Y/n, Momonga, Hancock and Luffy all make their way towards the underwater prison

Y/n: This place is amazing. And heavily guarded

Momonga: Thats right..because apparently two people have escaped this place in under a year

Y/n: Really? They must have been some sneaky pirates

Momonga: Indeed they were.

Momonga turns to Hancock

Momonga: And regarding your request to see Portgas D. Ace..pirates are normally forbidden to enter here. But you can if you wear Seastone cuffs and a body check...

The marines' noses behind Momonga start to bleed

Momonga: And we can't have the risk of any prisoners escaping

Hancock: If you must..

The gates of the prison open as they all enter

A man walks up to them to greet them

???: Welcome to Impel down!

Hannyabal: My name is Hannyabal! The vice-warden

Momonga: Nice to meet you

Hannyabal shakes the hands of Y/n and Momonga

Hannyabal: Me and head jailer Domino will be guiding you today since Magellan is on level 4!

They all walk over to the body checking rooms

Y/n: Sir! I will be looking for the warden!

Momonga: Okay. Do you know your way around this place?

Y/n smiles then nods

Momonga: Very well, go through the body check first

Y/n: Yes Sir! And good riddance

Y/n walks into the body check room

Y/n: So you are the one that will be doing the body check on me..

Y/n: I must say you are quite the catch..your name is

Domino: D-domino is my name

Y/n: My name is Y/n

Y/n just smirks at her which causes her to blush

Y/n: You see...

Y/n starts to walk closer to Domino

Y/n: You are going to pretend that you done the check and I left...

Y/n: Are we clear?

Domino: Y-yes Y/n-kun

Y/n: Yosha! I knew I could count on you Domino-dono!

Y/n hugs Domino

Y/n: Okay see you around Domino-dono!

Y/n jumps up to the roof removing his marine clothes

Domino: O-o-okay Y/n-kun..He is so HOT!!

Domino goes red then drops to the floor

Hancock: Its safe to come out Luffy-san

Hancock makes her way into the room and sees Domino on the floor

Hancock: What happened?

Luffy: Oh! It must have been Y/n doing the thing that he does best..

Luffy: Anyway thanks Hammock!

Y/n and Lufdy meet up on the roof

Luffy also hops onto the roof aswell

Luffy: Did you thank Hammock?

Y/n: No. I didn't actually..

Y/n peeks down from the roof and sees Hancock, Domino, Momonga and others in a elevator

Y/n mouths the words 'Thank you!' and gets back up to the roof

As Y/n says that both Hancock and Domino go red and just faint as the elevator goes down

Luffy: Yosh! Where do we go from here?

Y/n: We should go down!

Luffy: Alright then!

Timeskip

Y/n and Luffy quickly make it to Level 1 as they now are just roaming the area.

Y/n: Now we just need to find the place to go down a Level

Luffy: Alright.

Prisoner 1: Oi! How did you guys get outside?

Luffy: We came from the outside.

Y/n: Do you guys know where Ace is being kept?

Prisoners: Ace!?

Prisoner 2: You mean Fire Fist Ace? The one that got beaten by BlackBeard and the Dark Eye?

Y/n: Who the hell is Dark Eye?

Prisoner 3: A member of the Blackbeard Pirates. The second strongest.

Luffy: Please we need to know where Ace is!

Prisoner 1: He is in Level 5

Y/n: Level 5 huh? I know how to get there! let's go!

They start to run but hear screams

???: HELPPP!! HELP!!

One of the prisoners is being chased by some creatures

Y/n: What are they?

Prisoner 3: AHHH! BLUGORIS!!

Prisoner: They will kill you if you get too close!

Y/n: So how come he isn't dying?

The Blugoris slice the person but he continues to run

Y/n: Oi! Do you need help!

Luffy and Y/n run towards the person

???: I Can't run because they cut me!! Bur it's not over!!

His body parts reattach as he looks to Luffy and Y/n

???: GYAHHHH!!! ITS STRAW-HAT AND....AND.. who are you?

Y/n: My name is Oni Y/n. Luffytoro you know this clown?

Luffy: Yeah that's Buggy

Buggy: Did you guys get caught as well?

Luffy: Nope! We came in on our own

Buggy: BAKA!! WHAT KIND OF PERSON DOES THAT!?!?

Y/n: You guys...friends?

Luffy/Buggy: NEVER!!

Buggy: I had a plan called 'Buggy sneakily escapes' BUT YOU RUINED IT!!

Luffy&Y/n: NO WE DIDN'T!!

Buggy: We might as well make a new plan called 'Uprising'!!

Y/n: Now that sounds better!!

They all target a Blugoris and beat them down to a pulp

Buggy: Free the Prisoners!!

Y/n: Baka! Don't order me around!
