Here is the Pomise of the Fire Dragon.
In Fiore is, surrounded by a big and dark forest a small Village known for its strong magicians.
However this Village is currently being completely annihilated by Acnologia the Black Dragon of destruction, standing on a Mountain and watching the scene is a man known as the strongest of all dark mages: Zeref.
"Acnologia became quite nervous since the wings spread, well my magic is boiling too. I want Natsu to kill me, but I think I have to wait until the Dragonslayer King is chosen. Natsu I hope Acnologia gives you chance."
Natsu stood in front of the guild door stretching and warming up so that he could kick it open he already took of his coat and folded it into a scarf. In the guild the tension in the air was almost physical as everyone stared at the door waiting for the stranger to come in, especially Gray as he had some business with the new member.
"Bam! The door swung open and in the doorframe stood a smiling Natsu, very happy because of his entrance.
"Hello guys!"
The guild responded with a barrage of glairs and dark looks Gray even tried to run up to him but was stopped by Erza.
"Hello… I forgot it yesterday but before you join, whats your name?" The Master asked.
"Oh! I didn't tell you? My name is Natsu Dragneel."
"I see, also you have to swear that you won't bring harm to Fairy tail."
"Yes I already said that yesterday, didn't I?"
"Yes yes but you have to swear it."
Natsu thought for a second before he suddenly became enraged.
"Are you saying that I have to do the Kasai chikai? (That's Japanese for fire oath.)
Makarov was dumbfounded, he didn't know what the Dragoslayer meant.
"N-No you just have to swear it." A few of the guild members were scared but most of them looked like they were ready to step in everytime.
"Yes of course, sorry for my reaction, my experiences with oaths aren't very good." Natsu said while shaking his head.
"Well are you ready?"
"Yes"
"I, Natsu Dragneel declare, here and now that I will refuse to harm or betray Fairy tail in any way. Is that enough?"
"Yes Natsu that should be enough, Mira?" Makarov called for Fairy tails bartender.
Mirajane stepped out of the crowd she held a stamp in her Hand and seemed to be the only one, besides Natsu who smiled.
"Where do you want your guild mark and in which colour?" Mira asked Natsu
"On my right arm and in read please."
Mira put the guild mark on Natsu's arm and stepped back.
"Ok old man I'm now an official member right?"
"Yes you are now a member of Fairy tail"
"Okay great can I ask you something?"
"Of course"
"Why exactly is everyone standing back like I'm poisonous? I don't know if it's just me but I would celebrate every new guild member, I mean the more the merrier, or not?"
The guild was shocked as Natsu spoke like he was already a guild member for Years.
Suddenly Master Makarov started laughing.
"Hahaha I'm beginning to like you Natsu, you're right that means lets party!"
As Makarov spoke this, the Tension that Natsu already knocked out was basically grabbed and thrown out of the Window as the guild members started partying. They started drinking, brawling and talking Gray used it to fight Natsu. They also asked Natsu a lot of things, why he is so strong where came from and what's his story. Only Erza stood behind and observed Natsu waiting for him to make a mistake so she can bid the Master to kick him out. In the evening Natsu left to get enough sleep.
"Okay Natsu, but please come to my office tomorrow." Makarov said.
"Sure, see ya tomorrow."
In an ancient Temple far away a young man comically fell over after reading a letter…
