreed by this statement:

'One of the hardest things of being a parent is seeing their children grow up.'

Everyone couldn't have agreed more, for it was undoubtedly true.

As children's age matured from year to year, their personality changed too—they lied, stopped listening, and being seen with their parents on public brought a flush to their cheeks. Sometimes, parents can't even tell if they were their children anymore—for their sons or daughters have turned into something different, as if they were a brand new person.

But of course, parents couldn't do anything about it. It was inevitable. Everyone had gone through that stage in his or her lives –the stage of adolescence, so it was no surprise. The cycle passed on that it became a tradition….

But the parents of Sawada Tsunayoshi seemed to have the hardest time.

Tsuna was supposed to be doing his homework—his English book laid across his study desk, waiting to be touched. Instead, the brunette was hanging on his drawers, scooping up random items—an old sprinkler, can opener, and a bunch of enigmatic antique displays; he scattered them across the room.

"Tsu-kun!" his mother's voice echoed at the distance. "Are you done with your homework?"

Tsuna swept his gaze to the door in an alarming manner. The brunette got to his knees, tossed the English book to his bag and laid himself in the middle of the mess on the floor.

Nana Sawada walked in, sighed inwardly, hands on her hips. "Tsu-kun, have you done your homework? What are you doing on the floor?"

"Mom!" Tsuna jerked to his sitting position and pointed towards the window. "They had come!"

"They?" Nana's eyes rolled slightly, looked unimpressed.

"The organization that tried to steal the fire codex!" Tsuna said. "Get out mom! Or else you will be caught up in the mess!"

"Oh, I appreciate the concern." Nana chuckled mildly. "So, is this organization is your excuse to not do your homework?"

"Screw the homework mom! If they come and attack, everything will be blown into pieces!"

Tsuna strolled to his drawers and took more of his peculiar possessions out— a magical crystal ball; he called it, which was just a plastic, transparent ball Tsuna had purchased on the toys store on Christmas' sale.

"I find it! The codex is inside!" Tsuna sighed in relief, particularly talking to no one. "Now I need to make this thing disappear from the enemy's radar…."

Nana was about to talk her sense to her son until the doorbell buzzed. She clicked her tongues in irritation and slammed the door shut behind her. It was unusual to see Nana Sawada upset –she was a kind, cheerful and outgoing mother for her age, but she was at her limit –especially when her son went on about his eight grade syndrome delusions.

While the elder woman was greeting her husband, Tsuna was pouring the water from his sprinkler to the crystal ball, and he shouted victoriously.

"Yes! At this rate the organization will not be able to find the codex! I have saved the Sawada Household once again!"

Nana held the urge to cry. She turned to her husband, anxiety was written all over her face. "Dear, what should we do? We have called him the fifth psychologist the other day and it doesn't work on him!"

To her surprise, Iemitsu stroke Nana's hair confidently and grinned cheekily.

"Don't worry, I have found someone who can help our son! He was recommended by my boss."

The day after:

"Tsuna…" Iemitsu called his son, head tilted to the stairs. "Come down son, we need to talk."

Tsuna obeyed. The brunette descended, and grinned when his eyes fell to his father. Iemitsu didn't stayed at home often, and Tsuna had come to miss his presence.

"Welcome home, dad!" Tsuna greeted him. "So you are back after challenging the final boss on the last dungeon!"

Iemitsu smiled awkwardly. Tsuna must've meant that he was back for work, whatever; Iemitsu was better at tolerating Tsuna's random bickering than his wife does –he found it amusing, sometimes.

"Tsuna, from today, a new home tutor will be attending you."

"Eh? You mean another one of those espers who were able to influence one being to another being's realm by listening from both sides?"

In Tsuna's language—the psychologist.

"No a home tutor…not another psychologist expert." Iemitsu scratched his head, sighing. "Fine I will speak in your terms –a skilled expert, your master, is going to train you to become the fire warrior."

"You mean my shufu?"

"Yes, your shufu." Iemitsu groaned inwardly.

"But I don't need a shufu!" Tsuna protested. "I am already strong myself! I have been fighting overseers from the organization for fourteen years—"

"But you see…" Iemitsu looked deeply into his son's eyes. "The organization is going to get stronger. They will be back with more followers on their side. They will not sit still for fourteen years of loss, Tsuna…"

Hearing his father, Tsuna contemplated on his father's words. Good, he fell for it.

"Then, I will wait for his arrival." Tsuna said it formally, and he bowed before he departs. "Thank you for the vital information, father."

With that, Tsuna bolted to his room.

As Tsuna was out of sight, Iemitsu sank to his knees in relief. "Damn it…talking like that was so tiring…"

"That's my husband!" Nana teased him. "You're so good at it that I got creeped out for a second…"

Iemitsu sweat dropped. His eight-grade syndrome act was really perfect that even his wife got creeped out. But, he credited himself for being able to pull that off. "I see…."

That afternoon, a light knock intruded the Sawada household. Nana immediately attended the guest and saw a little baby—huge eyes, with a tuxedo and a green chameleon hanging on its huge hat.

"You must be Reborn-san!" Nana sunk to her knees in order to face-to-face with the baby.

"My name is, Home Tutor Hitman Reborn!" the baby spoke formally to Nana's surprise. "I was assigned here by the ninth to make your son as the next boss of the Vongol—"

"Ah! Hello Reborn! Nice to meet you!" Iemitsu cuts it before Reborn could go further to confuse his bewildered wife.

"Iemitsu! Then ma'am, can I talk with your husband in private for a minute? This is important."

Surprised how a little baby could be so smooth with words, Nana nodded and left the boys on their own. "Then I will be making the tea."

As the woman left, Iemitsu told Reborn about Tsuna's condition—who was currently unable to take the heir as the tenth boss of Vongola—one of the strongest mafia organization in Sicily; Reborn came here to deliver that fact.

"Well leave it to me!" Reborn said confidently. "I have trained someone similar like your son in the Cavallone family, so I am already used dealing with eight-year syndromes."

"Tsu-kun!" Tsuna heard the familiar knock on the door. "Your tutor has come."

Tsuna's gaze turned to the door, his drawer, the toys on the floor and the door again. He scooped up the messy items and threw them all inside his drawer. Seemed like he's cleaning up, but actually Tsuna was taking a new set of toys and scatter them on the floor again—old white gloves, a torchlight and a set of marbles.

"My shufu has come…" Tsuna whispered huskily to himself. "I will get stronger…and I will be able to fight the organization!"

Tsuna smoothed the gloves to his arms, put the marbles in his pocket and held the torchlight between his fingers. He opened the door, and expected an old, beardy man with sharp-asian eyes to be his new 'tutor' as what the commoners called it –like the one in Kung Fu Panda.

But there was nobody to be found.

"Shufu!" he yelled. "Where are you?"

. . . . .

"I am here, dame-Tsuna." A voice from below was found.

"Hieee!" Tsuna jerked and saw a little baby in tuxedo was looking deeply at him. His eyes were pure black, as if it was looking into the blackness, and it reminded Tsuna of the alien race in one of his video games.

"Oh my god! Dad was right! The organization was sending an alien from the outer realm and disguise as my shufu!"

"Shut up dame-Tsuna." Reborn kicked Tsuna's leg, and left the brunette cried in irritation. Despite his small feet, it has the power of five horses. "I am your shufu."

"You're lying…" Tsuna winced. "You're just another one of those disguisers in the organization! I wouldn't fall for your trick!"

Tsuna sidestepped and do a certain pose –when superheroes were about to unleash a particular move. He smoothed his fingers, switched the torch light on and placed the marble in front of his right eye. He chanted.

"I am the Bearer of the Flames. In the name of the sky, I banish you out of this world and send you to hell. May the god of the flames gave you mercy for your treacherous act—"

"That's enough, dame Tsuna." Reborn slapped Tsuna's cheeks and send the boy flying and crashed against the wall. Tsuna winced; it was twice painful than being slapped by her mother or hit by a baseball bat combined. Who the hell is this baby? Why does he have strength of a professional hitman?

Hitman…..?

"You sure have good imaginations for an eight grade syndrome." Reborn smirked, amused. "And I have good news for someone like you. That bullshit imagination of yours will be a huge help for the mafia."

"Ma…fi..a…" Tsuna tried to sit on the spot, yet he winced halfway. "What are you trying to comply, warrior from the overseers?"

"I don't belong in the overseers." Reborn played along, yet his voice was filled with interest and mild amusement, as if he enjoyed it. "I am a hitman from the Vongola Family."

Tsuna squinted curiously, shook his head. "Vongola family? From what part of the continent this organization comes from?"

"Italy, an existing country." Reborn said. "Not in Twinleaf Town or the Fairy Alley in your non-existent world."

Tsuna ignored him. "What are your motives for approaching the bearer of the flames, whom the god of the sky had summoned?"

Reborn smirked. He found Tsuna's weak point.

"The Vongola had recognized your power, Bearer of the Flames. The Vongola's enemy is the organization you've been blabbering about. Because of your recognition, the ninth Vongola boss wants you to take his place as the tenth Vongola boss. They entrust you to take out the organizati—"

"Wait wait wait!" Tsuna interrupted, to his surprise and Reborn, he sounded sober. "Are you trying to tell me the organization is real?"

"It does." Reborn said in a straight face. "Did you doubt it? I thought you've been fighting with the organization for fourteen years."

"No no, listen to me..." Tsuna said. "I have been having these eight-year delusions…and I view the world differently than anybody else. The things I do are infected by my mental state and sometimes for fun….but I never thought it actually exist!"

"It does." Reborn replied. "The Vongola have been fighting it for centuries. Unlike you, who took various toys and talk to the window as if it was coming."

"I thought it's just a mild prank…" Tsuna mumbled to himself.

"What is it? Where did your eight year delusions go? We need that imagination in the Vongola family."

"I don't really know this Vongola thing you're talking about." Tsuna rushed, words jumbled. "But let me tell you that all I've been doing in my life was just a harmless prank I done to myself. I don't mean to fight any organization or something like that…"

"Oh….you're scared now?"

Tsuna's stomach sank. In his entire life, he had been the Bearer of the Flames, the man who will face the overseers from the organization and protect the world with his hands. He was known as the highest rank out of all bearers, and has many friends on his side. He had risked his life, family, money to build the ultimate weapon to fight the organization and swore to defeat it at all cost….

But that's all just his fantasy! His eight year syndrome delusions—purely sub conscious!

The organization isn't real, bearers of the flames existed in myths, he didn't risk anything but wasting his money on enigmatic junk, and he failed all his tests at school and has no friends.

And here a baby from the unknown who was supposed to be his shufu to train the organization, no—a home tutor, a hitman, who will train the useless, eight year syndrome victim Tsuna, to be the tenth boss of the Vongola family to fight the organization. At first he thought Vongola was the name of pasta—a snack that will boost his energy by half during the battle with the organization in the evening, but now it was different.

Vongola was real. The real deal.

That means Tsuna has to fight, shed blood, and go against the overseers, no—people in the organization and fight them alongside Vongola. Not to mention, Tsuna, was the boss, the leader of the Vongola—who will coordinate the squad and commerce them into operation plans…

Tsuna cried.

It was impossible!

"That's it…" Tsuna muttered. "I will try to counter my eight grade syndrome. Reborn, now I am not someone with high fantasies…so leave me be…"

Reborn smirked and strolled out of the room. "We'll see."

And he left, while Tsuna could only think how cowardly he was.

Since when being an eight grade syndrome victim was dangerous? The question is, if kids who dream of fighting a certain group with magical powers, will they accept it in reality? It seemed cool with all the magic powers, costumes and fighting and all…

But it was a horrible fate. You fight, got hurt, meet friends, betrayed, fight more, has a high risk to die….

"No..no…it's scary…" Tsuna sobbed to himself.

As Tsuna ponder about his mental state, Reborn peered behind the door and smirked to himself.

"I can't believe I heal his eight year syndrome in a few sentence." Reborn thought. "But I won't have it healed…just yet."
