1 Prologue

One Piece,the treasure seeked by every pirate in the world.Currently only three people have managed to find it,but the first one created it:Gol D. Roger,Monkey D Luffy and the story of whose this is...Kuroken's story!

In a beautiful town close to the sea,a single child was pouting.His hair was pinch black and his eyes were light brown.He was wearing a simple white shirt and blue pants.He was really angry at that moment.

"And I even learned Observation Haki...GRRRR How dares that old man to make me leave my house and put me in this strange town!"

His name was Kuroken.His grandfather forced his to learn Observation Haki just at the age of six.It was crazy!Even Gol.D Roger or Monkey.D Luffy waited for years before having the chance or power to learn haki.But his extreme talent managed to do that just at the age of six!Now he was seven and god knew how strong!

He also had eaten a Devil Fruit.He slowly descended from the mountain he was on but at a road of it he saw a twenty something old person.He was probably in his early twenties.His hair was orange and short while his eyes were blazing red.

He was around 1,88m and at his waist there was a sword and in his back there was also another sword.He was wearing a black cloak and a scar went across his left eye.'Who is he?'Kuroken thought but then jumped before the person.

"What is your name?!"He shouted.The black cloaked man smiled,"Are you lost kid?"Hearing the black cloaked man call him kid made him furious even though he was one,"Answer my question!" Then he finally replied,"Fine,fine.My name is Fukuro,Aka Fukuro,a pirate."

"Hahaha, a pirate?!"Kuroken laughed loudly.He clearly didn't believe Fukuro."You don't believe me?Then what about this."He slightly unsheathed his sword located at his waist and a gust of wind quickly cut a tree in two.Kuroken gulped and slowly said,"Oji-san,I believe you."even with his skills in every haki,He barely saw his movement.If he was a pirate he shouldn't be from the South Sea or the GrandLine but the New World which now is called Gold World.

"Follow me,I will take you to the city."Fukuro said and bowed respectly,playing with him.Kuroken remained silent and followed him.After a few hours instead of reaching the city,they went even more far away from it."What the hell!You are just making us go even farer!"Fukuro felt like going into a corner and crying.Even a child saw that.

Fortunately for him,Kuroken was no ordinary child so no other child expect a few should be able to see through his direction sickness if they are six or five.Suddenly something moved in the bushes.They both were relaxed so before any of them could act a brown bear appeared and tried to bit Kuroken.

"Be careful!" Fukuro unsheathed his sword and the bear was cut in a hundred pieces.Kuroken was left with fear in his eyes.He immediately hugged Fukuro like it was natural.Although he was trained,he was still a child.Children are children,adults are adults.

Suddenly six people started to run towards them from the side they were coming.They all were muscular.One had a mohawk which was red and thick lips.Another had red hair and blue eyes.The other one had crimson hair and green eyes.Another had long silky silver hair and purple eyes.The others were wearing cloaks.

"Captain!"

They all yelled in unison.Fukuro's face changed to one of happiness."Ah!"Fukuro said and Kuroken also looked.He looked at the beautiful one-chan,the one with silky long silver hair and purple eyes.But he noticed something behind them.The next moment he didn't hesitate and ran the opposite way.

"SAVE ME!MONSTER!AAA!"Fukuro raised an eyebrow,"Come on I saved your life.Don't call me monster!"Kuroken felt like slamming his face on the ground," I mean there is a monster behind then!"Furoko looked at them and saw a twenty meter's black bear."Oh shit...RUN!"They both ran in unison.

But Kuroken was slightly faster."Defend me!You are an adult you need to protect the children!"Fukuro shouted,"Don't joke with me!But then…"He stopped running turned back and unsheathed his sword.Poof,poof,poof.The twenty meters black bear no longer lived.

Mazir's jaw reached the ground and his eyes almost came out."A-a-am-Amazing!Ojji-san I never knew you were so powerful!"Furoko crossed his hands,"Of course I am! I am the

Great Pirate Emperor,Sword Beast,Aka Furoko!"

"Ojji-san,for a moment you looked cool there."For Fukuro,these words seemed like a hammer."Urgh,you mean I was never cool before?!"Kuroken laughed,"Of course you weren't!You think two swords are cool?You old timer!"Fukuro's strength faded away as he fell on the ground but before that the silver haired one-chan saved him."Captain!"She yelled.

"Is he dead?"The mohawk guy asked nervously."Of course not!"The onee-chan shouted.She checked his pulse and then sighed a breath."He is still alive…"The mohawk guy teased,"What,if he was dead would you die with him?" The onee-chan took out a pistol from her belt and shot.But each bullet were stopped by a finger."That is not good…"

But the mohawk guy in his mind was sweating,"That was close...If I was just a half a second later I may had died...It is her fault to play with so many weapons...As expected of our doctor and strongest female in the crew…"

"Are you okay..Mister Not cool?" Kuroken teased Fukuro who instantly woke up.I am not a mister not cool!
