Fairy tail Natsu x OC x Gray Juvia's sister?!

Time

~Kaori's pov~

It's been 3 days since I've built my house and have come to magnolia. The house building took almost all my magic energy so I basically was asleep for 2 days recovering, yesterday I touched up all the little cracks and panels in the house so it is ready for all the furniture. Soon enough it will actually be liveable, I'm so excited.
I've been too nervous to go to fairy tail so I have been trying to not think of it. I'm so close to her but I'm so nervous I won't recognise her or she won't accept me. I bet she won't know me. I bet I'll scare her.
I sigh loudly and slump down on the floor.
"Thinking sucks"

~time skip~
It's been 9 days since I came to magnolia, I have fully regained my magic energy and am planning on going to the guild hall to join soon. I'm just so nervous.
"I suppose I should go to fairy tail soon" I say sighing. I can't believe I'm saying this so calmly. I sit up and stretch.
'Time to get dressed'
I put on my usual outfit and walk into the bathroom
"I'm coming Juvia"

I push open the door to my empty house and walk outside, shielding my eyes from the bright sun.
"What a beautiful day..." I say to myself.
I walk moderately quickly to the fairy tail hall, keeping my head up the whole way. There are so many beautiful smells in this place, it's gorgeous. I'm so glad she chose to live here.
"You would love it here Taliah, I just know you would." I think to myself.
After looking at all the brightly coloured stalls and beautiful smelling flowers and cakes, I stopped abruptly accidentally running into the back of someone.
I gasp and step back.
"I-I I'm so sorry!" I stutter. I look up and see blue eyes looking down at me. She looks familiar...
"Don't be sorry, it was Juvia's fault." The girl says waving her hands in front of her face. I gasp and feel my heart stop.
'Juvia'
She reaches a hand down to me, helping me up. I take a deep breath and accept her hand. She pulls me off the ground and I dust myself off.
"Thank you, I'm sorry but I have to go. Have a good day!" I say and run off in the opposite direction.
"Ohmygodohmygodohmygodohmygodohmygod" I mentally scream. I run until I reach a little cafe, I quickly open the door and walk over to a stool.
"I saw her. She saw me. It was her. Her. JUVIA!!!" I mentally scream, staring at a wall. I bet I look crazy right now but I don't give a single damn.

After mentally screaming for 20 minutes I stand up and walk outside again.
"Now I know who she is, it shouldn't be that bad should it?" I ask myself.
"Time to join." I say determinedly. I turn and start walking towards the guild hall once again.
After I finally get there I walk up the stairs and stare at the door.
"Oh god" I sigh then slowly push the door open.
I walk through the doors, my hair plated loosely down my back with my bangs hanging out. My black and white converse match my black painted nails. I'm wearing a floral crop top and grey/white ripped skinny jeans. I hear people whispering about me.
Luckily I'm a dragon slayer so I can hear everything they are saying clearly. Thank goodness it's all good things about me, most of the things being said are just people asking who I am or why I'm here but I hear a few people saying I'm pretty. I look around and see Juvia staring straight at me smiling. I smile back and start walking towards what I presume to be the master. I hear a bunch of wolf whistles and cat calls but I ignore them and walk straight up the the man.
"Excuse me sir?" I ask softly
"What would you like child?" He asks back
Aww he's so small!
"I would like to join your guild" I say acting as confident as I could.
He looks me up and down, stands up and twirls me, gets on the ground and circles me, smells me then gets back on the bar.
"Of coarse you can my dear, I can sense that you have magic energy but I'm not fully sure what it is yet, mind telling me?" He asks curiously.
I mentally scream and have a mini mental dance party.
All eyes are on me curiously. I feel like turning and looking but I know better.
"I-I'm an elemental mage" I say slowly, trying not to scream in joy.
Another chorus of whispers and I smile sweetly at the master.
"My name is Makarov, I am the master of is guild, what is your name?" He asks kindly.
"Nice to meet you sir, my name is Kaori Lo-" I cut myself off.
"Kaori" I say again. He smiles and waves a girl over. She's so beautiful!
"Hello! My name is Mirajane, but you can call me Mira." She says smiling.
"So pretty..." I say out loud. I instantly realise what I said and smack my hand over my face. She starts giggling
"Thank you" she says. I sheepishly smile back.
"Where would you like your guild mark?" Mira asks.
I look up questioningly. Where do I want it?
I look down at my stomach and smile, I basically wear this every day apart from in winter so I guess there.
"On my stomach please." I say pointing to the bottom left corner of my stomach.
"Okay, what colour?" She asks smiling
'Crappppppppp, I don't know?!'
I look around and see some of the colours other members have and start thinking.
Hmmmm, maybe...
Nobody else seems to have purple that I can see... I do love the colour purple.
"Purple please" I say smiling.
Mira picks up a stamp and gently places it above my stomach and presses down.
"Congratulations, your officially the newest member of fairy tail!" Mira says smiling. Suddenly the room erupts with cheers, I look around and see everyone cheering and clapping.
I made the right decision.
