I know about the year of sanji but that doesnt mean = his arc. They clearly meant he will have alot of screen time focus which he did. And either way that doesnt mean wano is not zoros arc.do you think it makes sense for oda to give sanji his own arc but not zoro?
All this build up and portrayal, Zoros connection to wano back in thriller park. His connection with shushui and enma. Zoros background and the possible connection of his bloodline to wano. Enma and oden the parallels between oden zoro and ryuma his interaction with hiyori and etc. And still not his arc? Cant ignore all this.
Thing is tho in a lot of arc
zoro gets a lot of focus in general
especially when he is present (excluding wci, mf , impel down)
him getting massive feats/focus doesnt make it his arc imo
its just how oda writes zoro most arcs .
