Mifune was walking through the Streets carrying all of his Blades on his Back waiting for Blackstar to come back so they can begin to rematch.

Mifune: He should be here when I hear-

Black Star: YAHOO!! BLACK STAR IS HERE AND WILL SURPASS THE GODS!!

Mifune: I Hope you know that this will be A Fruitless Effort. My Ittoryu Mugen Sword Style is Unbeatable.

Black Star then stopped and got all serious.

Black Star: I said I am going to surpass all of the Gods and you not standing in my way.

Tsubaki: (Thoughts) Holy Crap! I Haven't seen him this serious since he's left DWMA Some time ago!

Mifune: Well, Give me your best attack. I'll Block it.

Black Star: RIGHT! I WILL! Tsubaki Uncanny Blade.

Tsubaki: Right.

Tsubaki then Turned into her Uncanny Blade Form as Black Star then began to coat it in Armament Haki.

Mifune: You Learned Armament Haki?

Black Star: I learned it from the Greatest Swordsman in the World.

Flashback!

Black Star: AAAGH!

Black Star slammed against A Wall as Zoro stood in front of with three Kendo sword coated in armament Haki.

Zoro: AGAIN!

Tsubaki: Zoro! Calm down! He won't make it!

Zoro: That's not an Excuse. You say you want to surpass the Gods?

Black Star: Y-Yes!

Zoro: Then you Must gone through what I had. When I Trained with Mihawk it was A Literal Hell, A Hell I could not Escape, as I Had to get stronger to become the world's strongest swordsman, and I'm still getting stronger right now. I Lost My eye to him. I'm going easy on you, and if I weren't you would lose more than an Eye.

Black Star: I... I...

Zoro: You What?

Black Star: I DON'T CARE!!! I WILL SURPASS THE GODS!!! I WILL BE THE GREATEST!!! YOU HEAR ME!?!?!? HUH!?!?!?

Zoro then smirked as He Handed Black Star another Kendo Blade.

Zoro: Then Keep up. I isn't Holding Back Kid.

Black Star: Thanks Master.

Zoro: Call me Zoro.

Flashback End!
