if getting visited by the reaper is what deems someone worthy for the BB, then the concept of BB was overhyped and pretty mislead
May be just that I like bleach but I like the idea that this is what’ll create the black blade.
I’ve always seen the black blade as the pinnacle of “swordsmanship” where the Will of the swordsman empowers the Will of the sword turning it black. Whereas most sword users cost their swords in haki without even caring about the Will of the blade they carry.
Enma has always been a very vocal sword of what it wants, as are most cursed blades. So Zoro understanding it’s Will first and creating a black blade through it is a good introduction to the concept
And it’d go with onimaru stating Ryuma forged a black blade with Shusui because Ryuma was eventually able to understand Shusuis Will in these fights
