Reading Volume 113 coz I'd like to re-read the Harald flashback and this Conquerors's Haki panel came up and I kinda have a few thoughts on it so I'll share.
Code:
どうやらは覇王色があるのは一人じゃなさそうだな
Gaban: It seems like there's more than one of you that posseses Conqueror's Haki
俺か!?
Sanji: It's me right!?
やっぱりそんな気がしていた
このままマリモやジンベに株を奪われ続く
Sanji: I knew it! No way I'm gonna let that marimo and Jinbe keep stealing my stock...
そこの剣士...!!だいぶ体に馴染んでるようだ
Gaban: You! Swordman over there! Seems like your body is already accustomed to it
!?
Zoro: !?
俺ア「覇王色」を使えのか?
Zoro: Huh? I can use conqueror's Haki?
ええ!?お前しらなかったのか!?だだ漏れてんぞ!?
Luffy: What!? You didn't know! It's literally pouring out of you!!
呆れたな覇気を認識してできてこその”力”だ!
Gaban: Really...I'm lost for words. Haki is a power you can only fully make the most of when you are concious of it
お前そんなことで「四皇」の船長を支えていけんのか!?
Gaban: Are you really trying to support your Yonko captain in that wishy washy state!?
おいじじ俺が!?
Sanji: Hey old man! what about me!?
First on Gaban's initial statement
```
Gaban: It seems like there's more than one of you that posseses Conqueror's Haki
```
Like English fans, since this chapter, Japanese fans have also been discussing this phrasing saying that if it was just Zoro Gaban would've phrased the line differently which is true but I think both fanbases over focusing on that phrase and missing more important context which serves as more conclusive evidence which is Gaban's incredible CoO prowess which has been emphasized time and time again this arc.
If Gaban was only referring to Zoro, he won't have phrased in a way that seems that he's only just been able to confirm his suspision and this is proven by Luffy's reaction to Zoro not realising that he has it here.
```
What!? You didn't know! It's literally pouring out of you!!
````
Luffy is basically saying that it is bloody obvious so there is no ambiguity what so ever about Zoro having CoC in which case, wouldn't that make Gaban's statement odd if he's referring to Zoro here. Keep in mind that he's met Zoro prior to this incident together with Luffy and Nami in the castle so there's no way he didn't realise it after spending that amount of time with them so he's clealry referring to Sanji here.
Another thing that I think we've missed here is Sanji's comment as well which is probably being played off as a joke but again like Gaban, Sanji Observation Haki is very keen and he's kinda opposite to Zoro in the sense that he's a lot quicker on the uptake, so this statement I think is being taken as a joke but! Sanji himself might realise that he has it. I mean we've been told since Wano via Kaido that characters can sense conqueror's haki even without it being used. So it's possible that Sanji being so keen with observation Haki vaguely realizes it in himself. It's a good contrast btw Zoro and Sanji being, Zoro who's actually manifested it with it literally pouring out of him is a little slow to realise where as Sanji who hasn't really manifested it yet can somewhat feel it in himself.
```
It's me right!?
```
```
I knew it! No way I'm gonna let that marimo and Jinbe keep stealing my stock...
```
Now before we go wild lol there's also one addtional thing I want to point out which is what Gaban stated after that and the reason why he singled out Zoro in particular. I will also add Gaban's statement to Luffy and Loki's statement to Gaban which happened before it as it's related to the point I'd like to make.
```
Gaban: You! Swordman over there! Seems like your body is already accustomed to it
```
````
Really...I'm lost for words. Haki is a power you can only fully make the most of when you are concious of it
````
ガバンお前の話で腑に落ちた
俺は自分の力を言語化できててなかった
Loki: Gaban, thanks to your talk I understand wholehearteadly now
Loki: Until now I've been unable to put my own ability into words
```
```
おい...”麦わらのルフィ”
覇王色の使え方肝にめんじろ...
あいつらは決して不死身はない...!!
Gaban: Hey..."Strawhat Luffy"
Gaban: Don't just use it! Understand how to use Conqueror's Haki!
```
Looking at the above there is a lot of emphasis on acclimatization and utlitiy of conqueror's Haki so unlike Sanji for example who isn't yet acclamatized to conqueror's haki there is focus on Zoro because not only is his body already used to it even if he's a dumbass that is yet to even realise it (basically a natural at it) he's quite literally blessed with it to the point where it is overflowing out of him so he can already use it unlike Sanji for instance who still hasn't manifested it. To be able to fight the immortals having CoC alone is not enough, you have to first be acclimatized to it and also understand how to utllize it properly. Zoro atm can probably fight immortals off the bat but he's a bit to dim to realize it hence Gaban's statement here:
```
Are you really trying to support your Yonko captain in that wishy washy state!?
```
Given the above context Sanji's statement here to Gaban and the fact that he was calm after whatever conversation they had becomes pretty predictable
```
Sanji: Hey old man! what about me!?
```
Gaban's hidden words: I can sense that you posses it, but seems like you're not able to manifest it yet.
So question is does Sanji manifest it and if he does will he able to properly utilize it to hurt immortals?
Given there's focus on first "acclmatization" and then "proper utlitly", imo it's a bit hard to tell.
What I will say though is that this whole Conqueror's conversation about only being able to properly utilize an ability by understanding it also applies to Sanji with regards to "PoL". Doesn't seem like Sanji really understands what PoL really is so he I reckon he will also get a proper understanding of it this arc.
Now I don't want to be the bearer of bad news but over focusing on CoC in comparison to Zoro imo is a losing battle given the focus being put on Zoro's CoC and the sheer volume he seems to have. All indications are that Zoro is a natural at CoC and that he has a lot of it volume wise to boot so even if he is not especially deft at using it, he will 100% be able to utilize the method Roger and Garp used against Rocks except that unlike them he will probably not be down and out simply by overusing it so again Sanji having CoC is great but personally I'd rather a proper development route with PoL rather than CoC.
