you still haven't answered why lol
there's no criteria for who does or doesn't get it.
fucking Yamato and Katakuri weren't ambitious and they had it lmao
what makes a Conqueror?
Well, the word for it, Haoushoku, really translated more to simply being like a King then an actual Conqueror, which is where I feel where the concept gets kinda askew. Because there are people who would be considered great and powerful rulers who never actually start wars. As a Conqueror, well....conquers.
So, I guess we have to look at more with someone with the charisma and determination of someone Kingly that puts them above others. That certain je ne sais quoi factor.
