who the hell understands them
they have always ranted that if luffy defeats kaido, he will do it by luck, or because he is the protagonist, that luffy is still not up to a yonkou etc etc
And now, what is shown, not a defeat, because Luffy has not yet appeared defeated, but an attack in which he was caught off guard, they come and rant?
Are they idiots on purpose or are they trying to be?
