Getting to know the Straw Hats

The two years passed quickly and the day of the Straw Hats' reunion arrived. Me and Luffy went to Sabbody Island which is the meeting place. I only took my two swords and Luffy is carrying a large backpack of food that Hancock gave.

Arriving in Sabbody, Luffy and I are using a disguise that Hancock gave to both of us, honestly I thought the disguise didn't help, but to my surprise my surprise worked.

During the search for Luffy's crew we met people posing as Zoro, Sanji, Franky, Robin, Usopp, Nami and Luffy. Luffy used King's Haki and put the fake people on the ground.

However, after a few hours of searching we came across the copy of Zoro and Sanji and Luffy thought they were his friends, I obviously knew where this was going and that's why I didn't say anything. We are taken to a very public area and the man using the name Luffy goes on a tirade.

- We've already found one of the criminals who insulted me! Are they! - Said the fake Luffy and I just got a bored look on my face.

- Hey, if you want to do a good show, do it soon. - I say this letting out a yawn that made the fake Luffy get angry.

- Why you! - Said the fake Luffy grinding his teeth.

In short, the show continued until the Navy arrived, surrounding all the pirates and the fake Luffy ordered the use of a spy sailor to escape, but shit went wrong and chaos broke loose.

- You idiots, listen to me! - Fake Luffy shouted in fear.

- Huh? Why are they calling me leader? - Luffy said, not understanding anything.

- Luffy, are you noticing any difference in Zoro and Sanji? - I say that and Luffy looks at fake Zoro and fake Sanji.

- I don't see anything wrong. - Luffy replied and I let out a sigh.

The chaos continues between pirates and the navy and the situation worsens when the Pacifistas appear shooting beams of light at the pirates. This scared the vast majority of pirates around.

- The Werebears! Hancock told us not to get in trouble... - Luffy said and I let out a small laugh.

- I don't think this will last. Let's bet, if we get in trouble, I'll keep half the food and if you win, you'll keep mine. - I say this with a smile knowing that I will win.

- Deal! - Said Luffy.

Meanwhile the fight is going on and the impostors tried to escape, but they ended up facing Kizaru's nephew who soon exposed the true identity of the impostor Luffy who is called Domaru Black. Luffy was surprised to learn the truth.

- So he was impersonating me?! - Luffy said and let out a sigh again.

- Luffy how many times do I have to tell you to stop having a banana head?! - I say this getting angry at Luffy's stupidity.

- This isn't my fault! I really thought they were my friends! Another thing is I don't have a banana head!!! - Luffy shouted, not liking being called banana head.

- Since when did Zoro look like a drug addict, Sanji having afro hair, Franky being thin, Usopp being tall and fat and Nami looking like Pigtails!!! - I say this with our heads touching each other.

While we are arguing like two idiots, a Pacifista shoots in our direction, Luffy and I noticed this and dodged without a problem, but our disguises were not lucky and because of that everyone saw our faces.

- It's Straw Hat and the Green Devil! - People shouted.

- Luffy, I think we were discovered. - I say this in a neutral tone

- Did we wear a disguise? -Luffy said, forgetting the disguise he was using seconds later.

- Straw hat! Green Demon! - Kizaru's grandson shouted.

- Oh, it's you! Are you going to try to stop people? We can't get into trouble! We want to leave in peace! - Luffy said and I got a smile of victory.

- I won Luffy. - I say this looking at Straw Hat and he looks disgusted.

- Damn it! - Luffy shouted in anger because he lost the bet.

- Do not worry! You won't even raise the sails! The situation has changed over the last two years. Now I'm a naval officer. - He said and I whistle and clap my hands.

- Good for you, do you want a sweet as a gift? Not to be an asshole, but I literally fought the admirals alone. - I say this leaving the sailors afraid.

- PX-5! - Shouted the officer and the Pacifistas shot at both of us, Luffy and I dodged the shots and Luffy soon destroyed the robot in one blow.

After that we both started running away from the navy and while escaping we heard Zoro's voice.

- Hey, Luffy! - Shouted Zoro

- Luffy! I knew it was you! Why do you keep getting in trouble?! - Sanji said.

However, they are interrupted by a Pacifista, Zoro and Sanji destroy the robot very easily.

- Luffy, you were the no- Zoro stops talking when he sees me.

- Look, it looks like someone finally shut you up. Another thing Luffy who is he? - Sanji said.

- He's a friend of mine. I'll introduce him when everyone is together. - Luffy said and the four of us started to run away with Zoro not stopping staring at me.

Along the way, Luffy and I stopped running and called Reyleigh, shouting that she was watching us.

- I came to check on you, but it looks like everything is resolved. You are clearly stronger. Now go back to your companions! - Reyleigh said with a smile.

- Reyleigh! Thank you for everything these two years! - Said Luffy.

- Thank you very much too Reyleigh! I owe you one after your teachings. Make sure you don't die until we win the world! - I say this with a smile.

- Reyleigh! I'll make it! I'll be the king of pirates!!! - Luffy shouted his iconic phrase. And with that we headed back towards Luffy's Ship.

****************

Narrator's view

****************

Reyleigh sees his students leaving and exploring the new world and he remembers the two years he spent with them, they were two good years for him.

But what shocked him for a moment was that he saw two silhouettes forming behind Luffy and Saito.

It is the silhouette of his former captain and best friend, Gold D Roger and Roger's rival and friend, Edward Newgate. Seeing his old companions made him burst into tears.

- Heavens.... That's too much emotion for these old eyes. It looks like you've already chosen who will inherit your legacy. - Reyleigh said with a happy smile.

- Get to the top!!! - Reyleigh shouted to his students.

Saito's vision

**********

The escape continues with the Navy on our tail and in front of us there was a fleet of soldiers, but they all became depressed when several ghosts passed among the soldiers.

- Wait, that's not it! - Sanji said, remembering who he is.

- I knew it was you who were up to no good! I don't believe! That you haven't gotten anywhere yet. - Said a girl with pink hair wearing a gothic dress as well as one for the sun.

- Oh! I know you in Thriller Bark! - Said Sanji in his cattle mode.

- Who is she? - Me and Luffy spoke together.

- What are you still doing here? - Zoro said being rude.

- Don't talk to me like that! I was the one who brought you here! If it weren't for me, you would be lost on the island! Put yourself in your place! - Said the Girl, but she is scared by Sanji, smelling her from behind.

- A real woman! A real woman! - Sanji said in total trance.

- Of course I am! What disease do you have! Anyway, get out of this place soon! I saw navy ships around. Soon they will surround the island. - Said the ghost girl.

- That's really bad... But I have a problem. I can't get out of this position. Real women are awesome! - Said Senji, going to jump at the girl who immediately counterattacked using her ghost and kicked him in the face as a bonus.

💭I know Sanji is a pervert, but seeing it in person and knowing what he went through makes me feel sad. Living for two years on an island that only has Drags is truly hell.

At that moment a bird appears with Chopper riding it. He came to get everyone to go straight to the ship, but Zoro's action took me by surprise.

- The others will wait, I have something personal to deal with. - Zoro said seriously.

- What do you mean Zoro? They are all waiting for you! - Said Chopper.

- I know that! But I won't go back until I fight him! - Zoro said looking at me.

💭Not that. This is not good at all.

- Hey you stupid Swordsman! This is no time for your crazy things! We have to see Nami-san and Robin-san. - Sanji said, getting up from the ground.

- Shut up, pervert chef! Luffy and you guys go ahead, I have to do this. - Zoro said, taking out his katanas.

- You can go ahead Luffy, Sanji. Don't worry, we won't take long. - I say this already knowing that there is no point in arguing when Zoro is like this.

Luffy was quiet for a few seconds until he let out a smile and responded.

- Ok! Go easy on Zoro, Saito! - Luffy said, taking Sanji by surprise.

- Luffy! You are crazy?! - Sanji said, not believing what he heard.

- Trust me. Saito is a good person, he won't hurt Zoro. - Luffy said, climbing on the bird, taking Sanji with him.

With that Zoro and I are alone and he doesn't stop looking at me seriously as if he were analyzing me.

- Are you going to stare at me or are you going to say something? - I say this feeling uncomfortable.

- I don't believe it's you. - Zoro said, leaving me confused.

- Be more clear please. - I say this in a relaxed tone.

- I don't believe that you are the new strongest Swordsman, but I find it very difficult that Mihawk would lie and say that he is going to retire. - Zoro said, leaving me speechless.

💭 Wait, wait! Zoro dreams of being the strongest Swordsman! To overcome Mihawk. But I literally defeated Mihawk and I have his sword as a bonus..... I fucked up Zoro's life!!!! I'M SO DUMB!!!!

- So you want to test me if what happened is true? - I say this sounding serious, but inside I'm cursing myself.

- Exactly and as we have little time, let's start being serious. - Zoro said, already putting Haki on his katanas.

💭HE REALLY WANTS TO START BEING SERIOUS?!

- Are you sure about that? You may regret your choice. - I say this sounding serious with a shadow covering my eyes.

- Show your full power. Green Demon. - Zoro said with a smile and in response I take Yoru off my back and Zoro is surprised to see her scarlet blade.

- I'll give you some advice, Zoro. Be careful what you wish for... - I say this appearing in front of Zoro, not even letting him respond.

Zoro is scared by such speed and he attacks, but it was just a silhouette of me. Zoro feels a very dangerous presence behind him that makes all his instincts scream saying: "Run". But the moment he looks back, he sees me preparing to cut off his head and his brain can only register one event which is:

DEATH.

However, fate was kind to Zoro and I stopped my attack at the moment Yoru was glued to his neck, but the impact occurred behind him, releasing a very loud sound that everyone on the island must have heard. Zoro just looks at me in total shock and I just look at him with a serious look, but then I put Yoru behind my back and smile.

- Well, I won. Shall we meet the other Zoro? - I say this as if nothing happened seconds later.

- Y-Yes.... - Said Zoro who looks back and he sees all the trees on the island cut in half, even the clouds in the sky were not spared.

- Green Demon.... - Said Zoro.

- Yes? Another thing,my name is Saito. - I answer

- Can I be your student? - Zoro said, leaving me perplexed. - What? - I reply, I don't understand anything.

- Y-You want to be my student.... - I say this wanting it to be a lie.

- Yes. You defeated me. Furthermore, Mihawk said that if I'm going to get stronger, I have to ask for your help. - Said Zoro.

💭That son of a bitch! He threw the problem at me. I don't want to teach Zoro, he's already learned enough.

- Are you sure about that? - I say that.

- Yes, Sensei. - Said Zoro and I get irritated at being called "Ssnsei".

- Don't call me Sensei! - I say this shouting.

After that, Zoro and I were the last ones to arrive at Luffy's ship and I met up with the rest of the Straw Hats.

- Oh! You arrived. - Luffy said with a smile.

- Luffy. Who is he? - Nami said looking at me.

- Ah, he's someone who helped me a lot in Marineford. - Said Luffy.

- He is also my Sensei. - Said Zoro. - How many times do I have to say that I'm not your Sensei! - I say this getting angry.

- Guys, I want you to meet our new crew member. Saito Tatsumaki. - Luffy introduces me leaving Nami, Usopp, Chopper, Zoro, Sanji, Franky and Brook shocked only Robin is without much reaction.

Everyone except Robin: YOU BROUGHT A YONKO TO YOUR SHIP?! LUFFY ARE YOU CRAZY?!

- What? A Yonko? What is this food? - Luffy said, not understanding anything.

- A Yonko is an emperor pirate who is considered the strongest pirates in existence and Saito Tatsumaki or Midori Akuma (Green Demon) is seen as the fifth Yonko. - Robin explains and I get a little confused.

- But the Yonkou don't have territories? I don't remember making one. - I say that and Robin responds.

- Some people say your territory is in Alabasta. - Robin said, leaving me surprised.

💭Oops sorry about that, Vivi wasn't my intention. I hope she's not too mad about it.

- I only went to buy a sword, not to dominate a country. - I say that.

- I still can't believe we're going to have one of the strongest pirates with us. - Said Chopper.

- I think this is very Super!!!! - Franky said, posing.

- I don't see a problem with that after all he helped Luffy-san. - Brook said.

- For some reason, I feel more confident that we are going to be okay on this journey. - Usopp said.

- Once again Luffy did something without thinking. It seems like two years haven't changed anything about him. - Nami said, letting out a sigh.

- I think things will get more interesting with him together. - Robin said.

- That's our captain. Look kid I feel sorry for you having this idiot as a student. - Said Sanji and soon after, Sanji and Zoro started fighting.

With that done, Nami gave instructions on how the ship was going to submerge and during that Franky finished the preparations and Brook and Zoro were going to release the sails, but before that happened, Luffy had to give the orders.

- Guys! I have a lot to tell you, but thank you for accepting my selfish decision two years ago! - Said Luffy.

- That wasn't the first time. - Sanji said.

- So it is! You just look at your navel. - Usopp said.

With that, the ship begins to submerge and we are about to leave on our way to our destination.

- Let's set sail!!!! Let's go to Fishman Island! - Luffy shouted and the ship already entered the bottom of the sea.

To be continued.....
