@Red Admiral Agrees Mihawk has stronger CoA, Its CoC that he won't agree.
But if CoC is end all be all for swordsman and key to black blade, doesn't that mean Mihawk's CoC > Saint Shanks CoC?
I CAN agree on Mihawk CoA > Saint Shanks's CoC
but I don't know how do think it's even possible for Mihawk's CoC being above Saint Shanks and Roger ...
is Mihawk a HIGHER KING than Saint Shanks and Roger?
each GREATEST pirates of an era
do you HONESTLY can even say that without laughing?
I don't know how black blades are made
but at BEST case it should a hybrid usage of CoA and CoC
while Saint Shanks and Roger should have a higher level of CoC usage above lighting CoC
a power equal to Gura Gura (the only logical way to assume Roger = Whitebeard)
and I DON'T think black blades are equal to Gura Gura :)
