Yata Mirror and Sword of Totsuka

[Baka Sennin]

they probably can, but like the other legendary items, they probably consume a truckload of chakra. itachi probably found a hack around that through susanoo, a manifestation of chakra.

they cannot be used without susanoo just because oro was searching for them doesnt mean that they could be used without susanoo he was also searching for the sharingan but u need to be uchiha

are you sure? kakashi is not an uchiha but he has sharingan, danzo has ten sharingans,
