A part of me still wants an extended backstory for Zoro. If Oda reveals he has a famous ancestor, then there will be discourse that Zoro was carried by his ancestor(s). I mean look at the discourse that is surrounding Enma. People still can’t accept the fact that Zoro had to tame it.
I think I want Oda to focus on Zoro’s fights from now to the end of the story. I don’t think he can handle an extended backstory for Zoro without ruining his character. If we get any flashbacks I hope it’s more of Zoro’s training with Mihawk.
