SBS Volume 51
D: Are Kizaru and Akainu stronger even than Aokiji? P.N. Osumansan
O: Hahh, hahh... Sorry for the late introduction. Hello. I'm the author, who got his Balls Flattened by a Reader... you can call me Balltender. But who cares! Here's a question...YIKES!! What the hell is THIS?! Kizaru?! Get outta here! I'm gonna have nightmares! Sorry P.N. Osumansan, Kizaru's already appeared! He'll show up in the next volume.
Actually, you're not that far off, though.
The Pre-TS Admirals order was Sakazuki > Borsalino > Kuzan. Reflected in their Marineford matchups with Whitebeard > Marco > Jozu.
- Has been matched with Marco, Rayleigh and Benn Beckman. What do they all share in common? Being the RHM of a crew.
- Has unresolved conflict with Zoro from Sabaody Archipelago.
- Is Fleet Admiral Sakazuki's strongest man just like how Zoro is Luffy's strongest man. (read above).
Besides, what is even the argument for Sanji vs Borsalino? "Speed and Kicks"?
The only time Borsalino ever used kicks was against fodders and small fry who didn't matter. The only time he was matched up against a top tier in a serious duel (vs the Dark King), he used a sword. He has a named sword called "Ame no Murakumo", named after one of the sacred imperial regalias of Japan.
There's more going for Zoro vs Borsalino narratively than Sanji vs Borsalino.
