Erza knightwalker was walking through a long stone hallway. She had been given the title first commander over the Royal Army. She was wondering why but she assumed that it was mainly because Pantherlily wasn't with them in their world. Erza just walked on by herself but then she stopped when she remembered the reason she became a member of the Royal Army. It wasn't her goal in the first place, in fact it was because she was taken from an orphanage that her parents had left her in before she was even 8 years old.

Just the thought of her childhood angered her but she had to keep calm since she couldn't walk around in a bad mood like she had been when it was King Faust. When he was king he allowed her to walk around in anger and even allowed her to freely kill many magical guilds.

Now here she was, a higher ranked leader of the Royal Army that would just carry a blank expression on her face.

As she was walking through the stone hallway she stopped when she heard her name being called. It was Hughes. He wore his playful smirk that he always carried and he seemed to have something to tell her.

"What have you been up to, Erza? You look like you're dead or something."

Erza looked away.

"It's nothing, I'm still getting used being in a different rank."

"Same here. King Mystogan told me and Sugarboy that he will only have three captains instead of four."

Erza didn't say anything but nodded.

She went to her bedroom and just laid on her bed. She was in too much deep thought of being in a higher rank which meant more stress for her. She closed her eyes then drifted off into sleep.

Dream

12 year old Erza was sitting alone in front of a river. She had a few rocks with her and had began to skip them. Every rock she had tossed had skipped to the other side.

"I don't get it. What did I do that was so wrong to my parents? I did everything they said and they still left me here in this place. None of the adults here care about us, all they do is collect us, they get their money and neglect us."

She skipped another rock that made it on the other side of the river.

"I wish I was more than a rock that could be tossed around."

She looked up at the sky and saw a bird.

"A bird maybe, so I can fly away to be happy."

Dream End

Erza woke up only to see that it was morning. She took a shower and got ready for the day.

When she was done she had left to train with her soldiers who had no complaints of her being their leader. While she was training with them a soldier came running to her.

"Captain Knightwalker, the King requests for you to meet him right now."

Erza gave a nod then had her soldiers to go back to their training then she left to the throne room.

When she got there she saw Mystogan sitting in the throne chair and he was looking at her. She kneeled and spoke.

"You called for me, my King?"

"Yes, I want you to look after someone until they get their memory back."

Erza blinked then looked up and Mystogan called out.

"Alright child, you can come out now."

Erza looked to see a 13 year old girl come from behind Mystogan. Erza's eyes widen in shock as she got to her feet looking at the child that was looking back at her.

The little girl had cream tone skin and green eyes. She had glossy black hair that hung to her shoulders, framing her face. She wore a blue short sleeve dress shirt that hung to her thighs and slits on the sides. Under the dress, she wore black tight shorts and she wore blue shoes.

Erza's shock expression remained on her face as she looked at the child that was looking at her. Mystogan thought it was because he was having Erza to watch after the child but then Erza spoke.

"Minerva."

Mystogan looked at Erza.

"Do you know her, Captain Erza?"

Erza blinked realizing that she had been staring at the child then she looked at Mystogan with a blank expression.

"Yes, your Highness. I do know who she is."

"Alright then, it should be easier for you to look after her then."

Erza nodded then looked at Minerva.

"Come Minerva, let's go."

The scared child looked at her.

"Who are you?"

Something inside of Erza shattered but she didn't show it.

"I'm Captain Erza Knightwalker, come."

Minerva shyly went to Erza then they both left out of there. As they were walking through the stone hallway, Erza looked ahead with a thought on her mind.

'Does she not remember me?'

Erza looked over her shoulder at Minerva who was following her but had her head down. Erza wanted to know so she stopped and so did Minerva who looked up at her.

"Is something wrong, Ms. Erza?"

Erza turned to face her.

"Minerva, do you remember anything at all from your childhood?"

Minerva lowered her head.

"Well not that much. All I remember was living in an orphanage with a lot of other kids but they were all mean to me, except for one."

Erza just looked at her as Minerva went on.

"You kind of do look like her. She was one of the few older kids that was there and she was the only one who was nice to me, so I began to call her my big sister."

"And now what are you trying to do?"

Minerva poked her fingers together shyly.

"I'm looking for her."

Erza looked at the little girl then she rubbed the girl's head.

"I hope that some day, you will find your older sister."

Minerva looked up at her then shyly smiled.

"Thank you."

They went on walking through the hallway to go somewhere else.

For the whole day Minerva was with Erza who was mentally fighting a battle not to scare the little girl since so much has been going on. It was about 5 months ago since they had lost magic and Erza Knightwalker couldn't but think about what her counterpart, Erza Scarlet had told her when they last fought.

She remembered how Scarlet explained what a real leader did for their people, to help encourage them to be better and protect them. When Scarlet was telling her that Knightwalker had flashbacks of her childhood of how she was in the orphanage. It wasn't because she felt neglected and wanted to hurt everyone who done wrong by her. All she was really doing was protecting the one who somehow felt a good bond with.

And the person she had built a firm bond with was Minerva, but somehow Minerva doesn't remember her and Erza is mentally fighting the hurtful feeling from her.

When it was night time Erza wondered what she should do. There was only one bed in her room, a queen size but she doubted that Minerva would sleep next to her since they had just met. She figured that it would be a bother to ask Coco so she brushed that idea off.

When they arrived to Erza's chambers, Erza looked at Minerva.

"Alright, you will be sleeping in here."

Erza turned to leave the room but stopped when she felt a small hand grab her wrist. She looked back to see Minerva looking up at her scared.

"Is something wrong?"

"Where are you going to sleep?"

"I'm just going to sleep somewhere else."

"No! I don't want to sleep alone."

Erza just looked at her then she nodded.

"Alright then, Minerva I'll stay with you but tomorrow I will have another bed put in here."

"One bed is fine, I just don't want to sleep alone."

Erza's brow widened but she didn't say anything.

The two girl both got ready for bed. Erza laid on her back on the bed and Minerva was sleeping facing her. Erza thought that Minerva looked adorable that really wanted to bring the child into an embrace and kiss her fore head. She just couldn't once again, she was afraid of more discomforting feelings that were rising.

She closed her eyes to sleep but opened them when she felt Minerva snuggling up to her, resting her head on her shoulder. Erza just stared at her then she smiled.

"Goodnight Minerva."

With that, Erza was asleep.

AN: Well there is Chapter 1 to A sister and a Knight. I hope that it was a good chapter, let me know how I did and I will update. Bye!
