Maybe Oda is showing that Luffy is the Acala Wisdom King because he drew parallels with Fudoo Myou and Gear 4th. But we haven't even seen Rox's face yet. We've only gotten a glimpse of Kaidou's flashback.
Kinda disappointed Kaido went out this way, but whatever... I want to get an update on the rest of the world. We've been stuck in Wano for what feels like 3 straight years. Also would like to get an idea of where the story is heading next. I'm guessing Elbaf.
