This is still unexplained yet. So still debatable. Even if this is the explanation GB should come in zoro way as obstacle to understand or achive bb.
Cuz how rare this is to the point only 2 in op history this is rarer than anything in op
....
This why just throwing bb to GB who is not only swordsman like shanks oden rocks roger is just a complete bullshit .
> only 2 in op history
?
First, isn't Imu also have a Black blade (Nemesis, and maybe Stigma)?
Second, there are only 15 renowned blades of the supposed 83 three numbered ranks that are identified in the manga, 5 of each numbered rank (5 Supreme Grade blades/5 Excellent Grade/5 Skillful Grade blades), two of these 15 are Black blades
There are also identified 2 Grade blades (not numbered rank) and 29 confirmed renowned blades of unknown rank (numbered or not).
And then there's Law's renowned blade, which supposedly has no rank (whatever that means).
What make you think Lolda won't pull more Black blades out of his ass? Like with Mythical Zoans?
