Gate Holder of the Celtic Zodiac Keys, and also Natsu's younger sister?

Chapter 15: Hall of Thunder, also known as the Thunder Palace.

3rd Person Pov.

Yuki was sitting at a table, Clenching and unclenching her fists, and none of them dared get near her. As all of the girls turned to normal from Stone, Happy hugged Lucy happily,and Master said how the hostages were free but Yuki just looked over out of the corner of her eyes, not moving from her spot. Master explained what had been happening to them but Yuki was tightening her hand into a fist as everyone talked. Natsu then stood up for Laxus by saying he liked the idea of finding out who was strongest, and he told Master not to be too Harsh on Laxus.

"So Yeah, Let's start the battle of Fairytail, round 2! All of you bring it on!" Natsu yelled but Yuki jumped off of the chair she was in and she landed on Natsu's back making him fall to the ground and she stood on his back.

"I win." Yuki said making the others all laugh slightly but Master, Juvia, and Gajeel.

"Yuki, you are suffocating him." Happy said making Yuki look at him then she stepped off of her pink haired brother. Yuki looked down seeing she was still in her pink top, pink miniskirt, with boots and long socks plus the band on her arm showing the Fairytail mark.

"wait I haven't done anything." Natsu said then Lucy said how she didn't know if he was joking or not because it was Natsu.

"Natsu, I don't think you should go picking battles with girls." Happy said raising his paw from behind Natsu making Yuki tilt her head.

"Girls or guys has nothing to do with it." Natsu said with a look on his face, that made Yuki think of a disgusted look and she got slightly mad.

"Whoa, he looks pissed off there!" Happy said angrily but Yuki wrapped her arm around her brothers shoulder.

"Snatched!" Yuki said grabbing his scarf and she ran away with a giggle wrapping it around her neck. She then while he was trying to catch her, got his vest and put it on. "Hey everyone! Look at me! I'm Natsu! I'm stupid and a big jerk! ROOOOOOAR!" Yuki said doing her impression, stomping her feet around on a table she was standing on. Natsu then started to run after Yuki, and Yuki ran over to Lucy so Natsu was chasing Lucy and Yuki. Then the runes started to act up, a skull of the runes appearing in the room. It talked with Laxus's voice and Yuki payed attention as the others did also. Hall of Thunder? Master got angry then he passed out in pain. Mira said he needed his medicine as everyone got worried but then Yuki's eyes widened and she looked at her hands. Yuki ran over to him and she put her hands out closing her eyes tightly as stars escaped from her hands surrounding master, as her dragon slayer magic appeared and she started to try and heal him.

"Yuki?" Lucy asked worriedly seeing Yuki flinch, her face turning slightly pale as she used more and more of her magic trying to find what was wrong and trying to heal him as best she could.

"Y-Yuki." Gramps muttered Mira came back with his medicine telling everyone to go outside to look but Yuki kept trying to heal him as Mira came over.

"Yuki..." Mira muttered and Yuki stopped breathing hard and she almost fell forward. "I can give him his medicine and lay him down. Go join the others on the roof." Mira said making Yuki nod then she walked up to the roof. As Yuki got to the roof she saw Bisca shoot one of the lacrima's then as she got fully to the roof she started to get shocked and she screamed in pain.

"Bisca!" Yuki yelled running forward as she screamed in pain, then she fell to the ground.

"Hey, Hang in there, Bisca!" Natsu said as Levy also ran forward sitting her up but Yuki put her hands out with out second thought and stars appeared from her hands as she started to heal her, the shock marks disappearing from her but she stayed passed out.

"She should be out for a bit, but I healed most of her." Yuki said but then her eyes widen, her pupils getting smaller and she almost fell forward.

"H-Hey!" Natsu said jumping to catch his sister as she almost passed out.

"She using to much magic by healing." Lucy said walking over to Yuki and Natsu. "Remember she said something like that, healing takes up more of her magic than anything." Lucy added worriedly but Yuki looked up.

"I'm getting better at it, and only way to train yourself to get better is by doing the same thing over and over again." Yuki said slowly standing up and leaning on the railing as Natsu jumped over it trying to get free. Then all the girls left except for Yuki and Levy, since Yuki, Natsu, and Gajeel all couldn't leave and Bisca was still passed out. Levy then said she could try and break it but Yuki picked up Bisca and carried her to the infirmary where Master and Mira were. Yuki laid her down then looked at Master once more seeing him flinching in pain in his sleep.

"I'll try to help." Yuki muttered walking towards him and trying to give him a pain reliever type of healing. Yuki walked out and saw on the runes that Lucy was fighting Bickslow, well shit. Yuki didn't know much about them, being a newbie and all, but she thought he used puppets if she remembered hearing right.
(Me: *Squeals as Loke saves Lucy from Bickslow.*
Yuki: I thought this was my story?
Me: Fiiiiiiine~ Continue with the lovebirds fighting.
Lucy&Yuki: They/We aren't love birds!!!Happy: Yeah~ Lucy liiiikes Natsu~ Loke likes Aries.)

Lucy won against Bickslow making Natsu and Gajeel start to yell at each other, then Levy yelled that she got it scaring the guys, but then she found out how to break the runes.

"Just wait here, I am going to overwrite the runes!" Levy said, then asked if Natsu and Gajeel were ready to join in but Yuki walked forward next to them from where she had been sitting.

"Yeah." Yuki said, but she had no intention of fighting right away, or maybe not at all, she knew she was hurting because of how much magic she had used on Master and Bisca, then when she tried to summon Cho Cho, the whole time she was frozen in stone she was trying to summon her so she had been wasting magic the whole time until she was unfrozen. As Levy was working with the runes Yuki saw that Cana and Juvia were fighting, then after a few seconds, Cana won, that was too quick.... Juvia must've.... Yuki thought about what could of happened but then as Cana and Fried fought, Cana lost. Mira and Freed started to fight as Levy sent Yuki, Gajeel, and Natsu off, but Yuki just took off running.

"Yuki! Don't get hurt!" Natsu yelled after her but Yuki ran right into town, following her nose as she ran getting scared.

"Gray! Arashi!" Yuki yelled running into town following her nose, running past people who were confused on what was happening but she didn't care. Passing some of her comrades on the ground she felt bad but kept going, she felt like something was wrong. Yuki needed to find Gray and Arashi.

(Sorry it's short.)
