One Piece: The Demon of Fire

"The World Government is too extremist!" Said a black-haired man indignantly.

"Yes they must have already sent their dogs to kill us" Said a bespectacled man in a white coat.

"Roche don't say that, a marine is the one who let Olvia escape" Refuted an old man to the bespectacled man named Roche.

"But they killed everyone else Clover-san!" Roche said in a sad and angry tone.

"W-what shall we do..." Whispered a blonde woman in despair.

Leo listened to this fierce conversation as he slowly opened his eyes without understanding what was going on.

*Ugh... Where am I?* thought Leo confused.

*What happened to me?*

Out of nowhere confusing memories stuck in his mind like a thousand needles as fragmented images quickly wove themselves into his head.

*Ugh it hurts!* thought Leo painfully, as he grabbed his head and assimilated all the new memories.

*Wait... I transmigrated to the world of One Piece and took the body of an old man named Fudo Yamamoto?* He thought incredulously.

Ohara Island in the West Blue, the World Government already suspected that the archaeologists on this island including him, were researching about the Void Century so it was a matter of time before they murdered them all.

Also, without these memories, Leo remembered the event of Ohara's destruction in the anime, although he didn't remember the exact details with the new memories they were no longer needed.

Meanwhile, the memories kept coming to him...

This new body was an old man with the appearance of Yamamoto from bleach, he was an archaeologist all his life and now he was present at the event of Ohara's destruction.

*Of all places send me here...? In the body of an old man who is at death's door* Leo thought in disbelief of his bad luck.

Also from the memories of the original body, he knows that this old man is very weak and never fought in his life.

*Wait... I have Ace's mera mera fruit!" thought Leo a little happier as a memory of the original owner eating the fruit came back to him.

*Although I doubt I can beat a buster call...* Leo thought discouraged.

Besides, the original body doesn't even have any combat experience, nor did it ever practice with this fruit, it just happened to find it and wasted it.

*What will I do...* thought Leo as he looked at his shriveled hand.

Ohara Island was facing an unprecedented crisis and he was just a weak old man with a group of weak archeologists against 10 marine ships and 5 vice admirals.

Leo closed his eyes and forced himself to calm down. At this moment, he had no choice but to completely accept Fudo Yamamoto's memory and body.

DING!

As he calmed down he heard the sound of a bell in his mind, as he opened his eyes he noticed a window in front of him that read:

[ Initiating merit system…

Inserting template of Shigekuni Yamamoto Genryūsai.

10%... 30%... 50%... 75%... 95%... 99%... 100%!

Congratulations host the template has been successfully uploaded and the merit system is officially activated ]

"Huh?" Leo's heart trembled.

*Finally here's the catch!* Leo thought excitedly.

Seeing the name of the template he currently possesses his heart trembled faster.

*Yamamoto Genryūsai... one of the most powerful people in the world of Bleach even anime...* Leo thought with a smile on his wrinkled face.

*System open status window...* Said Leo in his mind a little doubtful if this would work.

The system as he commanded opened the menu and a pale blue interface appeared in front of his eyes.

]

Leo's previous smile faded changing it to a grimace and widening his eyes.

*3 days to live? I can handle the fact that you sent me to an old man's body, but what are these weak stats?

Also, he noticed that the progress of his template was extremely low so he was still in the same situation as before.

*What was the person from the original body doing...?* Leo thought as he looked at the devil fruit mastery stats.

The original host of this body had so many years of fruit and only got 12 points at the beginner level, totally wasting the potential of this fruit.

Leo saw the unusual statistic called Spirit Power/Haki and pondered for a moment.

*I guess it's spiritual power or something...* thought Leo.

The spiritual power or known as Reiryoku in Bleach is the amount of spiritual energy that a being has stored in his body or soul, through this you can use techniques such as Kidō which are advanced spells. In the case of the world of One Piece, the haki is the same, the ability to sense and use spiritual energy and can be used through the haki of observation or weaponry. They are simply different ways of using spiritual energy.

He assumed that the original Yamamoto's Spiritual Power abilities will be unlocked as he progresses through the template.

As for the observation and weapon haki, he will have to find out how to train them on his own, as Yamamoto's template does not know the training method. On the side of the conqueror Haki, he should check if his current body possesses such power, although, in the bleach world, there is Reiatsu which is a power with some similarities.

So, if he doesn't possess it in this body, he doesn't care much about it.

"Grandpa Yamamoto you woke up!" said the blonde girl as she approached Leo who was not far from where the conversation was happening.

Leo looked at this young blonde girl and remembered that her name was Hocha one of Ohara's archaeologists and his granddaughter.

"Grandfather ¿what shall we do? The Marines should be here any minute" Hocha said fearfully.

Hocha was raised by Yamamoto, the previous owner of that body rather. So whenever she was in trouble she relied on her grandfather who was one of the most respected archaeologists along with Clover.

Clover was the director of the Ohara Library which is where they are currently located, and an authority on archaeology.

DING!

[A prerequisite task of the main mission is activated: Drive back the enemies. Protect your home island and its citizens from the evil marines by teaching them a lesson]

[Detecting that the host is too weak. A beginner's packet is awarded Do you want to open it?]

*Open it* Leo ordered in his mind quickly regaining some hope.

[You have received 1x Life Card and can recover 1 year of life.

You have received a 5x Critical Block Card, which can block 5 fatal attacks toward the host (passive).

You received 3x Semi-complete strength cards. Will give you 30 minutes of 50% of Shigekuni Yamamoto Genryūsai's strength]

*These things aren't bad at all...* Leo thought with a slight smile, as he looked at his status again in which a new sale appeared.

[Name: Fudo D. Yamamoto

...

Items: 1x Life Card, 5x Critical Block Card and 3x 50% Strength Card Yamamoto]

"Grandpa are you alright?" asked Hocha somewhat worried when she saw that Yamamoto was not responding.

*I guess I'll be called Fudo D. Yamamoto from now on* Leo thought trying to leave his name behind.

He noticed the letter D, but he didn't have time to think about such things yet.

"I'm fine, don't worry I'll take care of it" Yamamoto said in a calm and kind tone as he got up from his chair and walked over to Clover and the others.

Hocha was one of the closest people to the previous owner, and taking in his memories felt an attachment to her.

"Fine..." Hocha said a little calmer but a little hesitant.

"Old man what's the situation?" asked Yamamoto to Clover.

He called Clover that, since from his memories he realized that he was his best friend and they had great trust.

"Oh old man you finally woke up from your nap" Clover said with a slight smile seeing his friend.

"Olvia knows the situation better ask her" Clover added as he looked at the white-haired woman.

*That's... Nico Robin's mother* Yamamoto thought as he finally saw a familiar anime character.

Although he remembered something about Clover, if it weren't for the memories he wouldn't even know his name, let alone the other archaeologists here.

The only recognizable characters to him from the Ohara event were Nico Robin and her mother, Nico Olvia.

"Yamamoto-sensei a couple of days ago a vice admiral let me escape and I got here, so they shouldn't be long in coming" Olvia replied in anguish.

Olvia had left the island two years ago to go to investigate the poneglyphs, she left with 33 archaeologists who were killed by the marine, only she survived, but she was captured by them.

She managed to escape thanks to the help of Vice Admiral Saul, a giant from the country of Elbaf and arrived a few days ago in Ohara to warn the other archaeologists about the World Government and the marine.

"Mm" Yamamoto nodded calmly as he scratched his beard.

He noticed that despite this situation he was very calm and clear-minded, he deduced that this may be thanks to Yamamoto's template that although this at 4.7% was inserted into him and he felt a different sensation in his body.

*Well it's time to teach those arrogant marines a lesson... but first* Yamamoto thought as he reopened the system status.

*Use the life card* I mentally ordered.

This was what he needed most now as he had almost no life force.

The system did not respond, but the life card broke into many pieces, and motes of light shot out of it and headed toward his body.

The motes of light entered his body, and he instantly began to notice the great changes that were happening to him.

His skin changed, his hair changed, his eyesight became clearer and his life force was being restored.

Yamamoto looked at the system menu, noticing that his lifespan was increasing steadily.

Finally, after adding 1 year of life it stopped, making him now possess 1 year and 3 days of life.

*What an amazing feeling* Yamamoto thought as he noticed the effects.

Olvia who was looking right at Yamamoto noticed something strange and new about him.

Just as she was about to ask him what happened to him, a scream was heard coming from outside the Tree of knowledge.

"Listen Ohara demons! You're surrounded! Come out quickly and face justice!"

"Damn it they're here!" cursed archaeologist Roche.

"Grandfather..." Hocha said in a fearful tone as he looked at Yamamoto.

Everyone else had ugly looks even Clover, but none of them wanted to leave and let them destroy the research they dedicated their whole life.

*I won't be able to see Robin again...* thought Olvia depressed knowing what her destiny was.

Just as Yamamoto was about to speak, Clover beat him to it and said:

"Come on, the only thing we can do is to tell the truth and be judged fairly" Clover said as he walked out of the library.

The others nodded taking courage and followed him.

At this, Yamamoto shook his head, but still followed his old friend in silence.

*They've already killed 33 archeologists, I doubt they're being fair..." Yamamoto thought as his resolve to protect the archeologists and their research grew.
