The next day at the guild Mirajane was outside walking with Elfman and Lisanna. They were having a small talk about whether they should stay and become Fairy Tail members of the guild or should they leave. Lisanna told her that she wanted to stay because it looked like fun. Elfman agreed with her as well and he said that he wanted to become a man that can protect his family. Mirajane was happy to hear that from her younger siblings then they headed back to the guild.

When they got there Mira had them to stay and surprisingly Cana came to them and asked if they wanted to play a game. Elfman and Lisanna agreed then Mira went to talk to Makarov alone in his office.

When she got there to talk to him Makarov looked at her.

"Is something wrong?"

"Sir, I was wondering. Will you allow my younger siblings and me to become members of the guild?"

"Really now? You want to stay here?"

Mira lowered her head, she was trying her best not to cry.

"Please..."

"Tell me everything that has happened recently to you three."

Mira nodded.

"Our parents were killed on a mission outside of this city. I was the first to find out but I couldn't bear to tell Elfman or Lisanna so I kept it from them. I wasn't how long I was going to keep it up so then I made up a story that I thought would distract them from asking me about our parents so I told them we were going to go on an adventure. After we set out on our own the council found us and took us to prison. It was the first time I have been afraid but I didn't let it get to me so on the third or fourth day there were hardly any guards so we broke out of there. We managed to get away then that's we met you."

After Mira told Makarov everything Makarov closed his eyes.

"And they still don't know what the real story is?"

"No sir."

"If you three were to become members here you would have to master your magic here and also you three would be the first set of siblings in the guild."

Mira looked up at him to see that Makarov was smiling at her.

"You, Elfman and Lisanna will be members of Fairy Tail, welcome aboard."

Mira felt tears streaming down her face then she hugged Makarov, well more like tackling him to the floor. Makarov patted her head and chuckled.

"It's okay, let it all out."

"Thank you so much, Master."

Later on that day they were members of Fairy Tail.

It had been a month and Mira would see Natsu and Gray fight each other. So far she had different ways of bonding with everyone. With Natsu she would bully him, Gray she would bully also because of his stripping problem. Cana, she didn't have any problem with they got off on a good start. The main person on her list of bonding was also the same person she hated the most, Erza.

Just the other week Mira caught Erza talking to Lisanna about something and Mira, being the older sister she was told Erza to back off. Erza turned around and told her that she was a poor excuse for not helping her little sister with her Take Over magic. They began to fight each other but Lisanna didn't get in the way because Natsu, Gray and Elfman were there and Elfman had her behind him.

Sadly for the past month Mira would silently cry herself to sleep because she still never told her younger siblings the truth and it was starting to hurt her mentally. Mira left the guild to be alone and take a walk.

Inside of the guild Erza was eating a piece of strawberry cake. After eating it she looked around, looking for Mira.

'Something isn't right, she would have been fighting with me now.'

Erza went around the guild but then she saw Elfman and Lisanna playing a card game with Cana.

"Elfman, Lisanna where's Mirajane?"

Elfman looked at her.

"I haven't seen her all day."

Lisanna thought about it.

"Mira said she was going to take a walk and be back later."

Erza nodded then she left the guild to look for Mira.

As she was out she went past the bridge then soon saw Mira sitting alone at the shore. Erza went down to Mira.

"There you are, I was wondering where you were."

Erza stopped in her tracks when she saw Mira look over her shoulder at her glaring.

"What do you want?"

Erza frowned.

"I just said I was looking for you."

Mira stood up but still had her back turned to Erza.

"I don't want to see anyone right now that's why I left the guild."

"You're depressed about something aren't you?"

Mira looked at her.

"You shouldn't just leave like that."

"I didn't ask for a lecture."

"You're so stubborn, I'm surprised Elfman and Lisanna can stand you. I mean, you look like a gothic hooker, and you always have that tough act. If I had an older sibling like you I'd be staying away."

The next thing Erza knew she was kicked away a few feet then she tackled to the ground. She looked up, to her surprise Mira had tears streaming down her face.

"Don't ever talk about my siblings like that! You don't know what we've been through!"

Erza and Mira began to wrestle each other but Erza managed to pin Mira down.

"Alright I'm sorry, I didn't know how you really felt. I'm just kind of jealous."

"You? Jealous of me?"

"Yes, you came here and became members along with siblings and you still took the stand to defend them no matter what happened. You're stronger than me when it comes to things related to family."

Mira relaxed and they both sat on the ground next to each other.

"...Erza?"

"Yes?"

"Did Master tell you what happened to me, Elfman and Lisanna?"

"Only the part where you three were arrested and how he found you three in the forest after that. He told me that you and I had a lot in common."

"Like what?"

"Our parents death, being arrested and then joining Fairy Tail."

"He's right, we do have a lot in common."

With that Mira stood up and put her hands on her hips while having a proud smile on her face looking at Erza who was just looking at her in question.

"Alright redhead, this talk between us will be the only time we call it even but from this day on you are my lifelong rival."

Erza stood up and smiled back.

"Really now? I accept you challenge of rivalry, Mirajane."

They both raced back to the guild but didn't say anything to anyone. From that day on Mirajane and Erza became rivals for life.

AN: There you have it, sorry for the wait everyone, I was having a hard time trying to think of how I was going to write this chapter and how Erza and Mira were going to be rivals. I hope this is okay for you. Leave a comment that may come in mind, and take care!
