Chapter 2

Tsuna stood in front of the guild hall of the guild Fairy Tail. He would head in, but he could hear a large fight going on inside that sounded similar to what he's used to back in his old world. He's going to have to check in Fairy Tail is this world version of Vongola. At least he used to it.

"Are you lost child?" a voice called out making Tsuna turn around and saw a small old man looking at him curiously.

Tsuna shook his head. "No I here to join Fairy Tail. If I'm allowed to that is." For all Tsuna know they might be a age limit or a limit to how many guild members they can have and already at that limit.

"Of course you are." The old man answered. "Follow me and we'll get everything sorted and you a guild mark." Tsuna nodded and followed the old man inside. When they entered they saw most of the guild members were fighting each other. The old man just continue forward and went through like nothing was going on and headed straight for the bar. Tsuna quickly followed being careful to not get hit with anything.

Once they reached the bar the old man jumped on top of the bar. "So what's your name child?" he asked looking at Tsuna.

"Tsuna." Tsuna answered with a smile.

The old man nodded. "I'm Mavarok, the guild master of Fairy Tail."

"Look out!" One of the members shouted getting both of there attention. When Tsuna looked where the voice came from he saw a table flying toward them. Tsuna kept calmed and was about to dodge when Mavarok knocked the table away with an enlarge arm before it shrunk back to normal size. With Tsuna safe he pulled out the guild stamp.

"Where would you like your stamp and what color?" Tsuna thought about it for a moment before taking off his hoodie revealing a red shirt and rolled up his sleeve on his right arm.

"Right shoulder and orange." He didn't really feel comfortable getting a tattoo on his chest or back even if it was more like a stamp and he's not taking off his pants for the guild mark if he wanted on his legs. Mavarok placed the stamp just below Tsuna's right shoulder and a second later a Fairy Tail guild mark appeared, Tsuna didn't feel a thing. With that done Tsuna put his hoodie back on.

Mavarok jumped back onto the bar and faced the guild. "Brats listen up!" he shouted getting the fight to stop and everyone to pay attention to him. "I would like to introduce our newest member Tsuna!" Mavarok yelled while gesturing to Tsuna who felt slightly uncomfortable with everyone staring at him. He has spent the several years living with no human contact, so he's a little out of his comfort zone. It was quiet for a moment before everyone cheered and some kind of party started instantly, weren't they just fighting each other.

Tsuna stood there unsure of what to do before a boy with pink hair ran over to him.

"I'm Natsu and your Tsuna right?" Natsu asked getting a nod from Tsuna. Natsu grinned "Cool our names are reverse of each other."

"You actually have a brain in that skull of your." Another boy said walking over only in his underwear.

"What was that Popsicle?" Natsu asked angrily butting head with the other boy.

"You heard me Flame Brain!" the other boy countered glaring at Natsu.

"Gray your clothes!" A girl with brown hair called out walking over shocking Gray out of the fight and looked down to see most of his clothes are gone. He then left to look for them while Natsu laughed.

"Does that happen often?" Tsuna asked with a sweat drop. Really how do you lose your clothes without noticing.

"Yea!" the girl answered with a sigh. "By the way I'm Cana and if you didn't catch it that was Gray." Tsuna nodded taking note of the names. "So how old are you anyway?" She asked getting Natsu attention.

"I'm eight." Tsuna answered.

"So your our youngest member then. Both me and Gray are twelve and Natsu is ten. There are a few others in our age group but they're on mission right now." Cana explained. "Well if there anything you need help with just ask. Looks like Gray needs help finding his clothes." She said with a sigh and left leaving Tsuna with Natsu.

"Are you strong?" Natsu asked with a grin.

"I don't know." Tsuna replied, he never fought anyone in this new world. He's spared with his mom but he didn't stand a chance against her.

"Do you want to fight and find out?" Natsu asked lighting his fist on fire.

"Maybe some other time." Tsuna answered with a heart melting smile making Natsu blush and nodded.

Time Skip - Time Skip - Time Skip

Two years later since Tsuna joined the guild and he has be enjoying himself while getting stronger. It an chaotic environment he used to and comfortable for him.

"No matter how much time passes the guild never changes." Mavarok commented taking a sip of his beer while thinking of his next move in the chess match he was having with Tsuna. Tsuna currently have him on the defensive but he's about to launch his counter attack.

"Sometime I think they enjoy fighting each other a little to much." Tsuna added with laugh watching the fight.

"There nothing wrong with having a friendly fight with family. Feel free to join them if you want, just know it will count for a loss in our current game." Mavarok then moved a piece on the board and grinned his counter attack starts now.

Tsuna shook his head. "I would but you enjoy our games far to much." Tsuna moved a piece on the board with it. "Checkmate." Tsuna watched as Mavarok stared at the board in total shock before an depressing aura appeared around Mavarok.

"I should feel proud of my child, but I can't help but feel disappointed in myself." Mavarok mumbled sadly to himself making Tsuna giggle, Mavarok always gets like this when he losses at chess. He'll be fine in a minute once he gulps his beer with determination to win the next match.

"Tsunaaaaaaa!" Happy called out flying right into Tsuna chest hugging him. Tsuna returned the hug and started petting Happy's head.

"What's wrong Happy?" Tsuna asked.

"Natsu is being a meany!" Happy cried making Tsuna shake his head. Natsu found an egg three months after he joined the guild and insisted that he help him take care of it. And Tsuna did along with Lisanna and not long after Happy hatched from the egg.

Before Tsuna could ask for more info Natsu came running over to them. "Happy there you are. Oh hey Tsuna." Natsu said with a grin.

"So what's this about you being a meany Natsu?" Tsuna asked teasingly, he already had a guess on what happened since it's usually always involving fish between these two.

"I promise I would buy Happy fish when we got back and he got upset when we passed his favorite fish shop and thought I was going back on my word. I never got a chance to explain I was going to buy the fish here since we get our fish from that shop." Natsu explained pouting slightly.

"Really?" Happy asked turning his head slightly toward Natsu.

"Of course." Natsu answered with a grin making Happy happy. Natsu then looked at Tsuna. "Tsuna do you want to join us for our next job?"

Tsuna was about to decline, but decided against it. "Sure." Tsuna replied.

Natsu face beamed, it's the first time Tsuna has agreed to go on a job with him. "Great let me get Happy his fish while you go pick a job." Natsu said excitedly and left with Happy in tow.

"So you finally decided to say yes to the boy." Mavarok stated back to his normal self.

"I couldn't keep saying no when he keeps asking looking so hopeful." Mavarok grinned, good maybe Tsuna can teach Natsu not to cause to much damage on a job.

"Well aren't you going to go pick a job?" Mavarok asked, Tsuna nodded and got up and head toward the request board.

While scanning over all the request he heard someone walk up to him. "So I heard you agreed to go on a job with Natsu?"

"It is Erza." Tsuna replied glancing to the red head. "Thought it would be a good change of pace."

Erza nodded. "Alright, let me know if he give you any issue on the job and I'll discipline for you. Just don't make him do to much of the work." He expected this since only Master knew how strong he is. He has his reasons why he doesn't want others to know how strong he is but one would be to avoid the spot light, he had enough of that in his past life and none of it was pleasant.

"I won't." Erza gave another nod and walked away. Tsuna turned back to the request board and his eyes fell onto one about taking care of some creatures that been attacking travelers. He grabbed it off the board and walked over to where Natsu and Happy were.

"Did you pick one Tsuna?" Natsu asked as Happy ate his fish happily.

Tsuna held out the job request. "We need to take care of some magical creatures that are attacking travelers."

Natsu grinned "Great we'll leave when Happy finishes his fish."

Time Skip - Time Skip - Time Skip

"Natsu are you alright?" Tsuna asked looking at Natsu. The train just started moving and he just suddenly fell over looking sick.

"He have motion sickness." Happy replied with a sigh. It's a common sight for him now. Tsuna blinked in response and moved to sit next to Natsu and released a small amount of his flames to create a small barrier around them. It's an technique he created from that barrier bubble when he fought Byakuran. He can make them as strong as he wants as long as he supplies the magic power for it, but he can only create them in a limited space around himself and it constantly drains his reserves. The one he made is fairly weak so it's barely taking much from him but should get the job done.

Natsu suddenly sat up looking completely fine shocking Happy. "How?" Natsu asked completely confused, one moment he felt sick and next he was fine. He looked out the window and saw that the train was in motion.

"I created a flame barrier around us that is absorbing the vibration that you feel when the train is in motion. In a way it's tricking you to think that the train isn't in motion." Tsuna explained. He didn't know if it really would work and he's glad it did.

"Barrier? You mean this orange thing?" Natsu asked gesturing to the see through orange bubble they were in.

Tsuna nodded. "Awesome!" Natsu beamed. "What else can you do with your magic?"

Tsuna thought about it for a moment. "You'll find out if it's needed. Just don't tell anyone about what I can do with my magic."

"Why?" Natsu asked confused, he doesn't understand why Tsuna would want to keep his awesome magic a secret to others.

"I have a few reasons why and some are kind of personal, but if I had to list one it would be that I want others to get to know me because they want to and not because I'm strong." So many mafia families tried to be his 'friend' since he was heir to Vongola and proved that he was strong enough not to mess with.

"Alright I promise not to tell anyone and Happy does as well." Natsu said not fully understanding the reason why but it seemed important to Tsuna.

"Aye!" Happy said agreeing with the promise. Tsuna smiled in appreciation at them. The rest of the train ride was a mix of them talking and Natsu looking out the window since it was kind of a new experience for him since he usually suffering from motion sickness.

When the arrived at there stop Tsuna put down the barrier and the three left to meet the client who was the mayor of the town and told them where the creatures were attacking while giving them a map with directions. Once done the head off to complete their mission.

"This should be easy!" Natsu stated as they walked path. "All we have to do is kick butt and mission done."

"It looks like we're here." Tsuna said causing Natsu and Happy to looking around but there wasn't anything around them.

"But there nothing around." Happy said in confusion. Tsuna just gestured to the forest and the two stared at it and after a moment could see eyes staring at them.

Natsu grinned and put his fist together and lighting them on fire. "Alright I'm all fired up!" Like a signal all the creatures hiding charged at them to attack. They were all large wolves and were about forty of them.

"Fire Phoenix's Flame Missiles" Several phoenixes made of flames flew up and then dived where the wolves were charging and each created a small explosion on impact taking out several of the wolves.

Natsu grinned and wanting to be outdone charged forward. "Fire Dragon's Wing Attack" flames spun around Natsu taking out all the wolves near him.

Tsuna lit his hands on fire, "Fire Phoenix's Burning Fist" and gave the nearest wolves a flame infused punch sending it flying back into wolves behind it.

It didn't take long for the two to take out the rest of the wolves without much issue.

"Tsuna what kind of Fire Magic was that?" Natsu asked now that the fight was over. He knew Tsuna could use Fire Magic but he doesn't know what kind it was and he never seen what Tsuna used before.

"Phoenix Slayer Magic." Tsuna answered.

"There are other kind of Slayers beside Dragon Slayers?" Natsu asked in complete shock. "Wait Phoenix's actually exist, so that story wasn't a joke." Natsu paled thinking back to a story his father once told him.

"I'm kind of proof of that." Tsuna replied and sigh, he's going to get a lot of questions now. "Why don't we head back to collect the reward?" The other two just nodded still processing the information.

"Hey Tsuna do you want to go on more job with us?" Natsu asked a few minutes later.

Tsuna thought about it for a moment, "Sure. Not every job, but I won't mind doing one with you guys every now and then." Tsuna usually donates some of the money he gets from his jobs to the guild to help pay for some of the bill the guild has to deal with. There kind of a law that all damages done by a guild has to be payed back by the guild. And that's done from taking money from the job reward and billing the guild for the cost. So going solo on jobs let him donate more. And lets not forget Natsu is one of the guild main offenders when it comes to that bill.

Natsu beamed at Tsuna response. "Sweet lets go on another when we get back!"

Tsuna sighed but smiled. "Alright I can do another."

So people have been commenting about the whole Natsu x Tsuna I was thinking about doing and probably won't be doing that. It was just a thought since the story has them as very close friends and would have been easy to change it to them as a pairing. So what I'm most likely going to be doing is just add in parts where it could be implied and if you don't like it then too bad.

Also to answer some questions. First, Tsuna only has regeneration when he uses Phoenix Drive which is something he doesn't use often due to several reasons that will be explained much later in the story.

Second, the reason I choose for just Tsuna to be the only one from the KHR universe is because most stories I see has mostly everyone from the KHR from Acrobaleno and his Guardians joining him as well and wanted to do something different.

I would like to point out that Tsuna isn't going to be apart of every Arc that happens normally in the Fairy Tail story. Tower of Heaven is one since I wanted Tsuna to be there for the recruitment of Gajeel and Oracion Seis since Tsuna is going to have his own mission going on while the Allied Forces are fighting them.
