About two months had passed since the Grand Magic Games. Everything was peaceful back in the guild and Mercedes had became a member of Fairy Tail. During her time there she really loved it. She was like a little duckling for Erza because from time to time she would follow Erza around the guild. Erza didn't mind she thought it was cute and would hug Mercedes who would cling onto her. Even Mirajane would glomp Mercedes whenever Mercedes would just copy Erza and would ask for a cheesecake.

One day Mercedes was looking at the jobs on the S class job board. She had been on a mission before but the first one wasn't an S class. She did ask Erza but the first time Erza told her no since it was her first time and she should go on an easy one then maybe she could go on another job that would be an S class. Erza told her that every time she goes on any S class jobs she has to either ask her or Mira. At first Natsu told Erza that she was being overly protective but Mercedes told him that she was thankful for it.

As she stood at the S class job board she saw a job in a place that was in the Sun Village. She saw that it was located in the land of Deserta. She got the paper and went to the bar area only to see that Mira was there. Mira smiled at Mercedes who was looking up at her.

"Hi Ms. Mira."

"Hello Mercedes."

"Do you know where big sister Erza is?"

"I think she went out to get something. What job are you going to go on?"

Mercedes handed Mirajane the paper.

"It's an S class job in the Sun Village in the land of Deserta."

Mira saw that the job shouldn't be too bad. The village was recently turned to ice and any S class wizard that could use fire would be able to do the job.

"Alright then good luck on the mission. I will let Erza know when she gets back."

"Okay thank you."

Mercedes left on her mission to the Sun Village.

When Erza returned to the guild she was holding cheesecake and was looking for Mercedes. She went over to Mira who was at the bar area.

"Mira have you seen Mercedes anywhere?"

"Yes. She went on a job request."

"Where to?"

"She went on an S class job to the Sun Village in Deserta. Just recently it was frozen solid so she went on it."

Erza was in shock then turned to leave.

"I'm going after her."

"What for?"

"I don't why but I have a bad feeling that might happen to her."

Erza ran out of the guild. She was followed by Natsu, Lucy, Gray, Wendy and their Exceeds.

'Please be safe, Mercedes.'

With Mercedes

Mercedes had arrived to the Sun Village and was in shock to see the whole village frozen solid. She ran closer then walked around the village. She felt so tiny because also frozen in the village were giants. Mercedes blinked then looked around more to find a way to somehow put the village back to normal.

"What happened here?"

She kept running though the frozen land then stopped. Mercedes got out her fans then opened them both up.

"Time: Firebird!"

A large bird that was coated in flames flew through the village but there was no sign of melted ice anywhere so Mercedes did it again.

With Team Natsu

They were in the forest that was coming closer to the Sun Village but then they stopped when Happy spotted two large fire birds in a distance. Erza instantly knew where the fire birds were coming from so she ran on ahead of her team.

'Just wait there for me, Mercedes.'

Elsewhere

Two people a man and a young woman were both walking and they both saw the two fire birds. The man grunted.

"It would appear that some wizards 'on the surface' have abnormal magic like we do."

His partner smiled at the sight.

"Yes there are. I didn't expect to have a visit like this on this mission."

'I see that you have improved, Mercedes.'

The man walked on ahead.

"We still have to destroy the Sun Village, let's go newbie."

The woman smiled at him.

"Newbie? You will address me as Lady."

Back in the Sun Village.

Mercedes frowned at the fact that she couldn't make a difference.

"One would think that this mission would be easy. What do I have to do to get this village back to how it was?"

Mercedes went over to feel the ice. True it was cold but for some reason to her it was warm.

"What kind of ice is this?"

Not soon after she touched it the ice was hot and she pulled her hand off of it.

"Dry ice? But how?"

She went to another part of the village but then to her shock while walking she saw Erza running towards her.

"Mercedes!"

Mercedes ran to her.

"Big sister!"

When they got to each other Erza hugged Mercedes tightly in her arms. She held Mercedes as if her life depended on it.

"You scared me."

"I'm sorry."

"It's okay, as long as you're alright."

Erza let her go then looked at the village.

"So everything has been frozen. We were told that we had to look for the Atlas the Eternal Flame in order to put the village back to normal."

"How do we find it?"

"That's the problem, we don't know."

They began to walk on then Mercedes looked at Erza in complete shock when she heard a change in voice. She saw that Erza had been turned into a child. Mercedes guess Erza was changed to the age 10 at least then she went to Erza who just stared at her in confusion.

"Mecerdes, how did you get so big?"

"I didn't, you got short."

Erza saw that it was true. All that was covering her child body was her black shirt that she was still wearing. She looked at her clothes that were on the ground.

"Well this is embarrassing."

"Yep."

Just then Erza was being sucked into a ball of magic. Mercedes did grab her wrist to pull her back but Erza being a kid again slipped out of her grasp and was gone.

"Erza!"

Elsewhere

Erza soon found herself somewhere new. She tried to use her magic but only got a sword out.

"It took longer and took more magic."

"Not the best state for Erza to be in right?"

Erza looked behind her to see Minerva coming to her smiling.

"Minerva?!"

Minerva giggled then looked at Erza.

"So if I'm not mistaken, my little sister is here with you right?"

"..."

"Just answer my question and I'll let you go."

"Yes she's here but I don't know where."

"So she joined your guild. I know that Sting became the guild master of Sabertooth but why isn't she there?"

Erza frowned at Minerva.

"She didn't want anything to do with Sabertooth after what happened at the Grand Magic Games."

Minerva placed her hands on her hips.

"Are you saying she chose to leave Sabertooth to go to your guild?"

"Yes but I didn't force her to."

Minerva frowned but then smiled.

"Is that so? You know Erza, before Mercedes met you she was doing just fine but then you guild came along and took her from me. She even avoided me even more after she heard about you."

"You got it all wrong, I didn't take her from you."

Minerva kicked Erza.

"You took my little sister from me!"

Erza was getting beat up even more by Minerva.

With Mercedes

Mercedes was running through the village looking for Erza but couldn't find her so then she got out one of her fans and opened it.

"Year: Dog."

A hound dog appeared and Mercedes had the hound to sniff Erza's skirt that she had. After the dog got the scent it ran off and Mercedes went after it.

'Lead me to Big Sister Erza.'

With Erza

Erza was on the ground then Minerva had her sword in her hand and had it pointed at Erza.

"I'm glad to get payback but I want to know a few things first."

Erza looked at her.

"Like what?"

"Why does my sister want you over me?"

"How would I know? I'm just being an older sister figure for her."

"How could you not know? My little sister was the only person I cared for in this world!"

"No offense but no one else sees that not even Mercedes. She even brought that up herself asking if you ever cared for her. Even on the night at the ball I asked why she looked depressed and she told me what she told you."

Minerva raised the sword.

"You have no idea how much that hurt me when my sister told me that night. Out of everything we have been through, my sister talking to me like that was more harmful than our father's words!"

Minerva brought the sword down but then a hound came and bit her arm stopping her in time for Erza to turn back to normal and kick Minerva twice. The hound vanished then Mercedes came to Erza and gave the skirt to the skirt. Minerva got up and faced them both.

Minerva wanted to frown but hid that with smile when she saw them together.

"You know Erza, you really should see a wardrobe stylist."

Mercedes just replied.

"Minerva we can say the same about you."

Minerva blinked then looked down when she saw that her skirt was missing and her underwear was showing then she looked at them to see that Erza had her skirt smiling at her. As Erza smiled at her Minerva had a death glare on her face while speaking in a different language.

{Why you...}

"Now relax, it wasn't on purpose."

Just then they all looked up when they saw that the giants had been turn back to normal and were looking back at them. Minerva had gotten her skirt back and was leaving. Mercedes looked at her called out.

"Minerva!"

Minerva stopped and looked back at her little sister while smiling at her. Erza looked at Minerva as well.

"Don't fall into the darkness!"

Minerva kept her smile on her face as she replied back at them.

"Oh please...it will be me controlling the world with darkness not the other way around! Until we meet again, you two!"

With that she was gone. Mercedes lowered her head then Erza went to her.

"Mercedes, is something wrong?"

"I'll tell you when we get back to the guild."

"Alright then."
