Fairy Tail was fighting Tartaros. Almost everyone in Tartaros was defeated; the only one left was Jackal. Everyone in Fairy Tail had gathered together ready to defeat the last person when a black mist apperard. Zeref stepped out holding the book of E.N.D and another one that read E.L.S.

"Hello there Fairy Tail. I've waited a long time to see how strong these demons would become and I'm happy to say that they have come along nicely. Better than I could have ever hopped. Now to realise them." Zeref said

Zeref opened both of the books blakc magic surrounded the books before surrounding Natsu and Lisanna. Before the guild has any time to react the balck mist disappears leaving the demon forms of Natsu and Lisanna. ( i'm going to put links at the bottom to show what they look like and art doesn't belong to me)

E.N.D and E.L.S walked over and stood my Zeref. Both having a creepy facial expression. They didn't have their Fairy Tail marks anymore. They were replaced with Tartaros marks.

"What the hell have you done to them." Makarov yelled

"Alright if you really want to know i'll tell you only because I'm bored but I hope that whatever mate they get is good. I don't need more trouble then I'm going to have to deal with already." Zeref said

The atmosphere was heavy. No one dared move or speak. What were they supposed to do? Two of their guild mates were demons of Zeref. They wanted to defeat the demons but couldn't bring themselves to attack even though they were demons now.

"Zeref. How are these two demons? I've raised those two since they were kids. Natsu's dragon left him and Lisanna has human siblings. They were not born demons so tell me why are they demons now?" Makarov stated.

"You were always a bright one Makarov or from what at least i've heard. They were not demons originally. They were human but because of both of them dying at one point I put a demon in their bodies to keep them alive." Zeref said, smirking at the facial expressions of the guild.

Makarov took a couple of minutes to take in this information. Both of them had died at one point. He remembers Lisanna's death but Natsu never died or at least that's what he knew of. Makarov looked over at the rest of Fairy Tail. They had horrified faces. Mira was crying while Elfman was trying to comfort her while his own tears. Lucy was also crying. She was trying her best to hold back and no one noticed because the rest were looking at Zeref, Natsu, and Lisanna. They looked like they were ready to attack Zeref but what about their mates. Do demons even have mates or is it because of something else.

"Alright Zeref. Tell me about how these two became demons and about this mate that you have mentioned. Makarov said looking Zeref straight into his cold eyes

"Alright Makarov. If that's what you want then I'll start with the explanation of how they became demons. E.N.D is my younger brother. He had died to a dragon 400 years ago along with my family. I created a demon strong enough to rule and out him inside his body bringing him back to life. Before I could do much else a dragon stopped me and sealed the demon away temporarily and trained him. They were then sent to this time along with the other people trained by dragons. My full name is Zeref Dragneel and my younger brother is Natsu Dragneel. Oh and the book of E.N.D stands for Etherious Natsu Dragneel."

Everyone turned to Natsu who was looking at them as if he didn't care. How could he be the strongest demon. He had always helped people and was kind. But looking at him now it kinda made sense since he used fire and was strong.

"Now for Lisanna's demon story. I was working on a new demon just as strong as E.N.D but I didn't know who to test it on considering that the person would have to be on the brink of life and death just like Natsu was. I was walking around the forst when a girl came flying towards me and hit the ground hard. She was badly injured and almost dead so I decided to put the demon inside of her and name it Etherious Lisanna Strauss. I then disappeared to go make her book and I guess she was somehow sent to Edolas."

Now everyone was looking at Lisanna. Had her death really caused all this. She was a demon now just like Natsu and the rest of Tartaros. Both of them were gone.

"ZEREF. DO YOU REALIZE WHAT YOU HAVE DONE TO THIS WORLD. YOU MIGHT BE THE MOST POWERFUL WIZARD BUT I WILL NOT STAND FOR THIS. YOU HAVE TAKEN TWO OF MY CHILDREN AWAY FROM ME FOR WHAT, MORE POWER OR OTHER SELFISH REASONS. I WILL NOT LET YOU TAKE ANYONE ELSE." Makarov yelled furiously.

"I would have thought you would have had better control of yourself. You cannot stop me as long as I have followers, my demons, and their mate." Zeref

Lucy's p.o.v

This doesn't make sense. Why would he openly tell us about them and his past. Isn't he supposed to be the one that just does what he wants. The fact that he's telling us all this means he wants us to react to it or do something. I also don't like the way that they're looking at me. I've seen Zeref take glances at me and I can see Natsu and Lisanna looking at me but the look in their eyes seems kinda lustful. Well whatever that look is I don't like it.

I felt someone put a hand on my shoulder. I jump a little before turning to see Gray. He knew of my feelings for both Natsu and Lisanna. I was afraid to interfere with their relationship. Before this had happened they had been hanging out a lot with each other and I heard people talking about them getting together so I stayed out of the way and hid my feelings.

I was crying into Gray's shoulder when I felt a dark aroma behind me. I ignored it thinking it was Juvia but when I saw a fireball hit Gray and felt arms, a tail, and wings wrap around me holding me close.

Lisanna was the one holding me close in a tight grip not tight enough to hurt but tight enough so I couldn't get out. Natsu was standing in front ready to fight Gray. I attempted to wiggle out but she just tightened her grip even more and let out a low growl causing me to freeze.

"Get your filthy hands off her. Never touch her again. You got that ice freak." Natsu yelled

"What the hell do you think you're doing you demons. I don't care that we were guild mates. You're no longer Natsu and Lisanna that I have known. So how about you tell your demon friend to get her hands off Lucy fire breath." Gray yelled

"What'd you call me droopy eyes"

"I called you fire breath. You gotta problem with that dragon boy."

"Don't start with me ice boy. You're not gonna win this."

"I'm not gonna stop until you give Lucy back to us. Now give Lucy back right now you two or else were going to have a problem."

"No. I'm not letting you touch what's mine. Luce belongs to me, Lisanna, and the Tartaros guild. She's our mate so you're not gonna have her anymore."

I completely froze. I was there mate but that was impossible right. I turned my head to look at Lisanna or whatever this demon was and she was smiling. I looked back at the guild with a horrified face. Lisanna put her head in the crook on my neck and started purring. I couldn't take all this information in so I started crying. Lisanna and Natsu seemed to notice this quickly. Lisanna started purring more and rubbing her head against my neck while Natsu hugged me from the front the same way Lisanna had me against her and heated his body up a bit to make me feel warm and safe.

I should have felt disgusted and uncomfortable. I should have tried to get out of their embrace or weird hug but it made me feel loved, wanted, safe, warm, and more. It gave me a sense of security that I haven't felt since my mom died. All of a sudden they were pulled away from me and I was pulled into a plate of chest armor.

I was now standing by my guild mates while the two demons that had me were not happy anymore. They looked ready to kill. Fairy Tail stood in front of me ready to protect me against the demons. Zeref was looking at me with an unreadable expression. We just won a war and now we might be fighting another one right after.

"E.N.D and E.L.S. Let's leave these fairies alone for now and don't worry we'll get your mate on a later day. Since Miss. Heartfilia isn't eighteen yet i'll give her until her eighteenth birthday which is about a week or two away. I'll let you say goodbye to your pathetic guild before you become queen of Tartaros. Bye for now Fairy Tail." Zeref said before turning around

Zeref was now walking away and Jackal followed not far behind him. The two demons stayed looking at me. Gray, Juvia, and Gajeel blocked me from their view and they finally left. As they were talking away the stress from the war and this news causing me to pass out.

( The links for the pictures wont work so just look up demon form of Natsu and demon form for Lisanna. That should give you the images for what they look like.)
