Sword of Totsuka is a weapon carried by Susanoo that exists only in the user, being made up of chakra. Contained in a gourd held by Susanoo's third fore arm, the blade is actually the liquid inside the gourd that is released and shaped, rather than a conventional sword. This sword can also function as a sealing device. When a target is pierced by this sword, the user need only draw them back into the gourd that serves as a hilt which will keep the victim(s) sealed in an eternal genjutsu. This sword is only able to be used by Itachis Susanoo
