Male reader x one piece

chapter 17

You heard a loud shout from the outside of the ship...wait.

Y/n: How did I end up in luffy's ship?

You stand up but you couldn't use your candy syrup.

Y/n: Okay where is that tact located?

You heard the shouts getting louder.

Y/n: Okay what did my bro do this time?

You open the door and saw a giant mermaid and you were surrounded by a lot of fish man.

Y/n: ...What the fuck?!

The straw hats and the giant mermaid looked at you.

Nami: There you are where have you been?!

Y/n: Don't look at me I was knocked out by a fish man gaurd after he shot a seastone tack on my back and also How the hell am I on the Sunny?!

You saw the mermaid about to cry and you calm down.

Y/n: I'm sorry but I was just confused and I wasn't thinking*bows* so sorry for scaring you.

The mermaid princess was confused but wondered.

???: Um excuse me but who are you?

Y/n: Oh sorry my bad, I am Monkey D. Y/n twin brother of straw hat Luffy.

???: Oh my name is-

Fish man pirate: Attack!

Y/n: Sorry but we'll continue this later.

You jumped off the boat and head to Luffy.

Y/n: How the hell did I end up on the boat?

Luffy: Well.

(Flash back)

Zoro: Hey Luffy I found your bro!

Luffy saw an unconscious you.

Luffy: Where did you find him.

Zoro: I was trying to find the sunny but I ended up finding him in some wagon thing.

Luffy: Okay.

(Flash back ends)

Luffy: And that's how we found you.

Y/n: ... pretty explanatory.

Nami: How does that make sense?!

Y/n: Later now bro what's going on?

Luffy: Well to make it short were in a war.

Y/n: Ok, I need someone to take this seastone off me so see you when I get back.

Luffy: Okay now where were we, oh yeah!

Luffy uses his conqueror Haki and made 50,000 fish man faint.

Fish man pirate: What the?!

You can hear everyone complementing at luffy's power.

Y/n: Nice, now um can somebody find the seastone tack so I can fight as well.

Franky: Oh uh coming.

You stand still as Franky scans you and found the seastone tack while everyone else was fighting and soon he remove it.

Y/n: Thanks Franky.

Franky: Your SUPER welcome!

Y/n: Now it's my turn to show off.

Your body began to melt.

Nami: What the- what's happening to you?!

Y/n: Sit back and watch.
