Y/n was sitting next to a bloody Luffy as Nami was standing up next to them.

Nami: Y/n-kun...Luffy...

Y/n: What is it Nami?

Nami: Are you two going to just stay here? We are in the middle of enemy territory.

Y/n: And?

Luffy: *Pants* We are going to wait...

Nami: Did you two not hear what Pound said? If anyone dares to defeat a sweet general..they will be erased in a instant by Big Mom's forces..

Nami: So if you two wait then the enemies will come.. but I don't think Sanji will-

Y/n: He will. If he doesn't ill drag his ass back here.

Luffy: Sanji will come...I am going to be waiting here!

Suddenly some sounds were heard as Y/n turns to see clouds forming ahead of them

Kingbaum: Ahhh!! Ahh!!

Nami: What's the problem Kingbaum?!

Kingbaum: That mountain...is Whole Cake Chateau where Mama resides...she is in a tremendous rage!!  

Nami: There is no way all of these clouds and thunder are all from one person!!?

Y/n: Big Mom has the ability to control the weather. She is a very formidable opponent. She is a yonko for a reason.

-Timeskip-

It was currently raining as Luffy was laying flat down on the floor as Y/n was standing up and looking up at the rain

Nami: It is now raining...

Kingbaum: Its not raining...this is actually syrup 

Luffy: I wont let syrup enter my mouth...Ill only ever let Sanji's cooking go into my mouth!!

Kingbaum: Can I at least Leaf now?

Nami: Y/n-kun!! Luffy!!

Nami: Can you guys please at least hide or something!!

Kingbaum: You two dont have to stand in the same place do you!?

Y/n: If we and Luffy-dono leave then we might never see Sanji!!

Luffy: You guys can step aside if you want to!! Me and Y/n are going to take care of this!

Kingbaum: Stop this Y/n!! Luffy!! This is crazy!! Do you even know whose territory this is!!?

Nami: There is no way you two can take down this whole army!!

Luffy: I said we will wait there!! I promised!!

Y/n starts to laugh as everyone just turns and look at him

Y/n: Yahahahahahaha!! This is going to be fun!!

-Timekip-

Y/n and Luffy were beating the crap out of everyone in the army

Luffy: Namiiii!!

Galette: We were careless. I never expected you to actually come back...Y/n-kun

Y/n was in the air

Y/n: Been a long time hasn't it Galette-dono. But why do you have my crewmate in a tight situation.

Y/n looks down to see Nami being held captive by Galette

Nami: I cant take massive storms...but I can at least take advantage of Big Mom's storm.

Amande: The famed sword...

Kingbaum: No please!! Lady Amande!! You dont understand! We wood never betray Mama!!

Amande: Slow Ballad.

Amande starts to just slowly cut down at Kingbaum

Kinbaum: Please!! It hurts! It hurts!! Can you just please finish me off!!

Amande: There is no point in just finishing you off really quickly...

Amande: I only cut my enemies with very slow speeds-

Amande gets fire kicked as she gets sent back.

Amande: Who done that?!

Y/n: I did.

Amande looks up as she sees Y/n looking down at her

Kingbaum: Y/n!! You just saved me!

Amande: No way....Y/n-kun?!!

Y/n: You alright?

Mont-d'or: Are you serious!? Is this the same Oni Y/n from 2 years ago? I cant believe that you actually fought brother Cracker all night long.

Y/n: *Smiles* Well It could have been way way shorter...but I wanted to feed the captain.

Mont-d'or: You are bluffing!! There is no-

Conquerors haki just starts to burst

Y/n: What about now.

Y/n turns around and sees Charlotte Opera going to Luffy.

Opera: Cream Monster!!

The cream envelops Luffy as he gets burnt by the cream

Opera: This is the poweh of sweet cream for ya!!

Y/n: Luffy-dono!!

Y/n takes out his two swords as he uses his armament and ryou as he and Luffy run towards Opera as they try and slice him 

But as they try and slice him they somehow end up in some kind of weird dimension

Y/n: Huh? Where the hell are we?

Luffy and Y/n just look around.

Mont-d'or: Welcome...to the world of books!!

Y/n: Where are we!?

Nami: Dodge Y/n-kun!! Luffy!!

Luffy: Nami!!

The books disappear as two people come as they have their Armament haki on

???: Cream....

???: PUNCH!!

Y/n and Luffy get punched in the face as they both bleed and fall down to the ground.

Nami: Luffy!! Y/n-kun!!

Nami: Kingbaum!!

Kingbaum was kind of cut open as he was just on the ground.

Amande looks at Nami as she reaches towards her bra as she grabs out a vivre card

Galette : How do you have Mama's vivre card!?

Amanda: It has the name Lola on it.

Mont-d'or: No way?! She stole it from Lola?!

???: You got to be kidding me so they decided to kill that runaway!!

???: Oh Lola!!

???: Do you know what her last words were?

Nami: She is a friend of mine!! She gave it to me!!

Galette: Hmph. Well Mama said that she wanted all of you alive unfortunately.  Well I need you alive Y/n-kun cause I love you!

Amande: No!! I am in love with him!

Galette: Take the two of them and bring Y/n-kun with us.

Mont-d'or: Why do you want to bring that guy with you?!

Amande: Take those two away.

One of the charlotte family tries to take Luffy but Luffy stays on the game.

???: Hmm?

Luffy: I'm staying!!

The person stomps Luffy.

Y/n: Oi!! Don't you dare do that!!

Y/n blitzes towards the guy as he kicks the person off of Luffy

Amande: Get him!!

-Timeskip-

In the prison library, Whole Cake Chateau

Mont-d'or: Whoops...I accidentally closed the page. What page was it?

Galette: Page 55.

Perospero: Oh...I like the look of those faces

They were all looking as Nami, Luffy and Y/n were all in there.

Y/n: Oi! Let me the hell out of here!!

Galette: I cant...sorry Y/n-kun...

Perospero: So...Oni Y/n. We meet again.

Y/n: Tch. Silly Perospero. I swear when I get out!!

Perospero: Oh heres Mama.

They turn to see a Den-Den Mushi that looks like Big Mom

Big Mom: Mamamamama!! So we meet again huh? Oni Y/n!!

Y/n: GET ME THE HELL OUT OF HERE BIG MOM!! I SWEAR WHEN I GET OUT ILL BEAT YOUR ASS!! 

Big Mom: Mamamamama!! Still even more feisty then you were when we first met!

Big Mom: I've heard...and you also have wings as well. Does that make you a lunarian?

Y/n: Yes.

Big Mom: Mamamamamama!! I heard you were on Kaido's toppi roppo. Would you want to join my crew?

Big Mom: Mamamamamam!! You are still just a rookie even though you were in Kaido's best subgroup. If you try and come for me....you will get hurt
