A sizeable team works on the series.
As for Oda going digital, you'll note that he does a lot of that kind of work for side projects.
Messages to other authors, online promotional material, and the like. He likes the convenience of digital artwork, but I don't think it's changed his mind regarding how to 'best enjoy' comics.
Hi Greg
Do you think Zoro fans will be happy this arc? I mean ever since time skip started Zoro has kinda been on the backburner….just getting his solo fight and then disappearing from the plot.
Now of course I'm not expecting his own arc like Sanji just had considering how many WG members and other major players are on the island...but do you think he will at least participate in the plot this time?
Seems like we barely saw him for a chapter or two and he once again went MIA... really hope Oda delivers since Zoro feels way underused post skip
