Kamen Pirates

Prologue

One Piece World...

The skies seemed peaceful as the sun rose into the sky. A new day was rising. This was the day Monkey D. Luffy set out on his journey to be king of the pirates.

However this day would be marred by something sinister. All over the world across the North, South, East, and West Blue, The Grand Line, and the New World large portals opened up spewing out all kinds of monstrous creatures.

Not just any creatures but Grongi, Unknown, Worms, Fangires, Orphnochs, Imagin,...all monsters that belong in the Kamen Rider worlds yet they are appearing here.

Very few people in this world sensed the change in the atmosphere. Among them was Red Hair Shanks and Hawk-Eye Mihawk.

The disturbance was felt through out the universe through dimensional barriers to other Earths.

Our Earth...Japan

Ran Hoshino knocked on the door of his friend Shiro Kenzaki. He wore black pants black tennis shoes and a shirt with the words 'Walking the path of Heaven, to rule it all. written in kanji. The door opened revealing Shiro's younger sister Sayuri "Hello Ran, Shiro will down in a minute. Would you like to come in?" Ran nodded and walked in not noticing the blush on Sayuri's face.

After a minute Shiro came down wearing khaki jeans, sneakers, and a t-shirt depicting Kamen Rider Den-O in his four main forms. "Hey Ran you're here already? I wasn't expecting you for another half-hour." "Mother said this 'The man who leaves on his journey early is never late for the journey's end.' "

Both Shiro and Sayuri stared at Ran till Shiro asked "What does that mean?" Ran thought about it for a minute and said "I'm not sure. I'll think about during our journey. Come on." Shiro nodded and after waving bye to Sayuri the two young men went on their way.

As the two were walking by a huge puddle Ran tripped on something as a truck came through the puddle and splashed Shiro completely. "Figures." Shiro said. Ran stood and said "Oh Shiro I'm sorry. I tripped on this thing." Ran held up a small red metal beetle.

"Where did that come?" Shiro asked looking at the beetle. "It looks like the Kabuto Zecter from Kamen Rider Kabuto. But that's impossible, it must be some child's toy." Ran said looking around to see if a child dropped it.

Shiro looked around too but then he noticed something on the ground. He picked up and saw that it looked like a rider pass from Kamen Rider Den-O. Hey Ran take a look at this..." Shiro said just before a bright light blinds him and he falls unconscious.

Elsewhere in Japan...

Daichi Kazama walked down a street minding his own business thinking about one thing. Why he had been bested by Ran Hoshino not once but twice. Ran got better test scores than him and later on in the championship match of a kendo tournament Ran defeated him.

Daichi shook his head trying to figure out why it happened. He was so engrossed he almost didn't notice the guy bumping into him till after he did it. "Watch where you're going. Idiot...wait what's this in my pocket?" He reached into to find the Knight Advent deck from Kamen Rider Ryuki before he was blinded by a bright light and passed out.

Meanwhile in England...

A young man named Ross was walking through the english countryside taking in the fresh air when he noticed a peculiar belt on the ground. It looked old and worn but still wearable. "I wonder who threw away this. I wonder if it fits me." He put on the belt and it fit perfectly. Suddenly a bright light appeared and Ross passed out.

Back in Japan...

Haruki Yamada sat at home waiting for his parents to come back from their floral shop when suddenly the doorbell rang. Haruki walked up to the door and opened to find...nobody. "Very funny. I HOPE THE POLICE CATCH YOU YOU BASTARD!" Haruki then looked down and noticed a strange looking box on the ground. It held a bunch of cards that were green on one side and yellow on the other side. As with the others there was a bright light and then he passed out.

In America...

James Kruger stood in the middle of a junkyard shooting tin cans with his airgun when a man walked up next to him. "That's some pretty good shooting. I tell you what let's have a contest. You win and I won't tell the owner you broke in here." James eyes widened but he nodded. "But if I win your ass is going to jail." James nodded again and the contest started.

Both had to shoot at ten cans each and who hit the most cans won. The stranger shot 9 out of 10 while James got a perfect 10 out of 10. "You won fair and square and to show you no hard feelings I want to to have this." the stranger said as he tossed something to James. James caught it and saw it was a green card holder with a bull's head on it in gold.

Bright light, James passed out, you get the picture.

Again in Japan...

"Miss Atsuko, there is a package for you and a package for Miss Rin." a elderly man's voice said as he passed Atsuko Ishikawa's bedroom. "Thank you." a girl's voice said as the door opened a 17 year old blond short haired Japanese girl. The door next to hers opened revealing her black haired twin sister Rin. "Hello sister." she said walking over to Atsuko.

"Hey Rin, did you hear that just now? Sounds like another suitor trying his hand at courting you." Atsuko said smirking at her older twin. Rin shook her head and said "Yeah sounds like you got one too." That made Atsuko's smirk disappear. "That's not funny."

As both sisters went down they noticed two wrapped packages on a table. One wrapped in red wrapping paper with Atsuko's name on it the other in black wrapping paper with Rin's name on it.

They each took their respective package and opened them. They couldn't believe their eyes. Atsuko had gotten a replica of Kamen Rider Ryuki's advent deck. Rin meanwhile had gotten a replica of Kamen Rider Ryuga's advent deck.

"Who knew?" Rin asked her sister before a bright light blinded the sisters and they both fell unconscious.

Back in America...

Eric Wojciechowski was sitting on the couch listening to his favorite Kamen Rider themes on his computer when there was a knock at the door. He paused the music and went to the door. Standing there was a man from UPS. "I have a package here for a Mr. Eric Wojohowitz..." "It Wojciechowski and I didn't order anything." Eric said looking annoyed.

The delivery held the package up to Eric and asked "Is this your name and address?" Eric nodded and said "Yes but..." The delivery man thrust the package in Eric's hands. "Then this is your package." He said closing the door leaving Eric all alone. "Hey wait a minute." Eric said opening the door to find no delivery man or a delivery truck.

"And if this was the Twilight Zone, Rod Sterling would have started speaking about now." Eric said as he closed the door. Eric placed the package next to his current issue of MMA Magazine. He opened the box to find inside was a cartoonish mechanical bat. It was mainly black and gold. Its head and face made up its body with pointed ears, clawed feet, wings and red eyes. Its fangs were also sharp.

Being a fan of Kamen Rider Kiva Eric instantly recognized the bat. "Kivat-bat the 3rd? I didn't

order anything like this." Eric then picked up the bat and he was blinded by a bright light and was knocked out cold.

One Piece World...

Ran slowly started to wake up and noticed Shiro out cold next to him. " Hey Shiro wake up. Hey! HEY!" Shiro brushed him away and said "Five more minutes Mom." Ran rolled his eyes and said "I'm not your mother its' Ran. Wake up." Ran then noticed there were a half dozen other people on the ground.

"Woah!" A sudden shout sounded from behind and Ran turned around to see an American around his age behind him with his right hand on his chest and breathing heavily. "Are you all right?" Ran asked. The American to him and said "No I am not. I passed out in my house somehow and woke up in the woods with a gold and black bat hovering six inches away from my face."

Ran looked at him and asked "What bat?" "He means me." a voice said and Ran turned to a tree and saw a familiar black and gold bat perched on a branch. "You're Kivat!" Ran said as he stood up. "That's right." Kivat said

"Hey Ran who are you talking?" Shiro asked as he woke up and stood next to his friend. Ran to Kivat and Shiro's eyes bulged "Ran...that's..." "Kivat from Kamen Rider Kiva. Why he's here and where-ever here is I don't know but Mother said this..." "Ran, now is not the time for one of your mother's famous quotes."

"Oi what's with all the noise?" A man's voice with a scottish accent asked as a man with purple hair woke up. "You guys are loud enough to wake the dead." Ran turned to him and said "Well excuse us for trying to figure what is going on."

The American walked up to Ran and said "Maybe we should wake everyone up first before we work on where in the world we are." Ran nodded and the Scottish accent man walked up to the people who hadn't woken up and yelled "WAKE YOUR FUCKING ASSES UP!!!"

Shiro stuck his pinky in his ear and said "And he says we're loud enough to wake the dead." Ran nodded and was about to speak when a familiar voice said "Ran Hoshino, so you are involved in this as well." Ran turned around and was face to face with..."Daichi Kazama."

The two stared at each other till Shiro got between them. "Let's wait till we find out where we are and what's going on here." Daichi nodded. Shiro turned to his best friend "Please Ran..." Ran sighed and said "Fine."

As soon as everyone woke they all started getting worked up about what had happened to them. One of the guys, another American pulled out an air gun and and started pointing it at everyone before he was tackled by the first American and the gun wrenched from his grasp by Ran. "Pointing a gun at people isn't going to help matters sir." Ran said twirling the gun in his hand.

"Would it help matters if I explain what was going?" A voice said and everyone turned to see. "Is that Koji Seto?" Shiro asked "No. My name is Wataru Kurenai." Wataru said as Kivat flew towards Wataru and landed on his shoulder. "I apologize for bringing you here but circumstances beyond our control we needed to bring you here."

"And where is here exactly?" Ran asked. Wataru smiled and said "A world in an 'Era of Dreams' A world enveloped in a 'Age of Piracy." "In other words you've sent us into the One Piece manga." Shiro said. Wataru nodded. "But it's not real." Shiro said. "Who says so? You're here aren't you."

"Why?" Ran asked.

Wataru sighed "Well we're not sure but practically every monster myself and previous Kamen Riders have fought have invaded this world. From Fangire to the Grongi they are attacking this world and unfortunately myself and the other riders can't go after them."

"Why not?" One of the only two girls asked. "All I know is that if too many people from too many worlds converge on one specific world for too long and well the results aren't pretty." Wataru said.

"What's this then?" asked the purple haired boy angerily his eyes turning red.

"Well first of all I'm not staying here unfortunately, second and most importantly every one of you is from the same world so it shouldn't be a problem." Wataru said before continuing "Each of you before you came here came into contact with certain items that will of course help you to defeat them."

Kivat then flew off Wataru's shoulder and landed on the American standing next to Ran. Everyone grabbed something except for the purple haired guy. "All I grabbed was a belt I don't even have that." Suddenly the belt appeared around his waist. However now a stone was embedded into the front of the belt.

Several of them had advent decks from Kamen Rider Ryuki. "Excuse me Wataru-san but I doubt well run into many mirrors in this place." said the other girl who except for having black hair instead of blond hair looked just like the first girl.

Wataru chuckled and said "Shiro Kanzaki-san was kind enough to modify the decks a little. It was a little hard contacting him since Mirror World was sealed off at the end of the Rider War. Thankfully that means no mirror monsters would come here. But as I was saying he modified your decks. Go ahead try it."

The blond haired girl decided to try it.

Pulling out her advent deck with her left hand, a belt came out of nowhere. She threw her right arm across his chest to the left and yelled out, "HENSHIN!"

She inserted the Ryuki deck into the V-Buckle from the left side. Three reflections of the red dragon-like Ryuki Armor all descended onto her body.

"HOLY SHIT!" the girl said as she looked over her new rider armor. Wataru chuckled as the others stared at her. "Of course Kanzaki-san changed the transformation pose for the Ryuga deck. Just do the opposite of Ryuki and it'll work."

Wataru stood back and began to fade. "A few last things before I leave. One, don't worry about people missing you back home. We froze time there. Two, I'll check up on you every once in a while and three, don't die." Wataru said as he faded out.

They all stared at where he once was as Ryuki reverted back to her human form. "Okay so we've been chosen to fight monsters with advance battle systems and we've been dropped into a world that we thought was fictional and now we're all alone." The first American said.

"Back home this would be called kidnapping, corhersion, among other things." The only man who hadn't spoken before said.

Suddenly 9 motorcycles appear out of nowhere. In order they were Kabuto's Kabuto Extender, Kiva's Machine Kivaa, Kuuga's TryChaser 2000, Den-o's Den-Bird, Zeronos's Machine ZeroHorn, and 4 Ride Shooters from Kamen Rider Ryuki.

The 9 new riders all looked at each other before they ran to and got on their respective motorcycles. The cycles started up and they drove off over the horizon.

Next update will be by next Monday
