One Piece: The Power System

"Ready up!"

Kuina held the Katana in her, the dazzling gleam from the sword was blinding. She stared at Rein who was acting nonchalant and her will grew stronger. "Remember, you were the one who chose not to use a sword but rather your hands!" Kuina tightened her grip on the Katana.

Rein didn't say anything and just stared her in the eye as to analyze her.

"Fight!"

Upon hearing her dad give the go for battle, she rushed Rein with her katana and stabbed forward, her aim, his shoulder. She was surprisingly fast but not nearly as fast as Rein, he simply dodged her attack. Kuina didn't give up and started jabbing her sword faster but they were still dodged every time.

Kuina backed away while taking heavy breaths. "You're able to dodge pretty well, but don't think it's over!" Kuina closed her eyes, it seemed like she was focusing as a strange blue glow appeared on her sword.

"Dodge this! Whirling Slash!" Two blue slashes shot out from her sword, this was apparently her ultimate attack.

The blue slashes slammed towards Rein! Erica was stunned seeing Kuina attack, she didn't know swordsmen could develop to such a degree. However, right before the slashes could hit Rein, they were both grabbed by him. Koushirou and Erica backed away due to the wind getting in their eyes and the blue blinding light.

"What!? No way!" Kuina attack shattered like glass under Rein's grip as it was completely dispersed. Kuina was visibly exhausted after the attack and couldn't fight anymore, Rein had won by playing defense.

After the battle Kuina felt dispirited, she knew that her attack would burn her stamina but she was counting on it to at least stun Rein. "Your stamina doesn't fit well with your body but since you're part of my crew now, I'll show you the path." Rein patted her shoulders, he always felt that Kuina was never explored enough and deserved so much more.

Kuina sighed and looked at Rein "Okay, if I can get stronger and become the strongest swordsman to face Zoro one day then I'm up for it." Kuina stood up and put her long hair into a ponytail as Rein looked over at Erica.

"I think it's about time for you as well, I've been having you train in Rokushiki but now you need to learn Haki!" Rein pulled out an Armament Haki manual from his system, he didn't have an observation Haki manual so he would get one at a later date.

Erica took the manual, she had been given many other manuals before by Rein. Over the years she had trained in some Rokushiki techniques so she was willing to know more about fighting styles since she favorited it the most.

"This Haki, is it better than the Rokushiki ones you gave me?" Erica wondered if there could be anything better than Rokushiki because she found these techniques to be so convenient.

"Oh, it's much better, trust me, you're going to need to learn this or you won't survive in this world!" Erica was surprised and so was Kuina who was off to the side, what was so good about this Haki?

"Mr. Koushirou, I hope you don't mind us staying for about a week or so. I want you to catch up with your daughter before we leave. She also needs to learn a couple of things before we leave this place." Hearing what Rein said, Koushirou sighed lightly but saw no problem with it, his daughter would leave but he knew she was going to get stronger. Rein had this confident vibe about him that Koushirou had faith in.

"This is naturally not a problem, if she can get stronger I'm sure that it wouldn't pose a hassle at all. I'll take you to the residence next door to my residence for you guys to stay. We have many students but all of them are grown men." Koushirou signaled Erica Rein, and Kuina to follow him.

As they were walking, Rein spoke to Erica "Give Kuina the Soru manual to learn, you can hold on to the Haki Manual to learn for yourself for the time being." Kuina wasn't even strong enough to learn Haki yet, he would have to buy a few things from the system to improve her faster.

"Okay, I'll give it to her afterward." Rein gave Kuina his mask to hide her face for many reasons. Once they were outside they caught the attention of anyone who was nearby. Rein was content with building his crew from the ground up, so it didn't matter to him.

"Hmm, wasn't there two in the Master's residence, why is there another woman?" One man watching from the distance asked.

"I don't know, it none of our business, maybe we didn't see her come when we went somewhere else at that time." Another man didn't think too much about it

Kuina looked around and found a few changes over the years during the time she had been away. The residence was right next door so they made it there in a flash. "There are four bedrooms in this place, you can choose which room you would like to sleep in." Koushirou looked at Kuina, this meant her as well.

"Kuina, come talk to me later or tomorrow, I want to spend some time with you for a bit." Koushirou's face seemed to have grown a bit younger as he smiled brightly.

"Of course, father, though it seemed like a night's sleep to me, I will come to see you." Kuina bowed to her father before he left. Once they were done, they chose their rooms and Rein called Kuina and Erica to the room not chosen by anyone.

"Erica, hand it over to her." Erica said nothing and handed the Soru Manual to Kuina who took it without hesitation. "This will increase your speed in bursts or for a longer duration, you need to work on your arms, legs and body for this weeks time. I have a way to speed your training up, so you don't have to worry about missing out, hehe!" Rein took out the weight suit and the last three Energy Pills.

Rein thought about it for a bit and decided to sell the Aura-Aura Fruit which sold for 350,000 System Points! "First things first, you're going to wear this weight suit and swing your sword 500 to 1000 times a day. You will also work on your legs which Erica here will help instruct you on." Rein gave Erica the Weight Crystals for the suit and also a bit of body strengthening pills for her arms and legs.

Rein was still sleepy from the time Erica woke him up so he decided to go to sleep.

Myriad Island

This huge island was at the edge of the calm belt where many sea kings dwelled. At this time, a fight broke out between some pirate groups. This happened all over the island but there were special pirates who were stronger than the norm. "Well, well, if it isn't Captain Cloud, you've come to the wrong side of this island, my crew will be controlling this territory for the time being!" The man by the name of Baron glared at Cloud and spoke with authority.

Baron wore Black Armor with a huge Battle-Axe on his back, he had black eyes and hair. Baron stood around 6,11 to 7,0 in height.

"Haha, Captain Baron of the Berserker Pirates! I don't see your name anywhere on this island! It's best if you let us pass or things are gonna get worse for you and your crew!" Cloud's words were pretty threatening as he said the word worse as if Baron meeting him here was bad enough.

"Ha! Just as arrogant as always, remember, you said it and not me!" Baron moved swiftly to attack Cloud by punching toward Cloud. For his size, he was pretty fast on his feet!

BooM!

His fist connected and smashed the ground as it collapsed. Baron punched hard and many people nearby moved away as to not get caught in the feud of their captains.

"Not bad, but it isn't enough!" Cloud was completely unharmed from the attack!

"Oh, yeah, you're a Devil Fruit user, the Cloud-Cloud Fruit!" Baron was annoyed and continued "I hate these ability users the most, always thinking that they're top dog!" Baron backed off but Cloud only smiled.

"But, I know how to take down ability users like you!" Just when Baron was about to attack again, Cloud interrupted him.

"Fog Stream!" Fog shot out of Cloud's body instantaneously and covered the area around him. Baron still smashed his fist towards Cloud but connected with nothing. The wind alone from his punch blew most of the fog away.

"Sadly, I don't have time to play with you Baron, so I'll be taking my leave for now!" Cloud sneered and disappeared with his men in a flash!

"That cowardly bastard! He talked all that trash only to run away!" Baron ridiculed but what he heard next angered him nearly to death.

"Sir, someone has stolen the treasure we've collected from that ruin we explored yesterday! I think it was the White Cloud pirates, they were playing us along only to steal from us!" The man who was one of Baron's crewmates hurriedly and spoke when he noticed that the treasure bags had been taken somehow.

"F.U.C.K! Cloud that bastard, I'll break him if it's the last thing I do!" Baron's eyes turned bright red as some strange red Aura began to flow over his body.

"Sir, calm down, we'll get them later!" The swordsman of the crew by the name Saiga spoke after seeing his captain nearly going berserk. This was also because he had a Devil Fruit that could allow him to go berserk like this!

Baron breathed deeply and calmed soon afterward. "Let's find those thieves, I'll beat that girly-boy black and blue when I catch him!" Baron gritted his teeth and commanded his crew members. His crew members fanned out to begin their search.

Meanwhile, Cloud and his crew appeared near a mountain. "That meathead only thinks with his muscles, I wonder if he even has a brain? Ahaha!" This was the sniper of Cloud's crew by the name of Neal laughed in delight, they had fooled this guy before so this was nothing new to them.

"Don't underestimate him! He may be an idiot to some degree but in an all-out fight, I'm not confident in my victory." Cloud felt like he was no match for Baron, he had raw strength and could use some ability to hurt him even though he was intangible.

Everyone grew silent hearing Cloud's statement, they knew the raw power of Baron but only could talk about his intelligence. "We're only here to find the gold mine that was supposedly on this island, I hear that there are even Devil Fruits that may be in that secret ruin but the location is unknown." Cloud touched his chin as he spoke to himself.

"I've heard some news recently that the Flagstar Pirates have found some strange insignia that appears to be part of some puzzle." One of the men decided to speak during the brief silence.

Cloud turned around and looked at his crew member who was the chef of the crew. "Oh, tell me more, what did it look like?" Cloud immediately took an interest and asked. They have been on this island for about 5 days now so they weren't up to date on anything.

"Well, it must be important if the Malone family and Red River Pirate Alliance are hunting him. The insignia had a snake on it, that is all I know." The chef squeezed out the bit of words he honestly didn't want to tell his captain.

"What!? It must be for some puzzle for sure, maybe to a secret Ruin or something!" Cloud smiled and said "Hoho, we'll have to hunt the Flagstar pirates down first, where were they last seen?" Cloud smiled deeply, he wouldn't miss a chance to annoy the Red River Pirate Alliance! They were working for someone who hid in the dark, thus they were here on his order.

Cloud didn't know who their leader was but he never showed his face or showed off to anyone, he was really secretive. He never appeared but he had someone manage the Alliance to get what he wanted. His main focus is currently Devil Fruits!

"We're in the South but he was last seen in the North part of this Island and we know what creature hides there." This is why the chef didn't want to tell his captain anything because his captain loved trouble the most and would jump to start corruption if he found and saw an opportunity.

"Hmm, If I remember correctly, there was huge Yeti in the north part of this Island, it is mostly snowing there." The Island had four terrains in each part of it. The North is where it snowed all year round and as for the south where they're currently at, it was grassy and full of mountains.

"Alright, let's head to the North, we'll rain on their parade and take the insignia for ourselves!" Cloud smiled and touched his chin thoughtfully. Some of his crew members sighed but didn't disagree with their captain's command.

Somewhere in the west part of Myriad Island, there was a base near the shore.

In this base was a man in a burgundy and black suit, he had a full clean beard and long black hair. His features could be called handsome if anyone were to lay their eyes on him.

The man had red pupils, he had a glass of wine in his hand at the moment as he was speaking to the man in front of him with a frown. "Are you telling me you lost the Flagstar pirates!? Didn't news just recently say that you guys had cornered them!?" Rage could be visibly seen in his eyes as cracks appeared on his glass of wine.

"Boss Vladimir, we had cornered them but something had happened, they suddenly disappeared when we arrived at their cornered position!" The man hurriedly and explained in fear that he would be slaughtered on the spot.

Vladimir glared at the man but smiled soon after. "Is there anything good you can tell me? How is the battle in the north against that Giant Yeti, has Red Bull taken it down yet?" Vlad took a sip of his wine and asked.

"Well, this Yeti is stronger than we thought, it can even regenerate its wounds, it won't be easy to take down." The man started to sweat, "But we know for a fact that it is guarding something special within the cave it dwells in!" The man wiped the sweat off his forehead with a rag as he spoke, he was extremely nervous.

"So you came to report to me with nothing good but only bad things?" Vladimir stood up slowly with a smile that wasn't a smile. The man was horrified seeing Vlad standing up and stood up himself.

"Can you tell me anything good about what has been going on with our current situation? You know my boss is expecting some results and want me to return some goods to him before the end of the month!" Vladimir's expression changed from a smile to a cold grin.

"Uh?" The man was in a dilemma, he had nothing good to report, this was why he didn't want to report in the first place but he was forced to do this by a certain someone.

"I.." Before he could finish, he was stabbed in the heart, his eyes dilated as they turned dark, he died! The man was stabbed by a red weapon that was dark red in color. It was a weapon that Vlad had formed.

"Well, he died with no good news, what a shame!" Out of nowhere, a man appeared out of the shadows, he was around 5,8 and was very slim, on his back were two bat-like wings. "But I suppose the ability to control blood is pretty strong and hard to resist, even if it's only a Paramecia Class!" The man grinned and nodded thoughtfully.

"Miguel, you and your Nightgale pirates need to assist the Red Bull pirates up north," Vladimir said,

"Also, send more people to search the north, the Flagstar pirates couldn't have gone far, we've destroyed their ship so there is nowhere for them to run." Vlad smoothly spoke his intentions, he knew that the Flagstar pirates couldn't run with so many people hunting them and with the fact that they had no means of escape, it was only a matter of time! Sadly, Vladimir didn't have time to burn, so he needed them found fast.

"Hehe, got it, boss!" Miguel replied in a sarcastic manner. "What about your Blood Incursion Pirates? Will they help in this assault?" Miguel knew that Vladimir's position was higher in the boss' eyes and wondered if he would send his crew to assist.

"My crew will stay here at this base until further orders from the boss, so go help RedBull!" Vladimir was always annoyed by Miguel's questions all the time, he just wanted him to shut up and follow orders!

"Tsk!" Miguel did answer and began to walk off.

"Oh, and tell someone to come in here to clean up this mess!" Vladimir took his seat and started going through some papers.

"Damn bastard!" Miguel whispered to himself as he left. Soon after, two men came in to take the dead body away, they did it fast and quietly as to not anger Vladimir!

Moments later, the DenDen Mushi began to go off! The features of the Denden Mushi changed into someone wearing sharp sunglasses and a feathery pink coat on its back! Vladimir picked up the DenDen Mushi with a nervous expression

"Ah! Mr. Joker, boss!"

Author Note: The Red River Pirate Alliance is pretty much 3 pirates crew. The Nightgale Pirates, The RedBull Pirates, and the Blood Incursion pirates. I Just wanted to let you guys know that if you haven't caught on yet.
