Is this really the end? Like wtf.
Zoro resembling Ryuma completely irrelevant.
Kaido probably had the worst flashback of the series, making him just a simple brute, strong villain without any nuance. Dying in a lava pit, without any citizen in Wano even witnessing what happened. No major deaths for allies, complete lack of tension, that's a complete miss in a "war".
If this is how Wano ends, this is definitely one of the worst arcs in one piece for me.
