4 Months Later
The streets are bustling with markets and people talking as they talking about the recent things that have been happening around the world.
Person 1: Hey you know what happened what to Crocodile?
Person 2: No I don't. What happened?
Person 1: He got defeated by the Straw-Hats
Person 2: Ohh I've heard of the up rise of the Straw-Hats and how their captain Monkey D. Luffy dealt the blow and is considered dangerous.
???: I never heard of the Straw-Hats. Are they strong?
Some Person in a black cloak appears while the two people are talking about the Straw-Hats.
Person 1: Um.. Y-yeah they are quite strong since there is a lot of them
Person: Y-yeah definitely
???: Ah okay then. So they might be weak
The person mutters under their breath as they walk off with the two people they were talking to sighing in relief that the person is gone. But then marines start running around and questioning everyone as they reach the two people.
Marine Officer: Excuse me but you wouldn't have happened to have seen him would you?
The marine officer then shows a poster of the person they are looking for.
Person 2: Y-you mean Oni Y/N worth 150,000,000 million?
Person 1: Yeah I haven't seen him around anywhere here.
Marine Officer: Okay thank you for your time. He's not here boys! Split up and find him
As the marine Officer walks away while clutching the wanted poster in his hand.
The person continues to walk along the paths of Water 7 as they look around at the complexity of just everything around them.
???: This place truly is Amazing. I've never seen anything like it
As they continue to walk forwards, they bump into some orange-haired girl as she is talking to the two people next to her.
Nami: Whoops Sorry about that
???: Yeah you better apologise for that.
Nami however doesn't let that slide as when she walks back she turns back to face him.
Nami: What did you say to me?
???: I said you better apologise. Is there a problem?
The person walks up to Nami as Nami stands her ground.
Nami: Why am I apologising. I'm not going to do that
???: Well I think you should
As the person and Nami get into a fully blown argument as the two people next to Nami try to calm her down.
Usopp: Nami calm down there is no need for tension
Luffy: Yeah just please calm down
The person looks to see that the last person that spoke was wearing a Straw-Hat.
???: Wait? could that person be..
As he is about to finish his sentence, Marines start to run towards where they are.
Nami: Marines! I guess we gotta leave that person...wait Where did they go!
As Nami starts to look around as she realises that the person must have teleported away.
Marine Officer: I know you guys are the Straw-Hats but we have bigger fish to fry. Have you seen this person
As they show Usopp, Nami and Luffy the bounty poster of Y/N.
Luffy: I've heard of him but I've never seen him before
Usopp: Same. What about you Nami..Nami?
Usopp looks at Nami as he finds her just staring at the picture of Y/N to the shock of the two.
Nami: Nope I have never seen him before but he looks cute. Very cute
As Nami starts to drift from her words as she continues to look at the wanted poster before the marine rolls the poster back up again.
Marine Officer: Thank you for your time.
The Marine Officer and his crew walk off as Usopp and Luffy just look at Nami.
Luffy: Lets go and exchange our money
Nami: O-oh yeah the money. I almost forgot Yeah let's go and do that
As they start to walk off to the area where they are able to exchange the gold for money from Skypiea while Nami is still thinking of Y/N.
Meanwhile, the Black robe figure stops at a alleyway where he takes off their hood for the first time.
Y/N: Damn I could have almost got caught by the Marines not once but Twice!
Y/N reveals himself as he takes off the hood of the Black robe.
Y/N: Hmmm What to do what to do? should I go beat up those Marines? Nah too risky that would end up being really bad. Whatever I might just go to sleep since I am tired.
As Y/N goes into the place that he is staying in and goes straight to bed.
4 Days Later
Y/N wakes up fully revived and ready for the day as he sees that everything around him has just crumbled as all the buildings are crushed.
Y/N: What in the world just happened?
Y/N sees that a building is going to fall on him as he uses his Kanabo to crush the building completely.
Y/N: I gotta get to higher ground. I guess I gotta fly.
Y/N then transforms into the dragon form of his fruit as he begins to fly up towards the surface..
At the Bridge
Zoro: Looks like Luffy made it out of those two buildings aswell
Paulie: That guy truly is Amazing
Chimney: Big Bros you two are amazing!
Kokoro: I guess now we gotta find out way to Enies Lobby.
Galley-la Worker: Thats true Kokoro-san. How are we going to get there
Nami: Its not like we can fly or anything
As Nami says that they hear tremors and shaking noises as everyone is on the bridge as it starts to shake.
Luffy: What is that noise!?
Luffy holds his Straw-Hat as they all just witness a Dragon just appear from under the bridge as it just looks over all of them.
Gallery-la Workers: What is that!
As everyone just looks up in fear to see a full scale dragon in front of them.
Y/N: Oh sorry didn't mean to scare you guys. Hold on lemme just get out of this form
As Y/N flies towards them as he detransforms from his Dragon Form into his human form.
Luffy: W-wait you are..
Y/N: Yeah. I am the Oni Y/N at your service
Nami: Y-y-you! You are the one that I bumped into
Y/N walks closer towards Nami as she just starts to turn red while looking away
Y/N: Oh its you. I'm still waiting on my apology you know.
Nami: Well..I ain't apologising then!
As Nami tried to hit Y/N but her punch gets easily caught by Y/N as he moves closer to her face.
Y/N: No need to do that was there!
As Y/N just smiles at Nami. Her response is to quickly back away from Y/N
Nami: W-w-well I guess there was..
Nami starts to stutter a lot as Y/N starts to laugh
Y/N: And you two are Monkey D. Luffy and Roronoa Zoro. I thought I would see Sanji here but I guess he isn't here.
Zoro: You know us?
Y/N: I've heard of your existence ever since you guys defeated Crocodile. I must say I am impressed
Luffy: Well Thanks Y/N! Why don't you join me crew
Y/N: Nah I would rather fly solo. But I will be willing to help you get your friend back
Chopper: H-how did you know that
Y/N begins to walk over to Chopper as he pats him on the head
Y/N: I know a lot of things.
Nami explains to Zoro and Luffy about what happened to Robin and how Sanji was able to catch up to them.
Luffy: So we have to find a way to set sail and go after them
Zoro: But how we going to do it.
Everyone starts to look at Y/N who was just sitting down focused on his Kanabo.
Luffy: Y/N? Would you mind carrying us to Enies Lobby
Y/N: Nope. Can't do it.
Nami: Why not huh.
Y/N: I can barely use the Dragon Form to fly so Unfortunately I can't do that.
Luffy: Rope Guy! could you lend us a boat by any chance.
Paulie: There is only one sea train left. The Puffing Tom. But its dangerous out there! The weather gets very choppy.
Galley-la Worker: Yeah! It's like riding into your own death
Paulie: Also Aqua Laguna barely cause this much damage other times, so it's a problem now.
Y/N: Don't worry. With me there It will quite easy and also I already know how Enies Lobby works.
Zoro: How?
Y/N: I allowed myself to be captured so I could look around Enies Lobby well I took down the marines then went to explore!
Nami: How stupid can you be! Why would you do that
Y/N: I dunno. I was bored so I just did. And why do you care
Y/N looks at Nami as Nami just looks at him in frustration.
Nami: No reason Idiot
Y/N: Huh!?
Y/N: Listen here you.
As Y/N angrily approaches Nami but is stopped by Zoro and Luffy.
Zoro: Just relax
Y/N: Alright.
Kokoro: Hold on!
As everyone looks towards Kokoro
Kokoro: You guys really need that ship to get to your friend and save her.
Everyone except Y/N: Yeah!
Kokoro: If you are happy to put your life on the line for her. Then I will go and start up the Sea Train for you.
Everyone in the Straw-Hats are very happy when Kokoro says that which confuses Y/N a little.
Y/N: They are willing to put their life on the line for the safety of a crewmate.
He Chuckles
Y/N: Intresting Bunch.
Y/N stands up while swinging his Kanabo to put on his back as they all look at him.
Luffy: Whats up Y/N
Y/N: I've decided that I want to join you guys on your little rescue mission. I wanna face some strong opponents and if we do rescue Nico then you have to apologise.
Y/N points at Nami still pissed on what she said
Nami: Sure.
Luffy is excited to hear that Y/N is om the crusade to get Robin back
Luffy: Now we have more fire power so it's going to be easier for us to get her back.
Y/N: Alright let's go then.
They start to walk towards where they can find the Sea Train but they get interrupted by a bunch of people.
Y/N: Uhhh Who are they?
Zoro: They are the Franky Family. The quote on quote 'Family' Of Franky.
Y/N: Ah okay
Zamba: Straw-Hat! Please I am begging of you! Take us with you! We want to save Bro!
Y/N: But you are going to be going up against some tough opponents
Mozu: Please just let us! We would throw our lives for Bro!
As all of the Franky have the same kind of response in their eyes as Y/N just looks at Luffy.
Y/N: Your call.
Luffy: Hurry up and Get on!!
FF: Straw-Hat!!
Zamba: We will attach our bull to the train. I thank you so much!!
Kokoro: I guess the morale has increased. Ready to go.
Luffy: Yeah!!
As Kokoro starts the engine up as the train slowly starts to move before it accelerates as it leaves the canal.
Luffy: Hold on to something!!
As everyone holds onto something but Nami latches onto Y/N.
Y/N: Hey. I'm not some post you can't just be doing that grab onto someone else Idiot.
Nami: Be quiet. You just feel safe..
She mutters the last part to herself as the train keeps accelerating as it goes onto the rails.
Y/N looks around and sees Chopper sleeping which acting as if he was Y/N which makes Y/N smile but he hides it from the others.
A/N: Thanks for reading! I skipped a lot of the arc because I don't think Y/N would have been relevant. Also, who should be Y/N's Main Rival. Comment it down!
