~Flashback~
~What really happened in the Inheritance Ceremony after Tsuna was named the official Tenth Boss..~

Tsuna and his Guardians went to their table at the very front,just down from the stage and took their places. Just as Tsuna is about to sit on his chair,he look at his classmates and give them a soft/sadistic smile that send shivers down their spines.

"Oh God,we're doomed."--the students nervously thought.

Tsuna smirk,completely knowing what his fellow classmates are thinking.

"Excuse me for a moment."--Tsuna said

"What's the matter,Tenth?"--Gokudera

"Oh,nothing. I just want to check on our classmates and see if they are alright."--Tsuna

"Heh..Do as you please,Tenth."--Gokudera said

"Well then,you can go ahead and eat without me. I'll have some fun over there."--Tsuna said as he walk towards the students' table. The Guardians (minus Lambo) just smirk evilly as they glance over their paralyzed classmates and juniors.

The students stiff on their seats as Tsuna draw near.

"So,everyone.. How is everything so far?"--Tsuna said,smiling

"U-U-Uhm.."--Miyuki

"You're the Heir of Vongola?! The one the Ninth talked about?! You've gotta be kidding me!!"--Daisuke

"Hey Daisuke! Lower your voice!"--Miyuki

"Well, I am.. I am the former Heir.. As you've witness just a moment ago,I'm the Tenth Boss of the Vongola now. And,that means I now own the La Arsella Societa or the Vongola Business Companies,Aoba Daisuke-kun.."--Tsuna

"No way.."--Daisuke

"Yes way. So,back to my question earlier. How is everything so far? Is it too much for you?"--Tsuna said

"Yes,it is..Tenth.."--Nezu-sensei,speaking for the first time

"Oh,really? I'm sure you'll get over the shock in a moment,considering how bold the most of you are. Since you now know the truth,I guess I don't have to act like a No good now."--Tsuna

"A-A-Act like? W-W-What do you mean?..Tenth?"--Rukio said shakily

"Oh,failing in class,slipping every time, stuttering like an idiot,screaming like a girl and being a No-good in the last 2 years are all just acting and a part of my play. This is the real me...I'm a Boss..Nanase Rukio-kun."--Tsuna

A thick fog of silence loom over the students as they try to digest what they just heard.

"Anyway,I'll deal with you all some time. I shall answer your questions on that time. For now,enjoy the celebration. Excuse me."--Tsuna said as he went back to his table where his Guardians are waiting

"Tenth.. You're the most sadistic Boss of Vongola in history."--Gokudera

"Thank you for the compliment, Hayato."--Tsuna said as he sat down. A (sadistic) smirk graze his lips

"Ahahahahaha,it'll be fun to watch you deal with them,Tsuna!"--Yamamoto

"Really? I'm looking forward to it too."--Tsuna

"Finally,brother..Named official at last."--Enma,who suddenly appeared out of nowhere,said.

"Hey,Enma.. You're late,brother."--Tsuna

"Sorry,the meeting at Venice took longer than I thought it would."--Enma

"I see. Your Guardians?"--Tsuna

"Good evening,Decimo. We apologize for taking too long and missed your Inheritance."--Adelheid said. The other Earth Guardians followed suit.

"No,it's fine it's fine. Take your seats,everyone."--Tsuna

Enma sat on the seat in Tsuna's front and his Guardians followed him. Each sat on their seat and face their same-element/flame fellow Vongola Guardian.

The guests,of course are enjoying themselves. Everybody is having a blast well,almost everybody. The students however,can't take everything so easily.

"All hell break loose when the real Sawada Tsunayoshi emerged from the shadows..He isn't the same now,he's not the Dame-Tsuna we used to know..He's the Decimo of the Vongola.."--the students fearfully thought.

Now that they finally realized, they couldn't dare to imagine what Tsuna will do to them. Surely,Tsuna won't forget their past disputes.

"Well,let's just hope that death will turn itself backwards."--Nezu-sensei
.

"Tsk. Tsk. Tsk. Tsuna,you didn't wait for me. That's not fair,I wanted to see their freaking hilarious reactions too."--Enma

"Now,now brother,don't be upset. I'm sure there's more of those for tomorrow. You know what I mean,Lord Simon Decimo."--Tsuna

"Heh.. Brilliant idea,Lord Vongola Decimo."--Enma

The Vongola Sky Flame Guardians and the Simon Earth Flame Guardians look at each other then at their Bosses.

"Oh no..Here it is,the Sadistic Duo."--the Guardians all thought
~~~~
~The next day..~

A smile decorated Tsuna's lips as he stroll the hallways straight to the Dining Hall. He wears a black suit again since it's a casual tradition for the Vongola Bosses to wear suits at work.

When Tsuna reached the Dining Hall, he heard joyful giggles and laughters from inside, that cause his smile to grow wider.

"Good Morning,Young Master Tenth. Everyone is waiting for you,please proceed."--the butlers at the doors greet happily and bowed as Tsuna walk pass them.

"Good Morning to you too,Sireo and Conceto. Thank you for the greeting."--Tsuna

"You're always welcome,Young Master Tenth!"--the butlers

Tsuna smirk when the happy noises died down as he sat down his chair in the head of the table. The Guardians and the Feroce Terzetto stand up and bow.

"Good Morning,Tenth!!"--As usual, Gokudera is the loudest in greeting Tsuna.

"Good Morning,everyone. Please sit."--Tsuna said as he motion towards the seats.

The Guardians immediately obeyed and sat back to their seats. Tsuna snap his fingers and the chefs serve them their food. Just as everyone start to eat,the Dining Hall doors open and Enma enter together with his Guardians. Like Tsuna, Enma wears a black suit.

"Good Morning,Enma and everyone. You're just in time for breakfast,join us."--Tsuna said as he smiled at the Simon Family.

"Kozato?! Why the hell are you wearing a suit too?! You're nothing like an authorized person to wear something so elegant!!"--Rukika suddenly burst out the words that aren't supposed to speak while the Simon Family is in view.

The Simon Family devilishly glare at Rukika and is about to assault her for insulting their Boss,but Enma wave them off and motion for them to sit down which they reluctantly obeyed.

"Tsuna,I think I want to see those reactions,now."--Enma said smirking at Tsuna,who instantly get his point.

"Junior Class 1-A and especially Nanase Rukika..I like to introduce to you,the official Tenth Boss of the Simon Family and the owner of the La Terra Societa, Enma Kozato. And,here are his Guardians."--Tsuna

1...
2...
3....
4.....
5......

"WHAT THE HELL?!!!! KOZATO OWNS THE LA TERRA SOCIETA AND HE'S A BOSS TOO?!!!!!!"--screams that cause the earth to shake.

"No way.. The La Terra Societa is the second most biggest company next to the La Arsella Societa, which is the Vongola Business Companies..you're kidding us.."-Mochida

"Seriously,Mr. Mochida? Do I look like I'm kidding you?"--Tsuna

"N-No.. It's just..u-uhm...It's all too much for us. First,us knowing you're the Vongola Decimo and the owner of the La Arsella Societa, then now knowing Kozato is a Boss too and the owner of the La Terra Societa. "--Mochida said almost straight. Tsuna just smirk at him.

"Guess so."--Tsuna

Enma's smirk grow wider as he stroll over to where Rukika is standing and stop just a few inches away from her. He gently grab the girl's chin and made her look at him.

"I'm nothing like an authorized person, huh? You sure talk a lot. Try putting some thinking on that mouth of yours and don't speak like you know everything."--Enma said in monotone voice.

Rukika unconsciously drop back to her seat as Enma sit on his chair. Tsuna motion for everyone to eat,to lessen their shock.

"Now,for some important matters and to clear things out,you still have two weeks to spend here before returning back to Japan on the last day. I'll grant you permission to do whatever you want, unless you have a butler or two to guard you. I strictly forbid all of the students and teacher..to go anywhere beyond the Mansion and the town. I will only grant it if my presence is intact or any of my Guardians. Enma can also have the authority to watch or guard over you. And,while you're all still here,I expect you to follow the rules and the regulations or else you have to deal with me. And,I'll tell you now,you don't want to mess with me.. One more thing,ask permission to any staff of the Mansion if you want to use any thing of sort..Understand?"--Tsuna said in serious voice.

The young Don just smiled as he received a series of nods from the students and Nezu-sensei. He look to Enma,who's also smiling..Just then,Fuuta,Lambo and I-pin came entering the Hall,crying and wailing.

"UWAHHHHH!! TSUNAYOSHI-ONII SAMA!!!!"--the kids wailed as they clutch on their big brother,who immediately aided them. A dangerous frown graze his lips.

The Guardians of both Sky and Earth and also Enma shiver in fear. They instantly know what happened. The children only call Tsuna,"Tsunayoshi-onii sama" when they are hurt,offended,assaulted,teased and when Tsuna hears this,the one who cause any of the wrong words will wish he never carelessly uttered that word. For they will taste Tsuna's sadistic torturing wrath and it's not very pleasant to see.

Right now,Enma and the others are silently praying for the person who will soon be the victim of the torture that will befall to him/her.

The kids continued crying until Tsuna speak to them.

"Shhhh..There,there. Stop crying now,you three. Tell me what happened?"--Tsuna

At that moment,Kentaro burst in,holding a stick firmly. When the kids saw him,they cower in fear and Tsuna's expression become even more darker than a monster for he knew already the reason why. Red marks are very visible in their backs and this makes Tsuna very furious.

"T-T-That onii-san over there hurt us with that stick of his!"--Fuuta said,pointing at Kentaro.

Uh-oh..One..

"A-A-And he teased us!! Calling us rats and cowards and fools!!"--Lambo

Two..

"A-A-A-And he said that we're just adopted so we don't have any parents."--I-pin

Okay..That reached the peak. Three..

Tsuna smiled at his siblings and motion for Haru and Kyoko to take care of them while he takes care of Kentaro. Kentaro,on the other hand,realized what he had done and now shivering in fear.

"Mukuro! Chrome! Use your illusion and bind or tie him in a long stake. Now!"--Tsuna commanded as he glare at Kentaro.

"Yes,Boss!"--Chrome

"Kufufufufu, this will be fun to watch."--Mukuro

When the two illusionists are done tying up Kentaro,they went back to their seats as Tsuna enter Hyper Mode.

"What's going to happen?"--Miyuki

"You just watch,Pres. and you'll know soon."--Yamamoto

Tsuna sadistically smile at Kentaro and lit his X-gloves. Sky Flames burst out wildly as the students' jaws drop.

"Let's have a little chat,Aoyama Kentaro-kun."--Tsuna

*gulp.* That's Kentaro's only response as the Sky Flames form a circle around him.

"Say,do you know the Mafia?"--Tsuna ask and Kentaro nodded as well as everyone. They fear the Mafia because of its influence in crimes and in media. It is said/known that the Mafia is very powerful when it comes to fighting,that the governments decided to leave them alone.

"And do you know why,we are called the Vongola Family?"--Tsuna ask again but Kentaro just shrug.

"It is because the Vongola Family is a part of the Mafia and to let you know,the Vongola Family is the strongest Mafia
Family among all the other families within the syndicate.."--Tsuna said in a serious tone.

The students felt their souls leaving them, when the information sink in.

"You know what that means?.. I am no ordinary Boss of a famous Business Company...I am the Tenth Generation Mafia Boss of the Vongola Mafia Family.."--Tsuna

The students nearly faint as they watch Kentaro holding back both of the shock and fear.

"You know.. Insulting me many times is nothing to me..But,crossing the line like insulting my parents is unforgivable like Rukio did."--Tsuna said as his gaze turn to Rukio,who whimpers..

"To tell you the truth Rukio,I wanted to torture you that time,if it hadn't for Grandfather Timoteo's interruption."--Tsuna said as his gaze return back to Kentaro,who's beginning to wither in pain because of the heat pressure from the Sky Flame.

"Haha..Now,insulting and hurting my siblings are also crossing the line, Kentaro.. So I hope you prepared yourself for the consequences that I,myself will give to you."--Tsuna said as he ignited his Ring and the Sky flames around Kentaro grow and began to dance wildly.

Tsuna smirk as red spots are beginning to sprout from Kentaro's skin while the poor boy started screaming. After a few minutes,Tsuna extinguished his Flames.

"So,how does it feel to be barbecued? Amazing isn't? Want another round?"--Tsuna

"N-N-No!! Please!! I-I-Im sorry!!"--Kentaro shouted,finally be able to use his voice.

The students shrank on their seats and whimpering the whole time while the Guardians are smirking on what's happening before them..Clearly,they're enjoying the show.

Tsuna's smirk grow wider as he approach Kentaro and positions into a stance the Guardians are completely familiar of.

"Shinuki no Zero Chiten Toppa: First Edition (Dying Will Zero Point Breakthrough: First Edition)"--Tsuna said as Ice start freezing Kentaro's body.

After completely freezing Kentaro,Tsuna turn to his Sun Guardian.

"Ryohei,after 15 minutes,unfreeze him using your flames."--Tsuna said as he shift his gaze to the students,who are traumatized.

"YES BOSS!! TO THE EXTREME!!!"--Ryohei yell

"Now,you know why you shouldn't mess with me or underestimate me..Junior class 1-A..."--Tsuna said as he smile and look at his watch..

"I must excuse myself now.. I have a meeting at Rome in exactly 9:30 am.. Hayato,come with me. Takeshi and Kyoya,you two are in charge of everything while I'm gone."--Tsuna said as he walk out of the Dining Hall with Gokudera behind him..

"You can count us Tsuna!"--Takeshi shouted

"Hn."--Kyoya said as he disappear.

"Now,everyone finish your meals,so you can do whatever you want afterwards. but,remember what Tsuna said about it or else you dont want to mess with him and be like Kentaro over there."--Yamamoto said as he continue to eat.

The students quickly spoon down their food,overwhelmed with fear of the young Vongola Decimo's Dark side.
