Luffy climbs up and stands next to Y/n

Luffy: We have come to save you Ace!!

Sengoku: Garp!! it's your damn family again!!

Garp: Luffy!!! And Y/n!!!

Marine 1: Oni Y/n...worth 500 million beli, Jinbe!!, Crocodile!! And even Ivankov of the revolutionary army!!

Marine 2: How did those two bring a whole army to this place!!

The Shichibukai are looking at them

Mihawk: So...you have arrived. Y/n and Straw-Hat...

Moria: GGRRRR!!! ONII!!!!! YOU WILL PAY FOR WHAT YOU DID TO ME AT THRILLER BARK!!!

Hancock: Y/n!! Thank goodness he is alive!!

Ivankov: Where did Croco-boy go?

Buggy: Uh....he is over there trying to attack Whitebeard!!

Buggy points to see that Crocodile was trying to attack Whitebeard

Crocodile: Its been a long time hasn't it!! Whitebeard!!

He almost hits Whitebeard until someone deflects his attack and hits him back

Crocodile: Oi...what are you doing.

The dust disperses

Crocodile: Y/n-san..

Y/n: I'm sorry. You can't touch him. Ace cares about Whitebeard-dono!

Marco looks towards Y/n with a surprised face

Whitebeard looks towards Y/n and his two swords

Whitebeard: Boy...that sword-style of yours...it feels familiar

Y/n: What ossan! You mean my two-sword style!?

Whitebeard: Why are you and Straw-Hat here to save your brother?

Y/n pauses then smiles

Y/n: Because he is mine and Luffytoro's family!!

Whitebeard: Baka!! Do you even know who and what you are even up against!!?

He angrily slams his naginata on the ground

Whitebeard: People like you would not stand a chance at all!!

The whole battlefield goes quiet after what Whitebeard said

Y/n: Oi...Ossan...Its not up to you to decide about what I can or cannot do!!

Y/n: He is the one who will become the pirate King!!

Y/n points to Luffy

Y/n: And I will be the one to defeat Kaido and become the strongest creature!! And!! I'll also take your place as Yonko!!

Whitebeard slams his naginata on the ground. But smirks

Whitebeard: You...I won't show the both of you mercy if you slow me down!

Y/n: Don't worry! I won't slow anyone down! OI! LUFFYTORO!! Lets save Ace!!

Luffy: YEAH!!

Ivankov: I-i can't believe it...

Buggy: They are standing next to Whitebeard!!

Y/n: Listen Whitebeard! We are here to cooperate with you if you do it with us!!

Whitebeard: Understandable...so are they going to execute Ace right now?

Y/n: Well, judging my calculations I don't think they will do it right now. But we should be prepared

Whitebeard: I see. Thank you for that

Luffy & Y/n: No problem!!

Buggy: WHY ARE THEY COOPORATING LIKE THAT WITH WHITEBEARD!!??

Y/n: Oi Osaan!! We are going to but using your ship

Whitebeard chuckles

Whitebeard: Do what you want with it!

Y/n: Yosh!! Let's go Luffytoro!!

Luffy: Yeah!!

They both jump as Y/n takes out his two swords.

Marco flies over to Whitebeard

Marco: You see the resemblance right don't you...

Whitebeard chuckles

Whitebeard: Both from the land of wano..both are naturally born leaders...and both use two-sword style

Marco: Could he be...

Marco: The reincarnation of Kozuki Oden?

Whitebeard: Thats only for fate to decide...

A bunch of marines make their way towards Luffy and Y/n but they are easily able to slice and punch them out of the way

Luffy: Out of the way!!

Y/n: We are coming through!!

Sengoku: Do not hesitate to kill them!!

Kizaru suddenly appears at the speed of light

Kizaru: Ohhh so we meet again huh. Y/n-san

Y/n smiles

Y/n: Yeah but you are not the main focus right now

Y/n clashes with Kizaru's light sword as Y/n slashes Kizaru leaving blood

Kizaru: So...your haki has gotten stronger huh Y/n-san

Ivankov: Death wink!!

Ivankov uses his death wink to get the both of them away

Ivankov: Keep on running guys!!

Y/n: Thanks Ivankov-dono!! See ya Bakizaru!!

They both continue to run until two marines stop them.

Y/n: Who are you guys?

Luffy: Ohh!!! It's those two!! Been a while hasn't it!!

Fullbody: Its Jango and Fullbody!! And we are here to take you guys down

Luffy: Who?

Y/n: I'll deal with them don't worry.

Y/n uses his two-sword style to slice at both of them which leaves them on the ground.

Y/n: Hmph too easy.

???: You guys are a disappointment

Fullbody and Jango: OHHH!!! Hina-sama!!

Luffy: I feel as if I know you..

Y/n: Oh...Hina-dono! Been a long time hasn't it...

Y/n chuckles as she gives him a glare

Hina: I'm not going to let you go!! I let you escape the last time!! But not this time!!

Y/n: What if we talk it out...

Hina blushes

Hina: I-I'm not falling for your seductive tactics Y/n!

Hina: Awase Baori!!

She uses her devil fruit to make a cage which surrounds Y/n and Luffy

Y/n: Aw...comeon. Not fair.

Y/n: Well...up we go!

Y/n grabs Luffy as he jumps up high enough to escape the cage

Hina: He has gotten a lot stronger since the last time I saw him...

Y/n: Bye!! Hina-dono!! Hopefully we can continue this game of chase!!

They both land on the floor as they start running again

Marine: Get them!!

A bunch of marines run towards Y/n

Y/n: Hmph these marines are too easy!!

Ace: STAY AWAY!!!!

They hear Ace shout

Y/n: Huh? Why?

Ace: THIS MY FATE!! I DID THIS TO MYSELF!! YOU GUYS SHOULDN'T BE RISKING YOUR LIVES TO SAVE ME

Ace: JUST GO!!

Luffy and Y/n are silent

Luffy: Sorry...we can't do that...

Y/n: We made a promise...

Luffy & Y/n: YOU ARE MY BROTHER!!!

(A/N): Thanks for reading!! Should Kizaru be Y/n's marine rival or should it be someone else?
