First day of the school year, nurse's office, Fairy High

Natsu had just left the office and Juvia was alone with her thoughts. The blue-haired girl was contemplating her options now.

Option one, she continues pursuing Gray, which would probably end way worse than her confession today.

Option two, she would lay off the idea of finding love for a while. But that would make her feel alone, and she doesn't want that.

Option three, she tries to find love in someone else, and that someone had barged into her life today just like a knight in shining armor.

Before she could dwell deeper into her thoughts, the door opened and in walked Erza. The redhead looked at her for a few moments. Then she turned around, closed the door, and locked it.

Erza then walked to the bed Juvia was currently sitting at and sat down next to her.

With a sigh, she said, "Has the nurse already checked you?"

Juvia nodded, "Yes Erza-neesama. Ophiuchus-sensei gave me some salve that reduced the reddening and the pain. She said it's nothing too serious"

Erza smiled softly and engulfed the other girl in a soft hug "I'm glad you're ok"

Juvia returned the hug and said quietly "I'm sorry for worrying you"

The redhead broke the hug and booped Juvia softly on her button nose "Don't worry about that. Ready to go home?"

Juvia nodded with a soft blush on her face, it always embarrassed her when Erza treated her like a little child.

"I will wait for you near the playground," said Erza and left the nurse's office.

A few minutes later, Juvia also rose and left the school as well. While she walked to their usual meeting spot, she thought a bit about her family.

Flashback

Juvia was an orphan, who was abandoned by her parents shortly after her birth. So the first three years of her life she grew up in an orphanage.

Then on one bright and sunny day, Juvia was busy practicing her sewing skills. Then one of the caretakers walked into the common room where all the kids spend most of their free time.

Porlyusica-san was accompanied by a tall, redheaded woman who also had a small girl in her arms who shared the same hair color.

"And here we are Irene-san. Here our children play and learn. Is there anyone you might want to get to know?"

Irene Belserion Scarlett scanned through the room and then to the girl in her arms. "What do you think Erza-chan? Is anyone here someone you might want as a sibling?"

She gently lowered her daughter to the ground and the small girl was off like a bullet. The moment her mother had walked into the wide room, her own brown eyes were fixated on a girl her age with blue hair, that was sitting alone at a table.

"Hello. I'm Erza Scarlet. What is your name?" Introduced Erza herself.

"J-Juvia is Juvia" replied Juvia shyly. Her unique way of speaking of herself in the third person weirded many people out, but not this particular girl.

Erza laughed and climbed on the chair next to Juvia "You talk funny, I like that. What are you doing there?" she asked interested, and quickly the two girls were talking about sewing and dolls.

After some time, Irene carefully approached her daughter and Juvia and gently introduced herself.

"H-hello Irene-san. Juvia didn't mean to keep Erza-san away from you" apologised Juvia quickly.

Irene just smiled down at the girl "My you are certainly very polite Juvia, but you didn't keep Erza away from me."

The buxom redhead then looked at both girls "Do you like her Erza?"

The small redhead nodded enthusiastically "Juvia is funny and it's fun to play with her"

"I see" Then she addressed Juvia "Juvia, do you want to know why Erza and I are here today?"

Juvia shook her head.

"I always wanted at least two children, but I can't get any more from the stork, so I decided to adopt a child. Would you like to come home with Erza and me? Then Erza would be your new sister, and I would be your new mom"

For Juvia, this sounded too good to be true. "Y-you w-want J-J-Juvia? Even though Juvia talks weird?"

This earned her a soft head pat "It is not weird, it is unique. So what do you say?"

"I would like that very much Irene-san!" said Juvia as loud as she could.

So the deal was sealed. Irene told Juvia that it would take some time until she really could come home with them, but she promised that they would visit as often as possible.

After two more months, all the necessary documents were signed and Irene had the legal approvement to take Juvia home and lime that the adoption of Juvia Lockser into the Scarlet family was finalised.

Juvia then grew up with Erza as her sister and Irene as her strict, but still very loving mother.

After they were done with elementary school, Irene began to notice that there was some kind of trauma deeply buried within Juvia's mind, so she took the hard decision to send Juvia to a mental facility so she could work through her subconscious trauma.

Irene and Erza visited Juvia whenever possible so the three years Juvia had to be there flew by like nothing.

When Juvia was then released, the doctors told Irene that they managed to overcome Juvia's abandonment trauma, but it would be possible that Juvia might keep a fear of loss her whole life. Nothing too severe, but a healthy family life would be elemental to not make it worse.

It was the summer after she got released from the mental facility, that Irene sat down with both of her daughters to tell them the truth about why Irene decided to adopt.

As it turns out, Erza's biological father had a meltdown shortly before Irene was due to go into labor. He shouted some nonsense about Irene being a dragon and wanted to kill her, he used a knife to slash her stomach.

Irene managed to knock him out and call paramedics, who rushed her to the hospital. The doctors could save her and Erza, but Irene's womb was forever damaged which made it impossible for her to bear children anymore.

Devastated, she then began to look into adoption after she finalized the divorce and restraining order against her ex-husband, and the rest is history.

Both girls then shared a long hug with their mother. After so many years together, all three didn't care anymore about who was blood-related and who wasn't.

Juvia then began her time at the Fairy School complex during the last year of middle school, where she met Gray. His indifferent attitude caught her interest for some reason and she tried everything she could think of to catch his attention, but it was like she was talking to air.

One thing that was always a constant in her life was the overprotectiveness of Erza. Erza was always someone who tried to follow the rules as much as possible, so the redhead joined the disciplinary committee as soon as possible.

That wasn't a club that made you the most popular, so to keep Juvia safe, Erza suggested they never tell anyone that they are sisters. While heartbroken at first, after some talking Juvia saw the point of Erza, especially considering what kind of people were going to Fairy High.

But at the end of the day, the two were sisters who loved each other to death.

End of Flashback

Juvia arrived at the playground where Erza was already waiting for her with two crépes in hand. A warm light shone in her brown eyes and she handed the chocolate crépe to Juvia and bit with delight into her strawberry one.

The two walked in silence and enjoyed their treat, when they finished, Erza began "Mom will say it as well, but I think you need to hear it from me as well. I told you so. Gray Fullbuster has a long track record of violent outbursts when he doesn't know what he should say. Someone like that isn't suited for my cute little sister!"

Juvia sighed deeply "You are right Erza-neesama, but that doesn't make it easier. And stop calling Juvia your 'little sister', you are only two months older than Juvia"

Erza shot her a mischievous grin "So that makes you the little sister" She stuck her tongue out and bolted down the street, with Juvia hot on her heels.

Scarlet home

The two girls tumbled through the door wrestling with each other. Juvia had managed to catch Erza just as the girl unlocked the front door.

"OWOW! I GET IT, I'M SORRY JUVIA! STOP BITING MY HEAD!" yelled Erza laughing loudly.

Juvia released her sister with a huff "Thank you Erza-neesama. Juvia feels much better now"

A fuzzy slipper then nudged Juvia off her sister. The two girls followed the bare leg and soon saw the chuckling face of their mother Irene.

"This sounds like an interesting tale. What kind of trouble did you two get on your first day?"

Erza huffed and jumped to her feet "We didn't do anything. We just got caught in the middle of it"

"I see. And did you end it as well?" asked Irene.

"Yes and no. Kind of? Urgh, let us change and then we can tell you the story" said Erza with a scowl. Irene nodded and while her daughters went to their large shared room, she made some tea.

Half an hour later in the living room, the two sisters finished their tale and Irene was seconds away from completely losing it. "So this boy, whom I told you time and time again wasn't right for you hit you?"

"Yes Mom" replied Juvia meekly.

"And then this other boy, who started at your school today, came in and protected you?"

"That is correct" nodded Erza.

Irene sighed deeply "I told you so Juvia. At least this Gray got his due punishment. Weirdly, he's so prone to violence, his father is so kind. Well, tell me more about this Natsu"

"He should have gotten me instead of intervening himself!" "He's so kind and gentle," said Erza and Juvia at the same time, only to then look at each other in shock and confusion.

"Juvia, the disciplinary committee's job is to break up situations like what you experienced. Getting involved is dangerous and against the rules" said Erza with a slight edge in her voice.

"If Natsu-sama hadn't rescued Juvia, Gray would have hit Juvia again before you would have arrived" replied Juvia icyly.

"What did you just call him? Don't tell me you start pinning after a new guy immediately after the last one dumped you!"

"And what if Juvia did? He's nice, and handsome and told Juvia that she's pretty! And Juvia learned her lesson, so she will take it slowly!"

Their argument continued until they got stopped by Irene who gave both of them a love tap on their heads.

"That's enough you two. You both make excellent points, so let's break it up. Erza, it's Juvia's choice who she is interested in. Juvia, try to keep Erza's feelings in mind, she only wants to protect you, so be careful and take it slowly."

"Juvia is sorry Erza-neesama. Juvia will be careful" said Juvia quietly.

"I am sorry as well Juvia. I only want to keep you safe" answered Erza. The two sisters then hugged each other.

Chuckling, Irene walked behind them and joined the hug "I don't know how I managed to get two bipolar daughters, but I wouldn't trade you for anything in the world. Now, who wants Pizza for dinner?"

This question was met with two enthusiastic cheers.

A few days later

Erza had been spying on Natsu for a few days already. She wanted to make sure that he didn't have any secrets that could hurt Juvia. It was surprising when she saw him interacting with Ultear, especially in the dojo. Everyone at school knew, when Ultear trained, stay away from her or experience pain.

But somehow, this pink-haired goofball managed to worm his way into Ultear's life. That was a good sign. He was also very gentle with his little sister Wendy and regularly spent time with Lisanna Strauss.

Erza liked Lisanna, she was way better behaved than her older sister Mirajane, Erza's nemesis. Oh sure, Mira was now the picture-perfect student, always polite and well-behaved, but Erza knew that the 'Demon' was still there.

Speaking of which, Erza noted that Mira had developed a habit of giving Natsu a bento box every day. This was suspicious.

During a free period, Erza decided to confront her yearmate.

"Hold it Mirajane," said Erza to the white-haired girl who was just about to enter the gym.

"Hm? Oh, what can I do for you Erza?" asked Mira innocently.

"What are you doing with Natsu?" asked Erza coming straight to the point.

"Eh? What do you mean?" replied Mira confused.

"Don't lie. You give him a bento every day. What do you mix in it?"

"Oh give me a break! I am far above such a petty thing as spiking someone's food! But if you need to know, I give him a bento because I want to. That's all"

Erza's eyes narrowed "I don't believe you"

"Suit yourself" replied Mira with a shrug "I'm not doing anything that's against the rules. Now if you'll excuse me" she turned around and opened the gym door.

"I DIDN'T DISMISS YOU, YOU HARLOT!" shouted Erza.

Mira froze in motion and turned around robotically "What did you just call me?"

"I think you heard me just well" replied Erza.

"In that case" sighed Mira, before she threw herself at Erza with a warcry.

Erza reacted quickly and met her rival's attack head-on.

Quickly, the two beautiful girls were entangled in a bundle of limbs, they pulled on each other's cheeks and hair and overall tried to get the upper hand using every dirty trick in the book.

During their fight, Erza lost her blazer, while Mira's shirt got ripped open. At some point, Mira had Erza's head between her legs, then she pulled the redhead's skirt up and delivered a strong slap to Erza's ass, causing her to squeal loudly.

"Yeah, who's the harlot now you bitch?!" shouted Mira and gave Erza another slap on the other cheek.

"F-Fuck YOU!" roared Erza. With a lot of effort, she broke Mira's hold and hit Mira's left boob with her fist.

"OW! Careful there Red!" growled Mira.

"BRING IT ON DEMON!" shouted Erza back and dove for the white-haired girl.

The two fighting girls were so engulfed in their scruffle, that they didn't realize that they had attracted quite the crowd of horny boys who were cheering for them to continue.

Suddenly, both girls got their heads slammed into the ground by a pair of strong fists.

"WHAT ARE YOU DOING?!" shouted Natsu out of breath. Wendy had seen the beginning of the catfight from her classroom window and, because she knew that Natsu was friends with Mirajane, texted her Nii-san that Mira was fighting the head of the disciplinary committee.

"YOU!" shouted Erza in surprise, but Mira had a completely different reaction. "WAAAAHHHHH NATSU!" she cried and grabbed his head and shoved it between her only bra-clad breasts "The mean ginger insulted me and ripped my shirt! Save me!"

Natsu flailed around in her heavenly valley for a bit until he finally managed to break Mira's hold and get some much-needed air back into his lungs.

"Hah~ Mira, I told you to stop doing that! And I also don't care who started it and why, I'm finishing it. I thought you changed!" he scolded fiercely. Then he turned to Erza and continued "And what is this? The head of the disciplinary committee fighting like a delinquent! If this is how you do your work, then I'm more than glad that I solve problems on my own!"

Both girls sat on their knees with atomic red blushes on their faces. This was the first time anyone experienced an angry Natsu and it was scary. He emanated such a dominant aura, that none of them even cared about their indecent appearance. Mira's shirt was still open and her bra in full view, while Erza's skirt was hiked up her stomach so that everyone could see her panties.

Natsu then turned to the still gawking crowd and roared "WHAT ARE YOU STARING AT?!"

This was enough to get them all to bolt away as fast as possible. Natsu then took off his blazer and threw it at Mira. Cover up and change Mira, and you should pull down your skirt Erza."

Only now did the two realize in what state of clothing they were, and with a cute yelp they did as Natsu suggested.

"Thanks for the blazer Natsu, I will give it back washed," said Mira with a soft blush.

"Y-yes, I thank you for protecting my chastity as good as possible and apologize for this whole situation" mumbled Erza, her face still bright red.

Natsu nodded with a grin and turned away from them. Erza and Mira meanwhile glared at each other.

"This isn't over yet Red!" Snarled Mira fiercely.

"Indeed Witch. But that is for another day!" Replied Erza with a sneer.

On a higher floor of the school, Lisanna and Juvia had watched the whole scene.

"Oh, Mira-nee, this was so embarrassing" moaned the white-haired girl. Whenever she was near Erza, Mira fell back into her old behavior.

"Erza-san and Mirajane-san sure are fierce. But Juvia is glad that Natsu-sama stopped them." swooned Juvia.

Lisanna shot a glance at her friend and then shrugged, she could have just imagined the added honorific.

Weekend

Natsu was once more doing his training routine in the school dojo. He was originally alone in the training building, but his sharp hearing informed him that someone else entered the hall.

He knocked over the dummy he was currently working on with a high knee kick, then he turned around to look who joined him.

In walked Erza, dressed in a traditional Kendo outfit and a Bokken in her hand.

"Hey there Erza" greeted Natsu the redhead cheerfully, "Here to train?"

"Indeed" replied Erza curtly. She was still a bit embarrassed around Natsu after her fight with Mira. To avoid his gaze, she looked around the doji and took notice of the many dummies that lay scattered on the floor "You intend to clean up before I start, do you?"

"Of course, I clean up when I finish" replied Natsu. Even his dense brain didn't miss the subtle demand to scram. He already went through this dance with Ultear and didn't want to bother with it today.

He then turned around and began lifting the dummies and placing them through the one-half of the dojo he was already occupying.

"Well?" came the voice of Erza just as he lowered himself for another attack routine. "Well what?" asked Natsu.

"I intend to train now, so would you put your dummies away now?" asked Erza.

"Why should I? I'm not finished with my training and there is more than enough space for both of us. When I train with Ultear we do the same" replied Natsu with a shrug.

"Excuse me?!" hissed Erza angrily "I said that I intend to train now, and I train in silence, so your presence is disturbing"

"Well then put some earplugs in or something like that. We can set a border and I won't cross it, but I will only leave when my training is finished"

With that, the pinkette turned away from the redhead, in his mind the discussion was over. But suddenly his instincts screamed danger at him.

Reacting quickly, Natsu spun around and caught the Bokken, which was aimed at his head between his hands.

"WHAT THE FUCK?! HAVE YOU LOST YOUR MIND?!" screamed Natsu.

"I kindly asked you to leave and you wouldn't listen, so I have to use force" replied Erza and tried to break their deathlock.

Natsu pushed her away by kicking her in the stomach. Erza gasped for air while Natsu jumped back.

"So when you don't get what you want you use violence?! How the fuck did you become the head of the disciplinary committee?!" shouted Natsu.

"Eh" Erza was at a loss for words, never had somebody challenged her authority like that. "I-I see that we can't solve this with words, and neither of us wants to back down, so I propose a kendo match to determine who stays and who leaves," she said after she regained her bearings.

"Not going to happen. I never used a sword so you're obviously at an advantage," replied Natsu glaring at her.

"COWARD!" yelled Erza and rushed him. But Natsu reacted quickly. He met Erza's charge head-on, and at the last moment, he jumped over her with a side flip.

He landed on a perfect handstand and used his legs to kick her into the back of her knees. Erza sank to her knees with a cute "KYA!", Natsu then jumped back in front of her, where he delivered an axe kick to her shoulder area, which forced her to let go of her weapon.

To finish her, Natsu grabbed the back of her head and slammed her face first into the mats on the floor.

Erza gasped loudly, she got beaten easily, without even getting a hit on her opponent.

"Have you calmed down now?" hissed Natsu. He was still pressing her head into the ground and sat on her back to stop her from getting up.

Erza squirmed under him before she went limp. "Yes," she mumbled meekly.

Slowly, Natsu let go of her head and stood up, but to be on the safe side, he grabbed her Bokken. Then he extended his hand to Erza, who softly took it and let him pull her to her feet.

"Just because you're used to training alone doesn't mean you are entitled to it every time in an open dojo. This whole behavior is unfitting for someone in your position"

Erza looked at the floor, not wanting to meet his fierce glare or answer him, so she just nodded.

Natsu sighed "Listen, I'm sorry for being so stubborn but I don't like getting pushed around, or getting attacked from behind. Respect is earned, not given. I learned that lesson very hard, and I don't want to beat you up all the time. It's not right to hit pretty girls"

Now Erza blushed like a stoplight. While she knew that many boys in school considered her to be very attractive, until now nobody has said it directly to her face.

"I-I'm very sorry for what I did Natsu. Guess my temper burst in the wrong way" she said quietly.

"Well, in the end, there was no harm done. Here" he handed her her Bokken back and then began putting away the dummies he used.

"W-what are you doing?" asked Erza. "I'm cleaning my stuff up" replied Natsu "Cutting an hour isn't a biggie, and to be honest, I kinda lost my mood to train"

Erza gaped at him and felt very bad for causing him to stop his training, even though that was exactly what she wanted just five minutes ago.

"W-wait" called Erza when Natsu was at the door to the male locker rooms.

"Yeah?" he asked.

Blushing, Erza said "I will buy you a snack as an apology for my behavior. B-But that doesn't mean I like you!" then she quickly ran into the girl's lockers.

"Uhm, ok?" said Natsu to the now empty room. He was too dense to properly appreciate his first encounter with a tsundere.

The snack was delicious and soon, both went their own ways. But something has changed. Erza realized for herself that Natsu was a good guy and a very good catch for Juvia. But on the other hand, something inside Erza now wanted Natsu for herself.

This something caused Erza to buy Natsu a snack from the vending machine or the cafeteria each day because her cooking skills were worse than bad.

Monday

Unaware of what happened between her new crush and her sister, Juvia was closely following Natsu while the pink-haired boy walked to his dorm.

She still hasn't worked up the courage to talk with Natsu, but she still wants to see him. And knowing which dorm room was his could be useful at some point.

"Man, why does Wendy write so much stuff on the shopping list? I survived three years with only cheese and fudge and am in perfect shape" complained Natsu to himself while he unlocked his door.

He bent down and grabbed the three heavy shopping bags full of groceries, but just before he entered his dorm, his sensitive nose caught an unusual scent.

"Huh? Juvia? Is that you?" he called into the empty corridor. Juvia "eeped" and came out from behind the corner she was hiding.

"H-how did you know Juvia was here Natsu-sama?" asked Juvia shyly.

"Your perfume. I have a good nose and caught your scent. Lucy's perfume smells like flowers and Wendy doesn't use perfume yet. So your mint-fruit perfume was very obvious to smell." replied Natsu with a grin.

Juvia blushed fiercely, happy that her crush knew so much about her already. "Hey, do you want to come inside for a cup of tea and some cookies?" asked Natsu suddenly.

"E-eh?" stammered Juvia "Y-yes, Juvia would be happy"

"Cool, come in," said Natsu and entered his dorm, closely followed by Juvia.

Inside, he told Juvia to sit down on the couch while he put the groceries away and prepared the tea and cookies.

The blue-haired girl elegantly sat down and looked around the dorm room. Her mother had enough money to only work part-time, so Juvia was allowed to live at home according to the laws.

"Your room is very clean Natsu-sama" complimented Juvia, she somehow would have imagined it way messier.

"Thanks, Juv, but you should compliment Wendy for that. To be honest, I'm a complete slob even though I try to keep it clean. That's why Wendy cleans my room every few days." said Natsu and placed a tray with two teacups and a plate of cookies on it in front of Juvia.

"Wendy?" asked Juvia with the slightest edge in her voice.

"My sister. She lives next door. Our parents work full-time and with a crazy schedule, so the law demands that we live in the dorms during the week."

"Oh" replied Juvia and took a sip of her tea. She didn't know what she should talk about now, so far all she knew about Natsu was that he did MMA and had a sister. Not too much for a conversation.

"Oh by the way, did that Gray jerk harass you again? If he did, just tell me and I will kick his ass!" exclaimed Natsu suddenly.

"N-no, Gray got suspended for a few weeks after you saved Juvia. Thank you again for that Natsu-sama" replied Juvia.

"With pleasure Juv. Hey, I wanted to ask you something for a few days now, are you and Erza somehow related?" he asked curiously.

"W-why would you ask that?" Juvia said nervously.

With a shrug, Natsu said "I saw you walking through town together a few times last week. You also have a similar smell. Gah, sorry for mentioning that, but I somehow have a nose that is better than a dog nose, so I always mention a person's smell. I know it's weird, sorry"

Juvia giggled and decided that Natsu had earned her trust for this. "It isn't weird Natsu-sama, it is unique. For your question, Juvia was adopted by Irene Scarlet when she was three years old. Erza-neesama is my older step-sister. Pl-please don't tell anyone"

"Cool, I bet Erza is a blast as a sister. I mean, she's a bit bossy but still very honest and nice. I'm happy for you. And don't worry, I won't tell a soul" said Natsu with a grin.

"T-Thank you Natsu-sama" Juvia gave him a beautiful smile.

Now her nervousness was shattered, and the two spent a very fun afternoon together where they learned a lot about each other.

Suddenly, Juvia's phone rang. "Excuse Juvia for a moment Natsu-sama" Then she answered the call "Hello?"

"Juvia, where are you? Mum made her special pasta for dinner and won't give me any until you're home!" came the voice of Erza over the phone.

Juvia threw a glance at the clock on the wall and saw that it was indeed dinner time.

"Juvia is sorry Erza-neesama! Juvia visited Natsu-sama in his dorm and forgot the time. Juvia will be home in a few minutes"

"Wait, Natsu's dorm?! Juvia wa-"

Juvia ended the call and said "I'm sorry Natsu-sama, Juvia has to go home now. Mum has dinner ready"

"No worry Juv. I'll bring you home, it's already late" replied Natsu.

Natsu ignored Juvia's protest and dragged her out of his dorm, but not without doing a ding-and-run on Lucy's door.

"I always do that when I leave, maybe she screams today" laughed Natsu while the two raced down the corridor.

"DAMNIT NATSU! I WAS IN THE TUB!" came a shrill voice from afar, which caused Natsu and Juvia to laugh.

Fifteen minutes later, the two arrived at the Scarlet home. "Well, I had fun with you Juvia. Maybe we can meet up for a movie or something like that sometime" said Natsu as a goodbye.

"Ye-yes, maybe. Juvia would like that. Good night Natsu-sama" said Juvia. She gave Natsu a quick peck on the cheek and ran into her home.

Natsu was beginning to get used to beautiful girls kissing him so he didn't react much.

Juvia was blushing up a storm.

Erza on the other hand had seen the whole interaction from the kitchen window, side-eying the delicious pasta in the oven.

'So Juvia kissed that idiot on the cheek. No big deal right? But why does it still bother me so much? Am I crushing on Natsu? NO! AS IF! He might be a nice guy and I might buy him a snack every day, but that doesn't mean I like him! TSUN~!'

Over the next few days, Juvia became a regular visitor in Natsu's dorm, where she also developed a fondness for pranking poor Lucy.

And done.

Ok, nearly six months between two chapters was a bit much, but I was busy with other projects (as you might see on my profile lol).

Still, I hope you liked it, let me know in the reviews.

I will focus mainly on this fic, but from time to time I will write for the other three fics, so I don't guarantee any fixed updates. I will still do my best.

Next chapter: Lucy

Till then

Bye :D
