"Compensate for lack of CoC" utter nonsense statement. Straight up. Mihawk HAS to have CoC.
Why the fuck else does Zoro have CoC for chasing the title Mihawk already has, but Mihawk does not?
People have been denying Mihawk the fact he turned Yoru the EXPLICTLY greatest sword in the setting black for decades, but Greenbum having a random unnamed and thus far non-ranked black blade on his hip, aka a Thriller Bark Zoro level feat? Does not all of a sudden allows you Admiral-stans to make definitive statements about their place in the series and how they are forged.
This is not how this shit works my guy.
Black Blades as Shusui shows can be picked up/stolen by people like goddamn Moria or more than likely Absalom since he likely snuck in and stole it.
Its not some sort of testament for Greenbull to have potentially accomplished an Absalom level feat of being close to a blck blade/touching it without dying.
He has literally not even be drawn to hold the thing in a single panel, and yet HE totally forged his black blade, while with Mihawk it was/is still in doubt?
Until proven otherwise, as far as I am concerned Greenbull picked that blade up from whoever was actually worthy of forging it because the character that has less association with swords than goddamn Luffy forging a black blade is comical to me.
