Katekyo Hitman Reborn

What if only Tsuna and his Guardians were sent to fight the war against Byakuran in the future, what if 2 weeks had passed in the past and what if no one else got their memories of the future?

Warning: AU, intense bloodlust, possessive behavior and teetering on the edge of insanity, close to Yaoi behavior

Chapter 4

"Are you sure you want to do this Tsunayoshi?" Timoteo asked his heir carefully as he looked around the barren area that the large group was gathered a week or so after they were finally released from the hospital and tearful reunions were had.

"It's necessary Nono otherwise Xanxus will never accept the powers we got from the future." Tsuna said knowingly and turned to his Guardians who were all bickering or stretching in their own way in front of the group.

"Ok everyone hold off on Cambio Forma for now." Tsuna ordered and they all nodded.

"Uri!" Gokudera called out and a cute storm cat appeared on Gokudera's shoulder yawning a bit. His Vongola ring glowed next; his left arm covered in Storm flames revealing a skull launcher with storm flames flaring from the base. Numerous boxes were slung across his hips and giant bone loops hovered over his head.

"Sistema C.A.I" Gokudera smirked

"Kojirou!" Takeshi smiled as a Rain flamed swallow appeared, circling Takeshi's head as Shigure Kintoki glowed with his flames.

"Kangaryuu!" Ryohei's rings glowed and a Sun kangaroo appeared decked out in boxing gear and rocket launchers on his back while Ryohei gained white Vongola boxing gloves as he threw a few punches into the air.

"Gyuudon!" Lambo cried and a massive black armoured bull appeared, Lambo nestled onto the crown and hugged the bull happily while said bull huffed out a puff of air.

"Roll." Kyoya's tonfa's flared with his flames and cute little purple flame hedgehog appeared on his shoulder yawning cutely before he spring boarded off of his master's shoulder and suddenly was now encased in a giant spiked purple ball.

"Mukurowl." Chrome gripped her trident and silver owl with Mukuro's red eye appeared and perched on her shoulder eyeing the gathered group (excluding Tsuna and the other Guardians) with annoyance.

"Natsu." Tsuna smiled as he slipped into hyper mode easily, without the need of pills. His gloves appeared the blue gem glowing brightly as Natsu appeared the Sky flame mane flaring as he 'gao'ed cutely and nuzzled Tsuna's cheek.

"What are those?" Basil asked curiously.

"Vongola box animals, basically extensions of ourselves created 9 years in the future. They are our partners and have helped us through a lot of battles." Gokudera explained, as he understood the boxes better as it took him quite a lot of time to understand his own box weapon system.

"Can we fight now?" Ryohei asked excitedly his boxing gloves now covered in his sun flames.

"Alright, alright. Everyone pair off." Tsuna nodded his consent and launched himself into the sky to dodge a barrage of Rolls as Kyoya attacked.

"Come on Hayato lets have some fun!" Takeshi laughed as he leapt towards Hayato who evaded the slash of the sword by skidding to the side on a hovering disk of Storm flames.

"Baseball idiot!" Hayato growled and let his skull rings flare up with every (other than Sky) flame and he unlocked the correct box as Uri launched herself at Kojirou.

"Let us spar Lambo! Chrome! Mukuro!" Ryohei beamed at the last two. Chrome nodded and stabbed the end of her trident into the ground and the ground erupted into pillars of flames and roots lashed up from the cracks grabbing at the Lightning and Sun.

The gathered group stared at the Decimo generation as they sparred with each other, powerful blasts coming from each battle every so often.

"How are they this powerful?" Bianchi asked in awe as she watched her brother shot a burst of Storm flames laced with what looked like Lightning flames towards Yamamoto who was engulfed in his own flames and used them to dodge the attack.

"Intense training and many battles." Reborn said seeing the way they each moved showing they each had experienced trainers who knew them very well.

"X-Burner!" Tsuna shouted, launching his hard flames towards the wall of Rolls, breaking through them he sped towards Kyoya and Kyoya blocked the oncoming punch with a tonfa and grinned bloodthirstily at the brunet who smiled back.

"That attack was amazing!" Basil breathed out seeing how Tsuna had fired flames from one hand behind him to intensify his flames in his other hand.

"Shigure Soen Ryu eleventh offensive form, Beccata di Rondine!" Takeshi launched a familiar attack at Hayato who had to use his bone loops to protect himself and Squalo stared slack jawed at the sword-teen.

"Damn you really did perfect his attack." Hayato grumbled.

"Of course I did, you think Squalo would have let me leaving that forest without making sure I was ready to fight? He's a slave driver!" Takeshi laughed fondly thinking back to his time with future Squalo.

"How were we suppose to know what happened? Squalo just appeared giving Dino a giant tuna and beat the shit out of you before taking off for a week." Hayato snapped back, betraying how worried he had actually been when that happened.

"Yeah it was interesting living out in the forest with him, but he's really amazing." Takeshi said reverence in his voice.

"VOI what the fuck?" Squalo had enough of this and went to jump in when Xanxus whacked him over the head with his X-Gun and growled as he kept his red eyes on Tsuna who was now circling around Kyoya leaving a powerful trail of Sky flames behind him.

"Want to take this up a level?" Takeshi asked curiously.

"Fucking finally." Hayato smirked.

"Kojirou, Jirou Cambio Forma!"

"Uri Cambio Forma!"

"Asari Ugetsu's Four Irregular swords!" Takeshi was joined by a Rain flame husky who had small sheaths on his back while the swallow merged with Shigure Kintoki giving the sword a winged hilt that glowed with Rain flames and three smaller sword hilts creating the blades out of flames were gripped in Takeshi's left hand.

"G's Archery!" Gokudera was holding a long white bone bow, red storm flames on the string and Gokudera drew the string back and an arrow formed out of Storm flames appeared there.

"Holy shit, are those what I think they are?" Colonello asked staring at the familiar weapons in shock.

"The first generation's weapons." Timoteo confirmed in awe.

"Gyuudon! Cambio Forma! Lampo Shield!" Lambo went next and soon was holding a fancy shield that had arches of lightning flames coming off of it.

"Roll, Cambio Forma. Alaude's handcuffs." Kyoya twirled black handcuffs from his fingers as they multiplied.

"Natsu,Cambio Forma Mantello di Vongola Primo." Tsuna was covered in Primo's black mantle, flowing out around him from his place high in the sky.

"Now it's a fight." Hayato grinned as he launched a storm arrow at Takeshi, who used the three smaller sword hilts to allow him to dodge the attack.

"Impatience aren't we?" Takeshi laughed as he flew into the air, drawing his sword back as he dropped down towards Hayato.

"Omnivore." Kyoya growled as Tsuna laughed as he flew around every handcuff that came his way.

"Getting annoyed already Kyoya?" Tsuna teased getting a growl from the Cloud.

"Why is my son purposely annoying his violent Cloud?" Iemitsu rubbed his forehead.

"It's the best way to get Kyoya to react." Dino said eyes tracking their movements intently.

"That brat is toying with him." Reborn shook his head in disbelief, never expecting to see Tsuna toying with Hibari of all people.

"And he's having fun doing it." Fon concluded, his own lips twitching upwards at the thought.

"That can't be all you've got baseball idiot!" Hayato laughed as one of his arrows forced Takeshi back closer to the group of watchers. Takeshi heaved himself back onto his feet with a grin, danger rolling off his body in waves.

"Oh I'm just getting warmed up Hayato." Takeshi gave a grin full of teeth and he launched himself towards the Storm, said Storm yelped and threw himself to the left to avoid being hit by his next swing of his sword.

"That's more like it!" Hayato grinned in the same way that matched Takeshi.

Ryohei was ducking around arches of Lambo's Lightning flames while Chrome was now sparring with Mukurowl that had shifted into the shape of Mukuro, the older Mist was teaching Chrome how to execute a difficult move using their tridents and flames.

"They are amazing." Basil said star struck.

"Something is different about them…" Colonello muttered to Reborn as he crossed his little arms as he watched the fight.

"We need to stop this fight." Fon commented.

"What? Why? It's just getting good!" Squalo questioned having heard the Acrobaleno's comments.

"Look closely." Reborn jerked his head at the fighting Decimo generation. Each of their moves were getting more and more violent, coming closer and closer to actually causing harm to their fellow guardians and even Xanxus had to blink a few times as waves of bloodlust were starting to roll off the fighters.

"They are loosing them selves in the fight, in the bloodlust." Reborn continued on.

"Tsunayoshi! Stop this before one of you gets seriously injured!" Iemitsu shouted and Tsuna dodged an attack by Kyoya to look at his 'father' with dead looking orange eyes.

"Where's the fun in that?" Tsuna tilted his head to the side, a disturbing smile spreading across his face. Iemitsu blanched at the sight and his son's words.

"Shit." Reborn muttered and tensed up his small body before he leapt into the fray, landing on Tsuna's head and whacked him with the Leon-Mallet, hard.

"OW! Reborn what the hell?" Tsuna dropped out of his HDW, eyes turning back to their usual brown. Natsu appearing back in his lion cub form and nudged at Tsuna's legs playfully.

"Stop your Guardians' fights Dame-Tsuna before someone gets hurt." Reborn ordered, grabbing onto Tsuna's hair tightly.

"Ouch, okay I will sheesh." Tsuna grumbled as stinging pain emitted from where Reborn was pulling his hair.

"GUYS! Fights are over, tone it down!" Tsuna cupped his hands over his mouth as he called out to his Guardians who all instantly stopped and let their weapons turn back into their box animal form, Kyoya actually pouted a little before leaping up onto a flat topped boulder and he settled down there for a nap, Hibird resting on his head and Roll on his chest.

"That was an extremely good work out!" Ryohei grinned as he carried Lambo over in his arms, Gyuudon andKangaryuu following behind them while Takeshi had draped his arm over Hayato's shoulder, Kojirou on Takeshi's head, Jirou walking by his side and Uri was clinging to Hayato's had. The two were bickering as per usual and Chrome joined the boys with Mukurowl on her shoulder, Mukuro watching from his eyes.

"Why did you want us to stop Reborn?" Tsuna asked curiously as the spectating group started towards them.

"You couldn't tell?" Reborn asked raising an eyebrow.

"Nope, we were just sparring." Takeshi laughed while the others agreed.

"That was just sparring?" Colonello asked incredulously.

"You didn't feel any of your bloodlust getting higher?" Dino asked worried for his little brother and his student who was napping currently.

"You think that was high?" Hayato raised both his eyebrows before he started to laugh.

"It was on par with the Varia trashes." Xanxus admitted angrily.

"…Oops?" Tsuna offered up, holding his hands up in surrender.

"Oops?" Xanxus growled, hands twitching like they were going towards his X-guns.

"An explanation would be nice." Timoteo asked gently.

"Not that much to explain, we felt more bloodlust from Lal when she first met/attacked us when we appeared in the future." Hayato shrugged, stuffing his hands in his pockets noticing how Colonello flinched with his eyes wide at the mention of her name.

"Every battle and spar after that involved bloodlust in some way and ours just built up to match those who were surrounding us I guess? The bloodlust coming off of future Kyoya, even future Onii-San were insane but nothing compared to Byakuran, if we hadn't managed to raise our own bloodlust that alone would have crushed us before we even fought him." Tsuna explained in better detail than Hayato was willing to do.

"Why didn't you stop fighting when Iemitsu told you to?" Timoteo asked curiously.

"I don't take orders from him." Tsuna said simply, doe eyes going dead again.

"If we're done here, I told Kaa-San that we were going to be coming home for dinner, all of us. So we better be off." Tsuna gesturing to all his guardians including Kyoya who was now jumping off the boulder to linger at the outskirts of the group forever the wandering cloud.

"One last question." Iemitsu stepped forward noticing how Hayato and Takeshi all tensed and moved closer to Tsuna and Natsu started to growl at the blond man.

"Make it quick." Takeshi answered for his Sky.

"…Why do you seem to hate me so much?" Iemitsu asked.

"Juudaime doesn't have to answer to you." Hayato spat out, Uri bristling on his head.

"It's fine Hayato." Tsuna grabbed Hayato's hand and instantly Hayato calmed down as their flames harmonized. Reborn noticed this and smirked, his dame student had learned a lot when he was gone and reborn couldn't wait to train him further to see what else he learned.

"I hate you because you not only are breaking Kaa-San's heart in this time period but because in the future she died because of you, because you put Famiglia before family. She was tortured because she was married to the leader of the CEDEF and mother of Vongola Decimo, she didn't know anything. She died in my future Storm's arms, choking on her own blood begging to see her son one last time, not knowing that her son was already dead and buried. She died because of you, because of me, because of Vongola." Tsuna's voice was flat and emotionless as Iemitsu paled drastically while anger and sadness flared up in those who knew Nana, even those who didn't.

"I will save the Vongola, but if it's too far gone I will make good on my promise to Primo. I will burn it to the ground." Tsuna's eyes turned orange and his voice deepened more like a lion's roar. Timoteo eyes widened at his heir's words, Dino couldn't help the smile that was on his lips and Xanxus felt his lips twitch up, the brat had a backbone after all, this was going to be fun.

"Tsuna." Takeshi hugged Tsuna and the two were engulfed in Takeshi's Rain flames and soon Tsuna was slumping against Takeshi's chest with a happy purr.

"You're a real bastard." Hayato snarled at Iemitsu who was stumbling backwards, hand at his mouth.

"Come on, let's go see Mama, yeah?" Takeshi asked his Sky who nodded hazily and let his Rain heave him up into his arms to be carried. Natsu trotted over to Chrome and pawed at her boots, she smiled softly and allowed Natsu to leap up into her arms and curl up there.

Hayato, Ryohei, Lambo and Chrome followed Takeshi who was walking away from the barren field with their Sky. Kyoya glowered at Iemitsu before following his pack; Mukurowl flapped his wings in front of the CEDEF leader.

"If you hurt my Sky again I will send you into the deepest level of hell after I torture you." Mukuro said, voice dark before he soared away to join the others.

"Way to mess up Baka-Iemitsu." Reborn shook his head in disbelief before he followed his student (future boss perhaps) intent on observing more of their behavior and to help his Dame student in recovering from this in anyway he could. Fon and Colonello followed on Dino's shoulders as the Bronco wanted to be there for his little brother and if he was serious about burning the Vongola to the ground then he would help in anyway he could, he believed in Tsuna and his family.

"Iemitsu, I believe it's time you finally pick. Famiglia, or family." Timoteo turned to look at his CEDEF leader with a grave look on his face. "You have until the end of the week and you better choose correctly or I'm afraid you will loose more than you realize."

Iemitsu nodded mutely while Timoteo gently led Basil away from his master, the Rain flame user going without complaint.

"VOI, what are you thinking boss?" Squalo asked Xanxus as the two also parted.

"I think we should move to Namimori, things are going to be a lot more fun around here with the brats like that now." Xanxus laughed.

"Get Mammon working on making us rings and boxes, I will not allow those trashes to stay ahead of us." Xanxus ordered.

"VOI like hell they will boss." Squalo agreed giving a sharp grin, already preparing for the next spar he was going to have with that Katana brat.
