Gray stared at the transformation. His best friend was turning into a demon, and he could do nothing to help.

Father walked away from the wizards and stared at Natsu. Natsu looked like a wild animal that has been trapped for over a thousand years.

"My son" father whispered. He began walking to Natsu. Natsu's father could feel the demonic power coming from Natsu.

Zeref quickly grabbed hold of the fairy tail Wizards, he teleported Gray and Juvia first, and then Wendy, Happy and Erza. Lucy saw her friends disappear in less then a second.

"What the hell did you do?" Lucy cried, before she got an answer, Zeref grabbed her arm and teleported her to where the rest of the Wizards were.

"What's wrong? Afraid that I'll hurt the little Wizards?" Father laughed in Zeref's face.

Zeref teleported to Natsu.

"Sorry, Natsu" Zeref whispered to him silently. He tried to punch Natsu in the stomach to knock him out but Natsu grabbed Zeref's wrist.

"Don't, touch me" Natsu growled angrily at Zeref. He let go of Zeref and went face to face to his father.

"Natsu, my boy. Join me. Take your brothers place and serve me. We can create a new world where you and I rule" father said with no fear. It was the first time, in a long time, that he actually mentioned Natsu's name.

"I'm going to kill you. I'm going to put my fist through your chest and watch you bleed...No, I'm going rip off, one limb at a time, and watch the life leave your pitiful eyes" Natsu's tone was dark, the tattoos spread all over Natsu's body, horns began to grow out of Natsu's head.

Natsu smiled sadistically, the thought of torturing his so called father, made him feel more alive than ever.

"So be it. I'll crush you and your little fairy friends" Father shouted at Natsu.

Father created a orb made out of pure darkness. The orb grew bigger and bigger. Natsu smiled at his father, he lit his hand in pure dark flames.

Father threw the orb, which was now the size of a car at Natsu. Natsu charged towards the orb, ready to disperse the orb with his dark flames but Zeref teleported to Natsu and teleported them both out before the orb hit Natsu.

Natsu and Zeref were now standing in the middle of a Forrest like setting.

Natsu looked around his surroundings and notice that they were back in a forest. He glared at his brother who stared back at him with no emotions.

"What the hell did you do?" Natsu shouted, the black flames were starting to surround Natsu's body.

"Brother, you need to calm yourself down" Zeref spoke in a calm but stern voice.

"Calm down? YOU WANT ME TO CALM DOWN? I JUST WATCH MIEKA DIE IN FRONT OF ME. HE ALSO THREATENED MY COMRADES. WHO EVER THREATENS MY FRIENDS WILL DIE BY MY HANDS" Natsu shouted at Zeref, the earth beneath them began to shake. Natsu clenched his fist, the nails dug deep into his hands. Black blood poured out of the wound on his hands.

"Natsu, stop this. If you continue this, then you'll become the demon that father always wanted you to become" Zeref shouted back at Natsu through the wind. The trees around them blew harder, the rocks began to crumple and the fire that surrounded Natsu grew more intense.

"Maybe, it's about time I embrace who I am" Natsu stated firmly but softly. The flames that surrounded Natsu extinguished, the wind slowed down and the rocks stopped rumbling.

Natsu closed his eyes. The horns slowly went back into his head, the tattoos began to slowly disappear and his eyes turned from red to black.

"Natsu, what are you going to do?" Zeref asked his younger brother. He knew that the darkness was already starting to consume him.

"Where are my friends?" Natsu asked. He looked around the forest and saw nothing but trees and rocks.

"I can take you to them" Zeref said, he walked up to Natsu, cautiously. Natsu had a distant look in his eyes.

"Natsu?" Zeref spoke softly. He put a hand on Natsu's shoulder.

"Brother?" Natsu spoke softly. Zeref looked at his brothers sad and lonely eyes. Zeref nodded his head.

"I need a favour from you" Natsu stated

"Where the hell is that flame brain and that stupid black wizard guy?" Gray shouted, one minute he was watching his best friend and rival, turn into a demon, then the next, he was teleported in the middle of the Forrest with his friends.

"Natsu...he was...a demon?" Lucy whispered. Her tears were threatening to fall out of her eyes.

"We don't know that. We can't trust Zeref's word. His the black wizard" Happy stated, he wanted to convince everyone that Natsu isn't some evil demon, but he wasn't sure if he believed it himself.

"You saw him. YOU SAW THE HORNS, THE TATOOS AND THE EVIL EYES RIGHT?" Gray shouted back.

"SHUT UP" Erza shouted, everyone faced Erza.

"Erza...what's happening to Natsu?" Wendy asked softy, she was afraid of the answer, but she need confirmation.

Erza remained silent, she wasn't sure if she understood what was happening.

"Honestly...I don't know" Erza said softly.

"Juvia is worried about Natsu. Natsu wasnt himself. Juvia thinks..." Juvia began to say, but she stopped her self from saying anymore incase she upsets her comrades.

"Juvia, what are you thinking?" Gray asked eagerly, any explanation would be good. right about about now.

"Juvia thinks...Natsu was turning into a demon" Juvia said softly. Everyone stared at Juvia like she was growing a second head.

"Natsu? Our best friend? The person who I've know for my whole life?" Gray shouted at Juvia. Juvia flinched at Gray's shouting.

"Obviously you don't know much about Natsu's past...none of us do" Happy defended Juvia, but then sounded defeated.

"I'm...I'm sorry" Gray apologised to Juvia. Juvia nodded her head
Everyone stood silently, all of them felt ashamed and guilty for not knowing about Natsu's past.

Zeref thought this was a good time to talk to the fairies about Natsu. He stepped forward to get the Wizards full attention.

"You bastard" Gray gritted against his teeth. Gray clenched his fists and lunged towards Zeref. Zeref had no emotions showing on his face

Zeref swiftly moved out of Gray's range and kneed him in the stomach.

"Gray-Sama" Juvia called out to her beloved, she ran towards him and crouched next to Gray. She shot a glare at Zeref who didn't have a care in the world.

Everyone got into there offensive position, ready to attack, if Zeref so much as look at them in the wrong way.

"Where's Natsu?" Lucy asked, her grip tightening on her celestial keys.

"He gave you a message" Zeref said, he took a step towards Lucy, everybody tightened there grip around their weapon or increased their magic.

"What was it?" Lucy asked curiously, for all she knew, this could be a trap.

Zeref gave Lucy a white scaled scarf, Natsu's scarf. A box of letters were written which was attached to the scarf.

Erza grabbed the box out of Zeref's hand, everyone went to crowed over Erza who took out the first letter which was addressed to the fairy tail guild.
There's was a letter each, directed to his closest friends.

Dear FairyTail
I'm sorry for all the trouble that I have caused, I've dragged you guys into something, my past.

I know that you guys will try to find me after reading this note, but don't. Go back to the guild and tell everyone what happened and then, tell everyone to forget.

Instead of wasting your time on finding me, spend your time forgetting me.

Goodbye, Natsu Dragneel

Erza had tears in her eyes, but she wouldn't let them fall. She had to remain strong. A long time ago, Natsu taught her that crying doesn't making you weak, it proved that your human. She began to blame herself for Natsu's leaving. She thought to her self, I was always hard on Natsu this is my fault

Gray looked pissed, not because of Natsu's past, but because Natsu's always the first one to come and help him whenever he needed it, and now that their roles were reversed, Natsu ran away, from the guild, from his friends...from him, his best friend, his brother.

Juvia wasn't as close to Natsu as the rest of the team but Natsu was always there for her. If it wasn't for Natsu, she would never have joined fairy tail and meet Gray.

Wendy...Wendy didn't know how to feel, Natsu was like her older brother. He always protected her, trained her and on multiple occasions, saved her. He was always there for her, when she felt lonely, Natsu was there to cure the loneliness, but now Natsu was gone, now Natsu's alone and she couldn't help him.

Happy felt rejected, and a little bit pissed. His best friend left him, how could he do that to him? Happy couldn't stop the tears on anger and rejection from flowing. He wandered to himself. What did I do wrong?

Lucy couldn't believe it, Natsu Dragneel, her best friend...leaving her? No, leaving the guild, his family. Maybe it was more like denial, she didn't want to believe that Natsu was leaving for good. The worst part of all, was that she never got the chance. The chance to say, I Love You.
