So... Lucy and Yukino wanted to do something for the celestial spirits for their hard work so here we are.
"All the Zodiac celestial Spirits worked so hard for us the other day."-Yukino
"Yeah! I heard you guys were really awesome!"-Natsu
"They managed to shut the Eclipse Gate!"-Happy
"Your welcome. I'm sorry."-Aries. You sweat dropped as she apologized again.
"So, we thought we'd show our gratitude by showing you all a nice time here on Star Hill!"
Aries was about to say something but Lucy cut her off, "So, theres stuff you've always wanted to do, right?"
"Just tell us what your wish is and we'll make it a reality."-Yukino
Aries started shaking a bit, "I-I want to get a tan!" You blinked a few times. "I-I'm Sorry..."
"A tan...?"-Lucy
"I'm always fluffy and wooly, but I'd like to get a nice golden brown—."-Aries
"Oh! Just leave that to me! Fire Dragon Roar!" You freaked out, "Natsu!"
You gasped at what you saw after. "Th-this it! It's wonderful! I'm sorry!"
"Whoa, no way. She actually got what she wanted..."-Lucy
"That's a celestial spirit for ya!"-Natsu.
"I'm so happy! I'm sorry!"
"I-I'm glad, then... See you later!"-Lucy
"Yes, I look forward to it! I'm sorry!"-Aries
"Oh, well. Next one!"

Time skip
Happy suffered many spirits. Natsu got punched by Leo two times. Libra hates everyone. Virgo got flicked by Lucy. Capricorn is a cheesy poet. Taurus is a perv. Cancer gave Happy an Afro. Sagittarius has bad aim and ended up messing up Cancer's work. You fell asleep when Scorpio came. Gemini embarrassed Lucy. Pisces hates cats and nearly ate Happy. Aquarius has a heart deep inside.

"Hah? These clouds just randomly came... and it's not gonna rain, is it?" You stood up and looked up.
You were currently on Fairy Tail's roof. Everyone was currently on a job except for Lucy, Natsu, Happy and a few others.
It started raining... "Are you kidding me?!" Groaning, you jumped down and walked in the guild... soaked.
"Stupid rain..." "Oh my! Madam Y/n!" 'Madam...?' You smiled and waved. "Hey, Y/n! We're going on a mission, wanna come?" "Wha?! We don't need another person!" You frowned as Natsu said that.
Ever since the GMG's, he's been trying to avoid you. "Thanks, Lucy. But I'll be fine. It looks like I'm not wanted. I'm... taking my leave now..." You sadly smiled and walked back out the guild.
"Really, Natsu?! You might've hurt her feelings!"-Lucy
"But.. I really wanted N/n to come.."-Happy
"Why would you say that..? I thought you two were like partners. Almost like Bisca and Alzack."-Mira
You scoffed and continued walking in the rain.
'I guess visiting Zeref and Bell wouldn't hurt.' You smiled and teleported to Zeref. You felt a sharp pain through your stomach but ignored it.
"Hey. Sorry I haven't visited in a while." They turned to you. Bell glared as Zeref looked away. "Are you oka-?" "Cheater!" You flinched and looked at Bell. "You cheated on Papa with uncle Natsu! You hurt his feelings!"
You made a confused face, "Cheated...? What did I do to cheat?" "Bell told me you slept with him during the GMG's..." You flinched again at how sad Zeref sounded.
"But-." "Just leave... Please..." You froze and stared at him.
"Leave, mom! He doesn't want you here!"
Your eyes started to tear up as Bell shouted at you. "We don't need you... We were fine with you gone..." Tears slid down your cheeks. But you cracked a smile. "Heh..." Bell and Zeref looked at you confused.
"I guess I'm not needed today at all... Take care." With that, you teleported away from them.

Present
You were crying at your favorite place... the bridge.
"N/n?" You flinched and turned to see Happy, Lucy, and Natsu coming towards you.
"H-hey." You wiped your tears and looked at the water, avoiding their gaze.
"What's wrong?" Lucy's voice was heard. You made a close-eyed smile and faced them.
"Nothing! I'm fine. Why aren't you at your mission?" You turned back to look at the water, avoiding their gaze again.
"We were about to go but Happy saw you and here we are. Are you sure you're okay? You're normally here when your sad." You tensed as Lucy touched your back but you kept your gaze looking at the water.
A tear slid down your cheek. "N/n?!" "Y/n?!" Happy flew to you as Natsu ran to you but stopped before he touched you.
"I guess today isn't my day... Lucy... Bell doesn't want me near her... She's staying with the guy she thinks is her dad... I'm sorry... I shouldn't be crying."

"But you should. That's your daughter."

"... Not actually my daughter but whatever..."

Lucy began to rub your back in a soothing manner as you stared at your reflection, "I guess Fairy Tail really does change a person... Don't you ever wish you could become the person you once were..? Maybe not you guys but probably for me..."

Arms wrapped around you as small paws lifted your head. "Maybe you should take a break... As long as you need, try to become the person you once were."

"That's going to take another lifetime. I'll just try to keep my mind occupied with missions and stuff. I won't have time to visit Bell or hang out with people that will end up leaving me. Good luck on your mission."

Once again, you teleported. This time, inside of Fairy Tail.

"Hey, Mira! Is there a mission that I could do?"

"Mhm! This one requests for a dragon slayer! They need you to defeat a evil mage who has been stealing and killing the townspeople. No other magic can defeat him. They don't have a dragon slayer which explains why they need one."

"I'll take it. How long will it take?"

"About a month. They say he randomly comes to the town so they don't know when to prepare for him."

"Okay! See ya in a while, Mira!"

At The Town

"You must be the Fairy Tail wizard! Thank goodness you came! That evil person just attacked yesterday, killing about 5 of our people," the elder of the town frowned sadly.

"Don't worry, sir, I'll make sure to help the town. Do you have any information on this person?"

"He is male, and has dragon slaying magic. Our mages in the town say it's Dark Dragon Slaying magic which is very deadly and powerful. I assume you're a dragon slayer as well."

"Yes. I hold all magic but mainly use Ice Make and Dragon Slaying magic. Is that all you know?"

"Yes. We have a place for you to stay in the mean time. Follow me," he began walking away, you following closely behind.

The elder had given you a small, comfy place. Practically a two story house with a balcony that you've been at the whole day.

Nothing happened yet...

Two Weeks Later

Currently on the balcony, enjoying a (favorite flavor) cupcake, you hear a loud BOOM!

"He's back!"

"Where is the Fairy Tail member?!"

Putting the cupcake down, you jumped onto the roof and looked around. You see smoke in one area, so you run to the direction. There, you see people running away from the area while a few mages stayed behind, attempting to fight the male.

"Ice Make: Lance!"

You jump in front of the attack and shield yourself and the male behind you.

"What was that for?!"

"The heck!"

"Don't tell me she's his partner!"

Giving a sigh, you narrowed your eyes at the males, "I'm the Fairy Tail mage."

"A girl as a dragon slayer?! Ha! I don't believe it!"

That hit your nerve, "I'll let this guy destroy you if you don't run in 3 seconds."

1...

2...

3...

"F*ck it, Ice Make: Cage."

The guys were now caged in ice that was colder than regular ice.

"I don't believe your a dragon slayer, either."

Finally, you turned to the male you were supposed to fight. "Bring it on and I'll show you that I am."

"Roar of the Dark Dragon!"

His attack came flying towards you but you easily dodged, "Celestial Dragon Roar!"

The attack hit him, making him stumble back. "Oh, it's on."

After The Fight Because I Cant Write Fight Scenes

"Let us put him behind bars!"

"Give him what he deserves!"

"Why are you defending him?!"

Sighing, you continued to drag the knocked out male, "I'm taking him away forever cuz he can break out of your cage. Plus, I have a feeling I could change him. Your welcome for helping but I'll take my leave now."

With that, you teleported to a nearby river. 'I can't rely on my magic that much. I'll heal him and myself the regular human way.'

Time skip again 0w0

It's been 2 days at the guy hasn't woken up... you went a bit too rough on him...

"Ngh..."

Turning your attention on him, you stayed a safe distance away. His eyes opened and he sat up, "Where am i..?"

"Somewhere far from people who wanted to kill you while you were knocked out."

He looked at you with a blank face, "You're that girl that beat the crap out of me..."

"Yep. Sorry for being too harsh. Why did you attack the town?"

He kept quiet for a moment, "I don't really know. That village had always disliked me, even as a kid. There was only one person that liked me but they took the person away from me. I guess I just had nothing to do and took my anger out on them."

You started thinking, 'Maybe he can be my partner for missions... I will be going to difficult missions often so it would be nice to have someone with me. He doesn't have anything to do so... I'll ask.'

"Hey. You wanna be my partner for missions? I'm trying to keep myself preoccupied so I don't have to deal with drama at the guild. I'll be going on missions all the time so would you like to tag along with me?"

He looked at you as if you were crazy, "You literally just knocked me out and I'm a bad person... yet you ask me to be your partner?! I was trained by Acnologia!"

"And I was trained by mostly every dragon so what's your answer."

Sighing, he nods, "Sure. I'm Niko by the way."

Smiling like a dork, you fell back so you were laying down.

"Oh, who was that person that they took from you?"

He stayed quiet before sighing, "My best friend since birth. The girl I fell in love with until she was framed of a crime she didn't commit."

"Where is she now?"

"They trapped her somewhere. Island of Curses. I don't know where it is but hopefully I'm able to find it while going on missions on you."

Your eyes lit up and you sat up, "I heard of an S-Class mission involving Island of Curses! We could go now!"

This time, he quickly appeared in front of you and pulled you up, "Let's go!"

I'm seeing what I can do without the series for now. Hopefully it all goes well and we'll see how your relationships with Natsu, Belle, and Zeref go. Btw, Niko is my best friend. That's a story for another time tho... Hoped you enjoyed!
