exactly
sukiyaki didn't know shit about imu or maki so thinking maki is required for kokuto is dumb
Not really, it could honestly be another indication or Hint since even Top Tiers who had higher Haki than Oden can't even make it Black Blade too, Roger for example since he loves his sword so much. I see Roger as one of the guys that had pinnacle of Haki. And still couldn't make ACE as a Black Blade.
Also the things we knew are Black Blade only comes from many numerous battle by Gyukimaru which is gonna bs considering Zoro gonna done that faster than anyone at 21 with few battles lol.
If turning Black Blade only needing Haki on it.
Ain't that mean Zoro Haki even better than guys like Roger etc?
Worse thing is Sukiyaki didn't even bother to explained that.
