Professor Dragneel, at Hogwarts

**prelude**

Fairy tail. Name known throughout the Earthland. It's the name of the guild that destroyed Alvarez Empire. But one particular member is even more famous then Fairy tail itself. Where ever you say this name it will be fallowed by cheers and happy shouts as well as admiration. Well now... I'm sure you wanna know who is that extraordinary young man. A mage who defeated Zeref. A mage that is Zeref's brother himself. A demon E.N.D. Son of Igneel, fire dragon king and fire dragon slayer nonetheless. Well he is none other then Nastu Dragneel... or if you want his full name Etherious Natsu Dragneel.

Chapter 1:

It's been normal day at Fairy tail... Well as normal as it can be with Fairy tail members.

Makarov was sitting on bar with beer in his hand smiling at his children. It's been three years since war with Alvarez Empire. And three years since Natsu found out he was E.N.D. and Zeref's brother. It took a while for everything to get back to normal after that but now they are all big family they once were. The guild right now had it's usual fight.

"It's wonderful guild, you know that, eight" said small blonde haired girl that was sitting next to Makarov with her feet waving happily beside her just as table flew beside her.

Few things also changed over the years... for example this fight wasn't started by a certain pink-haired dragon slayer and ice devil slayer whose name I won't say *cough* last name Dragneel and Fullbuster *cough*

It was started by black haired boy, umm... I mean he's teen now, eighteen years old teen and that teen is one and only Romeo Conbolt.

"Surely it is..." Makarov said as he looked at the table that crashed behind him and sweat-dropped.

There was loud BOOM that didn't seemed to bother anyone since it was just doors of the guild. They all smiled since they knew all too well who was on those doors. A loud shout just confirmed what they already knew. They favorite demon was home.

"MINA! I'M HOMEEE!" said a pink-haired twenty years old man with blue cat on his head.

"Hey Natsu! How was the mission?" Elfman asked with big smile while holding one beaten in his hand.

Natsu looked at where he heard Elfman's voice. "Those S-class missions are just to easy! I'll maybe take SS-class next time!" Natsu exclaimed with grin and continued walking toward bar to give Master report of the mission. Oh yea.. Natsu became S-class wizard year after he defeated his brother.

"AYE! He beat that monster with barely any magic!" Happy said as he stood on Nastu's head with fist pumped up in air. Happy looked around guild with smile and then spotted Charla sitting next to Wendy and with one sweet 'Charlaaaaaa~~' he flew to her.

"I bet I wouldn't use any magic!" came a shout from crowd as naked raven-haired man jumped in front of Natsu.

"What did you say, Ice-princess?" Natsu asked as he glared at man but still kept his smile.

"You heard it, flame-brain!" Gray shouted also with smile of his own.

Two young men ran toward each other with their fist cocked backwards ready for punch but few seconds before their fist touched a certain red-haired woman stood beside them.

"Are you boys fighting?" Erza asked in dangerous tone with reddish glow in her eyes.

That stopped them. They put their hands back down and quickly shook their heads saying "Of course no!

Erza looked at them suspiciously measuring them from head to toe but after few moments of staring at them she nodded satisfied and went to bar to get her beloved strawberry cake from Mira.

Levi, Lucy and Mira who watched that while sitting at bar (Mira cleaning cups) sweat-dropped.

"Gray is Ice devil slayer..." Mira said

"Natsu is E.N.D..." Levi sighed.

"And I'm still wondering who is real demon here every time I see Erza..." Lucy said and all three girls sighed in union while shaking their heads.

Makarov chuckled and Mavis giggled. Nastu sat next to Makarov and started to tell him about his mission when doors opened once again but this time instead of a person an long-eared owl flew in the big hall.

Those who saw it started talking about it while watching as it flew across entire hall, with letter in its beak, and flew toward Makarov who raised his eyebrow in wonder. The owl landed between Makarov and Natsu and gave Makarov the letter in his lap with loud screech.

By now whole guild watched as Makarov opened the letter while muttering under his breath "It's been a while since I last get any letter from Albus..."

"Uuuu! It's form Albus?" Mavis asked happily as she stretched her neck to see the letter. He opened the letter and started to read while Natsu also stretched to see what was inside.

It said:

My dear friend Makarov,

as you know I am the headmaster of school known as Hogwarts. In past few years some dangerous things started to happen in my school and this year we are having The Triwizard Tournament in our school. In order to secure my students and especially a young wizard named Harry Potter I would like to request that one of your children come to Hogwarts to protect them while working there as a professor. I had one particular member of your guild in my mind. I heard that he knows how to speak Draconian as well how to read it so I would request presence of Mr. Etherious Natsu Dragneel in my school.

I'm sorry to say that he will have to come alone since I can transport only one person. This would be rated as S-class mission in your country if I'm not mistaken and it would last from begging to the end of the school year.

I will be glad to pay as many as young wizard wants.

I'll come to get Mr. Dragneel one week after I get your response for this mission. You can send your answer by giving this owl a letter.

Sincerely

Headmaster of Hogwarts, Albus Percival Wulfric Brian Dumbledore.

Makarov put his hand next to him in front of owl only to get bitten by it.

"Ouch!" he said more in surprise then pain and looked at letter one more time.

On the end of the page letters seemed to appear:

P.S. Watch out, owl bites.

Makarov looked at the letter surprised. It must be really dangerous there for Albus to request such thing.

"Interesting..." came Mavis's voice next to him.

"So it means I can't even bring Happy?" came Natsu's voice from behind him that made him jump slightly since he didn't saw Natsu moving behind him.

"No I'm sorry Natsu but you can't. You have to go on this mission alone... I mean if you want to go" Makarov said with sigh.

"Oh mann..." Natsu whined but quickly looked at Makarov like he just said the most stupidest thing in whole Earthland.

"What are you saying old man?! Of course I'm going! I never turned down any mission and this one request for me specifically!"

"Ummm... What's the matter, master?" Lucy asked as her attention was drawn to their little conversation after Natsu's little speach. Makarov and Natsu then explained what was in the letter.

**after explanation**

Gray burst laughing "Whahahah! Flame-brain, professor!? That's hilarious! That joke is just brilliant!"

On Natsu's forehead vain popped out "It's not a joke Snowman. They really needs me to be their professor"

"So that means you'll be gone for whole year?" Happy asked sadly.

"Yea... sorry buddy..." Natsu said as he put his hand on Happy's shoulder.

"Well you better start packing..." Makarov said.

"Yeah..." Natsu said. He was about to leave when Wendy came to him and said "I didn't know you know how to speak draconian"

"Of course I do! That's the first thing I learned from him!" Nastu said and then said again "Ano nakarame era! Which means 'And I'm prud of that!'"

"Whoa! I had no idea there was someone who still knew that language!" Mavis said with smile and childish awe on her face.

Natus laughed and said "Well, I better start packing" he turned to leave when "Oh and Natsu!" Makarov called out and Natsu turned his head.

"Yes?" he asked.

"You'll have to wear normal clothes" Makarov said with smile and creepy glint in his eyes.

Natsu raised his eyebrow when he turned his whole body toward Makarov. "What's wrong whit this?!"

Natsu pointed at his robes. He was currently wearing black coat with golden outlines, the one he wears after Grand magic games only these one didn't have any sleeves, white pants, sandals and his white scaly muffler.

"It's not something everyone would wear" Lucy said and other nodded. Natsu sighed "Then I need to get some new clothes..." he muttered but others heard him.

"Oh no problem with that Natsu! I already requested girls to help you buy new clothes!" Makarov said.

Natsu's mouth opened to protest but girls were quicker.

"Yeaaa!" Lucy and Mira screamed

"I can't wait!" Erza said with stars in her eyes

"Oh! I'll come too!" Wendy said with smile.

Erza took Natsu by the collar of his shirt and started dragging Natsu who was kicking and screaming how he can buy his own clothes.

**time skip- one week later**

Nastu sat in guild hall waiting for this Dumblidor or something to get him. He already said goodbyes to everyone and now was just sitting in silence with Happy on his head and Team Natsu beside him. Others left a while ago since it was really late. He looked at his new clothes. It took them three whole days to buy everything since girls couldn't agree on only few things. He shivered at thought of them dragging him across whole Magnolia and making him try everything they saw.

He was now wearing light blue shirt with black coat, black pants and black leather shoes. And of course his white scaly scarf was around his neck.

"Well it seams he's not coming tonight" Natsu said breaking the comfortable silance and just as he finished that door of the guild opened and an old man, and I mean really old, came walking in with an old woman.

The old man, known as headmaster of Hogwarts, Albus Dumbledore was tall and thin, with silver hair and beard so long that they could be tucked into his belt. He had a very long and crooked nose that looked as if it had been broken at least twice. He also had long and skilful fingers. His eyes were a brilliant, soul-piercing shade of blue, and twinkled with kindness and mischief.

The woman next to him was none other then professor Minerva McGonagall. She wore emerald green robes or her favorite tartan pattern. She also wore a pointed hat cocked to one side, and always had a very prim expression. She her black hair was put into a tight bun.

Makarov stood up and smiled at his old friend.

"It's been long time, Albus" Makarov said with smile.

Albus chuckled "Indeed it was, Makarov, Mavis."

They started talking about 'good old days' but Minerva cleared her throat reminding them why are they here. She scanned small group who started introducing itself

"My name is Lucy Heartfilia, celestial spirit wizard"

"Name's Gray Fullbuster, ice devil slayer"

"My name is Erza Scarlet, I use requip magic known as 'The knight'. It's pleasure to meet you"

"I'm Happy!"

"My name is Wendy Marvell, sky dragon slayer"

"You must be Mr. Dragneel?" Albus asked before Natsu said anything.

Natsu nodded "My name is Etherious Natsu Dragneel but you can call me just Natsu, I use fire dragon slayer magic as well as my demon's curses"

Albus smiled "My name is Albus Percival Wulfric Brian Dumbledore and this is Madam Professor Minerva McGonagall, it's great pleasure to meet so many great young wizards"

They talked some more but then Dumbledore asked "Are you ready to go?"

Natsu grinned at old man "Yup"

"Then lets hurry" Minerva said "The school starts in one month and we need to be there tomorrow so you can learn everything you need to know about school"

Albus chuckled at his friend "You don't need to be in such hurry, Minerva. We won't be late. We still have plenty of time left."

Minerva looked at Albus but didn't say anything.

"Well.. how are we going to get there?" Natsu asked fearing he'll need to get in train. He took his large bag and put it on his shoulder readying himself to get going.

Albus's eys twinkled as he took from his coat an old looking boot. Natsu raised an eyebrow.

"What's that?" he asked not sure if they wanted him to wear that boot or something.

Albus smiled and said "It's a portkey. It will take us to Hogwarts"

"Portkey..." Natsu's eyes widened in realization and then he shouted happily "So no trains?! No cars?! No vehicles?!"

Minerva looked at Makarov puzzled. Makarov sighed "He have bad motion sickness, all dragon slayers have it"

Minerva raised an eyebrow and nodded.

Albus laughed at young man's happiness "No, there will be no vehicles"

"Alright!" Natsu yelled with fist in air. This is great! Maybe he could get the old man to give him that boot.

"So how does it work?" Natsu asked once he calmed down in puzzled voice.

"Just put your finger on it" Minerva said.

Dragon slayer nodded and put his finger on old boot.

Minerva did the same and Albus was already holding it.

"One" Albus counted.

"Goodbye mina!" Natsu shouted and everybody yelled "Bye Natsu"

"Two"

"Three"

And with that everything around Natsu and two wizards started spinning. Natsu's eyes widened in horror 'This is even worse then vehicles!' and he turned green and his cheeks puffed while he tried not to puke.

"Let go" Albus said with smile. He and Minerva released they hold on boot and Natsu soon after them.

"AAAAHHHHHHH!" Natsu screamed when he saw he was approaching the ground at alarming rate.

With thud Nastu hit the ground with his face in dirt. He lifted his face to see Minerva and Albus practically walking down the sky and landed gracefully.

He spit grass he had in his mouth and stood up grumbling how they could say that it was this bad while also saying "I'll never touch that boot again"

He was about to say something as he looked up and glared at Dumbledore and McGonagall only to see giant castle behind them. His jaw opened in surprise. He was pretty sure that it was even bigger then King's castle in Fiore.

"T-that's...?" he couldn't find the words so he just pointed his finger at it.

"Welcome to Hogwarts, Hogwarts School of Witchcraft and Wizardry" Minerva said.

"Whoa..." Natsu said amazed at size of the school.

"Professor Dragneel, from tomorrow you'll be professor of Draconian, you'll teach students that will arrive here how to speak it and how to read it and if you wish you could teach my students self-defense since I heard you're good in martial arts" Albus said with kind smile while his eyes twinkled with kindness.

"Professor Dragneel... I like how that sounds" Natsu said grinning.
