Not even Shanks Roger or Oden could accomplish this feat who rely nothing but their swords unlike gb. Sorry bro your boy is not joining Ryuma and Mihawk ranks too many great swordsmen failed to accomplish that heavily df reliant admiral will not do the impossible. For people that don't respect Mihawk why cling to kokuto even when you must abandon all common sense to push this agenda something doesn't add up
But that Is fine: you think he isn't up to the task; maybe he isn't, maybe he Is, It's ok. We don't know how you actually do It, but it's fine.
What is laughable Is the "random shitty admiral" part.
We had Admirals fighting WB and Roger. Garp too wasn't one just because of the CDs problems, but he was in fact that; his pupil anyway dreams to be one. Akainu too Is one, and so on.
If anything, Admirals, Emperors and so on have a shot at doing it.
Also, It doesn't change much anyway: simply, if he really did It, It means that he Is more than what people thought he was.
