Be careful what you wish for

Summary: Be careful what you wish for because you might just get it. Tsuna wonders out aloud. Reborn hears it and an idea formed on his demonic mind. Tsuna disappeared.

Previously…

"Shit's going down, boys. Prepare for war. I want that blueprint."

"When do we strike, boss?"

"We strike at dawn, tomorrow."

Giotto jolted up with a cold sweat lingering on his forehead. Something isn't right. Hell, nothing is right the past few days. His sea-colored eyes darted back and forth as he scanned the room frantically for any sign of anomaly and sighed when he found none.

A grunt came from the couch not far from his bed. His eyes fell on the awaking form of his Cloud. "What the fuck are you doing…?" he asked with a yawn escaping his lips. "It's fucking three in the fucking morning."

"Something's not right." He said, opening the black drapes slightly. It was still dark outside, the sun lazily making its way up to its throne. He closed his eyes for a second and focused on using his senses.

Primo stayed in that position for a while before he went to his closet to change. Alaude merely raised a snowy brow at his lover's antics. "There are people in the forest."

"So? Maybe they're lost or some shit."

"They're hostile, carrying heavy artillery and have some serious firepower."

"Hn," was all he replied before wordlessly leaving the room probably to prepare for the incoming battle.

After getting dressed, Giotto went to his Guardians' private quarters to wake them up one by one and inform them about the current situation. As soon as they are prepped and ready to go into war, they all assembled to the briefing room to discuss what they'll do.

"Where is our guest?" asked G with distaste.

"He said he was going to visit Talbot for a reason unknown to us." Giotto answered distractedly while looking at the map of his land.

There was silence not until Lampo spoke in all his lazy glory. "So what are we going to do now, Primo?"

The First Storm Guardian scoffed, "Of course it's simple you lazy brat! We'll bust their heads in and kick their asses to the ground."

"Ah that is quite the game-degozaru~ It must be fun~." Asari laughed, not really knowing what G implied.

"Yeah it'll be fun after I crushed your goddamn head on the fucking floor, your fucking brain splattering on the white tiles and blood flowing out of your skull then you'll die from blood loss and fracture... Yes, that'll be fun indeed." G grinned manically as dark and psychopathic aura surrounded him.

Lampo inched away from his seat and scooted closer to Alaude who kicked him back to G's side with a fierce glare. Knuckle clutched his bible closer to his chest. "May God have mercy on thy soul."

"I have a feeling it's only a matter of time before they strike. We must be prepared. Put our men on high alert but don't let them be obvious that they know that there is an ambush. I want our enemies to get the feeling that they took us by surprise and when they thought they won," the blond paused as he looked at his guardians with a small grin.

"…We'll start our counter-attack." Daemon finished with a satisfied smirk.

The blond nodded with a small smile. "Asari you keep watch by the river. Daemon you're in charge of the mansion that means you're keeping an eye out for Elena and Elise. Alaude you're at the back door. Lampo you are assigned to guard the front gates if some idiot waltzes right into our compound. Knuckle you're going with Lampo just in case. And G, you are to back us up from our watchtower. Got it?"

"What…? I don't want Knuckle to come with me…" The green haired male groaned as he planted his face onto the table.

"Maa, maa~. We all know you could be reckless sometimes, and you're the youngest amongst us so we have to keep an eye on you-degozaru~." Asari beamed at the lord's son.

"Asari's right, Lampo. You have the tendency to be like Alaude," as he said that, Giotto shot his Cloud guardian a nasty glare in which Alaude gladly returned. "…recklessly charging into battle without a plan or something."

The lightning guardian just groaned and scratched the back of his head in surrender. "…Can't say no to you, Primo."

"Let's go." All of them nodded with determined faces.

Tsuna sneakily made his way towards Talbot's hut. He was aware of the enemies that are about to surround the forest and mansion in just a few hours. They weren't able to hide their hostile intentions to his hyper-intuition.

Silently, opening the door, the brunet saw the man working on the portal. "Talbot-san!" He hissed urgently.

"Child," the metal craftsman said as he looked behind him. "What is the matter? It's three in the morning!"

"We have a huge problem." Tsuna said.

Decimo soon told the story of Elise acquiring a blueprint of a weapon of mass destruction from a dying guy that has been running away from his captors and now the mafia that killed the man has their eyes set on Elise.

"Indeed…" Talbot said with a sigh.

"I need you to get out of here, as quickly as possible." The brunet hissed, his eyes darting from left to right.

The craftsman shook his head stubbornly, "I cannot leave, Decimo. I am bound to this place no matter what happens." He released the breath he didn't knew he was holding. "Come Decimo, let us move the portal to a much safer place."

He crouched beside his crafting table and lifted the hidden trapdoor that looked like it wasn't there unless you look at it a second time. "Underground?" Tsuna asked dumbly.

"Ah yes, my workshop is connected to the sewage of the town but do not worry, I have a clean place to store this masterpiece." He cackled lowly before proceeding to descend to the sewer.

The brunet could only scrunch his nose up in disgust. Holy hell this smells a lot worse than Lambo's poop count for a month. Being the strong dame he is, Tsuna carried the machine with an arm around it while he slowly went down the drain. Thankfully, the trapdoor is large enough for the portal.

Rats were running around the empty sewerage. "Careful, Decimo. These rats ain't that friendly to visitors." Talbot said with a wicked grin which caused Tsuna to quicken up his pace.

After few minutes of walking down identical passages, they arrived in front of a dead end. "Here we are." The craftsman announced. The young man just raised an eyebrow at the older man as he watched him press an almost invisible button on the wall, opening up the supposedly dead end and revealing a well lit and well organized room.

"Place it here." Talbot said, patting on the stone crafting table in the middle of the room. Tsuna did as he was told and stretched after accomplishing his task. "Well then Talbot-san I'll be heading out and prepare for the war. Meanwhile, please continue fixing the machine." With that, Decimo swiftly left the room and went back to the surface.

When he exited the hut, he was alarmed when shadows started moving using the darkness as their guide. Keeping his senses and guard up, he moved silently towards the back door of mansion where luckily, no enemies were positioned.

"They're here, Giotto." Tsuna grunted as soon as he entered from the backdoor where he found Giotto standing not too far away from him.

The blond nodded, "Let's get this show on the road. Everyone else is ready."

Knowing that Giotto would get suspicious if he fought with their side with his gloves, Tsuna convinced the First to let him guard the woods.

All members of the Vongola family were on their respective positions, on high alert, their weapons at their hands, trigger fingers getting itchy. As soon as the first rays of sunlight came into view, the Estraneo family started their assault on the Vongola.

Numerous Estraneo family members emerged from their hiding spots and started fighting for the sake of their boss' whims. They took the Vongola by surprise. That's what they all thought.

As soon as they went out of the shadows, the members of the Vongola family began their defense. During their time, rings, boxes and flames were not popular. Family members often use firearms like Tommy guns and the like while the Family's guardians fight with their respective weapons.*

Despite being the underdogs of this war, the Estraneo family proved to be difficult opponents even though they are a normal mafia family. Their fire power is enough to put the First's family on a tight pinch.

Bullets and grenades were raining down on the mansion. "It never ends and it looks like the enemy mafia has so much ammo to spare." Giotto observed while spinning on his swivel chair.

"No shit." Alaude scoffed.

The blond raised a golden eyebrow at his lover. "Shouldn't you be fighting outside?"

The silver head snorted. "Shouldn't you be leading us to win this war?"

"Meh. You guys can manage by yourselves." Giotto drawled, his question left unanswered… not that he mind, though.

Silence befell on the two as they thought of different things. "Where's that kid?"

"Kid? Ah, you mean Tsunayoshi…" He waved a hand dismissively. "He's out at the woods fighting."

"Alone?"

"Yes Alaude. Alone," Giotto nodded his brows meeting in the middle. Why was Alaude asking this instead of wrecking them so-called mafia members outside, he didn't know.

"Y'know… He's like you… but on a different level. I can tell the moment I laid my eyes on the boy." The platinum-haired said, scratching the back of his head, unsure of what to say next. "And I get the feeling that he wasn't supposed to be here."

The other blond's lips tugged upwards. "My, aren't you observant, Alaude-kun?" He teased with a smug grin. "Well, I know I know him but I didn't know where I met him… And I'm sure as hell this wasn't our first meeting."

Alaude opened his mouth to say something but was cut off when he saw the horizon turning a bright orange through the windows. He was sure that isn't the sun rising. It was flames. But as soon as they saw it, it was gone in a flash.

"Giotto-!"

"Sky Flames…" Giotto said breathlessly as his blue eyes gazed into the horizon.

"Could that kid be…?" He was unable to finish his question when he heard the familiar sound of a safety pin being pulled. After a few seconds, he saw a small object land on the floor a few inches away from him and Giotto. He didn't need to look twice to know what that is.

"GET THE FUCK DOWN!" His cloud guardian said as he tackled him to the ground, keeping his head low.

The grenade exploded with a loud boom alerting all of the family members inside and outside the mansion. Smoke was coming out of the windows, and the office was slowly coming apart. The two men were beneath the debris. "O-oi…" Alaude said as he attempted to get up but only to find him trapped. Clenching his teeth in irritation, the carnivore pushed a portion of the wall that fell on them.

He shook the blond who had his eyes and lips shut tight. "Oi you dumbass wake the fuck up! We've been breached." He breathed but got no response from his boss.

"Giotto?" It took him a while to see the blood flowing out of Giotto's skull.

Five minutes before the explosion at Giotto's office…

Tsuna found himself surrounded with heavily-armed men. All of them were intent on killing anyone who gets in their way and that includes the brunet.

"Aren't cha the oh-so-great Vongola Primo?" one of the goons asked with a sneer.

"You're mistaken, sirs. I am just a mere visitor." Tsuna replied with a sickening sweet smile that made their insides turn.

"Cut the bullshit. You're Primo!" another goon roared before coming at him, guns blazing. Tsuna effortlessly dodged the incoming bullets even without going into Dying-Will Mode. This was the fruit of his training under the torture-ship… errr tutelage of the great Reborn-sama.

"Come at us, brat!"

Having no choice, he swallowed two dying will pills. Bright orange flames appeared on his forehead and his Vongola ring transforming into his X-Gloves version Vongola Gear. "Let's go." He announced as his enemies backed away from him.

They aren't suited for close ranged combat so it's natural for them to back away from me. They started to fire bullets at Tsuna who simply knocked the bullets away from him with the use of his gloves. "Tch." He heard a man click his tongue in irritation as he raised his hand, a signal to his other allies to come over.

Out of nowhere, three muscular men appeared, eyebrows creasing. "Oh my," the brunet sighed.

"Just surrender now, kid. I don't want to murder a growing teen like you."

Tsuna flinched, offended. "I'll have you know that I'm already 24 years old."

"Oh? Then I don't have to worry about it." As soon as he said that, the three charged at him, fists enveloped with brass knuckles. The gunners at the far back were doing well on supporting their melee specialists. All Tsuna could do was dodge. If he were to do a counter attack, his enemies can dodge it then the firing squad behind them could manage to land a shot or two on him.

Shaking his head free of thoughts, Tsuna remembered something that his tutor said to him. 'The Dame-Tsuna I know doesn't think. Instead, he just faces his adversary head on.' He couldn't quite remember it well but he was sure it was something along those lines.

He sensed a punch was coming straight at his face. Dodging it slightly – grazing his headphones in the process – he grabbed the arm of the muscle man tightly and used his other arm to break it. A loud crunching of bones made him wince in disgust. The man who had his arm broken collapsed on to the ground, another hand supporting his injured arm. "You bastard…!"

"Come," Tsuna provoked, a smirk spreading on his lips.

Like the mindless brutes they are, they once again head straight to Decimo. He nimbly worked his way out of harm's way. He sent an axe kick to one of the brutes only to be blocked. The man smirked as he grabbed his leg before sending him flying to the nearest tree. Tsuna made contact with the tree with a loud crack, the tree splitting into two parts. "As expected from someone who has an insane body," He muttered, wiping the blood beside his cheek. "You're no pushover."

"Unlike a certain someone…" He retorted with a smug grin as he looked at the boy.

"I'll show all of you who's a pushover." He declared through gritted teeth. He used the flames emitting form his gloves to charge at his opponents with incredible speed. He sent out a powerful roundhouse kick at the brutes which sent them staggering, just like the Varia swordsman's Attaco di Squalo.

Taking advantage of the spare moment he has, Tsuna directed his gaze to his new targets: the gunners who were interfering with their duel. Said gunners fired directly at Tsuna's location but their bullets met nothing as the brunet simple weaved his way through the hail of bullets. Using his gloves, he sent He stopped mid-air; contemplating on what should he do to them. He positioned himself behind the gunners so that he could also get the brutes in one X-Burner.

The gunners did nothing to stop him, completely dumbstruck. "You idiots stop him!"

"Operation X."

"Roger that, boss."

He spread his arms in separate directions as his right burner starts to emit soft Sky flames. "God dammit get him down here come on!" One of the grunts barked at his fellow mafia members. They made it rain with bullets.

The gunfire was deafening, even if he had his headphones on and they were doing little to no job of covering his ears. It left him distracted which gave the brutes their opportunity to drag the brunet to the ground, unsuccessful in firing the X-Burner. It was foolish of him to even think that he could finish them in one go.

"Not so tough now, eh?" one of them asked snarling at him.

"Not so strong, eh? You punch like my mom." Tsuna snapped back with a grin. He clenched both of his fists in preparation for a punch at the man holding him down. He was about to throw his knuckles at him but he was stopped when he felt something.

A sharp pang of pain sent his body flailing. He could feel the cold bullet inside his muscles. He was shot. Meh, it was no big deal. He was shot countless times given his profession; he's already used to it. But this bullet engraved in his skin is somewhat different. The man who was holding him had a gun – it was still smoking – out and it was clear as day to him that he was the one who fired the shot.

"You sick sonnovabitch…" He hissed at the rival mafia members.

His head was starting to get hazy like he was high on drugs or something. His vision was getting a little cloudy. "W-What…?" He couldn't help but ask.

The man who had a bad arm snickered as he got up, still clutching his arm. "You must be feeling the effects of the poison."

"Poison…?"

"Are you deaf or what? That's what I said." The man replied before bringing down his knee on to Tsuna's abdomen. The action made the brunet gasp as he felt his oxygen vanished from his lungs. He coughed wildly as soon as the man removed his knee on his torso.

They all heard a loud explosion far away from their position. By the distance of it, Tsuna could tell that it came from the mansion. His enemies seemed to cheer after the explosion subsided. "Hoho~ Look's like the breach is successful." The man who's likely to be the leader of this team cackled evilly before kicking Tsuna right in his gut. "Your poor friends will be gone in a few minutes…" He paused; grabbing a fistful of the brunet's hair and making him look at him.

"And so will you~" All of the enemy mafia members left not after giving the brunet a little more kicks and punches here and there.

His vision darkening, Tsuna made a futile attempt to stand up and scream for help to no avail. His muscles felt like jelly and he was starting to feel the effects of the poison. He lurched over – the move too quick for his body to comprehend – then coughed up blood.

This is bad, real bad. He could feel his grip on his consciousness fade as the seconds pass by.

"Is… this the end?"

And then, Tsunayoshi Sawada blacked out.

Present…

Tsunayoshi's face flashed inside the prefect and the male illusionist's heads. Kyoya's heart skipped a beat. Something must've happened to his little Tsunayoshi; he was sure of it. He glanced at the portal that was already operational but the tech team insisted on doing some minor checks.

He gritted his teeth. One glance at the master illusionist told him that he also saw Tsunayoshi's face in his mind for a brief second; the scowl on Mukuro's face wasn't that hard to find. He needed to save him. Now!

Both of them were getting antsy, that much Reborn could tell but he doesn't know the reason why. A grim expression replaced his impassive one in a flash. Something wasn't right. Both Kyoya and Mukuro getting impatient proved to be a bad thing. Something happened to his Dame student. And it wasn't good.

Shoichi and Spanner were done checking the portal. "It can be used now. No minor flaws. Repairs were already done." The blond mechanic said, waving his lollipop.

Kyoya's ears perked up at the announcement. A small smirk graced his features. He had everything with him already. His Bracelet of the Clouds Version X circled his wrists securely, Hibird perched on his shoulder; all of his possessions are here, except Tsunayoshi.

At the same time, Mukuro couldn't help but grin. This was it. He was going back to the past to save Tsunayoshi. His grip on his trident tightened. Silently, he approached Nagi and conveyed to her – through telepathy – that he will borrow her Earring of the Mist Vongola Gear. She nodded wordlessly then proceeded to remove the earring from her ear before giving it to Mukuro.

'Be careful, Mukuro-sama.' Chrome said to him via their telepathy link with a small smile.

'I will. Thanks, Nagi. I shall be back soon.' The male illusionist nodded in return, patting the female guardian on her head.

"I have a question though," Shoichi Irie said, raising his hand. The others just looked at him and he took that as a sign to continue. "Who will be going—"

He was unable to finish his question when two figures on opposite directions made a mad dash for the portal. It was none other than Hibari Kyoya and Rokudo Mukuro.

The redhead paled. This doesn't bode well, not at all.

Author's Note:

Heyya, guys! Did'ya missed me? It's been a while, hasn't it? Well I have a tight schedule at my new school. I don't want to fuck up this opportunity given to me by my parents to let me study at my dream university so I have to study hard... at least during tests and shits. Anyway, my prelims are done so I had the chance to write this during my free time. I marathon-ed Assassination Classroom in two days which made me unable to review for my tests and it's so fucking good. I even cried when Korosense had his final roll call T^T Oh the feels! Heck, I'm sorry for being inactive. I'll try to update as much as I can. this is the longest chapter I've ever done in my whole fucking life.

On a side note, things are quite escalating now, aren't they? This story will end in fifteen or less chapters I guess. I have planned this to be a short story anyway. The war has finally started, Kyoya and Mukuro will be in the next chapter I suppose. What happened to Tsuna and Giotto? Can they survive? You'll find out in the next chapter :D

Please don't hesitate to leave a review; it keeps me going :) Oh by the way I have a little extra for you guys down below :D

(This scene was supposed to be deleted but then I decided against it. I just find it too cute for reasons :D Enjoy~)

The redhead paled. This doesn't bode well, not at all.

A soft chuckle brought everyone in the room back to reality. The chuckle came from Reborn. "It seems that you already have your answer." Shoichi just groaned.

"Those bastards…!" Gokudera seethed. He was the right hand man so he should be the one to save their boss from the disaster he was in. "I should be the one to save Juudaime…" He grumbled before stomping his foot on the floor. Honestly, Yamamoto couldn't help but hug the silver-haired bomber beside him. The idiot thought that a sulking Hayato so irresistibly-cute to no end. It made him fall head over heels for the bomber again.

"Haha~ Don't worry Hayato~! It's Hibari and Mukuro we're talking about! Nothing could wrong!" Yamamoto enthusiastically beamed at his lover which made the other facepalm. Seriously, this guy is an absolute idiot.

Everyone in the room paled at Yamamoto's statement. Byakuran released a hearty laugh, "Yamamoto-kun you're really an idiot ne~?" An eyebrow was raised. "Eh? What do you mean, Byakuran?" he asked curiously. He couldn't get what Byakuran was saying at all.

"Baka…" Lambo groaned, "That's what we're worried about. Hibari and Mukuro... Those names just don't fit with each other; it is so wrong in so many levels. It's like adding gasoline to a fire."

"M-Mukuro-sama will be furious if he finds out that Skylark-kun is with him." Chrome commented quietly.

"Well, we could only hope for the best." Ryohei said after releasing a sigh.

The white-haired devil could only laugh at the scene in front of his screen. "Hahaha~! What an interesting family Tsunayoshi-kun has~!" He sang before popping a marshmallow into his mouth.

Reborn frowned despite the amusing scene that plays before his eyes. "Let's just hope Dame-Tsuna is safe."
