Okay I was told I usually go out early in my stories because the huge episodes count of the series so I chose to do a RWBY one. They aren't very long and is only into it's 4 season.

I don't own either one piece or RWBY. That should go without saying.

Plot: It has been over millennia since the great Pirate Era ended with Straw Hat Luffy finding the One Piece. Over time the world has changed the World Government fell, war after war sprouted up. Island after island was destroyed. The battles somehow even shattered the Moon. All most all sentient creatures will killed, only small pockets of two races survived Humanity and Faunus. After the wars there were only 6 islands left, the inhabitants called it Remnant. The people then forgot about the olden days when brave or foolhardy men and women went out to sea for adventures. Where a person could get super-powers by eating a horrid tasting fruit. But on these islands had a horrid pest problem, the creatures of Grimm. They were around on these islands even back when Gol. D. Roger sailed the seas. They fed off of negative emotions and spawned everywhere. With the ancient war they grew bigger and stronger and once again both races were almost wiped out until the discovery of Dust. With this they fought back the creatures of Grim and on those islands 4 kingdoms were forged the center kingdom Vale, the western kingdom Vacuo, the northern kingdom Atlas, and the eastern Kingdom Mistral. Due to exposure to dust both races gained an aura and semblances. But like all sentient species war is nature. Once they could defend against the Grimm they went to war with each other. Kingdom against Kingdom, Human against Faunus. But peace had come let's just see how long that lasts shall we?

Prolog: The Surgeon named Arc

My name is Jaune D. Arc if you didn't know. A member or was a member of the Ark family. The Ark line while not as well known, as the Schnee or some of the other older bloodlines was still a family of warriors. They were and still are Hunters and Huntresses, Generals and even Royal Guards. I wasn't by nature; I would have been reading medical journals and textbooks rather than practicing a sword style that didn't feel right. I wasn't an Ark defender as the rest of the family was. Once this became apparent after my former father unlocked my aura and tried to train me at 5. I was kicked out of the Ark family into the Arc line.

It was an old tradition from the time the kingdoms were created to kick us bastards and those who were not worthy of the Ark blood in their veins to forever dishonor us apparently. It was also one thing the Ark line tried to keep quite about. Even after all this time they kept up the old traditions. They prided themselves on passing on the old way of life. Heck that's why even in this time of a stable population; had eight, or seven children now.

When I was kicked out the only thing I thought about was how I oddly didn't seem to care. Maybe it's due to the fact that even in my oldest memories I never being close to anyone except my older twin Jane. My former father was either always training my older sisters or off on missions so I before he started the training he was more or less just the stranger I lived with. My former mother treated me with nothing but pity for me; I think she might have known the banishment was coming. My older sisters treated me as nothing but an annoyance so we spent as much time together as an Schnee and a Faunus. Once my former father started to train Jane and me; Jane started treating me like I was made of the most fragile of glass.

Then the day it happened I was 6 and my former family just took me to a park near the walls of Vale. My former mother gave me 500 lien to help me get by for a few days. I spent all of it on a bullhead ride to Vacuo. I spent a few weeks there before the Vacuoan police found me. I was sent to an orphanage. I was sent to school but thanks to my intellect I went to 1st grade all the way to 12th in 4 years. I was offered scholarships from tons of colleges and programs. I went to a special program to help me become a surgeon. I always found the human/faunas anatomy fascinating. I somehow finished med school within 3 years. I was content with just being a surgeon in the Kingdoms but then I found it, or well them if I am being technical.

I was on a beach in Vacuo right after my graduation from med school. A huge tsunami came in a few weeks earlier and there was stuff from the sea floor everywhere on the beach. I stumbled across an old barnacle covered chest. Within it held three things a sword taller than I was at the time, an old journal, and a odd heart shaped fruit.

The journal belonged to a man named Trafalgar D. Water Law, and told a bunch of crazy nonsense about his time with the famous Pirate King Monkey D. Luffy, and how he asked them to find his fruit after he died and throw it into the ocean along with his sword and journal. I thought it was the Journal of a madman till I got to the techniques of his Ope Ope no mi or the Operation Operation fruit, and how it required tons of medical knowledge to use it. Once I went over it seemed less insane.

So I decided to eat the fruit. I felt it change me to my very soul. The fruit changed my aura, my very soul. The base knowledge on how to operate my Room flooded my mind. That was when I knew that I could help people more than just a simple surgeon, I could go out to the villages outside of the kingdoms and help them defend them from the Grimm and heal the wounded and sick that had no access to any hospitals.

But first I had to learn how to fight. I trained out in the wild just outside of Vacuo for 4 years. For the first year I trained in Hand to hand/Swordsmanship to get used to fighting with and without my new used 'scalpel'. Thankfully I took up using Kikoku and Law's style much better than I did the Ark defender style. On the second year I worked on Haki/aura control. I am now a proud user of Observation and Armament haki and my aura pool and control grew greatly. On the third year I practiced my 'semblance' in battle and in the hospital I was working in.

I needed to raise the control of my aura. Maybe because aura wasn't always part of the body devil fruits reacted differently when I use it I feel a slight drain on my aura unlike Law who said it drew from his stamina. So to use it in battle or in the ways they were told about in Law's journal I needed to get be able to produce enough aura to use my Room.

My 4th year was more or less a mix of things. I went out to buy a simple dust gun and special ammo for it, polished the skills I was working on before. Then just spent more time at the hospital working trying to save enough to pay the entrance fees for a secondary combat school. I had my eyes set on Beacon.

You don't technically have to have gone to a Hunter trainer school to begin with you just have to pass their acceptance test and pay the tuition. Going to a school helped since you had the tuition passed and were always given a spot. I passed the base test and was able to get in so here I am on a Bullhead going to Beacon trying not to throw-up from my damn air sickness. But even that couldn't take away a small smirk from my lips. I can accomplish my dream of helping people.

There will be no updates for a while I'm currently doing a self beta-reading on this story to try to clean up the miss spellings and bad grammar.
