The myth of Wano being full of Ryuma's is the only thing that stopped Akainu from giving out justice. Kizaru had no issue going up vs the combined forces of Big Meme and Carp boy.
If an admiral has an issue with doing their job...
I mean do people say the marines are too scared to fight the yonko? Or do people say even if they fight, they can't do anything; such as in marineford when Kizaru tried to take Whitebeard's head but stopped by marco? Or Akainu couldn't pass marco, and then Shanks in marineford? Or Sengoku when he failed against Blackbeard?
When will you marine fans learn;
- the job of the marines; is fighting against pirates
- the job of the pirates; doing whatever they want
Pirates don't have an obligation to fight marines, their job is not destroying the marines, they are usually after the treasures and other valuable things, fighting with the marines for no reason is stupid for them.
The marines have an obligation to fight the pirates,
their only job is destroying the pirates.
When you understand this it's easy to figure out who is stronger and who is not.
