Hey guys, this is my first fanfiction so it may not be too good, I got the idea for this when I was reading "Dragon Slaying Pirate?" By KuroHi91, my story is a lot different, but you may see some similarities so I wanted to give KuroHi91 credit for their ideas even though I'm going to put my own original spin on things, log story short, in a way, this is kind of like a fanfiction of a fanfiction...well, not really, but enough from me lets get on with the story.

My name is Natsumi Kaori Nagato I'm 17 and apparently I look like a guy, who knew. I have short black hair with bangs that swoop over and cover the left side of my face, I have black charcoal colored eyes, I'm 5ft 8in and I'm fairly bony, yet pretty muscular. I normally wear jean shorts and my favorite black hoodie with a t-shirt underneath, along with some sneakers and a black baseball hat, so I guess that doesn't really help my boy like physique.

I'm trained in Kendo and Karate, I know how to use a Bo Staff, Nun-chucks, and swords, thanks to my older brothers (Kaito age 24, Tsuna age 27, and Kamoko age 30) who are all complete martial arts freaks, only the strongest survives in our family, but oh well, what can ya do? Family is family, but, sadly, my family died a few years ago in a robbery, not even my brothers could fight off guns, they weren't bullet proof.

But despite all that I've had a happy life although I've always wished that my life could be like an anime, like One Piece, I mean, Devil Fruit powers, pirates, how much more excitement can there be, too bad reality is boring, at lest that was what I thought, until my reality changed...

That morning was like any other, I would wake up at 6:30 giving me only 5 minuets to get ready for school, I ran around the house and grabbed all my stuff, including the mini survival kit I always keep with me, I live in the city, believe it or not I've actually been mugged before, well, I got off scott free, the mugger, not so much, lets just say he needed some serious medical attention when I was done.

Anyway I was on my way to the bus stop and was crossing the street when BAM! I didn't even see it coming! A tractor trailer headed straight at me, but right before I collided with it my vision blurred and everything went black for just a moment then I woke up, I was on the edge of a cliff overlooking the ocean.

As I stood up my clothes were baggy and and the world felt...bigger, I took out my pocket knife and used its reflection to look myself over, and boy let me tell you, I was surprised to find that I had been turned into a little kid again, I looked to be about 7 or 8 and my eyes, which were normally a charcoal color, had turned an intense electric blue, they almost appeared to glow.

I was gonna go and wander off but the instant I took one step knew my baggy clothes would get in the way, so I decided some modifications were in order, so I pulled my mini sewing kit out of my bag and got to work, in about a half an hour I was done.

So I turned around and walked into the forest that lay behind me.

After a while I heard some yelling a little farther in front of me, then a boy crashed through the bushes yelling, "Ace! Hellllppppp meeeeee~" behind him was a gigantic bear, and without thinking ran up to the beast and involuntarily yelled, "Shadow Slash!" And ran, what felt like, straight through the bear, hitting nothing but air, but when I turned around the bear was on the ground, dead, a gaping hole in its stomach.

"Luffy!" Another boy yelled crashing into the clearing, followed by another one.

My breath hitched in my throat as I realized just who was in front of me, the boy that was running away was Luffy, the Monkey D. Luffy, and the first to come through the bushes to help him was Porgas D. Ace, and the other one was Sabo. I slowly tried to slip away undetected, but it didn't really work.

"What happened here?!" Sabo yelled, looking at the hole in the bear.

"That guy saved me!" Luffy yelled, pointing to me, wait, guy?! Hmmm...this could be interesting, like a new little game...yes...a very fun game...

"Who are you?" Ace asked.

"I'm Nagato K. Natsumi, but Natsumi is kind of a Girly name, so I prefer to be called Natsu." I stuttered nervously, oh my god! My favorite anime characters are standing right in front of me!

A few hours later~

After a while I was able to act casual with Ace, Sabo, and Luffy, they're so fun to be with, right now I'm eating dinner with them, the bear from earlier.

"So, Natsu, where are you from? You don't look like anyone, from the city or from Grey Terminal." Ace asked.

"Oh, well, I ran away from home, I was stowing away on a cargo ship, I was planning to stay on until I found a really nice place, but I was found out and thrown off the ship here." I sighed, scratching my head, what am I gonna do if they don't buy it?!

"So, why did you run away?" Sabo asked.

"I had no other choice, my parents and three older brothers died in a pirate raid a few months ago, I have no where else to go." I said sadly, I may have tweaked the truth, but it was still a sensitive topic.

"I see..." Ace said, he looked so...angry, his fists were clenched as he looked at the fire, then his face lit up and he looked at me, then the others and said smiling, "How about, tonight, we become brothers?"
