Susanoo

Susano'o is a technique that creates a spiritual being resembling a yamabushi weilding the sacred, a mirror that's considered one of the three sacred treasures of Japanese Legend that's capable of reflecting all attacks, including Sasuke's final attack with the Kirin, as a shield in its left hand, and in its right, the legendary , also known as the. The Totsuga no Tsurugi, commonly sheathed in a sake jar held by a third hand growing from Susano'o's right forearm, is an ethereal weapon with an enchanted blade capable of sealing anything it pierces in an eternal dream-like illusion, and is described as the perfect counter to Orochimaru's Kusanagi Sword. Zetsu does however admit that this is only a legend, similar to how the Dead Demon Consuming Seal is said to imprison the souls of people inside the belly of a shinigami. Like the Amaterasu, and Tsukuyomi, Susano'o is the third and final ability of the Mangekyo Sharingan.
