Thanks for the reviews.

I really appreciated it.

Sorry for the very late update. Assignments and projects just keep raining down and the fact that the test just finished the other day ago. Even my laptop was destroyed by a certain somebody, and thanks to that I can't do any updating.

Please read and review.

Please tell me any suggestions that you might like to make the story more interesting. I'll try to place it in the story…

Sorry for the late update...

When I was in my room, I headed straight at my bed and sighed.

"Giotto, give me a reason why wouldn't I punish you." I said to no one.

"Well, I'll give you some ice cream. Not some ordinary ice cream, but the one which was only done every four years." Giotto told me proudly.

"You mean it?" I asked excitedly. I was really looking forward to it but since I was in a tight schedule, I didn't found any time to order some for me.

"Yeah... But promise that you wouldn't do anything to me, okay?"

"Unn..." I quickly agreed.

He gave the treat at me.

"Be sure to sleep right after you finished eating that, alright?" He said.

I just nodded my head while I scoop the delicious dessert and placed it in my mouth.

"Oyasumi, Tsuna."

(Normal POV)

It was supposed to be a quiet Saturday before two figures started bickering with each other while eating their breakfast.

A five year old boy named Lambo took a piece of bacon from a brown haired boy's plate gracefully, the moment the boy closed his eyes for a second.

When Takeyoshi opened his eyes, he shouted immediately.

"You damn brat! What the hell did you did to my food?!"

"Lambo-sama doesn't know what you're saying." Lambo said childishly while taking another bite from the stolen piece of food.

"Why you stupid brat!" He stood up from his seat and was about to punch the baby when the woman in the house entered the room from the kitchen with a plate of chocolate cake.

"My! Take-kun! What are you doing to a sweet and kind child like Lambo?" Her eyes were covered by her bangs. She caught sight of his youngest son's clenched hands a few inches away from the cowering child.

"K-Kaa-san…" He dropped his hands to his side.

"…" He received a glare in return.

"E-Eto… A-Ano… I-I was just p-playing with the damned brat- I-I m-mean Lambo. Y-Yeah that's right! I was just playing with Lambo." Takeyoshi stuttered.

"Is that true Lambo-chan?" She looked down to the five year old kid who was crying.

"Mama, Dame-Take was about to punch Lambo but he froze the moment you arrive. He's also always insulting the cow." Reborn interjected as he took another sip of his expresso made by the greatest hacker in the world.

"Take-kun…" Dark aura started to gather in the room.

(Normal POV)

"EXTREME!"

"SHUT UP TURF TOP!"

"GYAHAHAHA BAKA-DERA!"

"WHY YOU!"

"MAA~ MAA~"

"Herbivores… Shut up or I'll bite you to death."

"Bossu…"

"Can someone explain how did my office turn into 'this'?" Our hacker asked with voice filled with venom. He's emitting murderous aura while pointing at the pile of garbage- I mean his pulverized room.

"…"

"I only went out for five minutes and this is what I would get... Explain now!" He ordered.

"…"

"Chrome."

"H-H-Hai!" She stuttered.

"Let me see what happened… You better not change it. I can feel if you're going to let me see your memories or another illusion." He walked out of the room, towards the other which was located at the other side of the place.

Chrome followed, sighing in relief because she won't be able to face his boss' wrath if she'll do her job correctly. She knew that her boss was a very kind hearted person but if the hacker was mad or pissed, she knew that hell would break loose.

xXx

Time skip: A few hours later

(Normal POV)

"Chrome, could you please create an illusion of Mukuro?" Tsuna asked the pineapple haired girl.

"Hai, Bossu."

Mist started to leak from the girl and being gathered by her side. Little by little the mist was forming into a shape of a man.

"Kufufufufu… Tsunayoshi, could you tell me why am I not still supposed to get my revenge?" An eerie laugh was heard.

"Mukuro-sama, boss is still in a bad mood, so it would be better if you'll bring that topic later." Chrome whispered softly.

"Kufufufufu… My dear Chrome… There's no such thing as a bad mood in my vocabulary so I'll do what I w-" He stopped talking right after he turned around and saw his fellow guardians in a bad shape… tattered clothes with fresh blood and a few wounds covering them.

"Chrome… Maybe… You're correct." He finished.

"Now, could we already finish this meeting? I don't have all the night to wait for all of you to settle down. We already wasted the whole day because of what you did." Murderous aura was being emitted by the brunet.

"J-J-Judaime… Your cake." Gokudera stiffly walked to the hacker while holding the box in front of him.

Tsuna glared at the silver haired boy when he stood up but after he heard the word cake, a bright smile replaced his glare.

"Arigato, Hayato." He took the box and placed the cake at his plate made by his own illusion and took a bite.

"Anything for Judaime."

"Tsunayoshi… You did not call out for a meeting just for us to watch you to eat a cake, right?" Hibari asked after a minute of watching the brunet.

"Gomen…" Tsuna said and placed his cake aside.

"Just finish this meeting already." Hibari sighed.

"The Sleale Famiglia is moving too fast." His honey colored eyes turned into a sunset colored one.

"We already know that to the EXTREME…" Ryohie yelled.

"And the fact that they are also forming alliances with different small famiglias all over the world." Takeshi followed.

"But did you know what their goal is?" Tsuna asked.

"No, Bossu."

"Gomen Judaime… I failed as your right hand man." Gokudera started to bang his head into the floor.

"Takeshi." Tsunayoshi eyed the black haired man.

"Hai~ Hai~ Gokudera, don't be such an… an… What's that word again?" He wondered.

" An IDIOT." Lambo whispered, emphasizing the word idiot as he snickered.

"Yeah, that's right. Don't be such an idiot." He grinned.

Right after the silver haired man heard that the raven haired boy called him idiot, he immediately glared daggers at the other and started to recite every colorful words that he knew.

"Hervivores…"

"Kufufufufu… The birdy is now going to run wild." Mukuro smirked.

"Pineapple… "I'll bite you to death." Kyoya glared.

"That is if you can, birdy."

The raven haired boy who was holding a pair of tonfas stared to lunge his attack at the pineapple haired boy who was dodging his attacks gracefully.

"Kufufufu… You're losing your touch, birdy."

"You really wanted to be bitten to death, pineapple."

"Everybody's so EXTREME! Let me join to the EXTREME!"

"Bossu…"

"Tsuna-nii…"

Murderous aura started leaking from the small figure who was sitting at the couch alone. His eyes were telling something… something that goes along with 'shut up or you're dead' making the other occupants of the room to freeze on the spot.

"Could all of you get back at your seats before I plan to give you something that all of you are asking me?" Tsuna smiled. He smiled a sickeningly sweet smile which made the others to stiffen.

Right after they heard the brunet spoke, in less than a second, all of them were already seated at the seats. Their weapons magically disappeared.

"As I was saying, do you know what their goal is?"

"No… We don't know, Tsunayoshi." Mukuro said.

"Would you like to know why?" Tsuna's voice was serious.

He received nods from the seven people present in the room.

"It's to make Takeyoshi the Vongola Decimo."

"…"

"…"

"Kufufufu… Tsunayoshi, let me ask you again, why are we not allowed to kill that pathetic excuse as a person?"

"Mukuro… How many times do I have to tell you that, if we kill him while he still have not commit anything serious, the Vindice would take their move resulting for the Sleale Famiglia and their allies to create another war that would be recorded in our history… But if he did anything the Vindice would help us right on the spot…"

"Judaime… Why would they gather just to make that stupid the boss?" Gokudera was the one who was first to snapped out of his daze.

"That, Hayato is for all of you to know tomorrow… or should I say four hours from now."

"What do you mean by that Tsunayoshi?" Hibari asked.

"Byakuran sent a notice an hour ago that he would call for all the boss present at the meeting that I called a week ago… Looks like he discovered something through his parallel self."

"Tsuna-nii…"

"Lambo, you could take your sleep now while we make our way towards the Italy…"

"Nee~ Tsuna… Did you say Italy?" Takeshi asked.

"Yes, I did."

"…" Silence filled the room.

"Is something wrong?" He asked innocently, not knowing why the others are giving him an incredulous look like he was insane.

"Bossu… We need twelve hours to travel to Italy…" Chrome said while fidgeting.

"Don't worry about that. By the way… Kyoko, Hana, Haru… I know that all of you are here. And I also knew that the three of you would jump in right after a close my portal." Tsuna sighed.

"So, even we can't hide from you Tsuna-kun…" Kyoko was the first to appear.

"Of course, you can't… Even Reborn can't hide from me… Right, Reborn?" Tsuna stared at the hanging painting at the wall.

"Tch…" Reborn jumped out of the painting towards the soft fluffy chestnut colored hair.

"Is there anybody hiding here to the EXTREME till now Sawada?" Ryohie asked.

"Hmm… Maybe there is but maybe there's none… It's for you to find out later…" The brunet said cutely as he started to pour black colored flames out of his hand, gathering right in front of him.

"So this is…" Reborn was interrupted.

"Flame of the Night." Mukuro said, making the hit man irritated.

"I bet that the meeting would make all of us speechless, right, Tsuna?" Hana asked.

The small teen walked toward the black portal and gestured the others to come and follow him.

"It depends on your mental strength… Ohh… I remembered… After the meeting we'll meet up with Mukuro and support him." Tsuna walked through the dark fathomless place.

"Hahi! Tsuna-san, we already thought up about that, so we already restock our weapons earlier." Haru said enthusiastically.

"Hahi-onna Urusai!" Gokudera shouted.

Right after they started arguing, a black flame lit up near the brunet, showing another of his acquaintances, Jager.

"Tsunayoshi, I was told by Bermuda-sama to inform you about the Vindice would start the attack in a few hours." He said, making the place's noises die down.

"Jager-san, tell Uncle Bermuda to wait for us to arrive… We just have a meeting to attend to."

"I see… I will… Well then, see you later." He vanished.

"…"

"Tsuna… Since when did you have the ties with the Vindice?" Reborn asked irritatedly.

"Four-hundred years ago… I guess…" He tilted his head cutely.

"Why didn't you tell me anything?"

"You didn't ask me."

"Kufufufu… Tsunayoshi, since when did you asked for the Vindice for help?" Mukuro stared emotionlessly at the back of his head.

"The moment I heard that you found them… And I don't want to go through all the trouble in getting you out of the Vendicare for the second time… Especially not now. We still haven't finished taking care of our problems now..." He sighed.

"I understand... But why of all the groups in the mafia, why the Vindice? You of all the people should know that I had a little history with them." Mukuro pouted a little.

"Mukuro-sama, if we are allied to the Vindice, we won't get into too much trouble." Chrome said.

"Anyway... Let's just go faster at the meeting place. I bet Byakuran really discovered it." Tsuna told his company.

xXx

(Tsuna's POV)

We arrive at the meeting place that Byakuran had told us.

The place was deserted. There was no soul in sight, as I suspected. They wouldn't let any boss in. Only the qualified ones are the only who are worthy to attend the meeting.

"Hahi! Tsuna-san." Haru called me.

"Yes?" I answered her.

"Why is there no one present in here?" She told me.

"Now that you mention it... We're the only ones here." Kyoko looked around the corner.

"Since probably we used my portal to arrive here, at the exact location and knowing Byakuran... He would definitely set traps and puzzles on their way here, to know who the ones worthy in knowing the truths are."

"Tsuna, how many mafia bosses do you think would arrive here?" Yamamoto asked curiously.

"Exactly six, including us and the Milfiore." I declared as I let my own mist flames to create an illusion around me.

After I gestured the pair with pineapple hair styles to cover themselves with a barrier for the group not to be seen, a group of people was heard throughout the entire room.

"Ushishishi... I'm the first, peasants. Now congratulate me, the prince." A blond who had a large creepy grin walked from the door.

"VOIII! WHERE THE HECK ARE THE OTHERS!" A silver haired man shouted as he swung his sword dangerously.

"Why am I here? I won't get any money from this." A baby wearing a mantle which covered almost every part of his body sighed as he floated through air.

"Maa~ Mammon, Don't forget the boss would pay you later~ I think its $50 an hour..." A male with a very unusual colored hair said as he reached for the baby but instead he received a swift kick on his face.

"It's $100000 an hour! You idiot!" The baby shouted.

"VOIII! Nobody gives a damn about your money Mammon!" Shouted he one who was wielding a long sword yelled.

"What did you say? Money is the greatest thing which existed in the world!" The baby retorted.

"Ushishishi... If money is the greatest thing in the world then I'm the greatest prince which existed in the world." The blond declared as he continued to laugh eerily.

"No one gives a damn about you too, creep." A black haired man snorted.

"Did you say something, loyal dog?" The tiara wearing teen grinned evilly.

"I said CREEP! P! And I'm not a loyal dog!"

"You're really asking for it." Knives suddenly appeared out of nowhere in the blonds' hands.

"Mou~ Minna~ It's not a good thing to fight here~ Especially since the greatest hacker in the world is already here~" The sunglasses wearing man pointed at the corner of the room where I was staring at them.

"Ushishishi... Even I did not notice him there."

"So he really does exceed our expectations. No wonder the Boss is interested in him."

"If I'll be able to requit him, maybe the Boss would pay me ten times my salary now."

"VOIII! Don't even think about that! That runt won't accept your offer."

"Everyone~ Don't be rude to him."

Watching the group with interest I, the greatest hacker in the world opened my mouth and said.

"Don't mind me... I'm just here to observe. Ohh... The next group is here."

The whole group stared at me for a moment and towards the door.

"Hime-sama... Please wait for me. Don't just go on your own. Who knows what would be in the place. There might be more traps." The voice echoed, together with little pants.

"Don't be silly Gamma. There's already the sign 'Welcome to the Meeting Place' and 'Congratulations on Arriving at the Place." A female voice was heard.

"Hime- sama, then what would you say about the banners that have 'Congratulations for Being Arriving at the Exact Time' 'Welcome to the Room' and others where we found ourselves being a target practice of some robots, walking to a room filled with poisons, or when we were being thrown by some acids." The man who was Gamma sighed.

"Mou~ Gamma, those banners and these signs are two different things." The woman who was the boss of the Giglio Nero Famiglia, Aria entered the room and stopped walking.

"Hime-sama, why did you stop?"

"Ohh... I think we got to the wrong place Gamma."

"Huh? What do you mean?"

There's no way this is the meeting. The Varia is the only group in here."

"Aria-san I'm also here." I waved at her.

"Ohh... Sorry Cielo-kun. Anyway why are you here?"

"Observing."

"I see"

"So this is the place?" Gamma asked.

"I'll answer your question if you pay me a million dollars." Mammon said as he floated his way near the man.

"Ushishishi… Why do you think the Varia is here for? Are you expecting a prince like me to attend a meeting just for nothing?" The self proclaimed prince said.

"Bel, you're not going to take your salary for about a month because of what you did." The hooded baby smirked evilly as he eyed the blond who spoiled his million dollar plan.

"Three…" I started counting as I felt two pairs of shoes stepped in the other room beside the one that we are currently at.

All heads turned to me as they heard me say the number three.

"What is the greatest hacker counting for?"

"Who knows? Maybe he's bored?"

"Hey! Are you saying that we are boring?"

"Two…" I continued counting.

"Umm… Cielo-kun, is there something going to happen?"

"Cielo?"

"One…" I ignored them all and when I finished my counting a new pair of voice echoed through the room.

"Wait Adelheid!" A red haired boy panted as he collapsed at the cold floor. A recognized his as the Shimon Decimo, Enma.

"Hurry up Enma! Those traps are like nothing. You're really are getting pathetic this last week. You can't even do a five kilometre run in one hour without panting. Maybe I should give you a new training schedule?" A female voice scolded at him.

The two of them continued their conversation, not realizing that the room was occupied by few of the most well known people in the mafia.

After a good four minutes the door in the middle of the room opened, revealing the man responsible for the meeting that was undergoing, Byakuran, the boss of the Millefiore Famiglia.

"Maa~ Only three groups and Cielo-kun were the ones who arrived?" He chuckled.

"Byakuran, you're wrong." I corrected him, as I felt a soft scream a hundred meters away from us.

"What do you mean, Cielo-kun?" Aria gave me a confused stare.

"Six groups will be present here in the meeting including the Millefiore." I informed them with a bored tone.

"But there's only the Varia, Giglio Nero Famiglia, Shimon Famiglia, me for the Millefiore, and you? The meeting would start exactly after a minute." Byakuran gave me a look that said 'Are you really sure?'

"I know… Those two would arrive before the time…"

"Maa~ Cielo-kun~ Who's the two? And didn't you say two?" Lussuria squealed.

"That's right, only two."

"VOIII! But didn't you say that the total would be six groups in here?" Squalo swung his sword towards my direction.

"Ushishishishi… Looks like the peasant hacker has a weakness… He can't even count right."

"Anyway, you'll find that out later…" I sighed as I ignored their questions for me.

"Cielo-kun~ I'm sorry but there's only five seconds left so I'll start now." Byakuran strode his way into the middle of the room as he started to count.

"Five…"

"Four…"

"Three…"

"Two…"

"On-"

'Thump!'

All heads turned at the door for the umpteenth time, spotting the boss of the Cavallone Famiglia, who was very clumsy unless if one of his family members are in trouble.

"I hope I made it in time…" He panted as he tried to stand up.

"Boss… You better need some exercise every day." Romario, his most loyal subordinate, magically appeared near the don's side, helping the latter to stand up.

"Yes, you did make it in time." Byakuran said as he eyed me.

After a minute, the entire group was properly assembled at the room, only waiting for the host of the meeting to start.

Byakuran first looked at my direction and then to the others' places. He coughed a little to attract our attention and when he felt that all eyes are on him, he spoke.

"I know that all of you are wondering why I called out for you and why I placed those traps along the way."

"You bet we did! Hime-sama was almost in danger because of it!"

"Mou~ Gamma… Don't interrupt the boy's speech."

"Gomen, Hime-sama."

"VOIII! Those traps were like nothing!"

"Ushishishishi… I can deal with those things even if my eyes closed."

"Give me a million dollars for every time I pass those obstacles and I won't complain."

"Mou~ Everyone~ Just listen to the Marshmallow guy~"

"Those paths we took were torturous."

"Enma, those were just simple traps… You better have a lesson on traps."

"Boss, don't sleep now. The Millefiore Boss is about to speak now."

"But Romario, I'm sleepy. I'm too tired because of those traps that could almost compete with Reborn. Just remembering that guy makes me shiver."

"Well, Cavallone, looks like there would be hell prepared for you in a few minutes." I said.

"Huh?"

"Well, Cielo-kun~ Varia~ Aria~ Shimon~ The reason I called out for you and let you pass those traps is because-"

"Byakuran… You did know that I didn't pass through those, right?" I interrupted him. I'm just delaying him because I'd like my company to beg for the new information.

"Mou~ Cielo-kun~ But I prepared a special route for you~ You should've passed through it~" He pouted.

"It's a waste of time. Now could you finish your speech now, I'm a busy person, you see?" I told him.

"Alright~ As I was saying… Ohh… Right… The reason why I let you pass through those routes is to know if you're worthy for the information I just got, about Cielo-kun..." He started with an aura that a boss have.

All eyes stared at him, demanding for the Millefiore Boss to continue his speech.

"Tsuna-kun is the only biological son of his mother, Sawada Nana…" He finished.

And everyone in the room stopped their movements. I could even feel that their breathing's stopped, especially the Varia.

I also noticed that the barrier that Mukuro and Chrome created was broken due to the shock.

A few minutes have passed and Reborn was the one who had recollected himself.

"Byakuran Gesso… Are you telling the truth? From my information that I've gathered, Sawada Nana is the mother of the twins… Sawada Tsunayoshi and Sawada Takeyoshi…" Reborn's eyes seek for the truth. I can sense a murderous aura coming from him, directing to a certain boss who was happily eating some marshmallows a minute ago, probably he's already time for waiting their reactions.

"VOIII! Wait a minute! Did you just say Tsuna! Tsuna Sawada! The boy that the Boss likes to have some tea with!?" Squ-nii, the guy with the silver hair was panicking.

"Ushishishi… If that's the truth, it's a good thing that you told the Boss not to come here Levi." Bel-nii said.

"Maa~ If the Boss would know about this… I'm sure he'll definitely throw a tantrum in the whole quarters." Luss-nee shivered.

"Well Levi, I can create a hiding place for you if you want. Just make sure to give me a million for every hour." Viper-nii smirked. He's probably thinking about his new part time job.

"Listen to them now… The Boss told me to tell him every important details and that brat's not important… So nobody would tell that to the boss." Levi-nii started to count the money in his bank account.

"Maa~ if the boss would pay me, I might tell him all about 'this.' I could even give him a 3D effect."

"Ushishishi… Looks like they are having some quite argument." Bel-nii pointed at the corner of the room where Byakuran and Reborn could be spotted.

"Now… Tell me how is that possible!?" Reborn shouted at Byakuran who was clearly ignoring him.

"Ohh… Where did you, arcobaleno came from? Wait, scratch that… Where did you and that group of children came from?" Byakuran pointed his fingers to my friends as he raised a brow.

"Byakuran, I believe that I told you that there would be six groups present in this meeting, right?" I asked him.

"Yes, you did… But what's the grouping here again?"

"You and Bluebell, who was hiding under the table." I pointed at the table at my back.

I saw everyone raised a brow except for Byakuran. I decided to call for her.

"Bluebell, quit hiding if you'd like to have a week of tea with Byakuran alone."

And immediately after I said that, a soft rattle was heard and a blue headed girl popped out of the table.

"Cielo-kun, are you serious about that? I can get Byakuran-sama's tea time together with me for a week?" She asked me with sparkling eyes.

"Well since, Cielo-kun did spot you while the strongest hit man the Varia and the others didn't, I guess it's alright." Byakuran said as he took another bite of his marshmallows.

"The second one is the Giglio Nero by Aria-san and Gamma, followed by the Shimon by Enma and Adelheid and then the Cavallone by Dino and Romario."

"And what?"

"The fifth group is the Varia, Squ-nii, Bel-nii, Luss-nee, Levi-nii and Viper-nii."

"VOIII! Just who the hell are you!"

"Ushishishishi… Only one person would be allowed to call me that."

"Boss' favourite kid is only the one to call me that."

"The other arcobaleno and the boy in the prophesy is the only one who's allowed to call me Viper… Anyone else would pay and since you add nii in it, pay me double."

"Maa~ There's Tsu-chan's cute voice~"

I sighed as I dropped my illusion and stared at Luss-nee.

"Luss-nee, how many times do I have to tell you that my voice is not cute!?" I told him as I puffed my cheeks.

"Maa~ Tsu-chan~ That appearance suits you more than your illusion. You're much cuter like that."

"VOIII! Tsuna, don't tell me that you're really Cielo?" Squ-nii asked me in a tone of disbelief.

"It depends if this is an illusion."

"Is it an illusion, Mammon?" Levi-nii asked Viper-nii.

"He's the real deal. I did not even notice him use an illusion; I did not even felt those kids' presence till they dropped their illusion."

"And the sixth group is me, Reborn, my friends and…" I murmured the last part.

"What?" Byakuran asked me.

"Hey! Just answer my question, Millefiore!" Reborn snapped. I almost forgot that he's still interrogating the white haired boss.

"What question?"

I heard another snap coming from Reborn.

"What do you mean that Tsuna is the only son of Sawada Nana?"

"Tsuna-kun is really the only son of Sawada Nana. That's something that I discovered from some of the parallel world I had been."

"What kind of parallel worlds?"

"The ones that Tsuna-kun is the heir of the Demon King, a world where Tsuna-kun is the purest angel, a world where he is a fairy, a son of a King and a Queen, and others."

"But that's impossible! I already have a DNA test that Iemitsu's really the father of the two."

"You did said it, arcobaleno. Did you even consider having a DNA test with Sawada Nana, their mother?"

"Don't tell me… that-"

"That's right Reborn…" A woman appeared at the corner of the room.

xXx

I'm really sorry for the very late update…

Anyway I just decided to cut the story there because it might take like forever if I tried to add some more…
