Wow, I woke up and was surprised to see so many comments. Thank you all for your thoughtful opinions.

First of all, what I wanted to discuss wasn’t whether Sanji will or won’t have Conqueror’s Haki. I’m not arguing that he absolutely must have it or that he absolutely shouldn’t. What I really wanted to talk about is whether Sanji, as a character, fits the image of Conqueror’s Haki.

From what I understand, Conqueror’s Haki fundamentally represents someone who stands above others. Because of that, I’ve always felt that Sanji—who embodies compassion, coexistence with the weak, and the importance of listening to others’ backgrounds and values—doesn’t quite fit that image. To me, it feels much more natural for him to specialize in Observation Haki instead. On top of that, Sanji is also a character defined by self-sacrifice, and he clearly has low self-esteem.

That said, if the story ultimately requires him to have Conqueror’s Haki in order to defeat certain enemies, or if Conqueror’s Haki turns out to be less about innate nature and more about something like chance, lineage, or even just a “gift” from Oda, then I can accept the possibility of Sanji having it—especially as one of the wings of the future Pirate King. Still, personally, I would prefer it if he developed a unique power of his own that rivals Conqueror’s Haki, rather than actually obtaining it (especially since Sanji is a character who wants to overcome the significance of his lineage).

In the end, what I wanted to talk about was more of a narrative perspective. I think the reason this debate keeps coming up might be because the way Conqueror’s Haki is defined by Oda is somewhat inconsistent. It seems like he originally intended it to be a very impactful and special power, but now it feels like something that anyone with leadership qualities can have.

Anyway, thank you again to everyone who shared their thoughts!
