Itachi’s Susanoo sword is called the Totsuka-no-Tsurugi, also known as the Sakenagi Longsword or Sword of Longevity. It is one of two weapons that Itachi’s Susanoo wields, the other being the Yata Mirror, a shield that is said to be able to deflect any attack.
The Totsuka-no-Tsurugi is a powerful and legendary sword in Japanese mythology, said to be wielded by the god Susanoo, the brother of the sun goddess Amaterasu. According to legend, the sword was created when Susanoo defeated an eight-headed serpent known as Yamata-no-Orochi, and it was passed down through the generations until it came into the possession of Itachi.
The sword itself is unique in that it is said to be able to seal away any opponent it strikes, trapping their soul in an eternal dream. This makes it an incredibly powerful weapon, as it can defeat opponents without causing them physical harm.
In the Naruto series, Itachi’s Totsuka-no-Tsurugi is depicted as a long, curved sword with a blade made of an otherworldly substance that glows with a blue flame. The sword is sheathed in a sake jar, which serves as a unique and unusual scabbard.
When Itachi activates his Susanoo, the Totsuka-no-Tsurugi is unsheathed from the sake jar and becomes a part of the armored form of the Susanoo. The sword is wielded with incredible speed and precision, and its ability to seal away opponents makes it a formidable weapon.
In addition to its sealing ability, the Totsuka-no-Tsurugi is also depicted as being able to cut through almost anything, including other powerful weapons and defenses. Its unique properties make it a valuable asset in battle, and it is considered one of the most powerful weapons in the Naruto series.
