I'm sorry, but this was really bad.
It almost feels like Oda completely forgot what was supposed to be the point of the Flashback, got lost in the Roger-wanking for a full month, then realized it and rushed back on tracks, resulting in the mess that is this chapter.
First: Oden had is family and friends attacked and hurt, his rule usurped and his country invaded buy foreign pirates who are exploiting its people and polluting its environment. Christ, he even realized the usurper has gone full Dio Brando and poisoned his father to death. But hey, they have the invincible barrier fruit, what can you you do about it? Of course wait 5 years just to fill in for what looks suspiciously like a minor plot-hole…
untill a charachter previously unknow both to us and Oden is introduced in a mini-panel where we are told that's she's a nice person, and promptly killed the next page. Now THAT is what calls for the badass walk-to-arlong-park-esque split page of the scabbards.
Second: Toki, the time traveler lady who comes from the mysterious past, the very same past our interim hero has supposedly just discovered something HUGE about, still has the charisma, the depth and the development of a shallow puddle. In a flashback that was supposed to be mostly focused on her, she gets less panel time than Buggy the fucking Clown.
Nami-face #476 (but with makeup and black hair! so that you may confuse it with more recent robin-faces), damsel in perpetual distress, there you go, A+ female charachterization.
Third: nobody at all seems even remotely interested in the Whys and Hows of Kaido's regency. Well, I am.
It's really baffling how 5 whole years with a lot of potential that could be used to explore crucial charachters like Toki or Momonosuke, give the slightest stake and emotional involvement for the readers are instead completely wasted in a few repeted panels of Oden being a buffoon and paesants scorning him. Until SUDDENLY, THE PLOT HAS TO BE PUSHED FORWARD.
It's just a pity.
