This chapter felt like an anime episode with all these flashbacks. Completely redundant and felt really out of place, like why are you trying to dive into those samurai now at the climax of the Kaido fight? That's like if we got a Vivi / the rebellious army flashback just as Luffy was about to deliver the final blow to Crocodile. Assuming this is the climax of the fight I can only say that this felt like a very lazy and poorly implemented use of content, but shit writing does not surprise me with this arc anymore
