Sky Devil Slayer

Disclaimer: I do not own Naruto or Fairy Tail

Chapter 1

Makarov frowned as he looked at the walls and the floor of the base of a dark mages, they were covered in blood. He looked to a few dark mages who were tied up with their magic sealed as a few other light mages and Rune Knights.

Makarov walked over to a desk that had a few torn pages on it. The dark mages were trying to cover something up. The knights took the dark mages out of the base as a few of the mages decided to assist them.

The third guild master of the strongest guild in Fiore, Fairy Tail, was reading through the torn pages piecing them together. What he read shocked him. The third guild master than took of down deeper into the dark mage base.

If the torn pages of the journal were telling a truth, there was a child down there. A child used for killing due to the magic he had, slayer magic. He didn't have Dragon Slayer Magic or God Slayer Magic, he had Devil Slayer Magic.

Magic used to slay demons or demons of the dark mage Zeref. These mages had captured a child who knew this magic and used him to kill their enemies. It made him sick.

Makarov stopped at a cell and using his giant magic to increase the size of his fist pulled the door of its hinges. Makarov entered and saw a young child with messy blonde hair and blue eyes stare emotionless up at him.

His clothes were stained with dried blood and they looked a little torn around his arms. Makarov looked at the child in sadness, to be used like this. He wondered if the child had a family or was he a slave that the dark mages captured used after witnessing his magic.

"Hello young one" Makarov said. "What is your name?"

"…" The child stared up at Makarov until he opened his mouth. "Naruto"

"Maelstrom huh" Makarov said as he walked towards the child carefully. When Makarov started to raise his hand to cut the shackles of the boy he noticed the boy flinch a little. They had beaten this child! It made Makarov's blood boil.

"I'm not going to hurt you" Makarov said as the child stared up at the wizard saint. "You won't be in this place anymore" Makarov said as he broke the shackles.

Makarov looked into the child's eyes, they were devoid of life and needed, no required a purpose. He was used to kill and only kill, he then had an idea for the child to experience a normal life, as a guild mage.

"What about my purpose?" He asked the old man.

"How about you join Fairy Tail"

"Fairy Tail, what's that?"

Makarov smiled. "It is a guild of mages, not like these dark mages you were with. We are a family and you can be a part of it"

"A family…" He said as his thoughts trailed off wondering what a family was like.

"However there is one rule for you to follow" The old man said getting the blonde to look at him.

"A rule, like my killing someone you want dead?"

Makarov's eyes widened and quickly shook his head. "No, no nothing like" He said. "Did those dark mages make you do that?"

Naruto nodded. "If I killed for them they stopped with the beatings… for a while"

Makarov looked angry at what he heard before he turned back to Naruto with a smile, he would deal with the dark mages later. "No, the rule is no more killing"

"No more killing?"

Makarov nodded and took Naruto out of the base and as he met with other mages and rune knights. "Makarov who is that with you" A mage asked.

Makarov sighed and told him what he found and when the knights and mages turned to face the dark mages who were pale with sweat dripping down their faces and gulped at the angry mages and knights.

Their fates were sealed. When the council judged the dark mages with the evidence they got, let's just say those dark mages won't be see ever again.

"Now onto the child" One of the council members said addressing the new topic. "What should happen to the child they used"

Makarov then spoke up. "I offered him a spot in Fairy Tail"

"What?" A council member asked. "You read what they had that child go through"

"I know" Makarov said. "But people who join Fairy Tail come out with a much more positive outlook"

"That is true" A mage said. "Many who joined Fairy Tail do come out better emotionally"

Another mage spoke up. "The boy already seems to trust Makarov already and I suppose you already told him about the guild correct?"

Makarov nodded. "I told the boy everything about light guilds"

A member of the council sighed. "It is settled then. The boy will join Fairy Tail as a light mage for rehab" Makarov smiled and left the council.

Makarov got Naruto a cleaner set of clothes and took him to the guild. He asked Naruto what colour he wanted his guild mark and where, Naruto replied with orange with a blue outline on his right arm just below the shoulder.

After Naruto made Naruto a mage of Fairy Tail the whole guild threw a party, shocking the blonde. Makarov knew he had Devil Slayer Magic but he didn't know what element he had and he decided to ask as the party was in full swing.

"What type of Devil Slayer Magic do you have Naruto?" Makarov asked the blonde as they sat away from the party.

"Sky Devil Slayer Magic" Naruto said. "It has both offensive and supportive spells"

"Since its slayer magic, can you eat your own element?" Makarov asked as the newest mage of Fairy Tail nodded.

"Master"

"Hmm yes Naruto" The guild master drank from a mug that was filled with alcohol.

"I'm I a monster" He said as he looked at his hands. "I overheard that a monster kills people and the dark mages referred to me as a monster"

"Naruto you are not a monster, let me ask you a question. Did you enjoy taking their lives?"

"No…"

"Then you're not a monster" Makarov said taking a sip from the mug. "If you enjoyed taking their lives then you're a monster. You had no choice but to kill for them, their the monsters not you"

Naruto had a small smile on his face. "Thanks old man"

Year X777

A blonde teenage walked into the guild with a smile. "Sup old man!" The blonde waved at the old short man sitting on the bar.

The old man laughed. "Hello to you too Naruto" Makarov said. "At least he is not cold and emotionless anymore, I'm glad"

Naruto glanced over to a table and back to the master of the guild. "New members"

Makarov nodded. "They are new members" He said as he looked down at the job request. "Was there any difficulties?"

Naruto shook his head. "Nah it was pretty easy"

It was amazing how in such short time that Naruto became so full of life and energy. Makarov smiled as he glanced to the job, it was a demon slaying job, and a pretty strong demon as well.

A demon of Zeref to be precise, it was a dangerous job to take on a demon of Zeref but Naruto's Devil Slayer Magic made short work of it.

"Hey if it isn't the airhead" A voice called out from the distance as Makarov groaned.

"God damn it Laxus, the guild was recently repaired!" He thought. His grandson Laxus and Naruto had a bit of a rivalry, lightning against wind. They got into a lot of fights much like Natsu and Gray but the damage was much, much larger.

"Hmm did you say something battery?" Naruto said as he looked at Laxus with a bored look while Laxus got an annoyed look.

"You got something to say!" Laxus yelled.

"I do have something to say just not to you!" Naruto yelled back.

Naruto and Laxus stood in front of each other as lightning course around Laxus and spread throughout the guild while wind swirled around Naruto and through the guild as well.

"Get down!" One mage said.

"Quickly get the kids out of here!" Another said.

Macao Conbolt, one of the mages of Fairy Tail grabbed Natsu and Gray while another mage grabbed Erza and Cana.

"Does this always happen?" Cana asks the older mage.

Macao sighed. "Yeah, those two are like oil and water" He said.

Just as the two mages were about to duke it out two large hands slammed them into the ground. "What did I say about you two fighting?" Makarov asked the two mages.

"Take it outside" They said in unison.

"What else?"

"Make sure it is miles away from the guild and civilization" They once again said in unison.

Makarov's hands let go off the two as the lightning wind duo stared at each other intensely as lightning came out of Laxus' eyes and gusts of wind came out of Naruto's causing the wind and lightning to clash.

Makarov sighed as he remembered one of the fights that levelled the guild, well more of the aftermath he saw when he came back.

Flashback

Makarov's jaw dropped at the sight he saw. "W-WHAT HAPPENED TO THE GUILD"

Laxus and Naruto who were in the middle of the guild with their elemental magic coursing around them, they both turned around to see an angry Makarov.

Later the two were sitting next to each other as Makarov looked between the two. "Do you two know why you're here?" He asked them.

"No" Both of them said sarcastically.

"DON'T LIE STRAIGHT TO MY FACE!" Makarov shouted comically before he regained composure. "If you two are to fight ever again do it away from the guild or keep the damage to a minimum"

"Fine" They both said and Makarov then learned that keeping damage to a minimum was exactly what happened to the guild.

Flashback End

Makarov shook away the thoughts as he looked up at Naruto and Laxus. "I have a job for the two of you"

"Huh?" they both said.

Makarov handed them a job request from the council, like the ones Naruto took but this time it wasn't for demons, it was a job to disband a dark guild. They both looked at the job and with a grunt from Laxus the two left.

"I want to fight them!" Natsu shouted.

"Like you can defeat them flame brain" Gray said to Natsu who turned around.

"What did you say you stripper!" Natsu shouted back before they started to fight each other.

"Look what you two did!" Makarov shouted in his mind.

"Come on Mr Zappy, the faster we do this the quicker we can stop being around each other" Naruto said as Laxus' eye twitched furiously.

"What did you just call me hot air balloon!" Laxus shouted.

"You heard me Zapdos"

"I can't wait till we finish this stupid request" Laxus muttered with a scowl.

"You and me both" Naruto thought as they walked to the job.

Laxus glared at Naruto who had a smirk on his face. "Don't you dare even say it" He said.

"I don't know what you're talking about" Naruto said with a smirk as he looked out the window of the train they were in.

"Don't you dare talk about this to anyone" Laxus weakly threatened causing Naruto to laugh. Laxus was sprawled out on the train seat as he was suffering from motion sickness.

The train stopped and Naruto had the job of dragging or carrying Laxus out where they waited until he recovered from his motion sickness. Naruto didn't need to take the train due to his magic but that would mean Laxus would have to go on the train alone.

Naruto and Laxus came up to an old building away from civilization. "One with the most defeats wins?" Naruto asked the Dreyar.

The Dreyar turned to him with a smirk. "Think you can keep up?"

"Hn, that's my line" Naruto replied as they both headed to the building. As they approached the building Naruto stopped. "Flight" Naruto whispered as he started to fly as he hovered above the ground as Laxus watched.

"Wind Wall" Naruto shouted as her created a tornado around the old building. After nodding to Laxus they both rushed in with Naruto flying in from a different entry point.

Naruto didn't only have his Sky Devil Slayer Magic as he also had Wind Magic and Air Magic. Naruto only used his Devil Slayer Magic against demons and devils, and the occasion strong opponent.

A few dark mages saw Naruto and went to attack him. Naruto clapped both his hands together. "Magic Wind Palm" He said releasing a highly destructive tornado.

The dark mages where sent into the wall, as Naruto continued onwards taking out some of the dark mages. Naruto landed on the ground as he dodged a fireball from a mage.

"You bastards" The dark mage said as Naruto smiled. "What are you smiling at your surrounded and outnumbered by us" The dark mage said as nine other dark mages appeared.

Naruto raised his hand. "Aerial" He said as a dome surrounded the area with him and the nine mages lowering the oxygen within the dome as a sharp pain within their ears as they started to suffocate.

Naruto cancelled the spell as the nine mages fell to their knees as he then easily knocked them unconscious.

"We're trapped!" A dark mage shouted.

"How do we get out of here?" Another mage asked.

"I see your looking for an exit" Naruto said as the dark mages turned to him.

"I-It's the Devil Incarnate!"

"It's the Exorcist!" The other mage said and it was kind of true. Devil Slayers were known as Exorcist Mages.

"What is an Exorcist Mage doing here?" He asked his partner, despite Naruto not showing off his Devil Slayer Magic he was called Exorcist or Exorcist Mage due to many demon related jobs he took.

Naruto looked between the two mages before coughing into his hand making the two dark mages stop talking and turning to him.

"You didn't forget about me…did you?" Naruto asked as wind swirled around his fists.

The two mages stepped back but the first dark mage 'fell asleep' with a single punch. Naruto turned to the other mage who raised his hands into the air, the dark mage released the breath he was holding as Naruto wouldn't knock him out.

How wrong he was.

The second dark mage fell down and Naruto proceeded to use wind magic to carry the unconscious bodies with him.

Naruto cancelled the Wind Wall around the old building and him and Laxus turned in the dark mages and they were returning back to the guild.

"You got lucky balloon boy" Laxus said.

"Hmm, like you could do better than me Zapper"

This is what the guild heard as they both walked inside the guild. "I take it the job went well?" Makarov asked the two mages.

"The job went fine" Naruto said.

"Too easy" Laxus told his grandfather.

"You are free to do whatever" Makarov said as the two instantly walked away from each other. Makarov shook his head with a smile, even if they don't admit it they were the best of friends as well as rivals.

Naruto walked past Natsu and his nose twitched, he was covered by a reptilian smell but there was a smell underneath, it was tiny and almost unnoticeable to everyone.

He smelt a demon, as a devil slayer his magic was used to kill demons but Naruto wouldn't do it despite Natsu having the faint smell of a demon on him, he was a comrade and Naruto didn't kill his family, the guild happened to be his family.

Naruto just smiled at Natsu and kept walking. He would trust that little lizard.

Naruto walked to see Cana about to pick up a mug that someone just left there, Cana probably didn't know what was in the drink so Naruto picked up the mug from her.

Cana was a young girl with long wavy brown hair and purple eyes wearing a green dress and a blue arm band around her left arm.

"You shouldn't be drinking this Cana-chan" Naruto said as he placed the mug on bar.

Cana pouted. "Why not"

"Because its alcohol" Naruto said. "You should wait until you're of legal age before you drink it"

"But legal age is a long time" She said.

"Well you just have to wait" He said as she looked down. "But there is a legal age for mages though" Cana looked up.

"There is?"

"Yeah, why do you think Laxus has a mug sometimes" The Exorcist Mage said. "You can have it when you're of legal age, I don't know if you had this before. Did you?" He asked as he saw her nod.

Naruto sighed before he ruffled her hair. "Is this your second?" She nodded again.

"I only had a little sip last time"

Naruto smiled at her. "If you don't drink any of this until you are of legal mage age, you are allowed to drink" Cana looked up. "But only if you start after the required age"

"Aww" She gave him a puppy look.

"Don't give me that look" Naruto said. "Do you promise?" Cana nodded.

"If you keep your promise than you can drink" The blonde told the brunette. "If I find out you drank before you come of legal age… then you won't be drinking this stuff ever again"

"I'll keep my promise" Cana said as Naruto smiled and ruffled her hair as he walked away.

"I hope you do"

Naruto went to the job request board and noticed a job for him. To remove a demon in the village, to him it smells suspicious. He would go on the quest and he would look underneath the truth.

Why would a town send a request to take care of a demon if said demon was still in the town and there was no reports of any deaths of the townspeople.

There was something off with the request and he was going to find out what was so suspicious.
