DICLAMIER: I DO NOT OWN KATEKYO HITMAN REBORN.

Chapter 1

Small feet ran down the alley as he breathed heavily. His hand tightly grasping the taller boy in front of him as another boy walked closely behind him. None of them really knew where they were or what was happening but they knew something was wrong.

Tsuna tripped but was helped up with steadying himself by the person standing behind him as the three boys continued running. Tsuna dropped from the stress forced upon his small body. His breathing became more uneven than before. "My body can't handle this… I'm trying but I just can't take it in this body."

Mukuro who stood behind him glared backwards to see if anything was behind them. "That's obvious. You're younger than us, not to mention you had to seriously train your body to handle the flames you carry."

Tsuna collapsed, still breathing heavily as he saw the person in front of him stoop down. "Then we'll take turns carrying you until we know for sure we can stop safely. Get on my back."

Tsuna did as he was told and Hibari carried him while running with Mukuro beside him. The two older boys sprinted as fast as they could with one carrying the youngest boy. Mukuro could still sense the people following behind them. "There still coming," he warned.

Hibari cussed as he stopped. "Change." Quickly, Hibari slipped a tired Tsuna onto Mukuro's back.

Mukuro took Tsuna and they started running again. Finding an exit, they turned, only to see more people on the other side. Both boys swore and Hibari grabbed his tonfas.

Hibari launched a first attack taking the men by surprise. He cleared the path with ease. Just when Mukuro was about to make a break for it, someone grabbed Tsuna's shoulder from behind.

Mukuro materialized his trident and stabbed the assailant in the shoulder, causing him to let go of the smaller child. Mukuro set Tsuna down. "Try not to get in the way."

Tsuna went to the middle of the tussle and used his ring the release Natsu who started attacking the men who came to close to Tsuna. Somewhere in the middle of the fight, someone grabbed Tsuna. A gun was aimed at the small sky's head at point blank. It effectively got Mukuro and Hibari's attention. They saw Tsuna close his eyes and Mukuro raised his voice in panic. "Tsunayoshi stop! Your body can't handle it…"

Not listening, Tsuna released a large amount of flames burning the men around him. He fell to the ground and briefly glanced at the two people towering over to his dazed state. "Guys I'm sorry but I'm so ti…red…"

Tsuna fought to keep his eyes open but his body was failing him. Hibari and Mukuro formed a protective barrier around him. "It's fine. You can go to sleep now. You'll be safe. We will be okay."

As soon as Tsuna heard the reassuring words, his eyelids fluttered shut.

Mukuro looked at Hibari, crestfallen with despair. "What do we do? Our bodies can't handle this for that much longer either."

Hibari looked at him, "We have to. The stress is the worst on him. At least our flames aren't destroying us from the inside out. His flames are too strong for his body and if he uses them too much, it could do permanent damage."

Mukuro sighed, the tension not leaving his body. "I know. If it wasn't for how well he can control his flames, they would have already destroyed him. What should we do now?"

Hibari picked Tsuna up in his arms and walked. "We have to figure out where we are and a place to stay so he can rest. We also need to figure out how to get back home."

They continued to run since that was all they could do. None of them knew what was happening to them. They had seen a light in the middle of a routine fight and ended up like this when they woke up.

Immediately Mukuro and Hibari started fighting again when they awoke not really caring about the change but they stopped when the person who was also there had first collapsed.

Usually Tsuna would stop their fights abruptly with practiced ease but when he woke up he collapsed right away causing them to stop. They were very close now although they often fought they were all in their thirties in their normal bodies. They lived together in the Vongola mansion. That was when they started to get along a lot better. However despite the closeness they shared, they still fought over one and only one thing - Tsuna.

Both the illusionist and skylark noticed it quickly after Tsuna had graduated from high school. Tsuna had started taking life and everything around him more seriously. They found that aspect of him rather cute. In other words Tsuna was perfect for strong men like themselves.

To others, Tsuna was a very strong and scary person but to those who he held close, Tsuna still would show his more natural clumsy side although he was definitely nowhere near as clumsy as he was.

Tsuna had also become a lot calmer with age. He had matured a lot because of the battles and situations he was forced to participate. Being the way he was always made Mukuro and Hibari feel like Tsuna really need them, which at some point, for all three of them had morphed in to a messed up three-way relationship. It amused those around them, especially the other guardians.

The two guardians found an abandoned house and Mukuro found some blankets. They quickly made the place comfortable and let Tsuna rest on the bed as they watched over him.

Tsuna was having a fever and neither of them had the vaguest clue as to what to do. Even if they did, neither one of them was sky flame users nor did they have any idea how to absorb another person's flames. Also, their bodies as they were wouldn't be able to take it.

After finding Tsuna another blanket since he looked cold, the two children decided on taking turns to keep a look out for the night. The shift was five hours so the other had time to rest. Mukuro opted to go for the first shift.

The next morning when Mukuro had woken up Hibari had already gone out to find out where they were so they could return to Italy and get someone to help them but when he came back, Hibari was expressionless. Mukuro cracked the silence with an anxious voice. "Where are we?"

Hibari looked at him with impassively. "In Italy."

Mukuro looked slightly confused. Clearly there was something bothering the skylark and Mukuro was one of the few people who could read that poker face. "Then what's wrong?"

Hibari let out a frustrated sigh and said, "We're in the past."

Mukuro just laughed, "Kufufufu... Of course we are. So what's the real problem?"

Hibari glared at him with eyes that screamed he was calling Mukuro an idiot. "Stupid herbivore…"

Suddenly Tsuna woke up and bolted up. He stared at the wall and then stood up heading towards the door. Mukuro went to stop him but Tsuna just moved slightly, avoiding his hand to continue walking out the door. "Tsunayoshi, where are you going?"

Tsuna glanced at him for a second, "Where my instincts are telling me to go, my Vongola Hyper Intuition is acting up."

The two children followed behind their boss. Tsuna walked down the roads as if he knew exactly where he was going although he really had no idea as he followed the small feeling at the back of his head. "Herbivore, where are we going?"

Tsuna shook his head. "Don't know where, just that it's this way."

Tsuna just kept walking and then suddenly he stopped at a corner and leaned against the wall obviously waiting for something to happen. "Something's going to happen here soon."

Tsuna just watched with his eyes locked straight on a set of doors across from the alleyway they were sitting in. He knew where but not what was going to happen.

Mukuro glanced at Tsuna's eyes and saw how calm he was and sat down. He knew from experience that when Tsuna makes the face he was making, Mukuro just had to wait and trust him because his instincts were never wrong.

He materialized his staff, setting the tip against the wall above his head. Tsuna saw a blond woman walk out and instantly he was gone when he saw the people coming out of the shadows to attack her.

Tsuna jumped between the women and the gun. He used his flame to destroy the man's gun. He no longer needed a weapon and could control his flames using his bare hands even if it required a great deal of concentration.

Mukuro and Hibari were quick to act behind Tsuna since they knew it would happen. If Tsuna was ready to attack, so were they.

They moved quickly and took the other men out. Tsuna smiled as he collapsed from the small amount of flame he had used. The women looked at him full of concern as he smiled in relief and whispered as Mukuro picked him up, "Elena's okay."

She was surprised as she looked at a very fancy envelop in her hand. Hibari looked at it and saw the Vongola seal on it. Understanding clicked. He looked at Mukuro. "Let's go herbivore, before they arrive, he's already worn out. We don't need more trouble to deal with."

Mukuro was about to turn but was attacked. Hibari stopped the man's cane from hitting both Tsuna and Mukuro in time. Mukuro glared at him and growled. "Daemon Spade..."

Elena was between the kids and her lover as fast as she could manage. "How dare you attack them Daemon! They are just kids and they saved me."

Daemon stopped and quickly looked them over and then looked back at Elena. "Do you have the envelope?"

Elena nodded as she showed him. "Yeah, it's here."

Daemon looked at his wrist watch. "Then we need to leave."

Mukuro turned to leave with Hibari beside him but Elena pulled Tsuna from his arms and cradled the small brunet in her own. "Okay, we need to return to the house anyways to help this child. He's sick."

Mukuro and Hibari were about to protest but stopped when they remembered how ferocious women could be. Thinking back to the multiple times that gentle little Kyoko had gotten pissed off at them and almost ripped their heads off sent shivers down their spines. They agreed.

The next thing they knew, they were in a horse drawn cart with Elena and Daemon. The two children could guess rather easily where they were going.

When the cart stopped their suspicions were spot on. They had seen the place more than they could remember in the future. They knew it like the back of their palms for they lived in it. Every hallway brought back memories from the time Tsuna burnt an entire column using X burner to the time they had food poisoning from a party the poison scorpion threw. Those were the good old days.

They jumped from the cart simultaneously and followed closely behind Elena in case they needed to forcefully take Tsuna from her arms and run. Once in the house they noticed people that they recognized from the trials they had to take. They watched G and Giotto walking down the stairs. Giotto looked down at Daemon from the staircase. "Daemon what's wrong?"

Elena looked up answering for him. "I was attacked but this child saved me with his friends. Though after he saved me he collapsed. I think he's sick. Can you help him Giotto?"

Mukuro and Hibari looked at Giotto, probably the only person who could really help Tsuna as a fellow sky flame user, they could do nothing. They were not even able to relieve Tsuna's pain like Ryohei. Now, the man standing in front of them was their only hope of removing the extra flames that were putting stress on Tsuna's fragile body.

Swallowing their pride, they stepped forward to explain the situation. Mukuro told Giotto in his mother tongue. "His body can't handle his sky flames."

Giotto glared at the child with heterochromic eyes and reached out for the small child in Elena's arms. He placed his hand on Tsuna's forehead. A larger than normal amount of flames were released. Instantly Tsuna woke up and noticed the change. He smiled cutely and said in Italian. "That feels so much better!"

Giotto smiled, "That's good to hear. What's your name?"

Tsuna looked up at the Vongola Primo. "Sawada Tsunayoshi."

Suddenly Ugetsu walked in from the adjunct room. "So he's Japanese but can speak perfect Italian at such a young age… that's rare."

Giotto looked over. "He was probably raised here."

Ugetsu nodded and laughed. "Probably!"

Tsuna smiled as he jumped down from Elena's arms and went to Mukuro and Hibari who pushed him behind them. They were on full possessive mode with him, not trusting the people around them. Tsuna just beamed brightly behind them as he watched Giotto.

The two locked eyes and instantly Giotto's hyper intuition flared. He glanced at Daemon. Daemon got the hint and tried to trap the two children who were snarling like dogs in an Illusion so they could talk to the calmer one but he failed as Mukuro's earring began to release mist flames and he materialized his trident to stop it.

Daemon was surprised. Did that mean the kid was a better illusionist then himself? Mukuro just laughed at the priceless expression of the narcissistic mist guardian. "Kufufufu."

Mukuro was about to use more of his illusions and when he was about to change to the mist weapon gear, Tsuna took his staff and whispered in to his ear. Mukuro stopped and Tsuna held his staff between his arms and looked at Giotto again. He spoke in Japanese instead of Italian this time. "We'll just be leaving then. I thank you Giotto-san for helping me with my flame issues, goodbye."

Giotto was instantly between Hibari and Mukuro holding Tsuna's arm. "I would like to talk to you alone first. Can we have a conversation in my office before you leave?"

Tsuna nodded handing Mukuro his weapon back. He said while laughing at the end, "I'll be right back, so don't you two wreak the place while I'm gone okay?"

Tsuna walked behind Giotto up the stairs and straight to the man's office. They entered and Tsuna sat down. "Who are you really? My intuition keeps telling me you're not a child and so does the way you act. You're too calm."

Tsuna smiled. "You wouldn't believe me even if I told you."

Giotto mirrored the smile. "I'm used to some pretty weird things."

Tsuna chuckled. "Yeah, we both are. Fine, I'll tell you but it's probably easier for you to understand if I just showed you so can you get my friends to come up here."

Giotto went out of the room and told G, who was standing outside, to tell the other kids Tsuna had asked for them. G did as told and in a few minutes, Mukuro and Hibari were walking into the room arguing about something. Tsuna sighed as he looked at them. "You guys are hopeless. The second I leave the room, you start to bicker."

Hibari made a clearly unpleased noise as Mukuro looked up. "He started it." They pointed at each other simultaneously.

Tsuna pinched the bridge of his nose. "Mukuro, you're not ten so stop acting like it."

Mukuro laughed creepily. "What did you want us for Tsunayoshi?"

Tsuna spoke. "I need you to use your illusions on our bodies to make us look like how we normally do."

Mukuro ku-fu-fued. "That's not very hard, but it won't last very long. This body has got a limited amount of time that I can use for stronger illusions."

Tsuna nodded his head. "It doesn't need to be for very long, just long enough so he'll understand."

Mukuro took a deep breath and brought the mist staff to his hand. Purple smoke enveloped the three of them.

As the purple smoke dispersed, three adults were revealed. Tsuna sat with his legs crossed and the two took their places behind him.

Tsuna was in his orange dress shirt and a black jacket with black pants. Mukuro was a in an indigo dress shirt with long sleeves, black pants and a black jacket with indigo gloves. Hibari was in a black shirt with a violet jacket and black dress pants with a small amount of purple detail.

Tsuna smiled at Giotto. "I'm your great-great-great-grandson. Also I'm Vongola Decimo, these two are my mist and cloud guardians and somehow we were turned into children and sent back in time."

Giotto was surprised. He could handle a lot but this was definitely very surprising. He was not expecting something like that. "So you are from the future then?"

Tsuna nodded. "Yes we are."

Giotto looked at them and noticed how the illusion was breaking apart slowly. He could not imagine how strong Tsuna's mist guardian was if he could handle Daemon's illusion even in his current state.

Giotto saw Tsuna wince as he leaned forward in pain. Both guardians rushed forward. Mukuro frowned as his hand rubbed soothing circles on Tsuna's back in concern. "It's happening again already?"

He dropped the illusion as Tsuna turned little again, buckled over in pain as his flames quickly became too much for him to handle. "My flames are way too much for this body… I have a hard time with them normally but in this body it's too much to handle. At this rate the stress on my body could end up killing me if we don't do something about it soon."

The guardians bit their lips worried as Giotto stood up and went around. Giotto kneeled in front of Tsuna and took his hands, "Now slowly release some of you flames."

Tsuna did as told and slowly began transferring his flames to Giotto, Giotto winced at first causing Tsuna to stop, "It's fine, it's just not something I'm used to doing since there aren't many with sky flames around. I'll be fine so keep releasing your flames. This should be the easier way to do it for you body."

It took quite a while but Tsuna released all of his excess flames, Giotto just changed the flames in to his own, "I didn't remove enough earlier, but now you should be okay for a while this time."

Tsuna looked at his hands and closed his eyes for a second, "It will only last until tomorrow afternoon at the most."

Giotto stared at him, "Are you sure?"

Tsuna nodded. "Yes. I produce flames at a higher rate than most because I've absorbed so many other peoples' flames during fights. Over the years it increased the amount of flames my body makes on its own. I didn't notice it until it was too late to change the effects it had on my body so instead, I learned complete and utter flame control so my body could actually handle it. The extra flames my body creates now comes in handy during fights, so it's not all bad."

Giotto nodded. "Stay here until you find a way to return home. I will arrange it so we can transfer flames daily. My body isn't at its maximum limit so I can handle absorbing at least this amount of your flames daily if not a little more."

Tsuna muttered his thanks as he breathed out a sigh of relief and hugged both his guardians draping an arm over each of their necks. "Let's try and fix our bodies so we can lessen the burden for Giotto."

The two guardians nodded at him and then hugged him back, happy that he would be fine for now.

In reality, they had no clue what was really happening but they trusted him with all their hearts and more.

Giotto observed how closely bonded Tsuna was with his two guardians and smiled. He would be a fine boss and knowing the future of Vongola was in good hands made him relieved.
