Among the ninja weapons Sasuke uses in the manga Naruto apparently his favorite is the kusanagi sword. Let's see together what functions this blade has.
While keeping the same name, the sword is used by the last Uchiha It's a replica of the original by Orochimaru. It represents value and is inspired by one of the three legendary treasures from Japan, along with the Yasakani no Matagama gemstone and the Yata no Kagami mirror, each corresponding to benevolence and wisdom. The legend from which the Mangaka were inspired for making the weapon tells of a clash between the god Susanoo and the eight-headed serpent Yamata no Orochiin which the first found the blade, which he later gave to the goddess Amaterasu.
In the series came the original sword of the legendary ninja produced in line in the body of the antagonist. The latter could then control it remotely and extend the blade at will. The fate of this weapon remained unknown according to the seal of its owner.
Sasuke's instead, it has less specific properties. Given by Orochimaru himself, it's called a chokuto, or a sword with a single straight blade. The Leaf Ninja uses the weapon for channel their techniques into it with lightning chakra.
As the manga progresses, it will pass through the hands of Itachiwho will use it in battle with Kabuto, and from Madarawith which he will inflict a wound on Sasuke. After that, it is discarded and replaced by its owner. This implies that the sword Sasuke possesses in the sequel Boruto is no longer the Kusanagi.
Interestingly, in this case too Japanese legends and religions intertwine in the elaboration of the plot of Masashi Kishimoto's work. What do you think about it?
For those who are interested, I'm bringing back a funny Naruto fanart and a Sakura Haruno cosplay from Naruto.
