Guys did you noticed that Zoro scar at his eyes & Rayleigh that seem to be connected? From previous manga episode, Rayleigh used a sword vs Kizaru . Is it both of them having some sword training?
For else, Rayleigh have haki equipped. But how about Zoro? He trained with Mihawk & i can't wait he defeating any shichibukai/admiral/pirates with new power.
