The entire Luffy-Nidai thing feels like a waste of time, especially now that Zoro picked up Enma... Like the only reason was simply telling us that the sword is in Wano.
So who's gonna wield it in the future?
It's quite a famous and powerful sword, and I don't see any character who's relevant enough to get it beside Zoro.
Right now I'm thinking that at the end of the arc Zoro will pick it up in exchange for Sandai Kitetsu. Tenguyama will see that, having mastered Sandai (& Enma), Zoro could be the right person to carry Nidai and will offer the swap.
Other ideas?
