The thing I wonder about the most is how long Sandro is going to drag this arc. 3 years? 5 years?
It's going to be multi-stage, at least the final battle guarantees that, but I've been thinking about how we might get some surprises down the road. Like a special arena that two people get stuck inside or special items they might find. Something like Usogui's final arc where it's a big arc split into different segments. Sandro can afford to do nothing but fights but I want to see him shake things up. It's the last arc after all and any author would want to get everything out of his system
