A month passed in almost a blur.

The mornings began with intense training for his body. He ran until his legs shook and his lungs cried. Then he moved on to lifting boulders as weights until his arms cried just the same. Then he did the same with his legs, balancing and lifting the boulders with his feet.

…Until they also cried.

Then he had breakfast.

Then he made his way through the base asking anyone who would to spar with him.

He got his ass kicked.

A lot.

Especially if any of the higher ranked marines wanted to scrap when there was no pirates around.

Once he pulled his bruised self out of the heap he was left in, he dragged his sorry behind into the forest to punch trees into mercy until his knuckles cried.

And then blindfolded himself with his thingamajig marine scarf by tying it around his eyes and set his Haki Pendulum into motion and stepped between the thick swinging logs.

And got smacked around constantly by them until his entire body, mainly his torso and head, cried for mercy.
And that summed up his day prior to lunch.

After which, he would repeat it.

All over again.

Alongside training Soru of the Rokushiki. After which, he would drag his tired, beaten and bloody body back to bed to rest and repeat the very next day once again.

Really, it was just a month of his entire body screaming, begging, pleading and crying like a little girl for mercy.

It was probably only because of how superior his new body was, that he hadn't just keeled over and died out of pure exhaustion.

Or pain.

At the very least, he had some results to show for it.

"Hey, you blocked it!" Commodore Yarisugu grinned at him as he pushed down with one hand, large sword in grip.
Kaden, blade in and and both hands grasping his cutlass grit his teeth, arms shaking as he held the huge mans strike back with all his strength.

It wasn't meant to be condescending he was sure, because generally, Yarisugu was only a prick and cruel to pirates.
But…it still felt like it.

With a growl, Kaden pulled his hands down, grinding his cutlass' blade down the mans much larger one and went down with it.

The sheer force behind the mans continued swing as he did, allowed Kaden to propel himself forward with it and kick out, launching a stomp at the much larger mans kneecap.

Which did absolutely nothing.

The man didn't even grunt, his leg only vibrating lightly from the impact at the same time his huge sword slammed into the ground just behind Kaden.

Yarisugu's grin widened, one of his huge meaty hands darting down with a speed that belied his size and gripped Kaden atop the head and bodily picked him up.

And slammed him bodily into the ground hard enough to knock the wind out of him and drop his sword.

The ground indented under his back from the force of it even as spittle shot up from his mouth.

Hacking a silent cough, Kaden rolled back just as the huge Commodore tried to stomp down on him.

As he rose back up onto his feet he pushing off, kicking against it rapidly and shooting forward far faster than he usually did.

Only for an arm to slam into his throat and clothesline him. He flipped around the arm and slammed face first into the ground, stunned.

And he did not move.

"U…uh….uuuu…" A feeble, almost whimpering groan escaped him as he tried to regain his breathing.

"Good try, but not quite kid." the queerly dressed Commodore laughed and walked off.

As was custom around here.

Honestly, the place was full of cunts. And he didn't even recognise any of them besides the Commodore, none of the kinder ones that popped up when Smoker and Tashigi transferred to G5.

Most likely because they only ended up there after the War Of The Best.

Rolling himself over, Kaden flopped onto his back and stared up at the as always, dark and rumbling cloudy sky above.

…He'd lasted a whole two minutes against the Commodore this time. Three weeks ago, he hadn't even lasted thirty seconds.

"Pr-pro…progress…yay." he coughed out, laughing tiredly.

At himself.

It took him a good few minutes to get his breath back under control and then find it in him to pull himself up to his feet, propping his body up with his sword all the way like a walking stick.

He stood there on shaky legs, balancing his body on the blade, before taking a deep shuddering breath and pushing himself up fully with a groan and sheathing it at his waist.

"….Yeah, not fun." he winced.

He'd found though…that, the more people he trained against and the stronger, the more his skill seemed to increase.
…Or at the very least, managed to last long enough for it to be considered a spar.

'I fucking hate this place.' he groaned inwardly as he began hobbling away from the training area where multiple marines around him were going at it.

In the past month, he'd pushed himself to the absolute limit and then more. Trained in ways that vastly overshot the scope of training the previous Kaden had went through.

Yet…the gains he'd gotten according to his status screen, were minimal.

Devils Fruit: -

His physical stats had only increased by a few points each. Which, was a pitiful amount for just how much and hard he'd trained

…If they were linear at least.

He'd noticed when he started sparring as well with the stronger marines, that the numerical value of his skills had shotten up rapidly initially, before slowing down a lot.

His hand to hand combat for instance, had reached eighty, a week and a half ago. The progress had slowed down a lot.

But he was training just as hard, if not harder and even getting more time sparring in because he was lasting longer. And even managing to train longer the more used to training he got.

'Well at the very least, I know I'm making some progress with haki.' he mused, eyeing the screen as he hobbled on his way.

It was dreadfully slow rising, but each single point increase he saw, drove him on. It didn't help him in anyway beyond telling him, he was on the right path and just had to keep going.

Though considering the progress he'd made so far….

It would take over a year before he reached the one thousand mark.

And so far, all he'd been able to do between the two was dodge a few times between the swinging tree logs.

Beyond that he didn't know why his armament had risen though.

Kaden sighed and then continued on.

Though instead of heading back inside the base, the blonde, bloody and beaten petty officer continued his hobble…towards the back port.

Where they kept the mass of battleships G5 went through because they were absolutely shit at taking care of their equipment. Basically, it was a ship graveyard.

While everyone was busy, he figured he'd go for a little….swim. And maybe take a little peak down below the water and have a looksie at what was going on.

Specifically, at what was underneath the battle ships stationed at said port.

…And maybe scrape off a little shiny green sea stone while he was there.

Just over an hour later, Kaden burst up out of the roiling sea of the New World, naked as the day the teen marine was born.

He floated in the water for a moment between two massive and heavily damaged battle ships, a large soaked sack held over his shoulder, before swimming back to shore.

Usually, ships like this would be brought onto land and left there until they were slotted to be taken apart and their pieces used for the creation of something new.

G5 were just too lazy though and had simply anchored them in the water, leading them to getting even more messed up by the crazy weather patterns of the New World ocean.

'Their laziness is my gain I guess.' Kaden snorted tiredly. He didn't even have the energy to laugh over it, or the fact he just filled a sack up to the brim with expensive sea stone that would probably go for a pretty hefty amount on the black market.

Once he made it back to the shore, he collapsed on his backside just right next to where he'd dropped his marine uniform, dropping the large sack he was carrying, taller even than he was and stared up at the cloudy, rumbling sky.

"…I fucking hate this place." Kaden groused with a sigh, running a hand through his damp blonde hair.

The novelty of being in the One Piece world and having a body so strong that he could snap a world class body builder from his own world easily with, had quickly worn off.

Within the first week of being there.

If he was in say the East Blue, he'd probably be enjoying himself a whole lot more.

As it was though, he was stationed in the New World, and near every few days he was called to action to take on pirate crews. Just the other day, he was almost squashed to death by a literal half giant pirate captain with a bounty of sixty million and would have been dead right then and there, if not for Commodore Yarisugu zipping in and cutting the half giants arm clean off.

….Said half giants corpse was still strung up outside the front of the G5 marine base like some kind of macabre trophy or flag.
Once more Kaden repeated: "I fucking hate this place." he sighed again. The pay was shit, the living conditions were crap, the weather was trash, he was surrounded by absolute freaks like Commodore Yarisugu and Vergo on the daily, and to top it all off-

The place was a complete and utter sausage fest. The closest he'd gotten to any girls in the month he'd been here, had been a few quite attractive pirate girls.

Who were pretty brutally chopped up by the freaking G5 marine mutts.

And he wasn't anywhere close to leaving this place either. He needed at least Soru and Geppou down before that, preferably more. Yet, he hadn't even gotten Soru down yet.

'Coby went from that tubby little runt not even as strong as an average grown man, to being able to use both Soru and Tekkai within forty days.' Kaden clicked his tongue in annoyance.

At the very least he knew he had a way better starting point than Coby did starting off. And physical ability mattered the most when it came to the Rokushiki, less the skill.

And to use the Rokushiki, one had to cross at least the threshold of super human ability in this world, which was counted at five hundred doriki.

An average fully trained marine soldier had a doriki of ten. Going by that, the average grown man probably had a doriki of around five at most. And Coby would have been way lower, probably at like two or three at most.

Which meant in forty days, Coby had basically speed run his way to five hundred doriki from basically nothing, and was probably higher actually considering he had two of the six powers down pat at that point, which he could only train in properly once he'd hit that five hundred threshold.

Which probably meant…Coby got two of the six powers down in maybe like a week or two at most.

Was that just because he was being trained by Garp, or-

'Am I just that freaking inferior to Coby talent wise?' Kaden grimaced at the thought.

Thinking on Coby though….

Kaden's eyes glanced to the battleships floating in the port bay and eyed them speculatively. 'Garp trains every day by punching battleships. He even trained Aokiji that way and Coby copied him.' he mused.

Of course that wasn't even an option for him, because he was not capable of pulling those damn ships onto land himself, he lacked the strength. And he wasn't too keen on the idea of asking anyone else at the G5 base for help.

Quite frankly, he couldn't stand the people here.

They were absolute sick freaks, they honestly weren't that much better than pirates really. Which honestly made sense considering their leader was a fucking undercover pirate himself for one of the most ruthless and degenerate pirates there was.

Kaden found his teeth grinding as he thought of that sick fuck Doflamingo, which inevitably led to him thinking about Wano and Kaido, and all those poor people like cute little Tama starving right now.

And it grated all the more that he was absolutely powerless to do absolutely anything at all about shit like that.

Even if he was fucking strong enough to do something about it, he literally would not be allowed to. Doflamingo was protected by his status as a Shichibukai and the fact he was a former Celestial Dragon with tons of dirt on them, and the marines refused to face off against any of the Yonkou, because they were too chicken shit.

The second he tried to do anything about monsters like them, he'd be cast out of the marines and branded a pirate himself.
So much for being a fucking marine that stood for justice and protected the innocent, huh?

Kaden shook his head, putting it out of mind for the moment, it wouldn't do to dwell on stuff like that right now. He could worry about it when he wasn't a no name weakling piece of trash.

This was a world where might made right, and he currently lacked might.

'I suppose I could steer one of the ships onto land myself once I got Soru down.' He mused, taking his thoughts back to where they started.

He wondered idly, if Vergo could measure doriki?

He'd really rather not deal with him unless absolutely necessary, but as it was, getting a measure of his doriki, was one of the few ways he could see where he stood in the world currently.

He found Vergo where he usually was when he wasn't out 'hunting pirates', which was probably more of an excuse for him to meet with Doflamingo and others of his crew.

Sitting in his office, an empty plate of food in front of him and a piece of a steak stuck to his cheek.

Vergo stared at him blankly, not at all asking why he was there. Honestly, the guy was a weirdo.

"Can you measure doriki?" Kaden asked bluntly, getting right to the point.

"Mmm, yes." Vergo nodded.

And said nothing more.

Kind of annoying really, but Kaden wasn't too annoyed, in fact he was rather pleasantly surprised.

It was far easier to find someone who could measure his doriki than he thought it would be.

"Can you measure mine?" Kaden asked, "Right now?" he added, just to make sure he wasn't left hanging with a simple yes and the man just sitting there blankly.

"I suppose," Vergo nodded, "Make it quick though, I'm busy playing golf with my brother right now, you see."

Vergo in fact, did not have a brother. And since he was sitting behind his freaking desk, he clearly wasn't playing golf either.

"I'll be quick." Kaden replied, instead of calling him a retard like he wanted to.

"Okay," Vergo nodded and stood up, walking around his desk to stand in front of the blonde teen and held one hand up, palm facing Kaden, "Punch my palm." he instructed simply.

Quick as a flash, Kaden did as bid and struck out with a rapid blurring punch with all his strength.

It slapped meatily into Vergo's palm, which barely budged. And then his palm glowed with a soft green light.

"570." Vergo said a moment later after the soft green light faded away.

Kaden's eyes widened.

…That was actually way higher than he expected.

But beyond that, something else occurred to him. It was specifically ten times the number of his strength stat.

'Which means, my doriki is specifically ten times that of my strength stat on this stupid screen thing.' Kaden realised happily.

Before that sudden joy was doused with realisation.

The max number his strength stat could go to on the screen, was five hundred. Did that mean…his strength was capped at five thousand doriki?

Only a thousand higher than pre time skip Lucci?

"Well….that sucks." Kaden spoke aloud, shoulders slumping in defeat.

"Yes quite middling," Vergo agreed, "You should really train more."

…Fuck this guy.

Kaden left Vergo's office behind in a bit of a daze, making his way back to quarters.

As soon as he was back inside his bedroom, he collapsed on top of his bed and stared up at the ceiling, numb.

What was he even supposed to do at this point? Five thousand doriki, was pretty good for paradise, but…

When it came to those that really mattered? It was absolutely trash. With a maximum physical ability of that…he would be hard pressed to match up to the likes of secondary officers in a Yonkou's crew the like the Tobiroppo, never mind the actual commanders…and a sure far cry away from the likes of the Yonkou themselves.

His full potential was literally…fodder tier in the end.

'This is what it must feel like to be Yamcha.' Kaden thought dimly. He always used to have a good laugh about the Yamcha jokes people made.

It wasn't so funny now.

With such low potential, it didn't really matter what he did. Even if he got a supremely overpowered devil fruit like Whitebeard's, that wouldn't change anything because it didn't make him invincible.

He'd just get bodied instantly by someone like Kaido the second they landed a physical attack on him. Not even just Kaido, but even the likes of post time skip Luffy could probably drop him with a few punches that landed with Armament and shit.

A powerful devil fruit only made fodder more annoying fodder, it didn't change them from the fodder they were at heart. Even something like Enel or Kizaru's fruits would only go so far.

"Fuck this blows!" Kaden snarled, bouncing up from his bed and swinging around to throw a kick at the base of his bed.
It shot up like a football and smashed into the wall hard enough to leave cracks in it.

"Huh…?" Kaden blinked as something caught his eye. Something that looked like a small latch on the floor?

That wasn't right though. He'd seen under the bed before he was sure, and he'd never seen anything like that before.

Just before the bed clattered down atop the floor once more, Kaden reached out and caught it with one hand and hoisted it above his shoulder.

Annoyance at his situation put out of mind for the moment in favour of his confusion, Kaden crouched down, balancing the bed above his head and dug his fingers into the wooden flooring, ignoring the small key latch he could see and bodily ripped it off, like tearing a piece of paper in two.

…To reveal a small treasure chest not much larger than his head.

"What the fuck?" Kaden blinked, staring at it. Seriously, he could remember from the memories of the fuckhead who had this body before, him cleaning under this bed multiple times and he had no recollection of this little secret compartment in the floor.

Reaching in, he grabbed the small treasure chest and dropped the bed back down atop the floor, before plopping his ass on it and popping over the treasure chest to sate his curiosity.

…All he found was a small black book, more like a diary actually.

Eyebrows rising, Kaden lifted the book out and tossed the chest aside, then his eyes widened as he saw his name on the front of the book.

Or rather, two thirds of his name.

Kaden D. Topman.

That was the name printed on the front of the book.

That wasn't his name.

But…Topman. That was familiar for some reason.

His birthname perhaps? Freeman was the name of his adoptive parents in this world that had been killed by pirates and sent the original owner of this body straight into the arms of the marines.

The absolute cunt.

If it wasn't for him signing on to the marines and getting him stuck out here in the New World and part of G5, he wouldn't even need to worry about his strength all that much.

But no, he was a New World marine, if he left, he'd be getting top tier people sent after his ass to hunt him down. Hell the fucking standard for someone of his station deserting the marines, despite being a petty officer, would get him slapped with a twenty five million beri bounty.

How was that even fair? Just leaving his post would have him get a bounty higher than fucking Arlong.

Fucking bullshit.

Kaden sighed, and opened the book up, then blinked as the first words at the very top filtered through his mind.

'To my precious son Saint Kaden, if you are reading this now, it means our attempts at placating my father have failed, and I am dead.'

Oh…well wasn't that a lovely opening sentence.

Though considering he had been adopted, and neither of his adopted parents had the initial D in their name, he'd already come to the conclusion that his birth parents either abandoned him, or were dead.

Wait.

'SAINT KADEN?!' his eyes flew wide opened as the title registered in his band and he gaped, mouth hanging low in absolute shock.

As in…a fucking Celestial Dragon!?

'I am sorry my precious son, but in the eyes of my father and his compatriots, you are an abomination. The blood of the Celestial Dragons runs in your veins, but so too does the blood and will of D, the mortal enemies of we gods. You are one who was never supposed to be born.'

Oh…peachy. Absolutely lovely.

This day could not get any better. First he finds out his pitiful potential and limits, and now he found out that he was…an abomination who should never have been born.

Well his counterpart was…before he somehow forced him into this position. God he fucking hated the other Kaden more and more with each day that passed. Seriously, fuck that guy!

He should be surprised he really was from the D Clan and apparently a Celestial Dragon who was not afforded the same privilege and riches of the other.

But he wasn't.

Because so far, that was just how his luck seemed to roll in this world.

'My name is Saint Evelyn Topman, former elite knight of the Holy Knights and daughter of Topman Mercury the Warrior God of Justice, of the five elder stars, I am your mother and a former Celestial Dragon. I was banished, for falling in love with a slave, who bore the initial D and refused to bow to anyone despite where he was in life. The sheer strength and will of Carrion D. Stone captured my heart. I could not help at the time, but wonder what kind of amazing child a man such as Carrion and his blood carrying the Will of D and myself carrying the potent powerful blood of the gods who ruled this world, could create. And I could not resist him and that lure. And thus, you were conceived.'

Kaden stared blankly at the paragraph of his apparent birth mother introducing herself to him and…the story behind his birth. Basically, his mother got hot heavy because his father wasn't a little bitch and bowed to her and the other psycho bubble heads up top torturing him, fell in lust with him and the idea of some super baby between her and him and bounced on his pogo stick.

Still a better love story than Twilight he supposed.

So much for that fucking amazing potential though, he turned out to be an absolute and utter scrub.

What an absolute waste of a thing to die over mother.

'My father and the others, too rigid in their belief and sticking to the old ways are too foolish to see what you represent though. You my precious Saint Kaden, are the ultimate life form of this world. Or perhaps they do realise, and so they fear your potential? The fools, with you fully grown we would never have to worry about trash like those impotent emperors snarling at the feet of their betters, with you at the helm we could usher in a new age of dominance! No matter, should I fail to convince father and the others, I will simply do my best to strike them down, mine is the power of the heavens after all, the lightning lightning devil fruit will not fall so easily they shall find!'

'So my mother was apparently absolutely fucking crazy.' Kaden thought blankly. And apparently she had Enel's fruit before he did.

And all that for him, who turned out literally just be fodder. It was kind of funny, in a sad pathetic kind of way that she threw away literally everything for someone so innately weak.

Kaden couldn't help but chuckle.

'I am not so foolish to think That the combined might of your father and I have no risk of losing. That is why, I write this book to allow you to know of your origins, and your birth right as the true god king of this world, the one who above all else everyone should bow to! And of course, is the fruit I have included in this chest alongside this book. The ultimate Paramecia Devil Fruit, the Spirit Spirit fruit which among many other things, will allow you to look upon your very soul and see your greatness at the very core of your being, store any item you please within your soul, show you the best ways to reach that potential, and should the worst come to pass, leave this very world behind and take the power you have gained and the potential of your birth, to a whole new world you can conquer and grow to your peak without fools like my father trying to oppose your ascent!'

Suddenly, his birth mothers garbage written down here, wasn't so funny anymore.

Kaden stared blankly at the words, processing that last part specifically, before his eyes lit up with fury, "That….absolute fucking bastard!" he snarled, the fingers of his free hand digging into his palm hard enough to draw blood even through the bandages that covered them.

That explained fucking everything,

How he ended up here, where this stupid ass weak crappy game system looking thing came from. And why his limit was so damn low.

The other Kaden had literally switched bodies with him using this fucking Spirit Spirit fruit fuckery, and took all his potential with him, leaving him with nothing but the dregs.

It also explained the gaps he felt in his memory. somehow, that spirit fruit bastard was able to effect even the body he left behind and scrub the knowledge he would have gotten of that pricks actions and inheritance from his mind.

He didn't even remember where the other Kaden had gotten this damn chest. He couldn't even trust his own memories growing up in this world to be exact, who knows what he'd changed there.

"I fucking hate that guy!" Kaden hissed, trembling with fury.

Never before in his life, not in this one, or the last had he ever felt such anger Before. He'd stolen his body, he'd stolen his life, he'd forced him into a situation where he'd be branded a criminal and hunted down by super powered freaks if he tried to leave, in an ocean filled with monstrous freaks, governed by monstrous freaks.

"I'll kill him! I'll fucking kill him! if that bitch was still alive I'd kill her too!" Kaden dropped the book as he red tinted his vision. Those fucking bastards, how dare they! That fucking whore how dare she!?

Fucking useless grandfather, couldn't even kill a piece of shit in the womb despite being one of the literal rulers of the world, how fucking useless could you get!?

Now that guy with all the power of a One Piece freak was probably running riot back in his own world while he was stuck fucking here, as the scrubbiest scrub that ever fucking scrubbed!?

Blood dripped from his fingers, pooling on the floor.

And lightning crackled into existence, black bolts zipping over his body, before a wave of red erupted from his body, blasting outwards.

"…Bastard, you think I'm gonna just lay down and take this!?" Kaden snarled, waves of red roiling from his body like raging waves, bolts of black crackling over his body.

Like hell he fucking would!

With a snarl, he grabbed up the book, the roling wave of energy and black bolts fading away from around. There was still yet more to be found in it and he tore through it, taking in everything his mother, no that fuckers mother bestowed to him, everything she knew of the Spirit Spirit fruit, amongst paragraphs upon paragraphs of his greatness and right to rule this world and do whatever the hell he wanted.

'-Do not be disheartened if the potential listed by the Spirit Spirit fruit is low to your gaze, keep in mind that your potential will grow with you until you reach your full maturity, at which point you will no doubt be unstoppable and-'

There!

Ignoring how his mother went on to another tangent of that trash bags potential greatness, a nugget of useful information stood out.

This crappy screen of his, only showed off his current potential, not his potential when he was fully grown.

'When is full maturity though? Eighteen? Twenty one? Either way still not that massive a jump.' his thoughts raced.

How was it even calculated? By years? Then if he divided his current potential of five hundred by the years he'd lived, he'd get roughly thirty five. At eighteen that would take his max potential to six hundred and forty, if it was at twenty one, that would take it to seven hundred and forty five.

Which would make his max doriki either 6400 or 7450.

A decent bit better than where he was currently, but nowhere near the kind of strength anybody of note after the time skip showed off, and even a lot before it.

He would still be fodder, never mind the fact it would take years for his potential to grow to that point and then longer for his strength to reach it.

'Think…how do I do something about this?' Kaden ran a hand through his hair in agitation.

Before his eyes promptly widened as he remembered what the Devil Fruit he was thinking about when he first ended up here in this body.

The clone of Kaido's fruit.

A mythological zoan devil fruit.

Zoan devil fruits were specifically well known for the instant physical increases they gave to their users, and overall enhancer to their limits physically because they were basically being altered to a different species at a genetic level even at their base.

All Devil Fruits did that really, but the Zoan's specifically did it geared towards enhancing the physical prowess of the users.

With the highest tier of Zoan devil fruits, it may be possible to raise his potential far higher than it was currently, and on top of that, it was possible his new potential would be factored in and grow according to it!

"Which means….I need to get these fucking Rokushiki down now!" Kaden stood up, eyes blazing and tossing the black book aside.

And here we are back with chapter three.

Some progress was made by Kaden over little period of time and he learned more of how his 'gamer system' scales to the world around him through comparing it to doriki. Really just a gag thing Oda used once, but it's useful here. And of course Kaden learned how he ended up there. Pretty fucked up really, yeah? It was all a top tier devil fruit used by a supreme cunt in the end, and even beyond stealing his body and sticking him there, he even left him a cripple potential wise.
