What a chapter! First "mind-blowing" one in quite a while (despite some issues, I'll get to that later).
God, did I love to finally see some real brutality and death in this series! Way to go, Oda! I swear he was watching the movie "300", when he drew that whole Kaido-Orochi sequence.
This time I'm actually quite confident a character really stays dead. There's no way Oda can backtrack on that (he literally beheaded Orochi, with nobody there to help Orochi, and we also saw the blood + head).
edit: Well, completely forgot about Orochi's mythical hydra DF ... sigh.
Two things though:
1) Luffy promises Yamato to take off her handcuffs, which are revealed to be the same that Luffy & Co. wore in Udon. Why on earth doesn't he do it on the spot? He has learned advanced CoA now and he could already take off the exact same collars in Udon (from himself and grampy Hyogoro). That is some PIS right there ...
2) Speaking of Yamato, I really like her personality ... but why oh why did you have to give her a carbon-copy of Nami's face, Oda? Come on man, it's not that hard to draw unique female characters.
3) This English translation was a travesty. Who on earth translated that chapter, a potato?
