Well, I'm writing this because of a major writers block in my other story.

This is a LuffyxAcexLawxKidd. I hope you'll enjoy it :D

Plot: Luffy, Ace, Law and Kidd all live in the same orphanage together and because they live in the same dorm together they consider each other brothers. There have always been some little fights between them, but everything changes when they all fall in love with they're youngest brother, Luffy. Who will be able to win the boy's heart? Or will they all lose to a certain green haired swordsman?

This is an AU and there won't be any devil fruit powers, but auras instead.

Luffy: 15 years old

Law: 17 years old

Kidd: 16 years old

Ace: 17 years old

Chapter 1

It was just a typical morning like any other, but it was a day that would change the brothers lives for good.

Luffy had recently made a new friend at school. A green haired guy who constantly carried around 3 swords. Neither one of Luffy's brothers could stand him. None of them knew exactly why, but the way he clung to Luffy disgusted them in more than just one way.

"Luffy! We're going to be late because of you again!" Ace yelled impatiently.

"Sorry!" Luffy said while coming down the stairs with a ridiculous huge smile plastered on his face.

"You don't look like you mean it." Law said while turning around to get to school.

"That's not true!" Luffy pouted.

It wasn't the first time this had happened, but this time it made Law feel all fluttery. A feeling he didn't like at all.

"Oi Luffy! If you get into a fight again, we won't help you! I'm sick of having to clean up your mess!" Kidd scolded him.

Luffy got into fights on a daily bases, but even though he was already 15 he didn't have any aura at all. Normally a persons aura awakens when they turn 13, but Luffy's never appeared.

"He's right Lu! You always challenge the ones with the greatest auras to a fight, even though you don't have any!" Ace joined in on the scolding.

"Whatever! Not like I need any help to beat those guys!" Luffy exclaimed proudly.

"Fine. Let's see then how you'll do today if we don't jump in to help you." Law said with a smile plastered on his face. Everyone knew that he liked experimenting with all kinds of things and most of all with humans. Kidd and Ace immediately noticed that he was up to something and they decided to just go with it. After all, one of his experiments caused his aura to awaken when he was only 11 years old.

The day went quite normal like always. Until the lunch break started.

"He's doing it again. You sure we shouldn't help?" Kidd asked while calmly drinking his juice. "Yes. Just leave him be for today. We can go and watch though." That said Law walked over to the crowd that had gathered. He was one of the tallest students, meaning that he could see perfectly fine from the back of the crowd.

"Oi Law! What do we do with Ace?! There's no way he'll just sit still and watch when Luffy's in danger like that!" the red head called and ran over to stand next to Law.

"Don't worry, he's got into a fight with the teacher again and wasn't allowed out for the break."

"Oh, okay. How's Luffy doing?"

"You're taller then me. Just look for yourself."

"Oh.. As lousy as ever.."

The crowd got smaller every minute until only the two brothers were left watching. No one was in the mood to watch a kid without any aura getting beaten up. And if a teacher would happen to show up they'd probably all get detention for not stopping the fight.

Luffy was up against Enel today. He had one of the strongest aura's in the school.

"I just don't get him sometimes! Why would he chose one of the strongest in our school if he knew we wouldn't help!? Is he an idiot?!" Kidd yelled out in frustration. This was getting on his nerves. And he was sure to pay Enel back for what he did to Luffy after school.

"In fact, he is an idiot. Not like you didn't know that already." Law said, calmly observing the fight. At least he looked calm, but Kidd could tell that he was about to snap and kill Enel.

"Law! Kidd!" A furious Ace came sprinting out of the building. "What the hell are you doing?!" He stopped right in front of them. "Why aren't you helping Lu?!" he was about to sprint over to his little brother when Kidd knocked him down.

Luffy was in a horrible state. He was lying on the ground coughing up blood when Enel kicked him in the stomach once more.

"You should just stay down. Someone like you can't win any kind of fight." Enel said while kicking Luffy back onto the ground.

"Shut.. up.." Luffy coughed.

"Huh?!" Enel was now furious, not only did this weakling challenge him to a fight, but now he's telling him to shut up?! Enough was enough. He focused all of his aura into his hand and hit Luffy right in the stomach causing him to crash right into the school building 30 meters behind him.

The brothers arguing was interrupted by a huge crashing sound behind them.

Normally in a situation like this they would've killed Enel in an instant, but this time they weren't able to move an inch.

The sky around the school suddenly turned as dark as the night and not a single student said a thing or moved an inch. It was an aura stronger than any they had felt or seen before. Even though no one around them was using their aura they were frightened. They don't know where it comes from nor do they know who it belongs to, but they feel as if they could die if they made even the slightest movement.

A furious Luffy crawled out of the shattered wall. There wasn't even the slightest sign of aura around him, yet the closer he moved towards Enel and the brothers the stronger the pressure of the aura became.

"I said… Shut. Up." His eyes were more intense than the brothers had ever seen and the words send shivers down their spines. The moment he faced Enel he clenched his fist and hit him in the face. The impact was so big that he was send flying through 5 different building until he finally came to a stop.

After Luffy had hit Enel the sky turned blue again in an instant and he fell on his knees.

Ace, Law and Kidd immediately ran up to their youngest brother to see if he was alright. When they had reached him they didn't see a single scratch on him. It was as if all his injuries were healed.

"I told you I didn't need your help!" He said with the brightest smile they had ever seen.

That smile made them fall in love with him in an instant.

Kidd's face turned as red as his hair and he turned around to get back into school as fast as possible.

Ace had a slight blush on his face and found a sudden interest in his shoes.

Law's heart beat tripled and he couldn't take his eyes off of his brother.

"What's wrong with you guys?" Luffy asked curiously as he got up.

Ace looked up. Kidd stopped and turned around. Those words were what made them aware of the fact that they were all feeling the same. Those words were what made them rivals for live.

I hope you enjoyed this first chapter! I'll be sure to make the next chapter longer than this one! :D

I'll try to get over my writers block as soon as possible and upload another chapter of my story Teach Me!
