He doesn't count Neko's interaction with Marco, but that is still tied to the acts in general

-
Yeah. We never got a formal introduction to act 1 like we did to act 2 and 3, did we?
-
It doesn't say "Act 1", but the intro is similar with Hiyori or whoever that is playing the shamisen as the curtains open up on the play. It even introduces the crew that are already playing their roles. Act 2 opened mid chapter as well and Act 3 opens like a quarter in
-
Yeah I noticed also that unlike the start of act 1 and 2, at the start of act 3 their is some guy playing the flute. I wonder if that will continue.
-
I think it's being implied that the pirates and Denjiro are unaware of each other. Denjiro said he freed the prisoners, but there is no reaction from Law so far. We can't say it was definitively Drake or Denjiro yet. It can be someone else. Towards the end of the convo, Hawkins mentioned the alliance. Maybe it's someone that Law has been working with since before the PH alliance. We all know that Law wanted Doffy done in for the longest. Yet, his Sengoku convo and even Robin's warning to Luffy isn't for no reason. Law has either made his choice already or still unsure.
-
I think it was just Drake because him and Law go way back.

@Johnny:
Just a random thought: Isn't it odd that in the 25 years of his reign, Orochi's never had a kid? Or even married, for that matter.
plot twist:
Zoro is a Kurozumi Orochi hidden child
Zoro vs Orochi.. son vs father -
O-Tama could be his abandoned daughter
-
I'm very much against Zoro having a famous background, but I admit him turning out to be a Kurozomi would be hilarious.
-
zoro must somehow be related to either of the 5 main family in Wano.
anyway, what is the possibility of marines joining this battle?
as of now, we have 8 out of 11 supernova at wano, which most likely join the battle.
-
Just to sum-up all the sides currently in Wano:

Orochi Shogun Army (Oniwabanshu, Mimawarigumi) -
Can't wait for a chapter properly showing who of the BMP are in Wano (the anime showed a lot of faces that weren't seen in the manga like Snack and my girl Amande).
-

Zoro and orochi gettin their Luke and Vader moment. Join me son, together we can beat kaidou and rule wano together.
But tama would be good too, having her marry momo would put all their families conflict from the past behind and all the wano hate for orochis's family.
-
Im 50/50 about the Grand Fleet, in one part, they should arrive with the new probable newcomers in the Cover Story to make Luffy arise out of Wano as a pirate genuinely equal to the Yonkos.
But in the other part, no don't come, there's a ton of characters already. -
I dont think zoro is part of a family. But if he is than his green hair must play a role. Are there any colored versions of the family?.
Also… are the marines not currently "fighting" the 7 samurais ? I cant imagine that the marines have the ressources to take part in a war with 3 Yonkos (counting luffy) and a samurai faction they should not have any knowdledge of their power level while also fighting people like mihawk who would need atleast an Admiral level fighter to be taken care of and stuff like the kuja warrios which are a small army.
-
Well, as far we know, Koby explicitly said the marines were struggling to keep up with everything that's going on (hunting down the Warlords included, but presumably the incident involving Alabasta, what Sabo apparently did, the assassination attempt, the death, and whatever else Wapol wanted to leak, although I figure many of those things are related to each other), and it was implied that they would, in fact, not be making any moves in Wano. Actually, not just implied. Akainu literally said so.

The anime showed Snack? Hmmm maybe they got a heads up about future fights. I figured Oda hid Snack's full appearance far too much so late in Whole Cake because he'd join the trip to Wano. Both him and Smoothie seemed far too underdeveloped to be part of the Sweet 4, I just assumed Oda was saving them for later. I hope Snack is there.

Same, I’ve been saying this a lot recently
We’re def gonna get introduced to the flying six, Kaido’s son and the numbers very soon, but I’d like if Oda included the big mom pirate combatants and there bounties in the following chapters
Oda always does this, he has all the villains gather at one place and shows off the enemy commanders, so fingers crossed that’s what we get this new chapter

Thats true,altough i still find unbelievebable that the Marine will ignore two Yonkou allying! So in the end they will totally do something.
-
I wanna see Fujitora in wano. I hope the marines send him in, or maybe ryokugyu.

But the fact that Snack have already been beaten by a Worst Gen makes hims look much less threathening.

I think Borsalino and/or Sakazuki might end up going by the end of the arc.
-
Did anyone mention Zoro not having any resemblance of an alternate storyline is… a bit weird?
Wano, in theory was supposed to paralell Sanji's WCI, not saying it has to be, but there aren't any special care for him or his swordsmanship. Not even a foe at table.

I don't see how it's weird. It was just an assumption people had just because of the samurai aesthetic. Why people thought that would overtake the fact that this is an arc setup since Punk Hazard is beyond me.
Arcs like WCI or Enies Lobby only happened to begin with because of the respective Straw Hats those arcs focused on. Wano of course isn't happening because of Zoro, so I never expected such a focus. He'll get his new sword(s), a big fight, etc., but I never got why people, even now, saw him as the one that'd get the most focus.
-
Zoro's gotten a lot of focus, though? I can hardly think of other arc where he got this much. And we're just entering the climax.
-
Pretty much everything we were expecting to be part of Zoro's own storyline in Wano, Oda nonchalantly told us on the last SBS (why his village is called Shimotsuki, how Wado Ichimonji ended up there, how he connects to Kozaburo, what is the connection between Kuina's father and Wano).
-
I like how Blissed put it, Wano isn't happening because of Zoro. When thinking about it like that It's not weird at all but it does completely go against my expectations. I kept assuming Zoro would have some Sanji sized focus here just because Zoro.
All that SBS stuff is really cool, I hope Zoro finds out about it before they set sail. I would have liked Zoro to at least comment on it all though chances are he'd be like "oh interesting" and that would be the last we hear of it. Maybe when he visits his master back home they can have a long talk about it.
This late in the game I'm no longer expecting any Straw Hat to get the treatment Sanji did last arc. When Whole Cake started though I was like oh Zoro gonna get Wano, Usopp Elbaf and what ever else.
-

While that's true, the people that are making a stink about it here and there wanted the equivalent of what Sanji got in WCI. In that arc, no one had to question whether or not that was effectively a Sanji arc, it clearly was.

Well I actually could see it for Usopp, at least to some extent, since it's actually one of his dreams to go there, as well as the arc presumably being low stakes. In fact, that would be the first time a Strawhat's dream has finally come true. (Excluding Sanji obtaining invisibility lol) In comparison while Zoro had some interest in Wano's samurai, it was never his dream to go there or anything.
-
I still was expecting some side-quest that'd be concerning for him -rather than this, which is: I gotta beat whoever it is they put in front of me.
Orochi is there for him, but he is there much much more for any other Samurai at this point, it's nothing special. Even if he fights him it's gonna come down to Orochi's own stupid overconfident of 'hey I got 8 swords' being overpowered by Ashura. Hoping at least we can get some fire-related stuff… And I'd really take anything related to Zoro-not-as-a-fighter.Because it is what Zoro as a character is reduced to be. It was refreshing to see him laugh and shit a couple of chapters ago but I think more should have been done for his character. Yet, what he gets are a sword and just another fight. Oda still does have a room with the previously written Hiyori scenes and little attachment he had to Yasuie. Maybe introduce a flashback when he visited Ryuma's grave...
It's not about high screen time but rather the arc that could add to Zoro's character and history/story is a bit thin in content tailored for him, so far. And the build-up stage seems over.

The thing is, out of all the Straw Hats, Zoro is the only one who doesn't need a loyalty mission. He already proved that in Thriller Bark when he gave himself up for Luffy. Remember, Zoro had told Luffy that his dream would greater than his loyalty to Luffy but he sacrificed that dream to let Luffy achieve his.
Every arc that has been centered on a certain Straw Hat has been a mission to reinforce that crewmates loyalty to the crew. Nami> Arlong Park, Robin> Enies Lobby, Sanji> WCI. I think the only ones left who need a major loyalty mission are Ussop and maybe Franky.
HOWEVER. Its very weird that Zoro isn't at least having duels with all these Swordsmen. Seriously, what does it mean to become the strongest swordsman in the world. Is it just beating Mihawk? How does he know there is someone who is not better than Mihawk in Wano.
This is the one thing I had expected in Wano. Zoro picking fights, or finding ways to pick fights with various Swordsmen, -
I'm still bothered by the fact that Chopper and Robin still haven't gotten their numbered chapter title, like the "The Fifth" and "The Sixth" like every other crewmember did. After Usopp got his after rejoining the crew following his fight with Luffy in the Post-Enies Lobby arc, while Robin did not, I figured Oda has something else planned for her and Chopper in the future. But it's been a long ass time since then and it looks more and more unlikely.

I do think Chopper could benefit from one of those arcs. Off all the Straw Hats, he's been the most grossly underutilized of them in the New World. Law made him look like an amateur in Punk Hazard, and he was almost a non-presence in Whole Cake.
Maybe something related to the Minks when Zunesha inevitably dies? He does like them, having a crush on one and being super close to Carrot.
-
Well, since Electro seems to be based on fur, one would say Chopper would easily learn it.
But electricity has become so much of a signature for Nami that it's quite hard to imagine it.
Anyways, since Luffy also does it, and electricity should be a mayor feat on Shogun Franky as well, maybe Oda thinks of electricity the same way how he thinks of fire(which Luffy, Sanji, Franky and Usopp all use it), and Chopper could actually give us the surprise with Electro here in Wano.
-
nah.. aside Electro, I really wish that Chopper can achieve Sulong Form also as a higher transformation than Monster Point..

I really don't see Chopper having a crisis of loyalty though.
Nami didn't trust anyone and wanted to fix things by herself. Robin felt like her existence posed an inherent danger to the crew that accepted her. Ussop felt like his weakness meant that he was disposable member of the crew. Sanji felt like his past defined who he was and therefore he was replaceable and could sacrifice himself for the crew.
Chopper though, what could cause chopper to question his place on the crew?
The only one I can see going through something like that is Franky. Franky never had a moment where the Straw Hats intervened in his life directly. His story was intrinsically tied to Robin's story. Plus out of all the story hats, I would say he is the most replaceable. He's already built the Sunny. He doesn't really actively add anything to it. So he is basically tagging along to make sure the ship he built is functioning.
Why does Franky have undying Loyalty towards Luffy and the Straw Hats? Out of all them, he is the only one who doesn't have a strong enough reason.

He could fail to treat someone, I dunno.
The first thing that came to mind is Zunesha. We know the elephant is close to dying and the Minks might need Chopper to do something and split from the Straw Hats. It's suspicious though that Chopper never got his the "Fifth Person" chapter.

Guess that would be saved to a Vegapunk arc…
It's also worth noting that we still don't know much about Franky's past before being adopted by Tom. The same way Sanji was from the North Blue, but ended in the East, Franky was from the South, but apparently lived among pirates until reaching Water 7.
Brook also has a lot of mystery about his origins. We don't know his homeland and have no idea about his childhood. We only know he was part of an army in the past.
-
Maybe there is some surprise for Nami too. Bellemere found her and Nojiko at sea, when she was a marine. I always imagined that Nami would discover she was a princess of some far aeay kingdom. Guess that storyline was used with Vivi and Sanji already….
-
I have to wonder where all the enemy forces are gonna go. In the past it's been the navy or royal guards who took care of clean up and detainment, but Wano is closed off, in a weakened state and facing numbers greater than any island before it. Some are definitely gonna escape, but they've got to be kept from coming back somehow, or they'll be free to do just that once the alliance breaks up and Luffy leaves.
What will compel Kaido not to just try again later? Unless he and BM start actively racing the SHs the last Road Poneglyph and One Piece, that could do it. But still, the logistics of keeping the remaining enemies in line after all this is mind boggling. I suppose Udon will be utilized a fair bit: I can just imagine some of the old guards being set to work in there, with maybe slightly better treatment.

Isn't the Sunny a sufficient reason ?
-
Isn't the Sunny a sufficient reason ?
well, Franky is the Engineer. Sunny is his masterpiece. Of course his presence is needed on board and loyal to the ship captain.
-
I think you're all missing the original point. The 'Xth person' chapters are specifically about people joining or re-joining the crew. So in order for Chopper or Franky to get one, they wouldn't just have to get a big focus or do something important, they'd need to specifically leave the crew temporarily. Something like Sanji in WCI at least (although he already got his 'Xth person' chapter back in East Blue).
Wait, it looks like I'm the one actually missing the original point. Well, never mind then.

Franky already got his X chapter, alongside Usopp.
Only Chopper and Robin don't have theirs, which is quite strange for the latter since she's undeniably part of the crew now.

Yeah, I was gonna say that too at first, but then I saw someone else had brought it up and realized the talks about Chopper and Franky had nothing to do with that.
-
back to this Wano topic, if its true that Act 3 will ended with tragedy, maybe it was Hiyori will be killed or heavily wounded rather than having samurai devastating defeat.
-
I'm really thinking Oda is just saving up Chopper(five/go) and Robin(six/mu), to get one of his dad jokes done in a cover.
After all, Usopp and Franky got one together as well, and yeah, Oda have been deliberately avoiding it, despite the fact that Chopper could have perfectly got his after Drum.
Chopper and Robin have been actually getting along pretty well lately, it's just that they have been separated for most of the Alliance Saga, however, if they do get for example, to fight together here in Wano, that's would be it.
-
I feel like Oda would have adressed the chapter titles in a sbs or something if he simply forgot about them though.
-
Isn't the Sunny a sufficient reason ?
Not really.
Its like Tom wanting to sail with Roger just because he built the Oro Jackson.
Plus this actually raises a very fascinating question. What would Franky do if the crew was faced with a similar decision to getting rid of Merry.
Would Franky really stay with the crew? After all, the Luffy and crew don't need the Sunny anymore, so they can either go with Franky or get another talented Shipwright.
When Zoro, Sanji, Nami, Ussop, Robin, Brook, Chopper and Jinbei say they are completely loyal to Luffy, I believe them because I know what it took for Luffy to earn that loyalty.
Franky on the other hand joined because the crew is sailing on his ship. Its like someone gifting you a car but insisting they always ride along with you because they helped build the car. Franky has no personal reason to be completely loyal to Luffy.
In fact, he is the only crew member who was recruited/joined as a sidestory to a larger story. Every other straw hat has had an arc devoted fully to their recruitment.

If the Strawhats were faced with a similar decision to getting rid of Merry, it would mean that Franky had failed in achieving his dream, i.e. building a dreamship that will concquer any ocean and sail to the end of the world, which is the reason he went out to sea in the first place. I'm not sure if he'd continue sailing with the crew anyway, but his spirit would certainly be broken. It's like if Brook would find out that Laboon had died in the meantime and he'd never be able to achieve his dream of keeping his promise to his old friend of one day returning. Would Brook still continue on his journey with the Strawhats?
I do find this debate about who of the crew are most and least loyal to Luffy pretty interesting. I'd say Nami, Robin and Sanji have the greatest reasons to be completely loyal to Luffy because in each case, he risked his life and went out against all odds just to help them and save their lives. While he did more or less save the life of each crew member during their joining arc, it was most often a byproduct of achieving some other goal: getting rid of Don Krieg or Wapol, rescuing Robin, getting back the crew's shadows from Moria etc.
As for Zoro and Jinbei, they just seem like extremely loyal people in general, so it's very difficult to imagine that they would ever go against Luffy. That leaves Usopp, Chopper, Franky and Brook. Usopp is probably the one most loyal to Luffy of this group, both because he has been with him since almost the beginning of his journey and they've gone through some personal hardships together that really strengthend their bond.
As for the other three, Chopper owes Luffy a lot because he truly helped him come out of his shell and gain the courage to go see the world. It's very clear that the Strawhats are truly a surrogate family to him. Brook and Franky are pretty similar to me. Both owe Luffy because he helped them out of some very desperate situations and both gained a lot of respect and sympathy for the Strawhat crew during Enies Lobby/Thriller Bark. Lastly, their big dreams neatly coincided with Luffys dream and his personal wish for them to join his crew (one shouldn't forget that Franky didn't just simply join the crew, but needed tons of convincing to leave Water 7 due to his own feelings of guilt).
So yeah I guess I'd consider Franky and Brook to be the two members of the crew who have the smallest reasons to be loyal to Luffy. Still, I have a really hard time picturing them ever betraying Luffys trust or seriously considering leaving the crew.

I can definitely make a case for Brook's loyalty.
In my opinion, Brook's loyalty to Luffy(Note that since the Time-Skip, Brook is one of the few SH that has repeteadly reiterated his loyalty to luffy) is not rooted his quest to meet Laboon. Rather, meeting Laboon is just going to be a by-product of sailing with Luffy. So yeah, if Brook heard that Laboon died, he would stay with Luffy and help him achieve his goal. This time he just won't have a personal goal to strive for.
Brook's loyalty to Luffy is based on the fact that after decades of Loneliness, Luffy was the only person who met him and immediately offered him his friendship. Just consider Brook's character and flashback, he is a man that thrived on interacting with others. His essence as a musician is based on being around other people and entertaining them. But due to his Devil Fruit and Morai's curse, he was cursed to sail alone, telling himself dumb skull jokes. And then Luffy shows up and offers him his hand at friendship with no expectations.
To someone who has experienced such terrifying loneliness, they would offer their life to anyone who could offer them something else. So IMHO, Brook is loyal to Luffy because he rescued him from a lonely and depressing life. Heck Morai stealing his shadow could be interpreted as Brook losing all the things that made life worth living, so he could only live in constant darkness.
