Me no own Fairy Tail.

Chapter Five: Roiyaru slayer

Previously: "Heh, don't mention it" Gray said. "Now let's go in and party some more before we head home" He said and the three headed back inside.

Once inside Zeref headed over to Mavis who was talking with Makarov and Gildarts. Natsu and Gray went over to a table where Lucy, Wendy, and Romeo where sitting.

"Great fight like always Natsu-nii" Romeo said loudly, gaining the attention of others that now headed over to them.

"Thanks Romeo, but I really didn't mean to hit her that hard, that's why I used those flames" Natsu said.

"Speaking of those flames, what were they? I've never heard of white flames before" Levy asked.

"They were my Fairy Flames, I make them by mixing my light fairy magic from mom and my dragon-slayer magic, they are strong and burn just as bad as my regular flames but they aren't suppose to burn anybody with a Fairy Tail guild mark." He lit a white flame in his hand and held it out "here, touch the flame" a Levy, Lucy, Romeo, Wendy and Gray reached out and touched the flame, they smiled.

"Its warm and it feels comforting" Lucy said. Natsu stopped the flame and nodded.

"So were the pink flames you used another magic mixture?" Mira asked. Natsu looked around and sighed, he knew they would ask eventually.

"Actually that was just my dragon-slayer magic" Natsu said and scratched the back of his head like he always did when nervous.

"How, we never saw it before" Lissanna asked.

"I actually hid most my power from everyone, but I guess I can tell you guys now" he said, everyone was surprised to know he was hiding things from them for so long. "I'm not an ordinary Fire dragon slayer like I've led you all to believe. I'm actually the King-fire dragon slayer and my foster father, Igneel, was the king fire dragon"

"What's the difference?" Happy asked.

"The difference is power and I can use all types of flames, where as other fire slayers can only use one type of flame." Natsu answered and everyone gasped, they never saw him use any other flames besides his normal crimson before now.

"Can you show us them?" Romeo asked bouncing up and down in his seat, Natsu smiled and nodded then raised his hand as a brilliant gold flame danced in his palm.

"This is the golden flame many refer to 'the flame of rebuke', to humans it's a sign of repenting and accepting ones sins, but to a King-fire dragon and slayer it is the base of all other flames. This is the first flame I had to master to become a King-fire dragon slayer" Natsu said.

"Those were the flames you used to defeat Zero, I thought you borrowed that power from Jellal." Erza said remembering what Natsu told her about the fight.

"Well I did need his flame because I was low on magic, but I used that as an excuse to use a more powerful flame" he said and then made the flame orange.

"This is a normal fire you would see almost anywhere" Natsu said as his flame turned into his usual crimson. "These are the flames I always used, they are very strong and destructive, one of my strongest flames, but they are hard to control, that is why I always caused so much damage to property."

"Then why did you use those instead of a less destructive flame" Makarov asked with anime-tears falling from remembering all the apology letters he had to write and all the money Natsu cost him.

"Because these are my favorite flames, they aren't too powerful, yet they are defiantly not weak. They were also the flames Igneel used most" Natsu said and looked at the crimson flames with a sad smile. He shook his head and made a purple flame and stuck it to the table. "This is just like Macau's fire.

"You could have told me you could do that one!" Macau said.

"I didn't want to show anyone" Natsu said then turned yellow. "I don't really like these because they smell really bad" he said then quickly turned them green and they formed into a hammer that Natsu used to bang on the table, "These do not burn, instead they are solid and are able to be used in many ways."

"That's cool, so it's like my Ice-make magic, but with flames" Gray said taking the hammer from Natsu and swinging it around a little.

"I guess you can think about it like that" Natsu said as he made the flames disappear and then lit a pink flame in his hand, "you have already seen this one, this is my pink flame, it has healing properties, it can heal bruises and other small cuts and injuries, it can ease pain and relax people until they fall asleep, it isn't as good as sky dragon magic though, after all fire is the most destructive type of dragon magic."

"That could have come in handy many times and you never used it!" Lucy yelled.

"I knew we would all live so I never decided to use it" Natsu said as the flames turned a blood red and orange color and the heat in the room sky-rocketed. "This is Hell-fire, the flames from hell itself, they will burn everything it touches until nothing, not even the ashes are left" everyone gasped at the power and heat coming off of those flames. Then the flames melted and turned liquid like lava. Natsu moved his hands and the lava swirled around in the air around Natsu.

"This is one of my most difficult to control flames, mainly because it's like controlling water more than fire, this is Liquid Fire, Igneel use to say that this flame formed one of two ways however nobody was sure which one is correct, the first way was a fire dragon mated with a water dragon and their offspring had a mix of its parents powers, the other story is that a King-fir dragon got hungry and decided to eat the lava from a volcano and accidentally gained the power of lava." He laughed, "With my experience I believe it was the volcano story" and to prove his point he made the lava disappear and had a crimson flame erupt in his hand again only this time it had sparks of lightning throughout it.

"I must really thank Laxus for this new flame, he gave me his lightning power to defeat master Hades, I must say this is one of my favorites, it is very fast and destructive, yet it is somewhat easier to control than my normal crimson flames, so thanks Laxus" Natsu said and grinned at the lightning mage who just nodded.

The flame turned Blue and the lightning vanished, the temperature decreased greatly and a lot of people started shivering. Only Natsu, Gray, Gildarts, Laxus, and Makarov were not shivering at the cold.

"These flames are a mystery, no one knows where they come from, and all we know is that even though it is fire, it does the opposite of what a fire should do. This is Ice-Fire, it is cold not hot, and it freezes and doesn't burn. Igneel said this was his least liked flame, but for me it is one of my favorite flames." He stopped the flames then looked around at everyone. " I suggest everyone stand back for this last flame, I haven't used it around anyone other than mom and dad"

Every one moved away from Natsu. Zeref made them stand on the other side of the guild hall, he knew the only flame he hasn't shown yet was dangerous and he didn't want to risk any ones health by being to close, even from this distance he was sure they would feel a little bit of the effects the flame has. Zeref nodded at Natsu and Natsu lit his hands in a pitch black flame. The guild members saw the flame and instantly knew why they had to move away, they could feel the power radiating from those flames had a dark feeling to them, like they were dead flames that could suck the life out of magic itself. Natsu extinguished the flames and everyone released a breath they didn't know they were holding.

"Natsu what was that, It felt dark, even from here" Lissanna asked.

"Those are my Death-flames, I mix my fathers' death magic and my dragon slayer magic to create them" Natsu answered, "well that is all the flames I can use"

"I knew there was something about you when we first met Salamander, my instincts were telling me you were special, I just never knew that it was the fact that you are a Roiyaru-slayer" Gajeel said as he and the other dragon slayers stepped forward "Guess that makes you our new alpha"

"What does that mean?" Levy asked.

"There is only one King type dragon for each type of element at a time, and those king types can only train one slayer their entire lives, those slayers are called Roiyaru slayers or royal slayers" Wendy answered. "And because he is a Roiyaru slayer, he automatic becomes the alpha in our Ryuzoku"

"And what is a Ryuzoku?" Makarov asked, he was upset he never heard of this in his guild, and it seemed all the dragon slayers were in on it.

"When two or more slayers live in the same area they form a group called a Ryuzoku. In a Ryuzoku, there is an Alpha that is normally the strongest unless a Roiyaru slayer is in the group. The alpha has the groups respect, that's basically it, however if a Ryuzoku in serious danger they will look to the alpha for orders and strength. If the alpha isn't around the group looks to the groups beta slayer, also known as second in command" Natsu explained.

"So Salamander, who is your beta slayer?" Gajeel asked.

"Why that would be you Black Steel" Natsu said and Gajeels' jaw slacked.

"Really?" he asked.

"Yes you, out of all the slayers here you are the most fitting for a beta" Natsu said. "Now can we stop with the questions? I'm kind of getting tired, do you know how tiring it is to travel from Tenrou Island to magnolia in one day? I was hoping to relax and party then sleep." Everyone laughed at that, the rest of the day went by like any other fairy Tail day, guild brawls everywhere, and for the first time in a long time, Natsu was right there in the middle of it all.

Later that night: Grays house

"Here we are, home sweet home" Gray said as he and his guests entered his house. "It's not much but it's cozy" They were in the living room, the wall were blue and had a few pictures of the guild, there was a green couch and tow matching recliner chairs that sat around a nice wooden coffee table that had a blue and green rug underneath. The actual floor was grey carpet. To the right there was a hallway that leads to two rooms and a bathroom. To the left there was a door that leads to the dining room/kitchen.

"Mavis, Zeref your room is down the hall the only door on the left, the bathroom is across the hall." They nodded. "Natsu you will be with me in the room at the end of the hall." Natsu nodded with a smile. "the kitchen is over there, feel free to help yourselves as long as you help with buying food, but do not touch my ice-cream or my root-beer or I will freeze you in a block of ice." He finished and the others sweat-dropped at his threat.

"Thank you Gray, goodnight" Zeref said as he and Mavis headed to their room and closed the door. Natsu yawned and looked at gray.

"Should we head to bed too?" Natsu asked.

"Yeah, come on" He said as they headed to their room and closed the door.

The room was nice, it had a queen size bed that had black cover and had a nightstand on both sides, a dresser and a wardrobe. The floor was a darker grey than the living room. The walls were dark blue and had pictures of Team Natsu. On one of the nightstands was a picture of Natsu with his big toothy grin.

Natsu stripped to his boxers, folding his scarf carefully and placing it on the empty nightstand along with his black dragon necklace.

"so where did you get that necklace?" Gray asked after watching how carefully he treated the necklace.

"Dad gave it to me when I mastered all his black art magic, he said it marks me as the dark prince" Natsu answered.

"That doesn't sound like a really good thing" Gray muttered.

"at first it didn't sound good to me etheir, but then he told me "The dark king and the dark prince are just names given for our dark magic, it can be a good name just as well as it could be a bad name, it all depends on what you make it into" so I accepted the title and one day people are going to say it knowing that the dark prince is good, and hopfully they will know the same thing goes for the dark king too despite his bad past."

Gray came up behind Natsu and wrapped his arms around his waist and kissed the scar on his neck before he rested his chin on Natsus shoulder.

"I already belive the dark prince as well as the dark king are good people" gray said. Natsu turned around to face the ice mage "only a matter of time until the world will know as well" he said as he slowly moved Natsu to the bed. He kissed Natsu deeply as he layed him gently on to the bed then brushed his tounge over Natsus lips asking for entrance witch Natsu gladly allows. Their tounge battled for dominance that gray was sure Natsu was letting him win. After a little longer they separated with a thin string of saliva connecting them.

"Two weeks" Natsu said with a smile "Two weeks and you can become my mate" Gray smiled and kissed Natsu again before laying beside him and pulling the covers over them.

"Goodnight my Dark Prince" he whispered as he wrapped his arm around Natsus waist and closeing his eyes.

"goodnight" Natsu whispered before sleep consumed him.
