The Straw-Hats, including Y/N have escaped the grasps of the hero of marines as they are now just sailing.

Luffy: Oi! Usopp! I caught one!! Help me reel it in.

As Usopp runs over to where Luffy is and helps him to pull up the giant shark that they have caught.

Usopp: Lets put it in the tank!

As a combined effort of Luffy and Usopp allow the shark to fall into the massive tank which is in a completely different room and in there is Robin, Franky, Zoro, Sanji, Nami and Y/N as they just watch the Shark go in.

Luffy: Has it come through! Has it come through!

As Luffy and Usopp come running down towards the tank.

Robin: Yes, Yes it has but its eating all of the small fish.

Luffy: SANJI!! FRY UP THAT SHARK!

As Luffy points towards the Shark.

Sanji: One shark coming right up Captain

As Sanji drags the shark over to the kitchen area and starts to prepare it. Meanwhile, Y/N is just looking at the Kanabo that he has as he starts to polish it. Nami comes up beside him as she sits down next to him.

Nami: Thats a nice Kanabo..where did you get it from

Y/N: I used to have another one when I was younger but that got absolutely decimated.

Nami: How?

Y/N: I lost. In a fight.

Nami: Against who?

Y/N: My rival..She was the one who absolutely decimated my Kanabo. It all started when...

7 Years Ago

Y/N: Ahh...what a day today.

As a younger Y/N is just sitting down on one of the rooftops of the flower capital.

???: It is a fine day indeed Y/N-Juro.

As Y/N hears a voice as he jumps off the rooftop to look at the person.

Y/N: Hello Shopkeeper-Dono! Fancy seeing you at this early morning.

Shopkeeper: And its weird to see you at this hour Y/N-Juro! I thought you would be chasing marines.

Y/N: Gotta take days off! I'll just have the usual

As the Shopkeeper prepares Y/N's favourite food.

Y/N: Thank you! See ya Shopkeeper-Dono

As Y/N waves the Shopkeeper goodbye as he starts to walk off away from the flower capital as he starts to eat the food.

Y/N: Finally!! I was star-

Y/N isn't able to finish his sentence as he sees someone coming down from the air as Y/N drops his food and grabs his Kanabo as he prepares to clash against the person.

???: I have finally caught up to you!! Y/N!!

Y/N: Huh? How do you know who I am? And why do you have a Kanabo aswell?

???: It doesn't matter. Now engage me in combat!!

Y/N: Very well.

As the person comes closer towards Y/N as he starts to smile which causes a shift in the person's movements but they don't falter as they clash in the mountains.

Y/N looked as if he was winning but the person was winning as the figure was able to completely smash Y/N's Kanabo and send Y/N flying into a rock.

???: You gotta try harder then that to defeat me Huh Y/N!!

As Y/N grabs the rock and throws it as the person but they are able to smash it as Y/N sprints towards the figure and punches the person in the face breaking the mask.

Y/N: Y-you are a...

Y/N: WOMAN!!!!

As Y/N backs away. Yamato starts to walk towards him.

Yamato: Whats wrong! Haven't seen a woman before!!

Y/N: I have!! But I didn't expect to be fighting one!!

As they both just start arguing with eachother as they eventually stop as Yamato calms down and Y/N calms down as they look at eachother.

Y/N: Hey... you need to replace my Kanabo!!

Yamato: I will don't worry!

Y/N: Next time we fight, I will break yours!!

As Yamato just looks at him at a sideways glance as Y/N looks at her again and they start to argue again until the night...
