So let me get this straight, Oden barges into the castle after hearing all of the atrocities Orochi committed to take his head. He gets stopped by Grandpa and Grandma Kurozumi, and instead of trying to fight their old asses and Kaido as well he.... believes them when they say they need 5 years to build a ship and leave, giving up the title of Shogun and a base of operations for the Beasts Pirates for no reason? And that he needs to dance naked in order to save the people he arrested for barging in the castle in the first place? Damn man, I mean Luffy is dumb and all, but I don't even think he'd be this retarded.
