I wanted to rest a bit but that's impossible so here I am
I appreciate you guys' love for our boy, but at least pretend to be reasonable, you specifically chooses the machine translation because it fits your agenda more, same for this and same for the Kaido introduction
The term was 番人, watchdog is番犬
This magazine's theme is RIVALS yes, but it's Luffy's enemies
The characters on each rival's page are just people who the writers feel are somewhat more notable as that character's enemy
Unless you want to say Yamato is Kaido's rival and Jinbe is Katakuri's rival...
First line is "an emperor and called the strongest creature"
I've been saying it for almost as long as I've been translating
And regarding the df, their designs confirmed to be supervised by Oda
