Erza's pov.

Koori told us about her, I mean who she really is. We've decided to keep it a secret in Team Natsu. We will tell the guild later as it will be hard for them to accept her but she requested me to tell Gramps about this as she couldn't bring herself to tell him.

"Gramps, what are you going to do with her? Are you keeping her in the guild?" I asked the master of Fairy Tail.

"Hmm. I would like to keep her but what about the other members?" Makarov said while massaging his temples.

"But we all know she's a good person. She wouldn't do any harm to us."

"Let's keep that for later. Erza, the grand magic game is coming up. We need to prepare for that. And about Koori...she won't be participating in the game since she's not the mage. She'll act as a trainer to the group."

"Who are they?" I asked with curiosity.

"I'm going to announce that to the while guild. Come." Master said and led me to the stage.

"Ahem. Attention please!" Master shouted and everyone turned around to us.

"What is it, Gramps?" Gray asked.

"Listen, everyone. The grand magic game is coming up. As you all know, our guild is currently ranked the last because of the disappearance of our core members seven years ago on the Tenrou Island. So we need to gain our title back as Fiore's number one. And I've chosen who will be participating in the games. Natsu, Lucy, Gray, Erza and Wendy, you will be in the games representing Fairy Tail. Elfman will be the reserve member. So please do your best. We have three months for training. Mira, Laxus, Juvia, Mystogan, Gajeel, please come to my office." Master said and left the stage heading to his office with the said people following him.

'Mystogan...the most mysterious member of our guild but he seems familiar. Who is he really? I know he is an S-class mage and has a really strong sleeping spell but what is his true magic?' I shrugged it off and went to make a plan with Team Natsu plus Koori.

"Erza, do you have any places in mind for the training?" Koori asked me.

"Not yet. What about you?"

"I have found a mountain in the north side of Magnolia. It is quiet and the weather is also nice. It is quite spacious and suitable for training. Plus, people don't usually pass by." She said and I nodded as an agreement.

"Let's go pack our things. Well set off tomorrow morning at 9 a.m." I said and we went back to our respective houses.

Koori's pov.

I'm going to help them in their training. It's been a long time I've practiced though. I have to admit that I miss my brother a lot. He must be worried about me. What should I do? I can't even open a gargenta here. I don't know why. I think I'm going to be stuck in this world forever. I went back to Lucy's house where I'm currently staying at. Lucy and I packed our things and sat down on the sofa.

"Lucy, how is it like to be a human?" I asked her which startled her a bit.

"It's good I think so. I don't know how to explain it." She said and chuckled nervously. "What about you? How is it like to be an arrancar?"

I thought for a while and sighed. "It's not actually good. We are nothing but tools for our Lord to achieve his goal. He wanted to become a God and all we have to do is to listen to his every order. But I don't feel lonely thanks to my brother and my best friend. They were always there for me when I needed them. I was once human before I became a hollow but I don't remember a single thing except from my brother." I finished and looked down at the ground.

Lucy put a hand on my shoulder. "Hey. Don't be so sad. We're here for you. Fairy Tail is your family." I couldn't help but smiled.

"Thank you, Lucy. I feel much better now." I took her hand from my shoulder and held it in my hands. "Why don't we rest for the night? I'm going to put all of you into one hell of a training tomorrow. Don't expect it to be easy. Good night, Lucy." I said and headed to my bedroom.

"Good night, Koori." She said and I saw her went into her bedroom.

Tomorrow would be a big day.
