Here's what happened.
Zoro kept talking about how facing yonko is serious business, got mad at the yasuie stuff and so on.
Accepted to trade his strongest blade for one that managed to slash Kaido, without being turned into a permanent black blade.
She sucks his haki when he uses it and he takes it back.
Says that when he is able to control it, he will become much stronger.
He controls it, since he used a fucking named attack without drawback.
Did nothing.
He says he needs to "release" the weapon more.
What conclusion should I take from it?
Zoro nerfed himself on purpose before the big serious fight he was talking about, and is STILL nerfed by not mastering Enma completely before the final battle?
Zoro actually got buffed, but still cant do shit, so he needs the SWORD's power to help him?
Pick your poison.
