The path of twilight

Chapter 1

Prolog

(This is a continuation to my one-shot story Twilight. Or something like that. See, I'm saying this happened after Twilight, because I really liked the way that turned out, and I needed an excuse for Riku to have left Destiny Island with out Sora or Kairi knowing about it.

So, this story will be a crossover with the anime One Piece. After all, if Riku needs to learn all new, kick all sorts of butt, fighting styles/attacks, why not in the One Piece world? All right, so the story starts about seven years after kingdom hearts 2. ((For those of you who need to know: I trying to do this more anime-ish, so I'm going to reveal what's happened to Riku since he left Destiny Island later in the story.)) As for the One Piece timeline, lets say this chapter happens before Luffy and co. met Sanji.)

START

Wealth, fame, power. The man that had everything in the world, Gold Roger; the Pirate King. Before being executed by the Marines, Gold Roger said something that would send people to sea for years to come. "My treasure? If you want it, I'll let you have it; I left it all at that place."

Seeking their dreams, men and women alike now set out to sea, heading to the Grand Line in hopes of finding the legendary treasure: One Piece.

The sea was could be a very quite place. A young man was finding that out the hard way. The man was in his late teens, around seventeen years old. He had somewhat pale skin. Dressed in a light red tank top, and a pair of black shorts, the young man didn't really look that threatening. In fact, with that straw hat he was wearing, and the pair of sandals he had on his feet, he looked rather harmless. One thing that would catch your eye was the fact he had a scar under his left eye, running horizontal about five inches. However, the scar really didn't change the somewhat innocent look the teen had, with his slightly shaggy hair black hanging down in his eyes, which were also black.

"I'm soooooooo board!" The teen said as he feel back onto the wooden plank, the deck of a ship. "I just wish we could get some wind blowing soon. We have to get to the Grand Line." The teen said in a slightly winy voice. As he stared up at the sky, wishfully take a glance at the sail behind him, hoping to see it move at lest a little. "You do know that staring at the sail won't make the wind blow, right Luffy?" Came a female voice from the side of the straw hat wearing teen, Luffy.

Turning his head slightly, Luffy could see a female around the age of eighteen standing there. She had a fairly normal height, standing maybe 5'6/5'7. The girl had light orange hair that was kept rather short, but the bangs were still long enough to fall into her eyes. The girl was wearing a light blue shirt, with a white stripe running across her midriff, and a light yellow short skirt. "Aw come on Nami! I'm sure that the wind will blow soon." Another, slightly higher pitched voice came from behind Luffy and the girl, now known as Nami.

Another boy around seventeen could be seen standing there. This boy was taller then the Luffy or Nami, standing maybe 5'11. He had dark skin, and black curly hair that fell down covering his neck. On his head was a light green hat that, if you looked at it from the right angle, looked like a military helmet. The boy was wearing a pair of dark brown overalls, and a pair of black combat boots. Another thing that stood out was a large bag hanging from the boy's side. Finally, the thing that stood out most out the boy was the fact that his nose was almost six inches long.

"Usopp's right Nami; if we wait a little longer I'm sure that the wind will pick up again." Luffy said, glancing between the long nose boy, also know as Usopp, and Nami. "Hey Zoro what do you think? Zoro? HEY ZORO!" Luffy yelled, looking farther back on the ship at the fourth, and final person on the ship.

Lying on the deck of the ship farther back, there was another male in his late teens, most likely around nineteen. He had light green hair that was cut short, and you couldn't see his eyes due to the fact he was sleeping at the moment. On his left ear there were three earrings that looked like small gold bars, hanging right next to each other. The man was wearing a plan white t-shirt, a pair of black pants, and a pair of black boots. Also, there was a black headband tied around his left arm. The thing that stood out about this man was the fact that he had three katana's hanging from is right hip; two in black sheathes and on in a white.

"Don't waste your breath Luffy; once Zoro goes to sleep, it would take a cannon blast to wake him up." Nami said, looking at the green haired teen sleeping. Hearing what Nami said, Luffy's eyes lit up, and a smile broke out on his face. "Well, we do have a couple cannon's on this ship, why not wake Zoro up with one of them?" Luffy said with a huge grin.

"If you do that, Zoro will most likely stab you with one of his katana's." Usopp said, shaking his head slightly at Luffy's idea. "Why do boys always want to shot something?" Nami muttered to herself, looking at Luffy. "Anyway, why don't you two try and make yourselves useful…or at lest try not to break anything." Nami said as she walked over to a beach chair set up on the ships deck, and sat down in it.

About four miles from where Luffy's ship was sitting in the water, there was a small island. The island wasn't really that big, and was mostly covered in trees and other vegetation. At the beach, there was a small dock, used mostly for fishing ships to dock. However, currently a different, much bigger ship was docked there.

The ship was a frigate, towering over most of the dock. This frigate had been painted a jet black, giving it a very ominous appearance. Along both sides of the ship, around twenty cannons were on each side, as well as eight cannons at the back and front of the ship. Painted on the sail, as well as on a couple smaller flags, there was a symbol of a skull and crossbones, only it was covered by a black, ninja style facemask, leaving only the eyes and swords visible.

If Luffy, Zoro, Nami, and Usopp weren't careful, they would run into a large group of pirates on the island…

"Yahoo! We're moving now!" Luffy yelled as he looked out at the sea ahead of them. After waiting for about thirty minutes, the wind had finally picked up again, causing the ship they had to begin moving once more. As Luffy stared out at the sea ahead of them, Usopp had climbed to the look out post atop the main sail, looking at the sea through a periscope.

"Hey guys! It looks like there's an island up ahead!" Usopp called down from his position. This cause Nami to look up from the magazine she was reading, before quickly setting the magazine down and standing up. "Hm, the only island around here should be a small island called Sun Set Island." Nami said as she looked out ahead of the ship at the landmass beginning to form in the distance.

"Hey, what's all the noise for?" Zoro asked as he walked up behind Nami and Luffy, rubbing his eyes at the same time. "There's an island up ahead. I wonder if they have any meat?" Luffy said, absent mindedly rubbing his stomach at the thought of having some good food.

"Uh, guys it looks like there's a pirate frigate docked at the island, and I can see smoke coming from somewhere on the island." Usopp called down, causing the other three teens to take a closer look at the island. "Eh, it looks like the island is under attack by the pirates. What do you want to do caption?" Zoro said, somewhat sarcastically saying the caption part, while looking at Luffy.

"Hm…lets go check out what's going on!" Luffy yelled, a huge smile on his face. "Are you insane? That pirate ship could be carrying hundreds of pirates, and we don't even know who they are!" Nami yelled, shocked that Luffy would want to charge right into an island that was under attack by a large group of pirates. The only reply Nami got from Luffy was said straw hat wearing teen to give her a huge grin.

So much for avoiding the pirates…

"Hey, that's a pretty big pirate ship. I wonder if we'll have one like that some day?" Luffy said as he looked up at the ship from his spot on the beach. As Luffy stared up at the pirate ship, Zoro, Nami, and Usopp were all standing behind Luffy, double checking to see if anyone was going to suddenly attack. As Zoro kept a hand on the white katana, Usopp had reached into the pouch/bag on his hip and pulled out what looked to be a slingshot.

"Hey Luffy, are you sure it's a good idea to be on this island?" Nami asked as she watched Luffy begin to walk towards the smoke rising up over the trees. "Y-yeah, I mean, if there are a lot of pirates here, we may not be able to handle them all." Usopp added, trying to hide the fact that his legs were shaking. "Ah, we'll be fine. Now, lets see if we can find some place to get some meat." Luffy said, completely ignoring the fact the island was under attack.

"Keep quit. It looks like there's something up ahead." Zoro hissed, causing the other three teens to stop talking. As the four teens started to creep closer, they could finally see what was happening. Up ahead, the group could see a large gathering of, what they assumed to be, pirates. They could only assume it was the pirates, because every "pirate" they saw, was dressed like a ninja; complete with mask, throwing stars, and short swords.

Looking closer, Luffy, Zoro, Nami, and Usopp could see that another large group of people, most likely the people that lived on the island, had been gather up into a large group, and tied up. Also, tied to a large poll in the ground, the group of four could make out another figure, clearly male.

The person was, as before stated, was clearly a male, appearing to be around the age of 23. The man had long white hair coming down to the middle of his back, and aquamarine eyes. The man was wearing a pair of black pants, a matching black muscle shirt, and a long black jacket that fell down to his ankles. From what they could see, the white haired man seemed to stand at about 6'4. Also, on his head was a black "Jack Sparrow" style hat.

Standing in front of the white haired man, there was a much older man, most likely the caption of the ninja/pirate group. The older man looked to be about 41, with short gray hair barley visible from the facemask he wore. Unlike all the other ninja's around, this man wore a red vest. Also, two katana's hung from his waist, rather then a short sword.

"So tell me, why did you attack my men?" The older man spoke up, glaring at the white haired man. "Did you really think you could defeat the great captain Zen's ninja pirates?" The older man, Zen continued. The white haired man gave a small laugh, before giving a reply. "Well…your men are really a pain in the ass. Plus, they just pissed me off when they started burring houses down."

The answer seemed to tick off the pirate captain, because he drew one of his katana's and held it under the white haired man's neck. "Care to tell me your name before you die?" The captain said with a slight smirk on his face, ready to thrust his blade into the white haired man's neck. "My name? It's Riku Kenpachi." The white haired man, Riku said.

"Captain, intruders!" One of the ninja's yelled as he threw a ninja star at the group of bushes that Luffy, Zoro, Nami, and Usopp were hiding in. As the blade flew towards the four teens, Zoro quickly drew his white katana, slashing the throwing star and knocking it off cores. "State your reason for being here, and your names, or you won't live to see tomorrow." Zen spoke up, as several of the nameless ninja's surrounded Luffy and his friends.

"I'm Luffy D. Monkey. We stopped here to see if we could find some place to eat." Luffy said, not bothered at all by all the ninja's surrounding him and his friends. "But, I can't let you execute that man." Luffy continued, suddenly becoming very serous. That last statement caused most of the ninja/pirates to laugh a little, before captain Zen spoke up again. "And how are you going to stop us, straw hat?"

Luffy then broke out into a huge grin, as Zoro also started to smirk. Placing the white katana in his mouth, blade facing his left side, Zoro then drew his other two blades, holding one in each hand. As several ninja's charged at Zoro, he held all three blades ready.

"Oni-Giri." Zoro said with a little difficulty, due to the fact a sword was in his mouth. As the ninja's came closer, Zoro lashed out with a lightning fast attack, swinging the swords in his hands in an "x" shape slash, while moving his head slightly so the blade in his mouth would slash the ninja's at shoulder level.

As the ninja's that had lunged at Zoro fell back, at lest one slash on each of them, another group lunged at Luffy. As Luffy took off screaming, the ninja's followed him a little ways through the forest area they were in. However, as Luffy ran by a random tree, he grabbed onto it, and kept running. And his arm kept stretching…and stretching…and stretching. As the ninja's stopped and stared at Luffy's arm in shock, since it was now almost thirty feet long, Luffy turned around and smiled. "Just kidding. Gomu-Gomu no Rocket!"

As soon as that was out of his mouth, Luffy suddenly shot forwards, his arm pulling him back towards the group of ninja's chasing him. As Luffy slammed into the ninja's, they all went flying in different directions. "Men! That straw hat must have the power of a Devil's Fruit!" Zen yelled, seeing Luffy's arm return to its normal size.

"Yup, I ate the rubber fruit." Luffy said, grin still on his face. Hearing this, some of the ninja/pirates backed up a little, not knowing how to battle someone who had eaten a Devil's Fruit. "Alright men, keep your distance with the straw hat. Attack from long rang!" The ninja captain yelled out, causing most other ninja's to fall back a ways.

"Hey Usopp, think you can give us some cover?" Zoro asked the long nose friend. "Of course I can. Namari Boshi!" Usopp yelled as he pulled a handful of ball bearings out of his bag, and began launching them at several ninja's, hitting the ninja's in either the head or the chest. As soon as the ninja's were distracted by Usopp's attack, Zoro and Luffy rushed forwards, taking the fight close range.

"Hurry up and kill them!" The captain yelled, before turning back towards Riku, and finally thrusting his katana at the white haired man's chest. Only, Zen's smirk quickly turned into a shocked expression, when Riku's arms suddenly came from behind the poll he was tied to, tearing through the rope, and slammed each fist into the flat side of the katana, stopping it dead in its tracks.

"Gomu-Gomu no pistol!" Luffy yelled as he threw his right arm forwards in a punch, only to have it keep stretching, smashing into Zen's face while Luffy was still about twenty feet away. As the captain went flying, Riku dashed at a group of ninja's, delivering a powerful series of punches into the bulk of the ninjas. As Riku proceeded to beat the snot out of the ninjas he was attacking, Zoro ran forwards towards a larger group of ninjas, attacking with another Oni-Giri, causing a large number of ninjas to fall back, wounded.

As Usopp fired another ball bearing from his slingshot, a random nameless ninja had snuck up behind him and Nami. However, as the ninja lunged at the two teens, Nami noticed something wrong and turned around. Quickly reaching down into a small holster kept just under her skirt, Nami quickly pulled out what looked like three wooden sticks. However, in one quick moment, Nami had thrown one piece into the air, while slamming the other two onto the ends of the piece in the air, causing the three parts to connect into one long wooden staff.

Spinning the staff in one quick movement, Nami slammed said weapon into the ninja's head, stopping him dead in his tracks. Giving a small smile at the fact she had beaten a ninja/pirate, Nami turned back to see how the others were doing, but soon noticed that a group of about seven ninjas had surrounded both her and Usopp. "Hey guys, a little help here!" Nami yelled to Luffy and Zoro, knowing that she wouldn't be able to handle large numbers of people in battle by herself.

With Luffy currently attacking the ninja/pirate captain, and Zoro attacking the main bulk of the ninjas, Riku was the one who responded to Nami's call for help. Moving up behind the first ninja, Riku launched a devastating punch with his right hand, landing in the middle of the ninja's back. As the first ninja was sent to the ground, another turned around and lunged with his short sword at Riku. Steeping to the side, Riku let the sword go past him, before grabbing the ninja's arms with his left hand, while slamming his right fist into the ninja's face.

As the five other ninjas fell back a ways, Riku noticed that more ninjas had started coming from the beach, most likely from another ship that had just landed. It was clear that this was going to take a while…

"Gomu-Gomu no bazooka!" Luffy yelled as he threw both of his arms backwards, each stretching from about twenty feet, before shooting back towards Zen. As Luffy's hands hit Zen's chest open palmed, it sent the ninja/pirate flying off into the distance; where he would land, no one knew. As the captain went fly off to who knows where, the last of the nameless pirates were beaten, Zoro's sword landing the final blow. As Luffy and Zoro made their way back over to Nami and Usopp, Riku made his way over to the town's people, and started untying them.

"Hey white haired dude! That was some awesome fighting you did back there." Luffy said as he, after having made sure Usopp, Nami, and Zoro were uninjured, walked up behind Riku. "There is one thing I would like to know: do you guys have some place where I can eat some meat?"

After getting over the shock of being captured by pirates, and then being saved by five young adults/teens, the town's people had invited all five for a sort of "thank you for saving our lives" dinner. As the five young adults sat around a small table, they had started talking.

"Let me get this straight; the four of you are planning to go to the Grand Line, all alone?" Riku asked, not believing what he was hearing. "Don't be silly! We still need a musician; plus there are five of us counting you." Luffy said, before finishing his 12th plate of food. "Hold on a second! Who said I was coming with you?" Riku asked in a middle state of shock as he stared at Luffy.

"Yup, I've decided that I want you in my pirate crew." Luffy said, acting like it was an everyday thing, as he placed another helping of food on his plate. "It's not really you chose if I join you pirate group…" Riku muttered under his breath as he watched Luffy start shoveling food into his mouth. "Take it from us, once Luffy decides that you should be in his pirate group, he'll stop at nothing to make sure you join him." Nami said, motioning to Zoro and herself, shaking her head slightly.

After thinking things through for a couple minutes, Riku's eyes light up when an idea struck him. "Hey Luffy, how about this: You and I have a sparing match; if you win I join you pirate crew, if I win you drop the subject of me becoming a pirate?" Riku said, a slight smile on his face. After swallowing the huge amount of food in his mouth, Luffy's face broke into a grin. "Alright, it's a deal. But I'm warning you, I won't lose."

"Right, so you two fight like you normally would. First one to either pass out, or give up is the loser." Nami said as she looked between Riku and Luffy, as the two stared each other down from across the small clearing they were in. As Luffy cracked his knuckles, Riku stretched his neck out a little, making sure everything was good to go. "Alright, on your make, get set, go beat each other senseless!" Nami yelled, signaling Riku and Luffy to start the fight.

"Gomu-Gomu no Pistol!" Luffy yelled as he threw his right arm towards Riku, it stretching out to hit him from a distance. As the fist came zooming towards him, Riku simple side steeped, letting the arm go flying past him. However, once the arm flew past him, it grabbed onto a near by tree, holding firmly. "And Gomu-Gomu no rocket!" Luffy yelled as he used his out stretched arm to pull himself towards Riku at a high rate of speed.

Despite the fact that Luffy was flying towards him at a high rate of speed, all Riku did in response to Luffy's attack was cross his arms in front of his chest. "Got 'ya!" Luffy yelled before crashing into Riku. However, unlike before, Riku didn't go flying backwards. In fact, all Riku did was slide back about three feet, before coming to a complete stop once again. Also, Luffy found that his face was now really sore.

As Luffy fell back a little ways to recover from his attack, he noticed something about Riku; he hadn't reacted to the attack at all. In fact, from what Luffy could tell, the attack hadn't hurt Riku at all. "Your not the only person to ever eat a Devil's Fruit you know. There are fighting styles that can combat the power of a Devil's Fruit, when used the right way. And if someone has also eaten a Devil's Fruit, then those styles work even better." Riku said with a slight smirk.

Hearing what Riku had just said, Luffy broke into an even bigger grin. "It looks like this will be harder then I thought. Oh well; Gomu-Gomu no bazooka!" Luffy yelled as he threw both hands backwards, before thrusting them at Riku. However, as the attack came flying towards Riku, said white haired man raised both of his hands, giving Luffy a blank stare as the attack came zooming towards him.

As soon as Luffy's hands hit Riku's, Riku quickly closed his hands in a tight grip, catching Luffy's hands in it. However, instead of trying to crush Luffy's hands, he quickly yanked on Luffy's arms in stead, causing the straw hat wearing pirate to come flying towards him. As Luffy came flying closer, Riku dropped Luffy's arms, and raised both of his own up over his head. Then, when Luffy was right in front of him, Riku brought both hands down on Luffy's head, slamming him into the ground.

As Luffy rolled to the side to put some distance between him and Riku, he slowly made his way back to his feet. "Gomu-Gomu no whip!" Luffy screamed as he thrust his right leg out to the side, causing it to stretch out, before quickly spinning in the opposite direction, causing it to go flying at Riku. However, Riku once again caught the attack with his ice arms, before spinning around, bringing Luffy's leg up over his head, and snapping it down at the ground, bringing Luffy with it.

"He really should have seen that coming…" Nami said, as she, Zoro, and Usopp winced when Luffy slammed into the ground. As Luffy stood back up, moving very slowly, he slowly raised his fists for another attack. "Gomu-Gomu no gattling gun!" Luffy yelled as he began rapidly launching quick punches at Riku, moving so fast it gave the illusion that he had multiple arms. As the fists started pounding into Riku, said white haired man noticed that, while the fists were moving at a very high speed, they were rather weak compared to an attack like the Gomu-Gomu no pistol.

After a minute of the rapid punch attack hitting him, Riku finally grew tired of the attack, and, after a couple failed attempts, was able to catch one of Luffy's arms in his left hand. "Not again!" Luffy yelled as Riku quickly yanked on his arm, causing the straw hat pirate to come flying at Riku once again. "Deep impact." Riku said in a calm voice when Luffy was right in front of him. Taking his right arm, Riku smashed it into Luffy's face, hitting with such a force that it caused Luffy's neck to stretch out about ten feet, before his body was pulled along to catch up.

Riku gave a slight sight when Luffy crashed into a tree, before sinking to the ground. As Riku walked over to Luffy, he made sure that his hate was still in place, before finally going to check on the younger male. As Riku got closer to Luffy, he noticed that the younger teen was starting to stir a little bit. "Did I win?" Luffy asked in a drowsy voice, still recovering from being hit so hard in the head.

Riku took a deep breath, before answering Luffy's question with a slight smirk on his face. "Yeah, you won. Right before I hit you, you somehow managed to kick me in the head. It knocked me out cold." Riku said, trying to hold back a laugh. Hearing what Riku said, Nami, Usopp, and Zoro exchanged looks, but didn't say anything when Luffy jumped up off the ground. "Yahoo! That means that your now part of my pirate crew. Alright, we got another member to our crew; next stop Grand Line!"

END

Ug, I don't really like how this turned out, being I had to make everything up to find a way from Riku to meet Luffy and co. but it will have to do. Now that this is done, I can start writing chapters on the main storyline, such as the Sanji introduction arc, which will be next. Note: I didn't say what Devil's Fruit Riku had eaten, that way it can be a surprize in the big fight coming up...
