Call us crazy for believing in ZKK but you gotta admit, coincident or not, the amount of "hints" are insane. Like shit, even the fucknig sword that Zoro inherited from Oden/Hiyori is called Enma, KING OF HELL, you know, the one who guides the dead. Like, is it intentional from Oda, or it's just pure concident? But until Wano is over, we will keep believing in ZKK, because there's actually solid evidences that it's gonna happen.
