Vongola's Grandson

Inspired by Nurarihyonn no Mago. Sawada Tsunayoshi was deprived of his parents in an assassination which he narrowly escaped at the age of five. Timoteo,the ninth boss of Vongola, the most feared and powerful mafia in Italy in its decline, decided to adopt him as his grandson and successor. However, it seems that Tsunayoshi always denied his role as he cannot accept the evil and underground activities of the mafia. What is Vongola's future going to be? No pairings. Less-no-good-in-his-youth and slightly spoiled Tsuna! Warning : AU and OCC-ness.

Chapter 1

Becoming the master of all mafia

It was a beautiful day. Like many newly-wed families, the Sawada spent their time outdoors. The hyperactive Mr Sawada chose to hike although his son was barely five years old.
"Right! Only ten miles left to the peak!" Sawada Iemitsu, the father, said cheerily.
"Wait for us, darling!." Nana begged, not being used to strenuous exercise.
"Boo! Darling, hasten your step! Even Tsuna is faster than you!" The five-year-old Sawada Tsunayoshi, healthy and energetic, quickly caught up with his father.

But suddenly it rained cats and dogs.

"Oh no! In this kind of weather, we can't do the climbing," said Nana.
"Oh, yeah, have to take a ride home, then," suggested Iemitsu.
"But, dear, there is no bus left by this time around this isolated area!"
"Take a cab, then."

Hence, the Sawada took a cab back to their home town, Namimori. On the way back, the parents struck up a conversation with the cab driver in a friendly manner.

Yet, they noticed something was off. The driver was strangely gloomy and mysterious.

Nevertheless, nothing happened... at least until Mr Sawada said dreamily :

"It is the sky that envelops everything in harmony."

Before Iemitsu could react, a couple of bullets rang.

Bang! Bang!

Mrs Sawada screamed like mad at her husband's lifeless body falling on to her lap.
The driver turned to look at the boy and the woman. His face was full of scars and cruel expressions.

"Let's finish the boy first, shall we?"
"Stop!," Nana screamed at the top of her voice.

And with her hiking tools, she broke the glass.
"Tsuna ran for your life! Through the broken window!"
Tsuna was submissively climbing out while the driver was clearly pissed by having one target lost from his grasp.

"You woman! Die!"

Bang!

Only silence is what follows.
As the driver looked up, Sawada Tsunayoshi seems to have successfully escaped.
"Wait there, brat!"

Sawada Tsunayoshi was scampering for his life along the highway road with injured and torn legs from the broken glasses.

He panted. Tears trickled down his face. It was a struggle for survival.

Then he heard an adult's footsteps...

A harsh, coarse shout follows : "Die! You damn brat!"

Tsuna shut his eyes and heard two rings of bullet.

Bang! Bang!

He was hoping to open his eye to be welcomed by his parents to heaven.

But when he did so, he found himself still on that road. Why?

"Pwww... Young master is safe," said a voice.
"Report the headquarter! Master Tsunayoshi is safe and sound!" said another.

Then Tsuna felt a hand raising him up. He looked at his rescuers and noticed that they were all in black suits.

He was then taken to a black sleek expensive car.

"Who are you?" Tsuna asked.

"We are your subordinates, Master Tsunayoshi"
"Subordinate? And where are my parents? Are they alright like me?" Tsuna fired more questions.
The men started to wear grim expression on their face and said,

" I'm sorry, but your parents passed away in the incident."

Tsuna sobbed again, more heavily and was embraced by the man on his right.

"It's alright, master, now that you are safe."

"So, where are we going?" asked Tsuna while sobbing.
"Italy, your grandfather's house"

++++++++++++++++++++++++++++++++++++++++++++++++++ Vongola's Grandson +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Two days later, Tsuna was in Italy and met a kind old man who he was told was his grand father although the man was actually a distant relative and his father's boss, Timoteo, the Ninth boss of Vongola, the most powerful mafia in Italy located in the just adopted Tsuna to be his successor.

His father had actually worked as the head of CEDEF, or external advisor of Vongola.

But his great-great grand father was the founder of Vongola, so he had the blood of Vongola.
At their first meeting, Timoteo hugged Tsuna and said

"you are the only hope I have left. You don't need to know everything. I can't risk to lose you as well."

That is possibly because the other two candidates for Vongola Decimo and Iemitsu were ruthlessly assassinated as well.

From that day on, Tsuna was protectively brought up as the next Vongola boss.

He was originally fascinated by the mafiaso around him and saw them as hero until he was eight years old, when he started to realise Mafia was usually feared rather then respected.

For his safety, his relation and position as the next Vongola were kept confidential. He was only known as a normal adopted Japanese from an Italian family.

At school, he made his best friend, Kyoko, a girl from a Japanese expatriate family.

One day, the class president, Moshida,a boy from another Japanese expat. family, presented his research on Mafia family in Italy.

"Mafia is the most vicious underground organisation. We need to rid it of our society. The end!"

The presentation was received by loud clapping and eager praises.

Then Tsuna abruptly raised his hand and interrupted.

"That's not true! Mafia is the good guy!"

Sound of doubt arouse among the students.

"My family is a mafia, and every one there is nice! Gokudera-kun may always be at loggerheads with Yamamoto, but he is very smart!"

Whispers grew more louder while Moshida and the teachers were scandalised.

"Really? If that is true, what's your family's name, then?," asked Moshida sarcastically.
"Vongola!"
"Vongola, huh? The most powerful mafia in Italy."
"Yes! Yes! You sure know your stuff!"

Moshida smirked, "Yes, certainly. It's the family behind all the assassination, holocaust and drug dealings in this other words, the most sinful family in this country!"

"Wh...What?" said Tsuna in disbelief.

"It's alright, everyone. Anyway, such a powerful family is in a legend. It couldn't exist up to this age," Moshida continued with his display of analytical ability.

Everyone nodded in agreement, and Tsuna was turned into a liar.

Afterwards, Tsuna was subdued and disillusioned. He was also taunted by his friends for two following weeks.

"Hey, Vongola, can I have a lift? Well, just joking, ha ha," Moshida teased.

Tsuna only sighed in response.

"Hey, Tsuna-kun! Don't be dejected by such petty teasing!" Sasagawa Kyoko called at him.

"... I'm such a pathetic shame,"'replied Tsuna regretfully.

" It's alright. After all, we all have wild imaginations sometimes"

"Does that mean that you don't believe me!?"

"No, a kind-hearted boy like you couldn't possibly be that heartless, bloodthirsty Vongola!"

"Huh? Even you?"

However, before Kyoko could answer, Tsuna ran away.

"Hey, aren't you going to take train home as usual?" asked Kyoko.

"No, I'm too pitiful to face anyone now. I decided to walk home"

As a result, they parted way. But three minutes later, Tsuna found himself lost and eventually picked up by one of his bodyguard.

He got a ride home on a flashy sport car today.

"Young master, you should have taken the train home! You couldn't walk back to mansion. It's 20 miles away!" the bodyguard complained

"I know... I know..."

"What if an enemy found out your identity? Remember, you are the last heir of Vongola left!"

"Hey, Christopher, I am not directly related to the ninth by blood, am I?" Tsuna shot a question out of blue.

"Erm... Yes, since he adopted you, I suppose..."

"Is it!?"

"Still, you directly descended from Vongola Primo, so you are perfectly eligible to be our boss thanks to your blood of Vongola."

"S-So?," uttered Tsuna disappointedly.

+++++++++++++++++++++++++++++++++++++++ Vongola's Grandson ++++++++++++++++++++++++++++++++++++++++++++

Back at home, everyone was in a great hysteria and seemed surprised at the sight of their young master coming home safe and sound.

The ninth shouldered through the crowd of bodyguards and hugged Tsunayoshi.

"Oh, Tsunayoshi-kun. Where have you been? I'm so glad that you are safe!"

"W-What happened?," asked Tsuna.

Another man there explain," there has been an explosion on a train you are supposed to ride home!"

"It is alright now that you are safe!," said the ninth.

But before he could pat the brunet's hair, the boy ran to get his coat from his bodyguard's hand.

"Grandson, where are you going," asked Timoteo.

"To save Kyoko-chan, of course!"

"No, master! That will be dangerous!"

Suddenly, a silvered hair boy and another black-haired showed up.

"Great, why don't we join Judaime!" the silver-haired or Gokudera Hayato said in favour.
"Of course, ha ha," said the black-haired Yamamoto Takeshi light-heartedly.

"Stop! That is not necessary for we mafia! " an earth-levelling voice started.

The attention was drawn to the speaking man, the ninth storm guardian.

"Geezer! Try to understand the tenth's feeling! At least, it's a mafia thing to save your comrade, isn't it!?," Gokudera retorted for Tsuna.

"How dare you retort me, brat. Do you know who I am?"

"Certainly, you are one of the most respectable members of Vongola family, the ninth's right-hand man! And so what? I'm going to be Judaime's"

"How dare you..."

"Stop messing around!"

Everybody turned to the origin of the scold, and, to their surprise, it was Tsuna's.

"We don't have much time..."

"Young master's voice deepens!" said a man.

Then an orange-tinted flame oozed out from his head and his hands. As Tsuna opened his eyes, they were also amber-ish.

Everyone, especially the ninth, was shocked by what happened.

How could an eight-year-old accessed Hyper Dying Will mode without the special Dying Will bullet?

"I sensed it before, but never gave it much thought..." the ninth began.
"Ninth?"
"This boy has an overwhelming power."

Thereby, finally, Tsuna, Gokudera, Yamamoto and other four bodyguards were allowed to rescue the girl and find out more about a possible enemy who intended to harm their heir.

At the site of the incident, a group of children, including Kurokawa Hana and Moshida (in this AU, Kurokawa is the elder sister of Moshida) along with Sasagawa Ryohei and Kyoko, survived but stranded in a compartment.

"Moshida-kun, Moshida-kun, are you ok?," Kyoko tried to bring him back to consciousness.

"Wanna eat Vongola spaghettis..." murmured the boy in his dream.

"No hope to the extreme, huh?" said Ryohei.

"What are we going to do? My mobile was squashed in the explosion. How can we call the rescuers here?" said Kurokawa

" no idea, but have to wait to the extreme!" shouted Ryohei.

"Stupid! We will have become smoked meat by then!" said Hana coughing.

The smoke was everywhere, blurring their vision.

"There are still some brats left here?" a voice emerged.

"Who is that!?" Hana shouted back.

"Sadly, one of you has to be the Vongola heir, so we have to kill all of you..."

The children only gulped, closing their eyes and waiting for their last moments tensely.

1... 2... 3...

...?

But as they opened them, they were engulfed by an orange-tinted flame that simply melted the gun of the enemy.

"What is happening?," asked Kyoko.

"Dunno. But we're saved to the extreme!"

But the smoke was too thick for them to see anything, but they felt minutes later that the flame died down.

"Stop there, Fabiano! I don't want to believe that you have betrayed the tenth!"

The man laughed crazily,

"It's too late, your Vongola Decimo was dead!"

Gokudera laughed mockingly in answer.

"The great Vongola Decimo is right in front of you."

"What!?"

The brunette fired more flame in his right hand, saying "I won't forgive anyone who try to harm my family!"

The enemy was temporarily stunned but then laughed eerily out of sudden,

"ha ha, only seven people here? Not to mention three harmless brats. You will be erased from this world soon! Go and get them my men!"

A group of black-suit man started firing at them.

"I say, I am not a brat!" bursted out Gokudera, throwing rains of dynamites at them.

"Sorry, but we are not just any brats," agreed Yamamoto, swinging his sword and knocking the enemy unconscious.

Other bodyguards were more skilled than those men, and soon the enemy's men were all knocked down.

"Impossible! My men couldn't be knocked by a few brats and a few Vongola's bottom men"

"We are not bottom men! We are carefully chosen bodyguards of Sawada Tsunayoshi," said one bodyguard

.
The enemy bursted out in laughter instead," ha ha ha. if it all came to this. Let's kill everyone here!"

But before he could do so, Tsuna flew to him, again, to everybody's surprise, and knocked the man away down the cliff.

Tsuna turned to everyone and declared impressively

"I am going to be the master of all mafia!"

Everyone was stunned. Such a powerful boy!

They were going to hail and shower him with praise, but Tsuna suddenly passed out and fell to the ground.

Thud!

"Tsuna!/ Tsunayoshi-kun!"

As one bodyguard picked him up, the flame disappeared from his head.
"So he just returned to normal~" said another man, leaving everyone disappointed.

(The children on the train? They were saved by the rescuers called by Vongola.)

4 Years later...

"Judaime! Aren't you going to take an escort with you?" asked a silver-haired teen.

"No, I would be hated if they know I am a mafiaso!" a certain brunette said, irritated.

"Do not take a train! Have your chauffeur drive you there! It's dangerous!"

"It's alright. I'm 14 years old, anyway."

"Also, the ninth would like you to attend a general meeting this evening..."

"Stop that! I said I won't be a mafia boss or anything! I would rather be just a normal moral citizen!," replied Sawada Tsunayoshi in anger, finishing tying his shoe laces and heading out for his middle school.

As the grand crystal door was slammed, a black-haired teen appeared "ha ha ha, as denying as always, Tsuna!"

"What's good about that!?" asked Gokudera irritably.

Yamamoto suddenly grew solemn, " hey, do you remember?"

"What?"

"Four years ago... That incident..."

"Of course! He really showed the promise of being our tenth!"

"Well, that's a long time ago... and now our family is in its decline. The ninth is in his seventies, and since then Tsuna has never recalled the incident and always denied his relation to mafia.."

The two men only sighed.

What happened to Sawada Tsunayoshi after the incident?

To be continued...

How was that?
I am a fan of both KHR and NNM, and found some overlapping ideas between them, so I decided to write it out. Please review and give more suggestions! Any advice and encouragement would be appreciated!

I am thinking of using Tsuna's dame-ness out of his HDWM in place of Rikuo's limitation in his human form ;).
The story of how Gokudera and Yamamoto become Tsuna's guardians would be in omake.
I guess you could make out which characters in Nurarihyonn no Mago they represent. Yes, Gokudera = Zen; Yamamoto = Kubinashi; Ryohei = Aotabo; Kyoko = Kana; Moshida=Kiyoshi; Hana = ?

See you next chapter :)!
