It follows narratively after he got Enma and how during his fight against King and his exclamation to be KoH he valued and recalled how he got each of his swords ie: showing his growth and intuition with each sword. Just after that he unlocked Acoc fully and independently.
Now he is going to complete KoH and get a black blade.
Bro he needs to meet Mihawk as a Black Blade user..
What does that mean for zoro:
- Shows worthiness as a challenger for the title of WSS balck blade user
- Embodying the legend of Ryuma (his ancestor)
- The next time he meets Mihawk its going to be it.
Him not having a black blade is going to be bitter.. It will shows that Zoro is jumping tiers in his fight against Mihawk which is not enjoyable. Him being worthy matters. He is not worthy of fighting Mihawk.
You are telling me that Mihawk told him bout how to get black blades just to transform his blade balck in his fight against him? Bruh
