Hello to every readers here, this is my first fanfiction and I decided to go for an OC centred adventure in the One Piece universe with high possibilities to see familiar character here and then. As it is my first try I'm sorry for the mistake I'm bond to make but dont hesitad to R&R, I'll be happy to have critism to help me getting better. Rated T for eventual violence and swearing.

*****************************************************************************************************************************************************

This story begin on the island known by the name of Koliru. This is a small island with no interesting resource for commerce and no special place for tourism but since it is located right on a major trade route of East Blue with no other island around a lot of commerce ship are forced to stop here to resupply and thus the island and it's only town sharing the same name has prospered.

So the appearance of yet another ship on the horizon was no big event for the townsfolk but as the approaching form became more clearly visible some people showed a worried frown, black flag and white skull : a pirate ship. Even if in this golden age of piracy it was unavoidable to meet some of them the occurrence was still rare on Koliru, the island was too small to interest pirates and the trade routes were well patrolled by marines. Even when pirates showed up they often came only to resupply as any other ship and didn't cause any trouble, after all most of the big player were on the Grand Line, the less daring pirates of East Blue would rather avoid to take on all at once the numerous ships stationed at Koliru at any given time.

This time some details were odd tough : the white skull on the flag was not human but some fishlike creature's skull and in place of the traditional crossed bones were two crossed lightning bolt.

"fishlike skull, does that means a merman crew ?"

On the port's dock a lonely figure was pondering on the incoming pirates nature.

"The only noteworthy merman pirates around here is Arlong's gang but that's not his flag, then is it some newcomer?"

It was a young woman standing on the wooden dock, relatively tall for a girl her long black hairs were going all the way down her back, her skin was white but not livid and her noisette eyes did not show any sign of fear at the sight of the pirate ship. She was wearing navy blue skirt and jacket with black legging but the clothes were made to allow easy movement rather than sexiness, the outfit gave an impression of military uniform though this was clearly not from the marine, impression reinforced by the finely crafted rapier lying on her side.

"But either Arlong or a newcomer should have little interest in this island, trading ship are more easily taken on high sea. If it was just another pirate ship they could just be coming for provision and rest but since they seem to be merman I doubt they would stop in a place so crowded with human"

At the same time on the pirate ship, a serpentine merman was talking with another one who seemed to came out of some H.P. Lovecraft novel

-"According to the information I gathered our target should be on this island captain"

The tentacle dude was a squid type merman and the captain an ell type, suddenly a shout came from the crow's nest.

-"I have the target in visual sir, she is at the port!"

-"Well it seems your skill have not dulled Ikatama, and how gracious of her to spare us the hassle of searching the whole town … ALL RIGHT BOYS TIME TO GET TO WORK!"

The ship aimed directly for the girl in blue who pulled back to the town's central place, the mermen quickly followed as well as a good nuber of the town's habitants. The pirate's captain then began to talk in a loud voice.

-"Hello everyone, as you can see we are pirates but fears not, we have no interest in your pathetic lives or this crappy town, all I ask is that the girl in blue over there quietly surrender to us, if so I might show some mercy and leave without burning the place"

The men who assembled there turned their gaze to the girl who did not seem afraid one bit from the ell guy statement .

-"And who might you be mister merman, understand that I cannot surrender myself to some unknown person just like that"

The girl asked in a dignified tone to which the merman answered with a smirk.

-"Opsy I beg your pardon milady, it's sure we don't meet someone with such a status as Yuri Delys, daughter of the marine head's in charge of the whole East Blue. I am the fearsome captain Kayabaki aka the ocean's lightning, now that the presentations are done will you behave and follow us?"

The townsfolk now looked at the girl with astonishment, the name of Delys was well known on all of East Blue.

-"My my, you seem to know a lot about me but for my part I have never heard of a fearsome captain Baka yaki to let myself being caught by third class pirates would bring shame to the Delys name, therefore I refuse to comply with your demand"

-" Watch your mouth little girl, you'd better not try my patience, if you don't behave we'll kill everyone on this island … AND ITS CAPTAIN KAYABAKI YOU LITTLE BITCH!!!"

-"Ah so, but you seem pretty reckless, exactly what my dad would call "une tête brulée", plus you don't seem very smart : killing everyone on this island would include me who you want as hostage and your crew, that would be pretty stupid isn't it?"

A big vein was now clearly showing on the merman's forehead

-"Then the name Baka Yaki is perfectly fit for you"

-"NOW YOU'VE DONE IT, I'LL MAKE YOU WISH YOU WERE DEAD EVERYONE AFTER HER!!!"

But Yuri had already begun to retreat.

"As expected of this brutish moron, now that I have his whole attention he should not do anything to the people of the town for some time, if I can keep him occupied until the marine send back up... The mayor as a direct denden mushi line with the closest marine base so it should not take too long"

But she was interrupted in her thought: a huge man, probably over two meter high placed himself between her and her pursuer.

"Damn I misread this one, I thought the townsfolk would not interfere out of fear but this town has a brutish moron of it's own"

-"Who the hell do you think you are uh? In this town the only one allowed to create trouble is this Saturbos-sama!"

The man then threw a punch at the closest pirate who happened to be the squid merman , caught by surprise he didn't avoided and the punch connected with a...

*ssqqquiish*

-"huh? Wait what?"

*tud*

The man was surprised by the weird sound before losing balance and falling to the ground, Yuri looked at the squid merman who was unscratched

"I see, physical bludgeoning attack won't work on this one"

Indeed when the man's punch connected it just slipped on the skin of the merman face thus throwing him off-balance.

"With this rubbery and slippery skin added to the sturdy constitution of merman he probably don't fear even gun outside of pointblank shot"

-" It's not like you mongrel could do anything to him but …"

The pirate captain was now just by the man who quickly stood up.

-"… to just put your fucking monkey hand on one of my men you really don't care about your life!"

-"Shu… shut rotten fish I'll send you back to the ocean !"

The man punched again but the merman just caught it in his hand before it connected

-"I'll give you the shock of your life … UNA GIGA CHOQUE !!!!"

The man was suddenly covered in a shining halo and for an instant his whole skeleton was visible for the world to see.

"Electricity? Some ell species are indeed able to generate bioelectricity, but the merman version is something else"

As the now blackened man once again fell on the ground Yuri was evaluating the situation.

"This is bad, now they will attack the people here if I flee, I can take out some of them and the battlefield is in my favor but they'll win with sheer number in the end, I need at least one other competent fighter if I want to stall them until the marines arrival …"

Yuri looked at the people around her, they were all shocked by the merman's demonstration not moving even a finger.

"But nobody here seem to be fit for the task … "

Then a voice coming from the place entrance was heard

-"What is happening here?"

... to be continued

And that's it for now, I'm working on the next part and hope to upload it soon, as a side note I want to precise that yuri is talking with the japanese "watakushi" typical of princess girl type in manga and using very polite form of speaking most of the time ( a bit harder to render in english especialy since it's not my native tonge).

I've tried to put some pun with name here as Oda sensei tend to do ( especialy zoro's move "eibi mayonaise onigiri" lol ^^ ) so don't hesitate to tell me if it was well done or completly lame.
