Bro what is itachi actual susano ability ?
(Thoes who don't know his susanoo ability was not yata mirror and totsuka blade both are spirit weapon and spitit weapon can't be any susanoo ability in sasuke and itachi fight when orochimaru see totsuka blade and yata mirror he said "acha ye tumharey pass thea itey sallo sey" that means itachi taken or stolen yata and totsuka blade)
