1 Chapter 1

Messing with my computed after watching another episode of One Piece I stretch a bit, feeling a bit hungry and thinking of going to eat some good food.

Just as I was about to get up a new pop-up appeared on the screen and I take a look.

Would you like a whole new experience? Come and test out the game of the century.

Later, if anyone asked, I would not be able to say why I bothered but I decided to not just delete this pop up and instead enter it.

Please select the world:

Seeing that I looked over the options. There were several danger Ratings that went from 1 to 11, with more points the higher the rating.

Scoffing at it I play it safe and choose one I understand rather well and would like to play at

World Selected, One Piece world at the Grand Lines (Fishman Island, middle ground between Paradise and New World).

For selection, earns 590 points.

Please select Origin:

Drop-in (sent as you are now. Costs 0 points)

Substitute (replace a character from the world selected, you are also able to generate a new character but that would change the plotline depending on who you select. Costs equal to what the character's tier is.)

Possess (posses the body of a character of the user's discretion from other worlds and then is sent to the world selected. It is a mix of Drop In and Substitute. Costs equal to what the character's tier is.)

Thinking for a bit I understand that this should be some sort of game simulator. It is very detailed, I only hope it isn't full of glitches.

Regardless, I think of my options. This world is one of Physique and Swordsmanship in the end, and between the two I prefer the sword. Now, I know I need a decent start if I intend to get good results and I have the points so I should get someone with enough talent that wouldn't instantly lose in a place like Paradise and that would be a good pick for a swordsman.

... After a bit, I think of someone that would be damn near perfect. His talent for swordsmanship is amongst the best I can think of from the top of my head.

Muichiro Tokito, the Mist Hashira from Demon Slayer.

He is the youngest Hashira, he was able to go from someone who never held a sword to a Hashira, creating a whole new breathing style, in 2 months.

2 MONTHS!

This sort of talent, how many can compare? And if I can adapt his physique to that of One Piece, defeating Mihalk in time won't be a dream or that impossible.

I mean, I would have the slight issue of limited life span thanks to the Demon Slayer Mark, but maybe there is some way to extend the life span? I dunno, guess we can only wait and see.

Anyway, checking the next section I see what else is there.

Please select your perks, items, and talents:

Well, now it is the next stage. Checking the perks and talents I take a good while to select what I want before clicking on the okay.

Body Talent

Cost: 10

You lift. Your body is now in perfect fitness and health, with significant muscle growth, within healthy human standards.

You are immune to further minor illnesses, but not diseases or injuries. All healing or medical operations performed on you will be completely without complications, residual pain, or unwanted scars.

Additionally, you can rapidly learn any non-supernatural athletic skills you encounter: acrobatics, physical sports, parkour, swimming, etc. This is an experience and skill acquisition multiplier, not a flat improvement, and it further scales to the strength and skill of your opponents and trainers: the better they are than you, the faster you learn, until you've caught up to them.

The individual benefits of this Talent may also apply, at your discretion, to any/all of your purchased and captured subjects. Unwanted conditions are erased according to your wants, not theirs.

.

.

Martial Talent

Cost: 10

You fight. You have prodigious martial talent and can rapidly learn any personal, non-supernatural combat skills you encounter, whether melee or ranged. This is an experience and skill acquisition multiplier, not a flat improvement, and further scales to the strength and skill of your opponents and trainers: the better they are than you, the faster you learn, until you've caught up to them. This applies to both command ability and personal skill.

.

.

Soul Talent

Cost: 10

You feel. You have a prodigious talent for ki arts (aura, chi, Hamon, Phonic Gain, Spiral Power, Haki, etc.) and magic and will rapidly learn any such mystical arts you encounter and are capable of using. Unlike the buffs from Heritage or Shroud elements, this is an experience and skill acquisition multiplier, not a flat improvement. This effect further scales to the strength and skill of your opponents and trainers: the better they are than you, the faster you learn, until you've caught up to them.

.

.

Mapper

Cost: 10

This app offers maps of the current world you're on, with points of interest annotated. No information that could not be discovered by casually asking around is listed, so while a public-facing organization like a merchant's guild will be annotated, the local thieves' guild will not. This map will update itself if you discover a point of interest that would normally be left off of the map. You are also able to search for points of interest. Tapping on a point of interest (or the equivalent for your smart device) will bring up a short description of it. You can add any number of your own annotations to the descriptions. Descriptions will update in real-time if there are significant changes, such as a store closing.

.

.

Catch-A-Ride Crew Training Program

Cost: 5

Requires: at least one registered vehicle

We at the company fully realize that, in some cases, you and your waifus may lack the necessary skills needed to properly operate or maintain your chosen ride, which would make using them impractical at best and impossible at worst. To rectify that, for a small fee you can opt to have your newly purchased waifus undergo a 24-hour training course, during which all the skills needed to properly operate, repair, and maintain all your registered rides will be downloaded into their brains. Delivery of waifus will be delayed until completion of the course

For captured or pre-existing purchased waifus, you can opt to have them undergo an 8-hour training program via a company-approved VR system, during which they will gain the skills needed for proper manning of your rides. Purchase of additional vehicles may require further courses, should the tech bases be significantly different.

Black Pearl

Source: Pirates of the Caribean

Cost: 15 Points

Notable features: 32 canons, Legendary speed at sea being the fastest ship when sailing without mechanical help.

.

.

Universal Calibration

Cost: 10

Entering a new world, only to learn that the capture targets are out of your strike zone, can be… inconvenient. This perk will automatically adjust the ages, sexes, and sexualities of any canon characters, and the population's average beauty level, to better suit your preferences. This will occur before you or anyone in your retinue enters each world for the first time, and even affect the portions of the population that you have no interest in.

The locals of that world will not notice these changes - from their perspective, that's just how things are. Any events of canon that would be affected by the alterations are adjusted as little as possible to keep the same general flow of events, keeping the scenario recognizable even though the participants are possibly decades older or younger. This perk cannot fundamentally shift a setting's danger rating or make capturing individual targets any easier.

.

.

Binding: Company Stamp

Base Cost: 0

This permanent magical tattoo instills only the mental effects common to all bindings. To capture targets, you may apply this tattoo using a thumb-sized ink stamp. You can only have one stamp at a time, and only you and your retinue members can perceive the stamp when it's not in use. The inked part, on one end, contains the tattoo's core, a circular design that serves as your emblem.

Stamping requires 3 seconds of sustained contact with the target's skin, from the stamper's perception, to start the tattoo-creation process. You must apply enough pressure to make the ink transfer properly. The most popular stamping sites are typically the pubic region, lower back, or back of the neck. Newly-applied tattoos require 72 hours to ramp up to their full effect, from the perception of the person stamped.

During the ramp-up period, additional ink will fill itself in around your emblem to form a much more elaborate design, about the size of the subject's palm, that represents her history and personality. Captured subjects and people they know will not notice a tattoo-in-progress until it completes itself, at which point they'll rationalize away its sudden appearance.

Stamped targets only count as captured at the end of this period, when the tattoo completes. Completed tattoos are always perceptible. A stamp's location on a target's body may be repositioned after the fact through the company app.

The stamp never runs out of ink and cannot be used accidentally. If you are stamped, by yourself or another, it will only have cosmetic effects. If one of your subjects marks someone new with it, the newbie will feel its effects as if you had used it on her yourself. The anti-loss, -theft, and -destruction measures on the company's smart device also apply to this stamp.

Item Selected: Akuma no Mi Logia (Mist Fruit)

Costs: 40 points

A Devil Fruit, this fruit turns the user into a Mist Human.

Advantages: Immunity to regular physical attacks; create mist; Control mist; Able to create and control all kinds of mist.

Disadvantages: Weakness to Haki; Lacks most direct physical ability (Note: fruits bought from the system lack the fear of seawater, but one can only consume one fruit)

.

.

Template Stacking II (Syura, Akame Ga Kill)

Costs: 40 points

The Template of Syura, the son of Prime Minister Honest. Syura is a genius martial artist who combined several martial arts from across the land, possessing an uncanny ability to find people to serve him, and most relevantly he has the Teigu Shambhala, which is capable of spatial manipulation, allowing him to teleport people across large distances as long as he has set a marker on that location beforehand.

.

.

That should be enough for now. I understand that the body is the most important in the world of One Piece and Haki as well, so the Body, Martial Arts, and Soul Talents are a good pick. The mapper perk is to help me at least have a general notion of the sea around me instead of going in completely blind all the time and the Training one is to not have those in my ship be unable to be of use while sailing.

The Black Pearl is because it is an awesome ship and faster than any other while they don't use engines. It should be fast enough for me while not having any need for fuel.

The stamp is because it would be fun to make it almost as if I have a guild like Fairy Tail on my side, all sporting similar marks on them. That it is free also helps.

For the Universal Calibration, well, I just wanted to mess around and see how things will change under this option since it changes things automatically without my direct input.

I took the Template for Syura because of his Teigu, if I am going to One Piece I ought to have a quick travel option.

And finally, if I am going to be Tokito, the Mist Hashira, then I ought to have mist powers! Simple as that.

There are other things that could be of use and it seems like there are some that should help with members of the crew, but the Body Talent is spread to everyone anyway and I don't want to invest much when I don't even know if I can get a crew in that sea or if I will go the Mihalk route of being a solo badass.

Anyway, with my options selected I still have a whole lot of points.

.

.

Please choose your waifus to accompany you. Please note that the first buy is only up to three individuals and in the future, you can only buy a waifu once per week.

.

.

Well, this is interesting. This is like a full catalog of waifus to choose from, there are girls from all sorts of words in here.

Smiling lewdly I begin checking the girls present and thinking about who to add.

It takes me a while but I make my decision in the end.

.

.

Terumi Mei T6 (Naturo) - costs: 50 points

Dorothea T6 (Akame Ga Kill) - costs: 50 points

Yotsuba Maya T7 (Mahouka Kouko no Rettosei) - costs: 100 points

.

.

This is a more or less good foundation. Dorothea may not seem that interesting, but she is an amazing alchemist and scientist that was able to enhance her own strength considerably in a world in which physical strength is quite limited compared to One Piece. If she comes to One Piece she might be able to do some truly amazing things. That she also has her Teigu that basically is the same as the Vampire Fruit except for darkness powers, so a plus there.

For Yotsuba Maya the reason is even simpler, her specialized magic is absurdly BS and she should be capable in several other types as well and, most importantly, she is intelligent. In a world with the WG around, I need someone smart to help me, and she fits the bill nicely.

As for Terumi Mei, I was thinking of getting her to be my First Mate. She is capable enough and relatively very strong while ruthless if needed, with her around things will be that much easier to deal with.

It is a good and strong group, even if I do think I am lacking in people capable of cooking and other such matters of the ship, I can only hope that the others can improve on that with the help of the catch-a-ride training and that I get to be able to recruit locals

I still have points, but I will leave those for now.

Regardless, I am mostly satisfied with this. Now I just press play and start playing the gaaa-

3° Person P.O.V.

A young teenager lay on his back on the deck of a black ship that was docked in a distant corner of Fishman Island.

The young teen is a short, muscular young man of light complexion with long, straight hair of a black color that fades to mint green as it approaches his waist. He wears his hair loose with two clumps protruding slightly from each side of his head, a set of marginally shorter hair left down to frame his face, and unruly bangs over his forehead. He also possesses large, empty-looking mint-green eyes. He was wearing a slightly turquoise tinted uniform of sorts consisting of a buttoned shirt reminiscent of a kimono having long sleeves and with a white framed collar. On the back, there was a large and boldly written 'Destroy' in white, a shirt pocket on top of the left breast and a white undershirt.

On his side was a seemingly normal Japanese Katana who seemed to be ordinary and not so at the same time.

"Look, Galette, the ship actually has someone in it." A man with thin legs, long arms, a thin mustache, and a hat that looked like a chimney said to his companion.

The woman just huffed in irritation as she looked at the man.

"And what of it? Are we to get out of the island just by relying on this ship?"

"At least with that we wouldn't be noticed and our mission can stay a secret longer." Diesel countered as the red-haired woman snorted before moving along towards the teen, her hips shaking seductively as she walked.

She may not want to sleep with him, but she was no prude and there was no other man around, especially none that would have the guts to try and hook up with her. Being one of Big Mom's daughters had this sort of effect, no one touched her normally at all.

When she was about to step on the boy's head to end him he moved out of the way, his speed far too fast as, even while sleeping, he avoided her attack and took out his sword, slashing at her body at speeds that she only barely managed to use what armament haki she could to lessen the blow, turning it from absolutely deadly to only grievous injury.

She could only gasp in pain, her partner moving in fast, trying to punch the teen that just attacked his boss's daughter, only to have the kid avoid it perfectly and slash at him just like with Galette and, while Diesel managed to use more haki compared with Galette, it was not enough to avoid the blow.

.

Defeated bounty: Charlotte Galette, Diesel. Total bounty - 72 million. Points earned: 7 (left 2 million bounty)

.

Blinking once, twice, the teen's eyes widened as he saw the blood oozing out of the two people on the floor.

"Shit, what the hell is going on?" The teen said as he started to move, trying to stop the bleeding of those two the best he could as he had no idea what was going on.

He ran across the ship and, thankfully, it came fully stocked with everything including medical supplies so he tried what he could to help those two.

He took a good while to do it and, by the end of it, he wasted a lot more materials than strictly needed, but stopped their bleeding out. With that he started to access the situation, his eyes widening as he recognized his own looks, the ship, and most worrying of them all, the ship he was in.

That whole shit before wasn't just an elaborate dream or a game of some sort, it was all entirely too real and he was now in One Piece.

And looking at the two he just saved, he quickly enough recognised the two as members of Big Mom pirates, truly a troublesome existence that he did NOT want to provoke. Even if the ship might have already sailed seeing as he almost cut one of her subordinates and one of her daughters in half.

"Fuck! Fuck, fuck, fuck, fuck, FUCK! What the hell do I do? I don't even know how to fight!" The teen complained before thinking of something.

Feeling a bit bad for doing that, his survival was paramount so he checked his pockets until he found what he was looking for. The Stamp that, according to what he knew, could 'capture' the one stamped by it.

He was not sure it worked, but it might work and that was enough for him now.

Going first to the girl he pressed it against her exposed left shoulder. After a good few seconds, he removed it and that was done.

.

Waifu capture start, time for completion 72 hours (need the target to be awake for the time to start counting). Cost (12), remaining points (100)

.

"Good, it works. Now, for the next one." The teen said as he moved toward the explosion man.

Pressing the stamp in him he waited for a few seconds before taking it out and... failing.

"Oh, come on." The teen said as he pressed again, trying one more time but failing all over again.

This was not good. He wanted to bind them so he could use them to make Big Mom not hear about him which would make things way easier. For the girl that had worked, she could report what he wanted later, but this guy wouldn't be like that.

Feeling irritated and not wanting to die, the teen decided to do what he had to do. Taking the larger man in his arms, he moved to the back of the ship and, looking at the low water, he threw the older man in the seawater.

Upon hitting the water the man awoke and started to move around in the water, but it was too late as he soon after died drowning in the sea.

Feeling a bit uncomfortable the teenager didn't try to think much about it as he moved toward the girl instead, holding her in his arms he moved around inside the ship. Deep down there was a dungeon of sorts that seemed flimsy but when the teen tried to test it he saw that it was very tough despite its looks.

Putting her there he closed the door and left the place. It would take a time before she was fully captured and thus cooperative, but this way he at least could make sure nothing much happens in the meanwhile.

Getting back to the deck, the teen looked around and saw the surroundings without the extreme worry, thoughts on what to do moving forward flashing through his mind.

"How the hell can I survive if Big Mom decides to send someone against me?"

Big MOm, one of the Four Emperors, could be said to be the weakest of them all. However, it was also true that this title of 'weakest' was only relative to the other emperors and, even then, it was debatable between her and Shanks. Not only that, she had a huge crew filled with capable fighters and a lot of influence all over the world, escaping her would not be easy.

Cursing his luck for who knows how many times, he starts to think of ways to deal with it. He needs some way to at least have a chance to deal with it, after all.

After a good while, he finally decides on what his next plan of action should be, besides waiting for the forty-eight hours for his bought waifus to show up. Namely, he searches his pockets and finds what he was looking for.

Shambala, the Teigu of Syura. With this in hand escaping, at the absolute least, would be relatively easier. This Teigu has two aspects, first is that it can teleport once across large distances but needs some time to recharge after each use and needs for the destination to have had a marker set. The second is fast teleportation within a determined area, it would let him become similar to Minato in certain ways even if only under a limited space.

He would need time to train on how to use it, but the knowledge and strengths of Syura flowed through him, and as time passed the teen felt more and more sure about how to use this teigu.

After some fast practice with the Teigu to make sure he understood how to use it, he put it down and took out his sword. He could have taken the Devil fruit that was on his other pocket, but if Big Mom might be sending people over then they would know Haki, and having a logia but no Haki against an experienced Haki user was a terrible idea. Better to focus on properly learning how to fully master the skills that this body knew and acclimate himself to them.

With this sword in hand, the teen decided to try out his original ability, namely the fact that he was in the body of a Hashira of all things, and one that had access to his Demon Slayer Mark as well as immense talent.

Taking a deep breath and hoping the talent was still there, the teenager jumped in the island properly before starting his practice with the sword.

As he adjusted to his new body and skills time passed. It was a pretty slow and tedious process, but the teenager was glad as he could move his body at speeds he honestly thought would otherwise be impossible and his ability was many times greater than he thought he should be. That was not only Tokito's body though, the powers earned from Syura, while seemingly useless, included a lot of knowledge about footwork that he was slowly uniting with the Mist Breathing, causing his speed to constantly improve.

As his skills were slowly, but surely, increasing the teenager lost the sense of time, only stopping as yells from inside the ship came out.

Jumping back to the ship and moving to the source of the sound, the teen was not surprised to see that his prisoner was awake.

"What the hell is going on? Get me out of here!"

"How about no?" The teen said as he took a chair around and sat down. "You came to my ship, I didn't go hunting you down."

"Says the boy who almost killed me!" the redhead yelled.

"... Do you want a repeat of that?" The teen said, trying to show ruthlessness.

It worked as the blond calmed down and looked frightened, looking from one side to another.

"Where is my partner?"

"Dead." The teen said without hesitation. It was the truth after all.

The Redhead gulped.

"W-What do you want from me? Who are you?"

"I want you to stay here for a bit before contacting your boss, explaining that your partner died due to an unfortunate accident, you both were walking on a cliff and he fell on the ocean or something. I don't really care even if you say you fucked him so heard his heart give out, do what you want as long as the message I want is sent. And as for who I am... call me Tokito."

AN:

Hope you guys enjoyed this. I am not sure if or when this fic will continue, but it is interesting to write based on the rules of the Waifu Catalog.

The MC is in a few years in the past and we have Universal Calibration, meaning some potential waifus are older, others younger, all to fit in for the necessary looks. Beyond that, what will happen is mostly in the air. The MC has in total 227 points to spend and a crew to fill, check out the catalog if you want to offer suggestions, please note that at most I can accept up to Tier 6 and he can capture waifus from One Piece by 60% of the price they would have if he were to buy them.

He can get points in a few ways:

- Defeating and/or killing pirates. For every 10 million bounty he gets one point;

- Crew bounty. For every 10 million total bounty he gets 1 point every month;

- Selling Devil Fruits to the system. Gets between 5 and 20 points for fruit;

- Selling waifus. Capture waifus and sell them for 80% of their value if he were to buy them;

As it is seen, there are various ways to do things and there are a whole lot of things possible. I will give three days from launching this chapter and will use one of the reviewed suggestions for the next bought Waifu.

Anyway, thanks for reading and until next time.

Peace.
