The world swirled in a blur of colors and sensations as Tetsu found himself abruptly thrust into his new existence, he was now in a new body, and the world seemed a lot smaller.

Tetsu found himself surrounded by opulence and extravagance unlike anything he had ever known.

Tetsu blinked rapidly trying to figure out what the hell just happened.

First he was one place, now he was suddenly and instantly...here?

A migraine filled his head, information of his current life blended in with his original memories.

Holding his head, his eyes squinted at the sudden onslaught of light, he struggled to make sense of his surroundings, his heart racing with confusion and apprehension.

"Welcome home, young master, I am glad your recovery went well," a stern voice intoned, breaking through the haze of disorientation. Tetsu turned to see a group of servants clad in immaculate attire, their faces impassive masks of deference as they bowed before him.

"Home?" Tetsu echoed, the word feeling foreign on his tongue. He cast a bewildered glance around the lavish surroundings, taking in the gilded furnishings, ornate tapestries, and towering statues that adorned the grand halls of the estate.

Tetsu's new blended memories started to come back to him and he regained some of his senses though he still had a splitting headache.

"Yes, young master," the head servant replied, his voice tinged with a hint of reverence. "You have returned to your rightful place among the Celestial Dragons, where you belong, and we welcome you after a terrible accident in which you hit your head."

The weight of those words settled heavily upon Tetsu's shoulders, filling him with a sense of unease.

'What the hell is going on….?' Tetsu thought, as he was being walked in and escorted to his room.

Tetsu looked around gazing and taking in the sheer extravagance and wealth around him.

When he got to his room he couldn't help but shout aloud.

"A Celestial Dragon?! There is no way I'm fucking in One Piece!"

He was a big fan of one piece throughout his life, anything he did could always be referenced to the limitless expansion of the one piece universe, but it was more a personal hobby, hardly anyone he knew had known he watched it, he wanted to chalk it up to being a prank his friends set on him, and yet, here he stood, surrounded by wealth, in a "room" of his own that looked like an entire home, and in the body of a 4 year old.

"What the hell is going on..."

As Tetsu grappled with the implications of his instant new life, a sudden knock on his door interrupted his thoughts.

KNOCK* *KNOCK*

Tetsu got up and quietly opened the door.

"Uh….yes…um sir?"

The servant seemed to be around the age of 36 but had the furious look of a butler, serious and strict.

"No need to call me sir young master, I ask you to give me a lesser title."

Tetsu sweat dropped at the seriousness of the butler, but he also found this as a test to see if he was actually a celestial dragon and no one was pulling his leg.

"Umm okay Mr. Butler…….I'll call you…Alfred."

The man's eyes shone with some gratefulness at the name and he spoke again.

"Your father has graciously asked me to bring you to the library, he has told me that you have hit your head and it was close to fatal, so he has tasked me with leading you to the library, if you do not wish to follow me, please do whatever you want to do."

I nodded and began following Alfred to the library, where my new "father" resided.

As me and Alfred walked along the Halls a group of Celestial Dragons, adorned in elaborate finery and bearing themselves with an air of arrogance, approached with purposeful strides.

"Ah, the esteemed young master has returned," one of them declared, his voice dripping with condescension. The same ugly celestial dragon looked at Alfred with disgust. "How dare you interrupt my presence with your wretched form."

The flock of celestial dragons laughed and also gave looks of disdain.

Tetsu's stomach churned with discomfort at the thought of aligning himself with these haughty aristocrats, whose disdainful gazes seemed to try and minimize him.

Anger boiled up inside of him, in his past life he was always neutral instead of hateful to the celestial dragons because they were fictional, but now he was in a rage to hear the words of the celestial dragon before him.

"You better watch your mouth you slave whored bastard, any servant of mine is worth more than your worthless life you ugly rat infested bug faced fucker!"

The anger that came out of Tetsu not only shocked him, but Alfred as well, though the celestial dragon was turning blue from rage while all the other celestial dragons laughed.

"That was a good one! He really is slave whored!"

One laughed.

"You do look like a bug faced bastard!"

Another yelled.

"And he did have some slaves killed because they failed to kill a rat he fattened up due to the messes he leaves….."

Another reasoned.

The now embarrassed Celestial Dragon sputtered unable to say anything or respond.

Even though he was four years of age, no one really questioned the language he used, it was normal for Celestial Dragons.

Tetsu huffed with annoyance, "Please, Alfred take me to my father."

Tetsu while walking by the flock of celestial dragons gave the celestial dragons a snarl.

It went unnoticed but Alfred picked it up.

Down the hall Alfred was contemplating on asking a question and Tetsu noticed and spoke up.

"Yes Alfred? You seem like you have a lot on your mind…."

Which was ironic because Tetsu was still kinda going crazy being thrown into this situation.

Alfred cleared up his throat, "My lord, you seem to bear hatred towards your fellow Celestial Dragons, why?"

A lot was going through Tetsu's head and so much was going on he didn't realize he wasn't acting like a "normal" celestial dragon.

'What the hell am I supposed to say? I'm not from this world and suddenly I'm here? For fucks sake I think this is still a dream….'

Tetsu new the situation was far from a dream, but it felt like everything was happening everywhere all at once.

"I hate people who disrespect others for no reason, respect is earned but disrespect is not, everyone is equal in my eyes, of course with in reason."

Alfred was once again surprised, "Young master if I may say, for your age, your wisdom is surely great."

Tetsu once again realized he was still a kid but reasoned the way he acted didn't matter, he was a celestial dragon and this was once piece, everyone was wacky and an interesting character in some way.

"I hit my head right? I think it knocked some sense into me."

Alfred chuckled but stopped immediately afraid, "Forgive me I didn't mean to lau-"

Tetsu stopped walking and looked Alfred in the eyes.

"You are my servant, my butler, and I'm hopefully considering you to be a friend, you do not need to be afraid of me, and you can laugh if I am foolish, all I ask is for you to be the best you can possibly be, and you do a good job at what you can do."

Alfred didn't say anything but simply nodded, though behind his eyes told a different story, the aura he gave off was almost one of peace rather than fear.

"We are here Young Master, do you have any questions?"

Tetsu thought for a moment, all he knew was his name but he didn't know his royal name.

He had many more questions but knowing his name before he meets his "father" was important.

"Ummm….. Alfred….what is my name..?"

Tetsu tried to play it off with an awkward smile and Alfred only sweat dropped.

"Young master, your name is Vincentius Abraham Viridis Tetsu, you come from the great Celestial Dragon, St. Vincentius Abraham Viridis, he gave you his name and your mother gave you yours."

With that Tetsu nodded and walked into the library.

As soon as Tetsu entered the room, his attention was drawn to a small, unassuming fruit resting upon a nearby table, its vibrant almost ethereal blue glowed in stark contrast to the opulent surroundings. Without hesitation, he reached out and plucked the fruit from its resting place, the fruit seemed a lot smaller than what is usually portrayed in the show.

He palmed the fruit inspecting it, he could feel the power this fruit radiated and he was tempted to take a bite.

Suddenly he heard footsteps and he quickly shuffled the fruit in his pocket.

"What do you think you're doing?" A strong and sturdy voice called out in indignation.

Tetsu immediately stood straight and a sense of fear overcame him.

But when the man laid eyes on him his furious aura ceased and his eyes went soft.

The man was built like a tank he could possibly even rival whitebeard in terms of muscles, and he didnt skip leg day not one bit.

"MY SON! HOW ARE YOU! I MISSED YOU! ARE YOU WELL?"

Tetsu's ears rang at the depth of his fathers voice and he couldn't help but give an awkward smile, it would be difficult to be in the vicinity of this mans voice.

"I...umm...im doing well..."

Tetsus father just laughed, "Still shy I see! But dont worry son when we start training that we'll beat right out of you!"

Tetsu froze.

'T-training...!? Oh fuck...this life is already killing me...my brain is going to overdose on sheer overstimulation.'

"Im going to make sure you never get hurt ever again, and the bastards that did this to you are suffering a very beautifully organized torture."

The man seemed to regret the injuries Tetsu received before his arrival into this world.

But this led to Tetsu asking a question.

"Father...what happened? I dont exactly remember everything throughly...I remember somethings...but im still lost."

St. Vincentius pulled out a chair nearby and beckoned him to sit, he took a deep breath to relax himself.

"You and your mother where on a trip to Sabody Island, and some slave worthy ingrates decided to take it upon themselves to attack you, im sure they didnt know that they attacked celestials, as your mother hates the robes and that blasted bubble helmet, but you ended up getting hit in the head and was almost pronounced dead, luckily we have the best healers in the world and they where able to fix all the damages and remove the scar."

Tetsu relaxed a little bit sitting in his chair.

'So my soul hijacked a little kids body, but honestly I feel no pity, he would grew up to be an evil bastard anyways.'

Tetsu finally settled down the first time all day, if he was really in the one piece world he would need to take advantage of every possible resource.

"Father you said I was going to be training soon right? Do you mind giving me books to read and a devil fruit encyclopedia? I want to get a head start..."

Tetsu had faith his requests wouldn't be denied, and much to his appreciation his father got up and went to a book shelf and gave him several books.

The first one was the devil fruit encyclopedia.

The second one seemed to be about haki.

And the third one was blank.

"I dont really care much for these books, but these are worth more than 500 million Berries each, the devil fruit encyclopedia is the newest addition, its the same ones the Gorosei use, and this book is on haki, its all my notes on it with detailed explanations, and this!" He pointed to the last book.

"Is yours to take notes."

He handed Tetsu the books and stood up.

"I have to go, but take care and enjoy yourself my son, your training starts in 2 weeks."

He got up and left leaving Tetsu alone.

[Tetsu N-POV](narration-pov)

As I stood up I reached for the fruit in my pocket, and took to a nearby by bed. I sat down and looked around at my room. My "room" was far to big and lonely and wasn't as interesting as this place, it was almost like a room, well a normal room at least, it had a bathroom and shower, for what ever reason a library needed a shower I wouldn't know, but honestly living in the library would help my studying and give me easier access to information, I wanted to limit as much contact as possible.

I took my attention to the fruit in my hand and the devil fruit encyclopedia.

I started to thumb through the book, around the one hour mark I still couldn't find anything relating to this devil fruit, but I knew it was powerful, I could tell from its vibe.

I simply came up with the theory that I somehow had access to a small use of observation haki, there is no other way someone could not sense this fruit.

I sensed it as soon as I came close to the library, I couldn't tell what it was but it surely had a presence.

I held the fruit closer and began jotting down an illustration of the fruit, and I drew out the shape and its details.

I stared and looked at the part of my notes underlined: Notes Of Abilities

I also left the name blank because this devil fruit was unknown.

I sighed, "Welp you only live once, and rather me have a strong fruit that nobody knows."

With that I bit into the fruit.

Suddenly I felt a sense of clarity wash over me, and then I was met with an unexpected burst of flavor that sent a shockwave of sourness coursing through my taste buds. It was a sensation unlike anything I had ever experienced, so intense that it made my eyes water and his lips pucker involuntarily.

My face turned purple but to my surprise, I found himself relishing the tartness of the fruit.

My theory is that the people of this universe must not like demonically sour fruit.

But im not from this universe and i happened to love sour foods and candies.

I savored the tangy taste and finished the rest of the fruit.

Despite the overwhelming sourness, there was something strangely satisfying about the experience, a thrill that sent a surge of adrenaline coursing through my veins.

Swallowing hard on the last bite I couldn't help but let out a low chuckle and it was a moment of pure exhilaration, a rush of excitement that left me feeling more alive than ever before.

I instinctively knew it was my new powers, it created a newfound resolve burning bright within my heart.

I somehow knew that I had the power of Will.

I immediately wrote down in my book: The Will-Will No mi.

My pen began writing furiously, and I spoke out loud my new abilities going over my notes.

"The Will-Will no Mi is a mysterious Paramecia-type Devil Fruit that grants its user the power to manipulate their own willpower and influence the wills of others. With this ability, the user can exert control over themselves and those around them, bending their desires and intentions to their whim. The fruit's power extends to the manipulation of thoughts, emotions, and even physical actions, allowing the user to shape reality according to their desires. However, like all Devil Fruits, the Will-Will no Mi comes with its own set of limitations and weaknesses, and its true potential can only be unlocked through the user's mastery and understanding of its powers."

I took a breath and close my note book and I started to experiment with my powers.

"Will Expansion: Self"

The words rumbled out of me and a soft blueish white aura formed around me, I suddenly got an idea to create a dinosaur, and an ethereal projection came out of my hand and what I thought was willed right in front of me.

I then got an idea to create clothes, a luxurious silverish baby blue silk collar neck shirt enveloped my body.

I then decided to wear a nice pair of royal blue silk joggers.

For my shoes I wore a nice pear of royal blue and baby blue Jordan 4s.

"My memories came in clutch, this fruit is fuckin awesome."

I began to play around with it more and wrote down several notes.

[Will Expansion: Self- Which applies his powers on himself and grants his will control over himself and creates ethereal projections based off of will and thoughts.]

The fruit was basically like a lantern ring, but had far more almsot godlike capabilities, and this isnt even the full potential of the fruit.

I decided the use my fruit to it best capacity.

[11 years Later- 1 year before cannon starts]

Tetsu was now 15 had decent mastery over his fruit and estimated he was about luffys level of strength during sabody.

Even though Tetsus fruit was stupidly powerful it depended on his physical strength, Haki, Mentality and Imagination.

His haki is the only reason was only at that level of strength, and he hadn't trained his body much over the years and have relied on my fruits abilities.

Tetsu got lazy.

And thats why he is in his current situation.

"COME ON MY SON, ITS TIME TO WORKOUT, NO SON OF MINE WILL BE WEAK AND SCRAWNY!"

St. Vincentius's voice vibrated Tetsu soul.

'Jesus how can one person be so loud!'

Tetsu thought as he created some ear plugs that help with his fathers loud voice, it reminded him almost of All Might and him yelling, except this man wasn't self aware.

St. Vincentius led Tetsu to a extremely large field with various weights and machines, not to far from his original life.

"Im going to leave you here for a year! If your not strong by the time I get back, Ill have garp the fist and me personally whip you up into shape!"

Tetsu sweat dropped, "Hey isnt that a little too much...Im fine the way I am, im not looking to be a inhuman monster..."

Tetsu viewed those in this world who where strong as monsters, even though he was pretty strong, he wasnt looking to do that, he just wanted to enjoy his life and watch Nika be reborn into the world.

"Nope! I am leaving now! Bye! If you're not buff like me im kicking your ass into shape!"

And with that St. Vincentius left.

"Welp...I guess I have to train...but..."

[Six months later- Tetsu POV]

I spent the first week of my training simply abusing my powers to buff me up, but it was also a mental thing so I did that while also actually training.

I did the One Punch Mans training every day and by the 6 month mark I didnt look to different from my father, I wasnt as tall, I only stood around 5'9.

I was buff kinda like Asta from Black Clover.

I reasoned I'd get taller, simply because I was 15 and a half and by the time would be 18 I'd probably be 7'5, my mom was around 7'2 and my father was 12'0, monsters I tell you.

In my original life I saw One Piece characters where tall but seeing it in real life is something else entirely.

Currently I was in the middle of writing some more note on my Haki.

So far I have intermediate level control over all three types, but for some reason I couldn't get physically stronger, I was still around the same level as before but I was definitely stronger then my pass self.

Suddenly I remembered that people in this world can only get stronger through fighting.

"Maybe thats why im not getting stronger..."

My fruit was tied to my Haki, Physical being, and Mentality, these things are also used in fights.

"Ahhh makes sense, to get stronger I actually need to fight...theory goes as far as use of application."

"THATS RIGHT, HEY SEE GARP! HES NOT AS GREEN AS YOU THOUGHT HE WAS! MY BOY IS SMART!"

I was shaken out my words and thoughts as the voice of my father made me jump to my feet.

"Jeez... can't you be any more quieter..."

St. Vincentius only laughed.

Garp looked me up and down with a squinted eye.

"The kid definitely has potential...you said you wanted to rough him up a bit...right?"

I fell onto my ass holding up my hands.

"H-hey no need for your monstrous level of training!"

The two older men just smiled.

"Well we just don't agree with you."

Tetsu could be seen running for his life.

5 months have passed and they have been "training" him nonstop.

"You wont get stronger if you keep running!"

St. Vincentius yelled while slamming a Haki charged fist near Tetsu destroying the ground under his feet.

Tetsu jumped in the air avoiding the obvious attack, but then threw up his hands to block another attack from Garp.

"You know I remember you saying that if I looked like you by the end of this year I wouldn't have to fight you...BOTH!"

Both Garp and St. Vincentius laughed.

"I planned this before you even started training my son!"

St. Vincentius flashed in front of Tetsu and sent the strongest punch he could muster, mind you both Garp and St. Vincentius are around the same level of strength.

Tetsu couldn't even intercept the punch and was sent flying into the ground.

"Ow! That hurt!"

Tetsu angrily teleported and sent an uppercut straight to his fathers chin which did nothing but slightly knock his head back.

"You might have the most insane durability I have ever witnessed, and thats coming from someone whos traded blows with that brat Kaido, but your strength still lack."

And then almsot instantly Tetsu was sent into the stratosphere.

Garp sweat dropped, "I think you hit him a little to hard..."

St. Vincentius just laughed him off.

"He's like an unbreakable punching bag, when he comes down try hitting him, honestly I havent used this much strength in ages..."

Garp shrugged and waited for Tetsu to fall.

(With Tetsu)

"Holy shit! That bastard actually sent me to the stratosphere!"

Tetsu began to rapidly fall, but suddenly began to slow down.

Tetsu started to seemingly fly.

"Yeah I can fly! Now take this you bastards!"

He began charging up his attack.

"Will Expansion: Self; Punch X100"

Tetsu flew back down at almost break neck speeds.

(With Garp and St. Vincentius)

"Hey Vince hes falling pretty fast..."

St. Vincentius shrugged it off.

"Maybe I did hit him hard... gravity is surely at work."

Both of them nodded at the logic unanimously.

Then they realized the blue dot they saw got bigger...and bigger...until a giant ethereal fist came down on them annihilating everything in the vicinity.

"Holy shit! This kids scary! What the hell was that!" Garp yelled as he jumped away.

St. Vincentius just laughed.

"Remember that fruit we stopped Roger from getting back in the day?"

Garp gasped, "Dont tell this brat has that fruit from that treasure map!"

St. Vincentius responded with a grin.

"That fruit was told to have unlimited power! Why didn't you hide it! How did he get it!"

St. Vincentius ignored him and sent a kick towards Tetsu.

"I left it lying around somewhere un my library and the kid ate it so what."

It was ironic that Garp was shocked at the lack of Common sense St. Vincentius had.

"Not even the gorosei wanted that fruit in the world...this kid is going to change the seas!"

Garp suddenly smiled, "Maybe I can turn up the heat a little bit...yiu said hes unbreakable right?"

Tetsu laying nearby started to sweat.

"N-now we could talk about this, ill give you an unlimited amount of the highest quality crackers, that not even outside world knows about!"

St. Vincentius laughed, "I already promised him that! And possibly anything he'll probably want!"

Tetsu comically with a looney toons style run.

"Hey looks he getting away..."

St. Vincentius pointed.

Garp simply just chuckled, "Not for long!"

He instantly appeared to the side of Tetsu.

"Eat this! GALAXY IMPACT!"

Tetsus world went white not because he lost consciousness, because the sheer power from Garps attack blinded him.

And it also sent him flying of the island.

St. Vincentius pointed out the obvious.

"You hit him too hard."

Garp comically yelled, "I dont want to hear that from you!"

St. Vincentius walked through the ruins of the attack to get Tetsu.

"Time to go fishing! And dont worry he wont die! He cant! Trust me we tired! His will is too strong to die or take damage! But he does have a weird weakness though..."

Garp intrigued got closer to listen.

"He is highly effected by psychological attacks, my devil fruit is actually the perfect counter to his, as I have the Fear-Fear No Mi."

Garp simply just shrugged.

"The chances of you have the perfect counter to this type of power scares me, your devil fruit already is dangerous as it is."

St. Vincentius only grinned.

"Yep! I can play on the fears of anyone."

Garp pointed out to the sea, "Lets go get your son, he might need some help."

[Chapter End]
