One Piece: The Power System

Rein landed in the mountains unnoticed and quietly made his way back to the Bandits house. Rein wouldn't be surprised if everyone was asleep at the moment since it was kinda late. Just in case, Rein snuck into the house quietly, his ability to sneak had improved over the years. Ace had a couple of tricks that he had shown him, though Ace preferred to beat people then steal their treasures instead of outright robbing people.

Once Rein was in, he looked into the storage room that had no one in it, they were gone. Rein silently left again and went to his treehouse. And there they were, they had both fallen asleep in the treehouse they had made years ago. Rein switched his clothes out for pajamas Makino had made for him and went to sleep soon after changing.

The very next day, Erica was the first to wake up. When she saw Rein across the room inside his quilt fast asleep, she smiled. She got up and began to make breakfast for the two pigs, she had to make much more since Luffy ate the most of the two!

Eventually, Rein was next to wake up, he had caught the scent of food being made. When he looked over in the small area, Erica was making something with vegetables in it. Luffy was still asleep and snoring at that, so Rein threw his quilt over his face.

Rein walked over to the table and took a seat where Erica was cooking. Rein had to say, her cooking had improved a lot but he didn't want her as the chef of his crew. That would go to someone else he already had in mind.

"Ah, you're up, where were you yesterday? Me and Luffy waited for you for about 2 hours before we started to eat without you." Erica turned back, she thought Luffy was the one who woke up but saw that it was Rein. The big difference between the two was that Luffy had a scar underneath his left eye. He had done this to prove that he was tough in front of Shanks that day.

"Just an important run to earn some money, it was nothing special but it will benefit us in the future." Rein said casually: "Say, would you like to change your Devil Fruit ability to something much stronger and even better for cooking?" Rein stretched his arms then used his hand to hold his head on the table.

"A stronger power?" Erica was stunned a bit and looked at Rein. "A power greater than the one I have, it does sound good but I heard that you can't consume any more Devil fruits or else." Erica somehow found out about some Devil Fruit facts from reading some book.

"This is true but I have a way to extract your Devil Fruit and to give you a much better one. The attack power on this Devil fruit is devastating. Your Devil Fruit is good for utility and Defense, basically a defense type." Rein smiled and sat up.

"This... Hmm, Okay, I'll do it, the more power the better if I can be of use and help you and my friends in need." Erica agreed seriously until she saw black smoke coming from the cooking stove!

"Ah! No!" The food had burned because she was distracted talking with Rein.

"Oh, shoot, my bad!" Erica shook her head and threw the meat out to replace it with a new fresh one.

"What about you? Don't you want a power as well?' Erica seasoned the meat and asked.

"I already have one but don't tell Luffy, he'll find out later." Rein wanted to see Luffy's surprise when they met again. Ace had surprisingly gotten his power on his adventure, he wanted to be mysterious to, LOL!

"What? You have a power! When did you get one?" Erica was now shocked, did he get a power last night when he was out. If so, then it made perfect sense that he was out so late.

Hehe, well.." Rein smiled with a twitchy mouth, she would be blown away if she knew he had powers since 7 years ago!

"I had them for 7 years!"

"For f.u.c.k sake!" Erica Cursed then put her hand over her mouth after spitting profanity. Erica looked at Rein deeply, he had a power all this time and she didn't know it! "Rein, why so secretive, you know you can tell me anything and I won't turn against you." Erica stared into Rein's eyes which caused him to look away.

"I was going to tell you but I forgot, but you know now and you're the first person I've told, hehe!" Erica thought about it and nodded with a smile, it was like she had forgotten all about it. Soon, Luffy woke up and rushed over yelling meat.

"Luffy, you slept for a while, huh?" Rein patted Luffy's back as he spoke.

"I ate so much yesterday and I sparred with Erica a few times."

"Wow, how did that g.." Before he could finish....

"I lost!" Luffy immediately said after, this was a sure thing with her being intangible and all.

"Understandable, but don't worry, you'll soon be able to hit people like her in the future." The food was finally done and served to everyone. They all ate like pigs, including Erica, who had grown used to Ace, Rein and Luffy's way of eating.

Once they were done, Luffy went outside but Rein halted Erica, she had something else to do! Rein stopped her and called her to a secluded spot. He then took out the Devil Fruit extraction incubator, it looked like a pokemon go egg incubator but with a vacuum hose attached to it that went around someone's c.h.e.s.t like a doctor Octavius claw.

"Attach this to your c.h.e.s.t, this will suck your devil fruit out, it will take 2 hours to complete. Once it is done, the devil fruit will appear in the incubator." Rein said, "Make sure you take out all the storage you have in your body, I will later give you something for storage later." Erica stood in place staring at the device with a strange look on her face but nevertheless, she complied.

"Here, take this, Once your previous devil is out of you, eat this Devil Fruit!" Rein pulled out the Black Flare-Flare Fruit that he had put in mini treasure chess as Shanks did with the Gomu-Gomu Fruit. Shanks had robbed that fruit from what he said to be his "enemy" before coming to the east blue.

Erica stared at the fruit that glowed black for a second before reverting to a normal black fruit. The fruit had fiery black color to it with black flame designs just like the Regular Flare-Flare Fruit, she was mesmerized by its beauty!

"I-I understand!" Erica was secretly excited, she didn't know what power she would gain but she had a clue that it might be related to fire in some way, which she couldn't be any more right about. Rein nodded and left the house to catch up with Luffy who was actually waiting outside.

Luffy and Rein went to Mikino's house, he told her that he was going to set out at sixteen. Makino wasn't surprised to hear this but she felt sad just like how she felt when Ace left. All these years, they all had grown on her. Makino told Rein Luffy and Erica who wasn't present to come by for dinner.

Rein told everyone in town, so they would know when the time came, he also dropped by Gyaru's shop to tell him to build him a sturdy boat for that year. Of course, he made sure to tell them to keep it a secret from Garp, that would be a pain if he found out!

Rein made his way to the sea area where he first caught his first fish with Luffy. They both went fishing and surprisingly caught a huge crab! Rein killed it and put it into his storage for later at Makino's dinner. They eventually caught more fish for later feeding, time passed and they both left their fishing spot to head to the bandit's house. Rein had lived like this for all of his life on this island, how could Luffy stand being on this island all alone with no company?

Rein gave the bandits some fish by dumping them into the place, only to leave soon after. This caused Dadan to yell at Rein, but he had already left with Luffy before he could hear her. A fish had tail whipped her in the face so she couldn't talk in time.

At this point in time, three hours had already passed so Rein and Luffy headed back to the treehouse to check in on Erica. Since so much time had already passed, Rein was sure she had already eaten the Devil Fruit.

Once Luffy and Rein walked in, they saw Erica sitting alone with an incubator beside her. Inside the incubator was a Brown Devil Fruit with Cloud-like swirls on it. This was clearly the Devil fruit he had given her in their younger days!

The Swamp-Swamp Fruit!

Erica looked up and a gleam of light flashed in her eyes, her eyes were pitch black!

"Uh, did you consume it already?" Rein walked over and picked the incubator up that was clearly holding Devil Fruit in it.

"Yes, this fruit is so amazing!"

Erica suddenly smiled when he asked his question. The Devil fruit was way better than the one she previously had, it had so much potential compared to the one she had before. Luffy looked confused and looked at the fruit in the incubator.

"Eh! That's a Devil Fruit isn't it!?" Luffy pointed at the incubator in Rein's hand but he was really pointing at the fruit.

"Oh, yeah, it is, she found it but I'll be taking it for myself, haha!" Rein wasted no time and put the fruit into his storage for later. Luffy wasn't an idiot, he knew he couldn't eat another Devil Fruit or he would suffer for it. Rein didn't have a Devil Fruit ability so he thought Rein would consume it for himself later.

"Erica, let's go outside to test your Devil fruit ability!"

Erica nodded fast like a chicken pecking at some grain and stood up. She was the fastest to arrive outside, she was also the most excited, obviously! Luffy looked confused, test her devil fruit ability, what is there to know?

Once they were outside, Rein and Luffy stood some way away to avoid what was to come. Suddenly, a black flame shot toward the lake, it hit the water and caused it to burst upward into the sky. Luffy's mouth hung wide open and his eyes bulged out of his skull like eggs, how could her fruit develop fire, wasn't it mud!?

"Goodness, the power of this fruit is crazy, she could make her own crew with such power!" Rein shook his head, this power was highly life-threatening if anyone were to be hit by it. Luffy was stupified for a long time, before coming to himself.

The group decided to just spend their time at Makino's house to wait for dinner. Time passed and they eventually enjoyed their dinner with Makino. Rein was sure to pull out some fish and the big crab he and Luffy caught.

Rein mostly relaxed for these years gone by, before he knew it, 2 years had come to past. Today was the day that he and Erica left on their journey out into the world of one piece! The boat Gyaru prepared was ready to go, they had thrown a party 2 days before Rein's day of leave. Rein wasn't sure if he would have been able to wake up from the hangover.

Author Note: LOL so sudden xD

Erica was the first to jump into the boat, Rein Hugged Makino, he wanted to hug Dadan but she wasn't here. Funny thing is, she did the same thing to Ace but when she heard Ace's final message to her, saying "thank you for taking care of me" she broke down and started crying immediately.

Rein looked at the short bandit and gave him the gift to give to Dadan. He also said to tell Dadan the same thing as Ace told her before he left. Dadan always had dreams of being beautiful and slim, so as a gift he gave her the Slip-Slip Fruit. We already know what this fruit would do to someone if they consumed it. This fruit wouldn't block Alvida from getting hers in the future since this came from the system.

Rein gave Luffy the last handshake and a brotherly hug before jumping into the boat with Erica.

"See ya, everyone, we'll meet again Luffy!" Rein continued to wave at everyone onshore, as did Erica until they could see them no more.

It had finally begun!
