Lucy POV
After defeated the monster and going back to Fiore was nice. I really enjoyed going on a job with them but to bad I didn't find any keys, I really wish to find more. On our way back Natsu said that he wanted to follow me to my house so now Natsu, Happy and I are walking back to my house. Hope they don't go destroy it or go threw my things. Once we reached,  I went to the bathroom to bath and when I come out i see them reading the story I wad writing shesh dont know know anything about PRIVACY I said in my head. After I took the paper back from them, I went to change I wore a white top with blue lines and a blue skirt with my combat boots. When I finished changing I went to place the paper on the desk and before we left my house something caught our attention. It was a key on the floor I've never seen it before, gold but it had a dragon symbol on top and there was a stone the colour of fire and black chains going round the bottom part of the key. I then said that maybe if we bring it to the guild someone would know what key is it and how to call out the spirit. So I took the key and we headed to the guild, its so weird the magic power from the key is stronger then anything I've felt and different its like 2 things are in it. Once we reached the guild, Natsu and I asked master he said he's never seen it before so me, Levy and Natsu went to the library to find out information on the key. So far we've found nothing, Natsu found a porno book which me and Levy sweat drop, after looking for hours we went back to the guild and told master that we didn't fin anything. We were going to give up and forget about it until Loke came out using his own power and told us then he needed to talk to Natsu, me, Erza and Gray. So we followed him, "ok Loke, why did you ask us to follow you?" "Because I need to tell all 4 of you something important don't freak out or get angry" "why would we get angry Loke?" "U-uh I think its better if you see it then you'll understand" "see what Loke?" "Ok Lucy, just say " I open thee gate of the fire king, Phoenix" "what?!Loke w-why did you just say Phoenix??" "Lucy just say it and you'll all see and understand" "I open thee fire king , Phoenxic" then a bright light appeared and suddnely there stood a girl with yellow, pink and red hair wearing a red high low dress. Then when I turned to face Natsu, Erza and Gray they're faces were shocked and surprised and then Natsu said something that made 3 of them cry "Na-Nala!!".

Nala POV
I was suddenly found standing infront of Natsu-nii chan, Ezra, Gray, Loke an I think the girl is Lucy. The 3 of them were shocked I guess I have to explain to them. I should have known Loke was going to ask them to follow him and Lucy and we're standing behide the guild. " N-Na-Nala?!" Natsu-nii chan asked I wish he didn't hesitant to say my name well I guess that's what happens when your gone for a long time or they think you died. "Hi Natsu-nii chan, Gray and Erza" "y-your alive?" "Yea, I guess I have some explaining to do huh?" "Yea you do" "wait before that Nala I would like you to meet Lucy" "hi it's nice to meet you, hope we can be close friends" "nice to meet you too Lucy,  and I think we'll be close friends and more" I said and smiled at her. After we walked to her apartment for me to explain to them, I had a black hood on so no one would see me just yet. Once we arrived we sat in her house and she made tea for everyone she's so kind no wonder Natsu-nii chan likes her or loves her.
"Ok so now explain to us why did it happen and why are you here an still alive?? Why did you come out of that key that Lucy found??!!" "Shesh Gray come down. Wow you're never changed since you were small haha" "just get on with it and tell us " "fine fine. So when we were small still in our kingdom me and Natsu's sister found out a secret that my parents and his parents have been hiding from us and we've found out when Natsu, his parents and my parents wen to visit Lucy and her parents. We  found out that I'm actually a half celestial spirit and my other half is actually in that key but to made that key to exist I'll have to die first but it'll only work if I die protecting the people I love" "so during our fight with the monster you sacrificed yourself for that?" "Yes I did, but it was only to safe you all and for me to get stronger, after that day I was in the celestial spirit demention with the others and they trained me and my other half." "Why didn't you tell me when you found out that time?why, did you not want me to know? Why would you keep that secret away from me?" "Natsu-nii chan I didnt want too but that secret we weren't meant to know but I broke the rule, I'm sorry" I said with tears in my eyes. "Sorry doesn't even cover it" he said it so harshly and just left the room and headed out. I know that I should have told him we were so close, I looked at Ezra and Gray "don't worry Nala, we'll talk to him and Lucy will talk to him too" "thanks Erza" then after that I hugged both of them "oh Lucy before I forget, do you wanna make a contract with me?" "Of course you're Natsu's sister and I remember that he talks about you everytime when we were small and we'll be great working together" "haha thanks Lucy plus my real other half is in the key still this is just my normal strength." "Oooh wow" "if you want to call it just say I open thee gate of the princess dragon ,  Nala." "Ok, lets go and find Natsu" "ok" "wait you're not like the other celestial spirits Lucy has that uses her power to stay here and fight?" "Nope like I said I'm not the celestial spirit I'm the half". Then after that we went off to find Natsu-nii chan, hope he understands".

Natsu POV
I can't believe her!! Why didn't she tell me?? She kept that secret from me all our live we're been together lived together and we were born together. I'm so angry, but I missed her...maybe I should just let it go and b with her since she's back and have fun with everyone, then when I was about to get up when I heard shouting " Natsu!!!" "Natsu!!" "Natsu-nii channnn!!!!" "Nala, minna what are you guys doing?" "We want you and Nala to be like last time you guys are brothers and sisters anyways so we want you both to get along again. We all know what she did wasn't except-able but still she did want she had to do" "Lu-cy ok" "Yay" "since we're all ok now lets go back to the guild and Nala can  see everyone again" "Wait, I can't go back after what happened they'll all hate me and I'm not part of the family anymore"she sais with tears coming down her eyes. " hey its okay don't cry, your still part of Fairy Tail and your part of our family" "yea he's right and I treat my celestial spirits like my own family so don't worry you have lots of families" "their right Nala and we'll always be by your side never leaving you" "yea and Natsu can burn them, I can freeze them and Ezra can always scare and scold them" "ahaha ok, let's go than.Lucy can we walk together?" "SURE!!" I'm so happy that Lucy and Nala are getting along well and are going to be good friends. Guess I'll only get to spend time with her tomorrow, I wonder who's the other girl that knows her secret too.

Nala POV
I'm happy that Natsu-nii chan thinks of me as family again, I hope that I'll get to hang out with him tomorrow. I know that Lucy will be the best celestial wizard to stay with and be friends with . We walked to the front of the guild, when we were standing outside of the doors I could see the guild name and I could hear the loud noises from inside, huh the guild hasn't change abit i taught to myself. "Ready to go inside and see everyone else again?" Natsu-nii chan asked I looked at all of them before saying "Yeah", honestly I was scared and nervous of going in and seeing everyone again but I have to I can't be in the shadows anymore. When the  guild doors open everyone was looking at us and I felt like running away, all of their faces looked like they saw a ghost or they wouldn't believe  that I was standing there. The first one to come to us was Master "is that Nala, Natsu?" he asked Natsu-nii chan "it is gramps" he answered with he's signature grin then everyone started to shout and tears were running down their faces "WELCOME BACK NALA!!!!" everyone shouted "TADAIMA" I said with tea running down my face. After that we partied and some asked me to explain what happened so I told them they all were so glad that I was back, we partied until morning some of us didn't even bother going back home to sleep we fell asleep in the guild.

TIME SKIP: MORNING 

Nala POV

When I woke up I looked outside and it was in the  morning guess we all partied until late at night and a lot my head still hurt from last night. Well I guess that's what happens when your in Fairy Tail and party here. I looked around and saw everyone still sleeping, guess I should just let them sleep in still, then my eyes landed on Natsu-nii chan and Lucy awwww they look so CUTEEEEE TOGETHERRR !!!!! THEY WERE CUDDLING EACH OTHER IN THEIR SLEEP AAAAAAAAAAAHHHHHHHHHHHH!!!!!!!!!!!! this is the best thing i need to tell Mira and Lissanna once they wake up or they will see it for themselves if both of them don't wake up before Mira and Lissanna. Three of us thinks they really look good together, after that I decided to go out and get some fresh air, I went out of the guild doors quietly and looked at what's happening outside I saw that they have markets so I decided to walk around and see if i can find anything nice to buy. While walking around, I saw lots of nice things that I decided to buy by the time I got threw half way threw the market I already have a huge pile of things what can I say I like shopping and I haven't been for so long. Then while walking, I suddenly banged into someone when I looked up from the pile my eyes widen and the person's eyes widen too. "LAXUSSSS!!!" I heard three people scream and running to him from behide, I can't believe it. "La-Laxus??!!" "Na-Nala I taught you died when we we're out on that mission??" "I-uh well I'll have to tell you when we get back to the guild" " oh ok its nice to have you back and alive " "haha thank. Uh ano who are those people that are standing behide you and were running to you?"  "Laxus why were you walking so fast?"asked a guy with green hair. " huh who's that next to you?"said a guy with a head gear, dolls floating next to him and his touge sticking out. "Guys this is Nala Dragneel. We were in the same team before something happened"Laxus told them. "Nice to meet you all" I said with a smile and a small wave. "Laxus san why don't we go to a cafe and I can explain to you and we can chat" "sounds good". Then we walked to a cafe, Laxus and his new team helped me carry some stuffs and I bought somemore stuffs on the way to the cafe too, I felt a little guilty and its just in the morning.
When we reached the cafe I ordered a slice of chocolate cake and a hot chocolate drink. "So Nala, before you explain what happened let me introduce my new team is called  Raijinshuu" 'wow, I'm so happy that you got a new team but why did you leave your old team?" "Well after you "died" all of us went different ways and well yea" "ohh sorry" I said looking down sad that that happened after my death "but hey don't worry we can go on  a job together for old times with the team and just us." "That would be nice" "so the guy with the green hair is Freed Justine, the guy with the tongue sticking out is Bixslow and the woman with the glasses and green dress is Evergreen" "Nice to meet you Freed, Bixslow and Evergreen" "nice to meet you too Nala" they all said . "So mind explaining" "oh yea haha so" then I explained everything to him and when I finished he understood. When we finished talking it was in the afternoon so we decided to go back to the guild. When we were outside I heard Natsu-nii chan and Gray fighting like always. I sweat drop then walked in the guild with Laxus and his team. Once we entered  , they stopped fighting and I saw Erza standing near them and giving them stares haha no wonder I thought to myself.  After that I went to the bar where Mira was and asked for a chocolate milkshake and then I saw Lucy and started talking to her about jobs and life. 

Natsu POV

I woke up on the morning with Luce on my chest I saw our position and blushed ,then I slowly removed her and got up. I saw that Nala must have woke up early and went walking around,hope she didn't buy so many things. After that Luce and everyone else started waking up and we had a normal day at the guild. Luce went to the bar to talk to Levy and drinking strawberry milkshake. I then went and walked over to Luce and Nala "hey guys" "hi natsu" "hey natsu-nii chan" " Nala do you want to go on a job today or you just want to hang out at the guild?" "I don't mind going on a job Natsu-nii chan I kinda off need money since I bought stuffs at the market I couldn't help in all of the things are really nice'' "hahha ok I'll go pick one out" "Natsu make sure you don't pick a hard one and don't make your sister do the work ok?" "Huh Lucy your not going with us?" "No its ok Nala you and Natsu go and have a sister and brother time ok? " ok will be back soon." Then I walked to the job board to look at the jobs to pick for us,  nope this is too risky, nope this is too hard, ohh i found the right one. Then I took it to Nala and we told Mira that we'll be going on that job, then we told our friends then we'll be going. We had to take a train to Onibus Town to meet the client for the job, we had to take the train to go there and since both of us have dragon slayers magic we get motion sickness and Happy wasn't helping, he was sitting next to me eating fish while Nala was sitting opposite me. After what seems like forever, we have reach Onibus Town now we have to walk to the clients house, I just hope that we don't have to ride another transport.
